Network address translation NAT is the process of modifying IP address information in IP packet headers while in transit across a traffic routing device. There are two different types of NAT NATStatic NAT The simplest type of NAT provides a one to one translation of IP addresses. It is often also referred to as one to one NAT. In this type of NAT only the IP addresses, IP header checksum and any higher level checksums that include the IP address need to be changed. The rest of the packet can be left untouched at least for basic TCPUDP functionality, some higher level protocols may need further translation. Basic NATs can be used when there is a requirement to interconnect two IP networks with incompatible addressing. With static NAT, translations exist in the NAT translation table as soon as you configure static NAT commands, and they remain in the translation table until you delete the static NAT commands. Dynamic NAT Dynamic NAT has some similarities and differences compared to static NAT. Like static NAT, the NAT router creates a one to one mapping between an inside local and inside global address and changes the IP addresses in packets as they exit and enter the inside network. However, the mapping of an inside local address to an inside global address happens dynamically. Dynamic NAT sets up a pool of possible inside global addresses and defines matching criteria to determine which inside local IP addresses should be translated with NAT. The dynamic entry stays in the table as long as traffic flows occasionally. Exploit, VB. Net, VB6, CCSharp, Borland Delphi, Java, VBScript, CC, JavaScript, Visual Basic.

Dynamic translations have a timeout period after which they are purged from the translation table. PATStatic PAT Static PAT translations allow a specific UDP or TCP port on a global address to be translated to a specific port on a local address. Static PAT is the same as static NAT, except that it enables you to specify the protocol TCP or UDP and port for the real and mapped addresses. Static PAT enables you to identify the same mapped address across many different static statements, provided that the port is different for each statement. You cannot use the same mapped address for multiple static NAT statements. With static PAT, translations exist in the NAT translation table as soon as you configure static PAT commands, and they remain in the translation table until you delete the static PAT commands. NAT Overload or PAT It is common to hide an entire IP address space, usually consisting of private IP addresses, behind a single IP address or in some cases a small group of IP addresses in another usually public address space.

Ok, Router is wg3562 16mb, Garrage ZBTWG3526 GoldenOrb Build 20170701, due i did not get hurricane work due kernel, instead i got modem to have two connections. This type of NAT is called PAT in overload. The dynamic entry stays in the table as long as traffic flows occasionally. With PAT in overload, translations do not exist in the NAT table until the router receives traffic that requires translation. Translations have a timeout period after which they are purged from the translation table. Example 1 Static Source NATHow to translate the 1. IP address to the 1.

Hack Router Port 53 Udp' title='Hack Router Port 53 Udp' />CiscozineRemember Because the mapped address is the same for each consecutive connection with static NAT, and a persistent translation rule exists, static NAT allows hosts on the destination network to initiate traffic to a translated host if an access list exists that allows it.

CiscozineNote If a new packet arrives from yet another inside host, and it needs a NAT entry, but all the pooled IP addresses are in use, the router simply discards the packet. This can be checked enabling the debug ip nat. Feb 1. 2 1. 9 2. NAT translation failed E, dropping packet s1. The user must try again until a NAT entry times out, at which point the NAT function works for the next host that sends a packet. Essentially, the inside global pool of addresses needs to be as large as the maximum number of concurrent hosts that need to use the Internet at the same timeunless we use PAT. Remember The main difference between dynamic NAT and a range of addresses for static NAT is that static NAT allows a remote host to initiate a connection to a translated host if an access list exists that allows it, while dynamic NAT does not. You also need an equal number of mapped addresses as real addresses with static NAT. Example 3 Static PATHow to expose two different services on Internet The Web server 1. Internet outside.

Asterisk is one of the coolest pieces of open source software that I have come across. Its possibilities are endless, and its almost completely free aside from all the cool gadgets you buy to expand its functionality. The reason for this blog post is to provide a better guide for setting up asterisk to communicate with an spa 3. In this setup, I have asterisk 1. NSLU2 running unslung 6. Being that the nslu. USB ports, the super handy dandy and small form factor of the SPA 3. FXO port to interface with asterisk via ethernet and be able to make and receive calls with asterisk to the PSTN in this case to dial out and receive calls from my ooma hub. The real motivation for me to use asterisk and ooma was to save moolah. With ooma, albeit with the up front cost of 2. Our monthly bills were not as absorbitant as others, yet the reasoning behind me getting it was to get more for the same. I canceled my ATT 1. I would then still have a home phone number which I could take with me if I moved, and have super fast internet in my standards. With asterisk in the mix, I could then share out my ooma with my family and allow them to make calls to the US for free as well my sister lives in australia. Also, if I am overseas, I can make free calls to the US. I also have gizmo. DID numbers, but thats for another post. For those of you who do not know what ooma is, its a VOIP hardware solution which gives you a dedicated phone line and unlimited calling to the US, all you need is an internet connection. I got my ooma core from radio shack for 1. Ooma makes its money off the upfront cost of hardware, and also by selling its ooma premier service. This service gives you cool features, but features that asterisk allows you to do and with more customization and maybe for a little more effort. The Linksys SPA 3. FXO port that has the added functionality of routing, and it also acts as an ATA to allow your regular analog phone to connect with a VOIP provider using the FXS port If you dont have an SPA 3. Ooma hub wiring setup. The Ooma hub can be hooked up to your existing phone lines in several ways. Currently, I have my ooma phone port plugged directly into my existing home wiring jack with a splitter which also has my faxanswering machine plugged into it. This configuration allows all the phone jacks in my home to access the ooma hub without the use of the ooma scout. This is essentially the same wiring configuration as one receiving phone service from the telco. However, you lose the instant second line feature you would otherwise be provided when using the ooma scout adapter. To connect the SPA 3. Line port on the adapter to a jack in the wall, or if it is near the ooma hub, into a splitter which shares a line plugged into the Phone port on the Ooma hub or directly into the hubs phone port without a splitter. If you are on a call using a phone plugged into my wiring configuration and dial out using asterisk through the Line port on the SPA, the adapter will report a 5. If one wants to make sure the line is not busy when receivingmaking a call when using the ooma as a regular analog telephone line as well, another configuration one can use, is to hook up the ooma scout and connect it directly to the ooma hubs wall port via phone line. One would then connect a phone line from the SPA 3. Line port to the scouts wall port. This enables the scout to communicate with the ooma hub and enables the instant second line feature should the first line be active when a call out from the asterisk box takes place. Linksys SPA 3. 10. Configuration. SPA 3. Remote Management for LAN Setup. The SPA 3. 10. 2 has four interface ports in the rear, Internet, Ethernet, Phone, and Line. If you plug in a computer to the ethernet port via cable, it will provide your computer with an ip address with which you can then enter in the gateway address from an ipconfig and hit the spa. With this web gui, youll be able to configure the device. We dont want to have to plug in a cable each time to configure the device, so we will enable the web interface on the spa. Internet port with which it will receive a dhcp address handed out to it from your router currently on your network. Log into the webgui for the spa 3. Click on the admin and advanced links at the top right to get the elevated setup access Goto WAN Setup Tab Change remote management option to yes Click the submit all changes button at the bottom. Connect your spa 3. Log into your spa 3. You will find the dhcp address the spa 3. Internet port. Disconnect your computer from the ethernet port on the spa 3. Log into your 3. 10. SPA 3. 10. 2 PSTN Line Setup Now we begin the configuration of the SPA to be used with asterisk. In this setup, I will not enable Line. SPA 3. 10. 2 an ATA adapter as well allowing calls made to your voip provider to ring the analog phone connected to the PHONE port. In this setup, I just use the SPA as a gateway which allows me to make and receive calls using the LINE port on the SPA from any extension that is connected to my asterisk pbx. Keygen For Recharge Card more. Under the LINE 1 tab in the SPA, ive set Line enable to no. NOTE When things are configured properly, and the PSTN Line is registering with asterisk, the LINE LED on the SPA will light up and remain lit same with the Phone port if Line 1 is enabled. If things arent communicating correctly, the LED will not be lit I have the spa registering to asterisk. Log into the SPA web gui Click on the admin and advanced links at the top right to get the elevated setup access Click the PSTN Line tab. Where you enter in your asterisk server IP info and whether or not it will register to asterisk. Proxy and RegistrationProxy Change 1.

Register yesMake call without reg and Ans call without reg Change options to noSubscriber InformationDisplay name can be anythingUser Id can be anything but for simplicity sakes when configuring asterisk, use a name without spacesPassword  can be anything. This is where you enter dialplan information, and options to configure sending calls from asterisk to the pstn port. Dial Plans. This section of dial plans are accessed by the entire page of the SPA PSTN Line tab. There are eight DP fields because it allows you to create different dial plan options to be used throughout this tab. Voip to PSTN, and PSTN to VOIP sections both reference these dialplan fields as DP. As you can see in my screenshot, Dial Plan 2 is filled out. In my setup, this command tells the SPA that any calls answered after the PSTN to VOIP gateway option answer delay is reached, to be sent to the S extension in asterisk. You may enter any extension such as S0lt 1. IP. VOIP to PSTN Gateway SetupVOIP to PSTN gateway enable yesLine caller DP set to 1 this option references Dial Plan 1  and the default xx. This just passes anything sent from asterisk to the SPA without any changeOne Stage Dialing set to yes. If set to no, then the SPA uses 2 stage dialing, and it screws up asterisks calling out to the Line port.
