iptables (v1.2.1a) -L -t mangle:
MARK    tcp  --  anywhere     10.100.1.61      tcp dpt:smtp MARK set 0x1

with using this mark:
ipvsadm -A -f 1 -s rr
ipvsadm -a -f 1 192.168.0.20:25 -m

That's all I configured concerning IPVS and netfilter. Did I forgot anything?
All other network connections seem to work.
The same box is working as a NFS and NIS server.
