I have a ip500 (r4.058407)and a ipo403 (r3.2.55) I am trying to network them together on the same network but everytime I plug in the 403 it causes the ip500 to lock up and restart. Here is my set up the ip500 is 192.168.1.181, the ip route is ip address 192.168.1.0, mask 255.255.255.0, destination lan 1. The ip line is set up like this line number 99, incoming /outgoing 99, 8 channels, gateway address 192.168.1.182, faststart,direct media path, and voice networking are checked. Here is my set up the ipo403 is 192.168.1.182, the ip route is ip address 192.168.1.0, mask 255.255.255.0, destination lan 1. The ip line is set up like this line number 99, incoming /outgoing 99, 8 channels, gateway address 192.168.1.181, faststart,direct media path, and voice networking are checked. If anyone has any help that would be great.
