My quetsion is to do with sending DHCP requests across the WAN using the IP Helper-address command.
Our networks located in Australia and our WAN circuits are MPLS provide by Telstra, the national telco. We connect to Telstra by an ethernet link so we do not have any MPLS configuration on our WAN routers.
When I configure the IP Helper-address on our remote site routers and attempt to renew or reboot a PC at the remote site we are not able to get a new IP address. Also, Ip accounting does not show any connections to the DHCP server.
If anyone knows of any MPLS restrictions concerning DHCP requests I'd be grateful if you would let me know.
