why bring it up, if you're not going to use it?

huh?
I could understand something like...
statement 1:
ifconfig tr0 147.110.49.17 \
netmask 255.255.255.252 \
broadcast 147.110.49.19 \
mtu 1492 up
statement 2:
route add default gw 147.110.49.18
THINK:
Net 147.110.49.16 <-- we are here
L390 147.110.49.17 <-- this is me
OTHER 147.110.49.18 <-- this way to the rest of the world
bcast 147.110.49.19 <-- both of us
I don't know what 172.20.15 85 is meant to be, but there's no way
anything in 147.110.49.16/30 is going to know how to get there if
the OTHER guy at 147.110.49.18 doesn't know the way.
> I get the following error "gw: Hostname lookup failure".
small wonder, this box has no WORKING default route
for the name-service to resolve from.
I ASSuME that /etc/resolv.conf says something like
domain blah.com
server 10.10.10.10
and that resolv just can't get an answer from 10.10.10.10

OK, then the hardware works on both sides, now all you have to do
is configure it.
ifconfig the tr0 up, set the default route to whoever is on the OTHER side
of the tr0 (there's only 1 other address there, so it can't be that
difficult).
There is only ever 1 default route (that's what 'default' means).
If it works after statement-2 above, you're OK,
else fix the OTHER box at 147.110.49.18.
