Yes, I've tried this before, and I've just tried it again and it
doesn't work. It shows the same behaviour as when I set a fixed
address in the DHCP server - I can ping the DHCP server but not the
gateway.

I setup the TCPIP address of the machine and added a default route to
the gateway. Previous, before I installed decnet, this configuration
worked fine.
