I understand, but it's quite common to filter out non TCP/UDP/ICMP

There's a simpler way of doing this : 'make install POPTOP_USE_MPPE=yes'
in net/poptop. Then poptop is ./configure'd with the correct path to pppd.
Anyway, that's not the source of your problem. The first thing to do is
removing the 'require-chap' line of your pppd config. I'm not sure if it
is possible to negociate Microsoft's encryption when not using Microsoft's
own "tweaks" of CHAP. It it still doesn't work, try without encryption,
using PAP, using either version of CHAP-MS and so. Thus it'll be easier to
tell where the problem lies.
And I thought I had ran through all PoPToP issues this summer :o)
That's how I did it, Anton. I never saved anything
for the swim back.
