UDP Broadcasts via 2621.....

[itd17]

I'm having the worst time trying to get this to work....

One building w/a separate subnet and a 2621 needs to forward DHCP requests to another building/subnet that has a 2500 connected via frame relay. I have the 'ip helper-address' command located on the ethernet side of the 2621, but I see no DHCP activity. Anything I'm missing???

Thanks,

DHCP is UDP in both directions.. so you need to have it enabled on BOTH sides.. not just one. I would also suggest using a directed broadcast instead of a single ip address.. ie.. instead of forwarding broadcasts to 192.168.1.1/24, you would forward to 192.168.1.255/24.
