udp filtering

I need to forward DHCP packet from clients (Windows NT) to a server separated by two routers linked with two parallel point-to-point 64 Kbps lines.

Additional Information:

I will configure the Ethernet int. with the ip helper-address command with the

server address and the global command ip forward-protocol udp.

But this last command forwards other protocols by default that I don't need, like

TFTP, DNS, etc. I would like to filter it. How can I specify it to forward only

the DHCP packets?

Re: udp filtering

Just add "no ip forward-protocol udp xxx" where xxx is the protocol to disable the forwarding.
