I am not sure what I am doing wrong but for the life of me I have tried everything. The equipment is 2x Cisco 10k hooked togther currently with 8 T1's put into a multilink for traffic. My interfaces are private ip's in the 10.100.16.x range. I am using OSPF for the routing but that shouldnt matter here. We have upwards of 50-70 computers on this link that are working without issue. But I lost the ablility to get to all my equipment from my computer at the main office.
