Following situation: Host A has two ethernets and a 24 hour connection to the Internet. It uses natd/ipfirewall/ipdivert to masq/firewall. The IP number on the public side is static. Then there are several other hosts, all have 1 ethernet and 1 modem and are also running natd/ipfirewall/ipdivert and use pppd to dialup to a provider, using dynamic IPs. So far, so good, everything works fine. Now I need to connect the offsite hosts via an ip tunnel to the main location. The offsite has to start the tunnel, as it has a dynamic address on the public. I tried several things with ppp, iptunnel (2 different ones) and ssh, but all are not stable nor user friendly. Has anyone come up with something simular ? Any pointers ?
