Well, where is xl0 and fxp0 connected to? My first bet would be a standard switch, if so try setting both devices to the same MAC address. Otherwise the peers you connect to will send the IP packets to the wrong MAC address and only after a timeout (or a forced push thanks to the ping) will get their ARP cache into shape. Regards, Uli
