[HECnet] Another thought regarding dynamic bridge setup

Just thinking aloud, Can I run a bridge between the dongle based network and my own home network? If the bridge program on my network is wrapped with a script which checks the dyndns hostname periodically against the recorded IP address, cannot I not reconfigure the bridge on my home network and restart it if required? If this is possible it keeps my configuration in a realm I've got half a chance of working out myself and saves me from hassling anyone else. Presumably at home I would need to run two bridges on different ports - with the current bridge linking back to Johnny as normal. Regards, Mark
