Soft-Pk VPN Client through firewall

["Kalman Czibok" <czibok@cdfweb.hu>]

Dear Sirs,

Let's see the following configuration.
There is a Soft-Pk VPN box somewhere and there is a VPN client.
The connection is  working well between them. When I put the client to
behind a Debian firewall
it doesnt work. :(

  internal network - VPN (server) |------------ internet
------------------ | firewall --------- VPN client

Does anybody know which ports necessary to enable on the firewall for
the properly working?
I use ipmasqadm. Wether the autofw option necessary to use?

Very thanks,


Kalman.
