I recently reinstalled my server from Debian Lenny to Squeeze and ever since the reinstall I'm unable to establish a PPTP connection to a remote site. The remote site is running Windows RRAS PPTP server. The PPTP connection worked from Lenny and works from a Windows client. It doesn't work from the Debian Squeeze server. The config files for PPTP and connection were simply copied over from the old system. The connection establishes and then just disconnects right away.

From syslog:

What is the problem and how can I solve it?

The problem existed because TSS MSS clamper on the router was disabled on a PPPoE connection.
