This is driving me insanse... so any help is appreciated. The goal is to take a MPLS connected site and have it hit a Windows 2003 DHCP server on the other side of the cloud for address management. Sounds like a job for ip helper-address. Here's the config:
ip address 192.168.21.1 255.255.255.0
ip helper-address 192.168.10.201
On the DHCP server... a scope is built for the 192.168.21.0/24 network. If I do a debug ip udp I see the following:
Mar 5 11:20:50.843: UDP: rcvd src=0.0.0.0(68), dst=255.255.255.255(67), length=308
Mar 5 11:20:50.843: UDP: sent src=192.168.21.1(67), dst=192.168.10.201(67), length=308
It appears as though the forwarding is happening properly. I have verified that "ip directed-broadcast" is enabled on all interfaces between the remote site and the DHCP server. What am I doing wrong or mis-understanding here. This should work properly... right?
