There are three parts to getting a DHCP address working in a router:
1. Router's IP Address
2. Router's Netmask
3. The Gateway address (where the router sends non-local packets)
Once these are set properly, there is no difference between a manual
setting and a DHCP setting.
It sounds like the DHCP is setting the wrong Gateway address. Check that
all three are correct when using DHCP.
