[Openswan Users] Connecting to Checkpoint VPN-1

[Eugene Kotlyarov]

Hi

I wonder if anyone actually successfully connected to Checkpoint VPN-1?

I used this instructions, for configuration

http://www.fw-1.de/aerasec/ng/vpn-freeswan/CP-FW1-NG+Linux-FreeSWAN-Gateway.html

but they are quite outdated and didn't work for me anyway.
Should openswan work with Checkpoint or are they using some kind of 
proprietary protocol?
