I have to send a 1750 router to a new branch, so we can use peer VPN networking. This one is different for me -- the ISP router has an inside (my side) address of 10.100.18.1. It's expecting me to be10.100.18.6. The devices on the network are 10.100.18.0 (128 mask -- the other half of the C net is for VOIP).
I'm a generalist here, and am not overly familiar with all the capabilities of IOS. When I try to give the two ports addresses like10.100.18.6 and 10.100.18.7, the router complains that they overlap.
If someone would be willing to point me in the right direction, I'd appreciate it.
