Unfortunately its web portal is all in Japanese, but chrome translate came in handy.
This my current setup:
internet -> telstra cable modem -> [wan port of] WRT54GL [lan port] -> [lan port of] RT57i [voip port 1] -> telephone
The WRT54GL has IP 192.168.1.1, DHCP enabled
The RT57i has IP 192.168.1.2, DHCP disabled
I can plug my PC into a LAN port on the RT57i and connect it to internet using the 192.168.1.1 router no worries.
I will post the results of a telnet "show config" command in the next post.
The router reports that the SIP server isn't responding. Can anyone help me figure out whats going on, and whether its possible to get this router to work with 2talk?
