Ben,
thanks for fast reply, but unfortunately this does not help. Interesting
that now ping in guest "works" forever, which means it's not complaining
about host down, but also loses 100% packets. What I see in tcpdump on
host are good packets from server side qemu, but wrong (TCP checksum
invalid) packets from the client side qemu.
E.g.
00:41:12.470887 IP (tos 0x0, ttl 64, id 42317, offset 0, flags [DF],
length: 56) localhost.localdomain.32960 > localhost.localdomain.11234: P
[bad tcp cksum fe2c (->b649)!] 2448:2452(4) ack 2449 win 8192
<nop,nop,timestamp 4101291 4101048>
00:41:12.510409 IP (tos 0x0, ttl 64, id 10538, offset 0, flags [DF],
length: 52) localhost.localdomain.11234 > localhost.localdomain.32960: .
[tcp sum ok] ack 2452 win 8192 <nop,nop,timestamp 4101301 4101291>
Is there anything other I might try to better debug this issue?
Thanks a lot!

Karel,
Try:
qemu -hda openbsd-fw1.img -net nic,macaddr=22:33:77:55:66:00 -net
socket,listen=127.0.0.1:11234
qemu -hda openbsd-fw2.img -net nic,macaddr=11:22:33:44:55:66 -net
socket,connect=127.0.0.1:11234

Hello,
I'm trying to get qemu 0.8.0 working with two instances and VLAN between
them. I'm using socket connections and options like:
qemu -hda openbsd-fw1.img -net nic,macaddr=22:33:77:55:66:00 -net
socket,listen=:11234
qemu -hda openbsd-fw2.img -net nic,macaddr=11:22:33:44:55:66 -net
socket,connect=silence:11234
once both OpenBSDs are started, I'm trying to ping from one to another,
but it's not working. When using tcpdump on the host system I see some
packets exchanged, but then suddenly after few packates (4-7) it stops
(in tcpdump) and ping in guest complains about host down. Note that ping
in guest lost 100% of packets.
Qemu is compiled with GCC 3.4 on Debian Sarge on AMD64 (64bit).
Any idea what to do to better debug this issue?
Thanks,
Karel
