This may have nothing to do with FreeBSD, but maybe someone will have a suggestion:
We have servers A, B and C connected to three different ISPs on 3 continents. As of few days ago A and C cannot talk to each other (the routing problem is upstream of all end-point ISPs so who knows when will it be solved.) B can talk to both A and C. The 'obvious' idea is to use B as relay and source-route traffic between A and C to go via B. However, no amount of static routing, firewall allow-ing, sysctl-ing would do the trick. The packet would never even leave from A or C for the other side. Is there some other barrier to the source routing that has not been taken care of? I know that this can be taken care of with ssh tunnelling for each specific application/protocol, but the networks are more complex than abstracted here. In short, this was attempted: A: route add C B sysctl net.inet.ip.sourceroute=1 sysctl net.inet.ip.accept_sourceroute=1 B: rc.conf: gateway_enable="YES" sysctl net.inet.ip.sourceroute=1 sysctl net.inet.ip.accept_sourceroute=1 ipfw add pass ip from A to B ipfw add pass ip from B to A C: route add A B sysctl net.inet.ip.sourceroute=1 sysctl net.inet.ip.accept_sourceroute=1 . end .
