All services running on router SLE= S=20 are ok. I install virtual network. I install Debian guest on KVM, connect it to virtual network. SLES is=20 router to the internet for Debian. [APP server]--physical 10.29.2.0/24--[[SLES10 on KVM]--virtual=20 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=20 can't. When I try to use TCP conenction from [Debian] to [APP server]=20 (ie. ssh) connection can't establish. Tcpdump shows, that packets from Debian goes to APP. No response go bac= k=20 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 ? --=20 Lubom=EDr Vogl
