Funny thing is that the problem persist. Tonight I've made some tests
with 782M. I've connected two computers in my office (win7 and linux)
through this pair directly. I seccessfully tested ping both
directions, then switched them so that each crossed the bridge and
was unable to ping.
When you switch then, do the Linux and Windows systems know that their
network cable has been unplugged?
If they do, they will very likely flush their caches.
If the problem persists after the Linux and Windows systems flush their
cache, I'm strongly thinking that the problem is with the DSL bridges.
Regarding this I can surely tell (this is all about 782M pair) that
after box crossing the bridge MAC-port table is not updating (how it
should be if it were switch's logic). Packets with srcMAC of crossed
box CAN cross the bridge, but with dstMAC of crossed box CANNOT cross
the bridge.
That really sounds like the something is not forwarding traffic b/c it
still thinks that the destination MAC is on the local side.
Please clarify, when you ran your test, did you try trading sides of the
Linux bridge individually or the Linux bridge in combination with the
DSL bridge?
Can you try repeating your test on either side of the Linux bridge?
