i need establish a first tunnel connecting a linux vpn server to a bewan 6104 which connect my intranet to internet. then a second tunnel starting from the bewan (NAT) to ISA operating as firewall in front of my INTRANET. Clients of my LAN must connect to servers behind the linux operating in front of a PIX. No problem to connect the bewan to the LINUX But don't know really how the operate on the whole network Is there some help somewhere ? thanks
