If you are dialed into that ISPs dialup and get a relay denied, then they
haven't correctly set up the list of IPs that are allowed to relay.  They
need to fix that.  You *MAY* be able to work around it by authenticating
with their POP server before making the SMTP connection, but they should
still allow relaying...

If the tech you are speaking to isn't able to resolve the fact that you
get a relay denied message, then he obviously needs to contact their
next level of tech support.

Why are you putting a netmask on your default route?  You probably
don't want to do that, but I don't know if that's causing your
apparent problems.

You did use a different IP address, or disconnect your girlfriend's machine
when setting up your own?  Also realize that if you are taking her IP,
you will have to wait for the ARP cache on the router to time out, or
force sending your own gratuitous ARP packet before it will recognise
you.  This may be on the order of 5 minutes you have to wait.

You will need a route entry for the local network that your IP and the
remote router is on (that's where you want the netmask -- make sure the
broadcast address is correct too, or you won't get the proper ARPs).
Then you need a default route.

You'd have to set up your Linux machine to masquerade the 192.168 addresses,
and the boxes on that net would use the 192.168 address of the Linux
machine as the gateway.

I've heard they periodicly scan your machine looking for services running,
and if you have them enabled they will drop you.  I don't know why they
wouldn't just block that sort of incoming connections...  If you wanted
to host services, you probably should have gotten DSL instead (if you
could).
