Problem is, I’d like to stay connected to the UCT network as well so that I don’t use up my precious* data bundle for UCT services, and this requires a bit of custom routing magic. So I have a script:

#!/bin/sh
GATEWAY=137.158.32.97
route add -net 137.158.0.0/16 gw $GATEWAY
route add -net 192.48.253.0/24 gw $GATEWAY
route del default
route add default ppp0

137.158.0.0/16 and 192.48.253.0/24 are the UCT netblocks, and 137.158.32.97 is the router on the subnet that I’m mostly using at the moment. ppp0 is, of course, the name of the interface associated with the HSDPA connection.

The problems with this script currently are that I have to edit it to change the gateway for each subnet that I’m on, that I have to run it manually each time I connect, and that it doesn’t restore the original routing when I disconnect. The first and third problems should be reasonably easy to solve, but the second will probably require that I dig into the mysterious world of NetworkManager. (Cue dramatic music.)
