Greetings. Is there a commonly known cause of *return* TCP/IP traffic to reach but be dropped rather than passed back across a bridge (ala bridgename.bridge0) but... get this... only on the first try?
I'd like to get into a detailed explanation of the network topology I'm working with here but I don't want to scare off anyone by opening with a 3 page email. The bridge seems to work fine for everything except every 24 hours or so (may be less... like say 2-8 hours actually?) individual clients trying to access services on a *certain* cluster of servers on the other side of the bridge has to either first ping the server (which always works) or else just accept that their first connection attempt WILL time out but the second one WILL succeed. Obvious issues like the server machines or even just their network devices going to sleep because of misconfigured power management has already been excluded as a possiblity because tcpdumping on both devices in the bridge clearly shows missing return traffic only being passed back to the other device AFTER the first attempt. Anyway, any advice is greatly appreciated. thanks, ~jon
