[c-nsp] NAT with 2 routers

[james edwards]

I am working with a client who is trying to NAT with 2 routers where
in nat outside interface is on one router and the inside nat IP's/hosts
are located off the second router. There is a T-1 between the 2 routers.
I think I need to bridge the T-1's, making the 2 routers on the same LAN
(no need for the static routes) but I only have remote access and can't
try any commands that might lock me out. They are needing to one to one
NAT the radmin port, 4899 to host 10.166.65.50. Here is the config they
have so far, could someone give me some hints ? Am I correct in thinking
NAT's public and private interfaces must be on the same router ?
