[Sean Clarke]

Ok I have a problem and I dont know what is happening...

here is the scenario

Windows 2K behind an linux ipchains box  poptop is running on this same
machine with the cable modem of course. exernal ip 24.66.168.51

Windows 2K box internal ip address....  I have setup the VPN Connection on
the windows2k box.  

On my linux box (poptop server) I have this in my logs
