That could be a primary IP address on an interface on which your 76 address is a sub interface. The interface will do proxy-arp when a traffic request comes in. Or something else! I'm not sure if this will work, but you could actually hard code your default gateway with a -hopcount 2 (or higher) and see if that works. I've not tried it on a live machine. Something like route add default 151.164.184.xxx -hopcount 5. You may have to delete the DHCP-assigned entry first. Regards, Mike
