We have a small remote location a block away from our main building connected via bridged T1. Here's the flow:
Main Building >> 2801 >> T1 << 2801 << Remote Building
This is currently operating as a bridged connection between the two locations. We are having a problem with DHCP requests not working at the Remote Building as well as specific UDP(port 7700) traffic. I tried working with ip-forward protocol commands but that didn't appear to help.
Is there any solution available to help in this situation - allow DHCP traffic and UDP traffic to flow between locations?
