I've just upgraded from a cisco 837 to an 877. I've got a /31 range as I'm with Zen, but for some reason whilst I could nat on different ip addresses in my subnet with the 837, I can't with the 877. Here's what I get on a sh int d1:
As you can see, it's picked up the ip as a /32, and not the subnet, so I'm guessing that packets to the other ip addresses aren't getting through.
Annoyingly, I can't plug my 837 back in to re-look at the config to find any differences. Anyone got any ideas?
