What is open VPNC:
VPNC is an open-source VPN client for Linux and other Unix systems which is compatible with the OUCS VPN Service and which offers some advantages over the ‘official’ Cisco VPN client for Linux
So VPNC will connect to Cisco VPN gateways. But will it connect to Checkpoint's or Nortel's gateways as well?
then please advice if there are some other tools like OPEN VPNC that can service checkpoint or Nortel VPNs ?
