Subject: SLES 10 - routing tcp network problem
Date: Fri, 22 Mar 2013 10:06:17 +0100	[thread overview]
Message-ID: <514C1F09.3030909@vogl.cz> (raw)

Hi,

I try running SLES 10 router on KVM. All services running on router SLES 
are ok.
I install virtual network.
I install Debian guest on KVM, connect it to virtual network. SLES is 
router to the internet for Debian.

[APP server]--physical 10.29.2.0/24--[[SLES10 on KVM]--virtual 
10.29.7.0/24--[Debian on KVM]]

SLES and Debian is on the same KVM host.

I configure routing and use ping to test it. All ICMP working, but TCP 
can't. When I try to use TCP conenction from [Debian] to [APP server] 
(ie. ssh) connection can't establish.
Tcpdump shows, that packets from Debian goes to APP. No response go back 
to Debian. Log of ssh shows, that no connection establish.

I replace SLES10 by another debian

internet--Debian--Debian

TCP and all other comm working.

I use passthru config of NIC (macvtap).
QEMU emulator version 1.1.2 (Debian 1.1.2+dfsg-5)
SLES 10 SP4

Why tcp through SLES10 doesn't work ?
Can you help me ?
