NVG589 private/public IP routing (broken NAT?)
I just was just given an Arris MVG589 router after a service call. I've paid for a public fixed IP block x.x.x.184/29, which gives me usable addresses from x.x.x.185 to x.x.x.189 with x.x.x.190 reserved for the router. I am also using the default private network at 192.168.1.0/24 with the U-verse router at the default 192.168.1.254.
The problem is that while hosts on the public Internet can reach my public address hosts reliably, and hosts on my private network can reach most hosts on the public Internet reliably, hosts on my private network mostly get timeouts trying to reach my public IP addresses on any TCP protocol (http, ssh, sftp, etc.). I can ping my public hosts from my private hosts reliably.
The other odd thing is that logs in my public hosts are showing that they're getting connections from 192.168.1.x addresses. When using my previous router, the logs in my public hosts would show connections from x.x.x.190 for any of my private hosts.
So does anybody know of some setting that could cause this that I might have overlooked?
