I don't think it's the linux boxen's fault. Why don't you compare
traceroute's and see if you hit any of the same equipment on the way. If
you do then that's most likely the device at fault. You should then both
pressure your ISP's to fix the problem as it is afterall an inter-net
service provision problem.
Another way to temporarily get around it is to find a 3rd party you both
can reach and get them to add a couple of static routes. You then add a
route to each other using this 3rd party as a gateway. Alternately you may
also have a slim chance of success using each other's ISP's routers as
gateways. Experiment with nodes that show up in the normal traceroute.
