I am trying to tie two networks together via VPN over two T1's. This has not been implemented yet and want to see if there is something I am missing/overlooking in my design. Just curious if anyone can analyze it and tell me I am a complete idiot or genious.
The basics of it is that I have a server sitting in the company HQ that hosts the POS system, Domain Controller and Exchange server. I have another point two cities over that need to use the POS System and Domain controller. I plan on using Cisco 1721 Routers to establish an L2TP VPN Connection between the two sites. Our shipping and receiving department, and a few company directors are moving to the Lynnwood branch, so this solution needs to work 24/7/365.
My concerns are the reliability of L2TP VPN being used 24/7, and proper configuration of the Cisco routers. I have a 1721 in the mail for me to play with before this whole thing gets implemented.

Thanks for your help in advance!
