Hi,
Still I could not yet reproduce the problem but I am quite sure that this has something to do with the msn&co.coms' reluctance to respond to icmp messages.
Well, after a while my office colleague did.
Actually, it took me a while to understand that my experiments on our office server and his annoyance about an "unstable" imap account had something in common :-(
The only solution we found to circumvent such small-mtu paths was: - avoid related web services OR (not so good) - Use openvpn over the path with the reduced mtu. Seems like openvpn fragments and de-fragments the packets transparently between related end2end tun0 interfaces. This even worked on his windows machine.
Perhaps this might also become an outlook-item for the next batman tunnel implementation :-)
ciao, axel
