I am using SKIP to tunnel between two RFC1918 networks that are behind FreeBSD firewalls. The only problem I found, and it may not be a problem for everyone, was that SKIP packets were being sent with the source address of the internal, behind the firewall, RFC1918 host. I modified the code to use the interface address the packet is being sent from for the packet source address. http://skip.incog.com/source.html John Capo Embedded Hardware/Software Design IRBS Engineering Unix/Internet Consulting - ISP Solutions
