Hi, 
I have a problem with ipvs 0.8.1...
In fact packets are not "forwarded" 
here's what I can find with dmesg :
"IPVS: Incoming failed TCP checksum from 192.168.32.248 (size=40)!"
I am running 2.4.12, network card drivers eepro100 and starfire..
Following my ipvs and network conf (routing is enabled.. no firewall
rule):

ipvsadm -Ln
IP Virtual Server version 0.8.1 (size=65536)                   
Prot LocalAddress:Port Scheduler Flags                         
  -> RemoteAddress:Port             Forward Weight ActiveConn InActConn
TCP  192.168.35.199:80 wlc persistent 30

  -> 192.168.39.200:80              Masq    1      0          0    

ip a:

1: lo: <LOOPBACK,UP> mtu 16436 qdisc noqueue 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 brd 127.255.255.255 scope host lo

    inet 192.168.39.252/24 brd 192.168.39.255 scope global eth0
    inet 192.168.39.254/24 scope global secondary eth0

    link/ether 00:00:d1:ee:41:33 brd ff:ff:ff:ff:ff:ff
6: eth4: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 100
    link/ether 00:00:d1:ee:41:34 brd ff:ff:ff:ff:ff:ff
    inet 192.168.35.248/24 brd 192.168.35.255 scope global eth4
    inet 192.168.35.199/32 scope global eth4

Made test on eth4 with 192.168.35.199/32 and 192.168.35.199/24

Did I forgot something ??
PS: This works with the devel version 0.9.4..

Hervé
