I have an issue with connectivity between a main office and one of my branch offices. I can ping the serial interfaces of the Branch B router, and ping a PC on the Ethernet, but from the Branch B side I cannot ping the ethernet on the host router or any ethernet address on the host side. Here is the scenario. Branch A is an existing office and connectivity is fine. I'm trying to bring online Branch B. The host site has a Cisco 1841 Router running 12(3) IOS with two WIC1-T1 cards in it. Branch B has a Cisco 1720 with a single WIC1-T1 card in it.
