I'm trying to get a 2830N up and running in a Regus hosted office in the UK. This means that I have to connect through Regus' ethernet to get internet. This works fine with either PC in the office, directly connected to the floor point. However, if I connect the router through the WAN2 port, with Regus' IP settings or setup to automatically get an IP address via DHCP, I get nothing. I suspected that it could be a DHCP lease issue, but neither PC is suffering from not being able to connect. I'm kind of reaching the end of my tether so I'd really appreciate any advice.

Thanks in advance!
