I have two 2501s each with IOS 12.2 and 16MB. They are linked with a DTE/DCE serail cable. One is linked to our T-1 and the other to our LAN. When going through the routers to the net, I get about 60k throughput. If I bypass the Ciscos, I get about 866k throughput. This is much too dramatic of a diff for my tastes.
Here is the output of `show run' for each router. The routers are simply named (obviously) WAN and LAN.

I found that I had to run NAT on both routers to get a link. If there is a way to streamline these configs, I would appreciate it. I have also tinkered with the bandwidth settings up and down, currently at 1000 and it does not seem to have any effect. While I am at it, I'll say right now that I am a true newbie to Cisco IOS, but have been doing the best I can using Cisco's site and some books.
If I am posting in the wrong forum please point me to the correct one. Also apologies for the long post.
