Currently i've ADSL from Online ADSL in the Netherlands. This Speedtouch modem is fairly protected. The only way I can add a proto 41 forward for my Airport (which manages the tunnel) is via Telnet. The problem is that this is only a temporary one. When the modem resets this entry is gone. I can make a script which uses telnet and readds the nat entry but this means i get the tunnel downtime in the config panel. Plus I turn my internet off when I am away, so what would be the best setup with the Airport?
