Compression over VPN

[phyrtech]

I have successfully installed poptop on my linux box at home. I can successfully connect to the vpn and map network drives, etc. Of course, running vpn across 2 crippled cable lines (40KB max TX on both lines) makes for rather slow vpn. I then noticed that there is 0% compression. I checked the messages log and see this for one of the transactions:

It says 128-bit stateless compression is enabled yet there is a 0% compression on the line.

I am running poptop on the latest release of Ubuntu and am connecting in with a Windows XP Pro machine using all the default settings.

How can I get the compression working at a reasonable level?

Thanks in advance for any help.
