Broadcast forwarding.

Can anyone assist me in getting udp broadcast forwarding working from a central 3745 out to remote routed networks connected via ISDN using 1721's????

Re: Broadcast forwarding.

You can use the following commands to specify the port number you want to be forwarded and where to forward them:

ip forward-protocol udp ; specifies what ports should be forwarded

ip helper-address ; specifies where to forward them.

Also, for ISDN links, use 'broadcast' keyword in your dialer maps to let broadcast traverse the ISDN link.

Hope this helps.
