Title: PPTP VPN enable compression?
Post by: jameswilson on May 11, 2010, 02:29:20 AM

Everything is working fine, but i dont get any compression reported from windows xp. I use this to keep our mobile data use down as low as poss. All the info i can find seems to old, or refered to upgrading a package which seems like a bad idea. Is this something that we cant do?

According to this page (http://mppe-mppc.alphacron.de/) you will explicitly have to specify this on the client:

By default pppd tries to negotiate MPPC and don't negotiate MPPE but will agree if peer wants encryption.

Correct - MPPC is patented, and Red Hat doesn't have a patent license, and isn't prepared to challenge the vallidity of the patent.
