This is the script that I added to the /etc/ppp/ip-up.d/ directory.

Note: this will only work for the Indiana University VPN. It does work though, most of the time.

And for some strange reason, visiting 'http://www.metafilter.com' from the N800 over the VPN immediately starts generating VPN errors, and kicks me offline. I've not noticed it with any other website. However, I can get around that by using 'SSH -D' and proxying my web connections through another machine. The important thing, is that I now get packets.

Thank you so much.
