I assume you are not able to ping the other way around either when the network goes down, i e from gamma to fritzbox? Are you able to ping mercury from gamma? (But as I interpret your map they are not on the same network i/f on gamma so that might not provide much useful info.) What happens if you do ifconfig re1 down / ifconfig re1 up on gamma when the fault have occured? Or if you unplug and then put the network cable back again? In other words, how do you usually recover from the problem? Are there any clues in /var/log/messages that might be of interest? Also, the usual first question on this list is: can you provide a full dmesg from gamma? It is almost always more helpful than people think, so never leave home without it! :-) Regards, /Benny
