Thanks Ciaron and Nigel, I removed the route statements network 192.168.200.0 and network 192.168.1.0
from the 2611 and 3640 respectively, without any effect on the route tables. Apparently, the eigrp process informs the routers of the connected networks on the far sides of each other, making the network statements unnecessary. I posted the most relevant parts of the configs, assuming it will be obvious that my ppp config is ok, since I can dialin to the 3640. The 3640 is a production NAS connecting users b4 with a global IP pool. I would have configured NAT on the 2611 Internet gateway, but even that has rfc1918 address on the serial link to the Internet. What I did was configure NAT on the 3640, making the LoO the inside and E0/0 the outside. But even that is not working, with traffic both ways ending at Lo0. If I can get a dialin user on the async line to ping e0/0 of the 3640, then the issue should be resolved.
