I remember an historical problem with certain routers that would not allow certain packet sizes through, it may have been to do with PPPOE which adds extra bytes of overhead to a packet (or something like that) and was fixable by reducing the mtu on the eth port. So your problem may be unrelated, but I have seen a similar problem and thats how it was fixed. Try reducing the MTU on your ethernet card. _______________________________________________ Linux-users mailing list [email protected] http://lists.canterbury.ac.nz/mailman/listinfo/linux-users
