I'd agree - normally it is only necessary to set the interface
address, bitmask and default gateway within TCPIP$CONFIG and the
routes that Richard lists will be set up when TCPIP starts:

- 127.0.0.1 is the loopback address which all IP stacks should
configure automagically (and with a Host route);
- the network that the VMS box is on will use the VMS box's own IP
address as the gateway (Network route).
- the VMS box will use itself as the route to itself (Host route) and
- everybody else is on the default gateway/quad zero/gateway of last
resort route (Network route)

You can insert static routes if necessary, but they're usually needed
where you have multiple routers to multiple destinations (e.g.
192.168.2.0 goes out via a leased line to a secondary site whereas
everything else routes through 192.168.1.1

FWIW, I've used Speedtouch and Netgear routers at home on my ADSL line
with no problems, except when I got a lightning strike that fried the
phone, the Speedtouch, the network card in the Alpha, the 10 Base T/
AUI hub and the Pentium PC that I was using as a Freesco router.  Oh,
and the ethernet port on my laser printer.  The thing that would have
cost the most to replace was the ethernet card in the printer.  Go
figure.
