static IP assignment question

[tritch]

A quick Google search indicates your router lacks the ability to assign static IP's using the OEM firmware. Unless you are willing to try dd-wrt or Tomato firmware you are limited to only one option below.

I'm assuming you have admin access to the WAN settings in your ATA....

Log into your ATA and turn off DHCP on the WAN port of the ATA and select static IP instead. Assign the same subnet and gateway settings for your network and make sure you assign a static IP address outside of your router's DHCP IP pool range.

Example:
Your router's DHCP address pool range is 192.168.1.100 to 192.168.1.150 with a subnet mask of 255.255.255.0 and a gateway of 192.168.1.1

On the ATA, turn off DHCP to the WAN port and apply a static IP like this:

192.168.1.151 (IP outside your router's pool)
255.255.255.0 (subnet mask)
192.168.1.1 (gateway)

Then log into your router and forward the UDP port range to this static IP.
