Hello Joe,
I configured the servers following the mini-HOWTO.
Linux Director:
IP: 91.121.30.157
VIP: 87.98.225.39
IPVS Configuration:
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP 87-98-225-39.ovh.net:http wlc
-> ks35593.kimsufi.com:http Route 1 0 0
-> ns24396.ovh.net:http Route 1 0 0
netstat -rn output:

Destination Gateway Genmask Flags MSS Window irtt Iface
87.98.225.39 0.0.0.0 255.255.255.255 UH 0 0 0 eth0

When connecting to http://87.98.225.39 and running tcpdump -i any port
80 -p -n -t I see it is receiving connections.
I assume this tcpdump is running on the director.
IP 87.223.248.211.3243 > 87.98.225.39.80: S 519437827:519437827(0) win 65535
<mss 1460,nop,nop,sackOK>
I assume 87.223.248.211 is your client.
ipvsadm detects that connection too:
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP 87-98-225-39.ovh.net:http wlc
-> ks35593.kimsufi.com:http Route 1 0 1
^
InActConn entry==1 likely indicates no route from realserver
to client. Is the realserver's default gw NOT on the
director and IS a route to the client?
Kernel IP routing table

0.0.0.0 213.186.39.254 0.0.0.0 UG 0 0 0 eth0
does 213.186.39.254 have a route to the client?
can you ping the client from the realserver(s), can you ping
the VIP from the client, can you ping the RIP from the
director?
tcpdump -i any port 80 -p -n -t returns nothing
Connecting from a client I get:
telnet 87.98.225.39 80
Trying 87.98.225.39...
telnet: Unable to connect to remote host: No route to host
hmm. I would have expected a timeout with the above
symptoms.
