Hi, guys! If you want, take a look at http://www.ucb.crimea.ua/~ru/FreeBSD/iptunnel This program uses divert sockets and tunnels IP thru UDP. You can tunnel a whole network, a single host, and it can be done based on any firewall rule (e.g. on any combination of src/dst hosts). I've written this program to build a distributed Intranet network in our organization. We have four departments, each attached to some ISP, and we use only four real IP addresses to communicate with each other. And we use one logical intranet network. In the meantime, I'm planning to implement a crypto-feature. Let me know if you have a questions about how it works. Your feedback would be appreciated too. At the moment of writing there are 94 fetches of my program since Dec 13, 1997. Please use subject: IPTUNNEL if you have a questions about this program.
