The following are steps in order to open up the ports on your modem/router combo to allow the info from the TekTalk ATA to function optimally
1. First thing is to get into your modem/router's interface.
2. Second, you want to identify the IP address the modem/router is assigning the ATA. It's usually a 192.168.X.X number.
3. Once identified, you want to locate the NAT or Virtual Server function on the modem.
4. Here it will allow you to create "rules" (essentially just a command in the modem to open up a certain port or groups of ports).
5. You will be creating 3 different rules. In each rule, it will ask you the protocol "type" you want to let pass, in this case you want both TCP and UDP to pass for all 3 rules.
6. After this it's going to ask you for 2 things: a start and finish inside port and a start/finish outside port. The important part is the inside start/finish ports. The outside ports will either fill themselves in by themselves or not fill in at all at which point they are meaningless and just leave them be.
7. The last piece of this puzzle will be to add in the IP address of the ATA found in the modem.
8 So for example your "rule" will look something like this:
IP Protocol Start/End Internal Port Start/End External Port
192.168.0.12 TCP/UDP 443/443 443/443
192.168.0.12 TCP/UDP 5004/5004 5004/5004
192.168.0.12 TCP/UDP 5060-5080/5060-5080 5060-5080/5060-5080
192.168.0.12 TCP/UDP 16384-16482/16384-16482 16384-16482/16384-16482
Like mentioned, this is an example, but a very realistic example. This is just about what your rules table will look like once completed. With the exception of the IP address, your table should look something very much like this.
Now in terms of ports that need to be opened, you need to open two single ports (443) & (5004) and two groupings of ports (5060-5080 & 16384-16482)
The static IP address that you enter MUST fall within the 192.168.0.X subnet but CANNOT be 192.168.0.0, 192.168.0.1, or 192.168.0.255.
These addresses are the Network address (.0), the SmartRG SR808N's LAN side address (.1), and the network's Broadcast address (.255).
