Hi, I have inherited a system which I am trying to make work. It consists of two routers each with an ethernet and a bri. For some reason this very straightforward network has some NAT. I guess the NAT was configured as a workaround for some old legacy application and migration to a new network or something.
My problem is that the routers dial and ping each other OK without the NAT (removing 'ip nat outside' from dialer 2) but when this is put back on the traffic doesn't pass. Does the NAT pool address range need to match that of the bri at the receiving end? Am I missing some static routes for the pool address?
Router configs summerised with the interesting bits only!
Router1. (Dialing end)
ip address 192.168.202.191/24
ip nat inside
ip address 188.8.131.52/24
ip nat outside
ip nat pool NATPOOL 192.168.0.112 192.168.0.112 netmask 255.255.255.0
ip nat inside source list 101 pool NATPOOL overload
ip route 184.108.40.206 255.255.255.0 dialer 2
access-list 101 permit ip any any
Router 2 (Receiving end)
ip address 220.127.116.11 /24
ip address 18.104.22.168/24
ip route 0.0.0.0 0.0.0.0 bri0
ip route 22.214.171.124 255.255.255.0 bri0 - not sure why this route is here.
