Hi Michael.

I do not know if you've read the Linux as a VPN Client to FireWall-1
howto. Because there are some things you have to set up on the
checkpoint as well. You can find it here:

 http://www.freeswan.ca/code/old/freeswan-1.8/doc/interop.html

I don't know ho your administrator did. But you have to use a shared
secret between your client and the checkpoint and you have to make sure
that the checkpoint uses 3des and md5 for the connection. But most of
the topic is included in the pdf document.

I've read that you probably could make it work with the x509 patch, but
i have never tried it.

Good luck

Cheers
