Subject: [Bridge] tcp connection freezes when i dont ping the device first
Date: Fri, 08 Jul 2005 22:52:29 +0200	[thread overview]
Message-ID: <42CEE78D.2080704@endian.it> (raw)

hi

have a strange problem:
on a system with kernel 2.6.11.12 with some additional patches (fc-3 
patches and the actual netfilter patch-o-matic) i created a bridge 
containing 1 interface (eth0). (with stp enabled)
(i need this configuration with 1 inserted interface because i bridge 
together on demand the eth0 with a tap-device created by openvpn).

so far so good.. the setup does work as expected, but i always have to 
ping the device first before i can open some tcp connections to it.
without pinging the tcp connection freezes until timeout.

in a vmware-environment it's more strange. there i can't open tcp 
connections at all if i do not ping the device before.

is this normal behaviour because the bridge first has to learn the 
mac-address? i thought before tcp connections arp requests will be sent, 
too :)

ah.. the same behaviour on a system with kernel 2.4.29.

bye
peter
