Re: TACACS+ problems Based on your description, it sounds like there is a block somewhere between the remote router and the server. Here is what I usually do in your situation.
1. Make sure there is no firewall or ACL blocking the TCP port used for TACACS.
2. When I do the traceroute from the router to the server and vice versa, I try to jump into each equipment as noted on the traceroute IP address result and see if there is anything blocking there
3. You can always fire up tcpdump (or Wireshark) to do packet capture on both router and server side to see how the TCP conversation looks like
