Hello Joe,
I configured the servers following the mini-HOWTO.

When connecting to http://87.98.225.39 and running tcpdump -i any port
80 -p -n -t I see it is receiving connections.

ipvsadm detects that connection too:

Servers can ping each other.
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
I don't know where my error is, don't know where else to look.
Any ideas?
Thanks,
Antoni

there's no demon listening on the port on the machine that's
receiving the connection request.

the packets aren't being returned.
at this stage I suggest you setup using the scripts exactly
as is in the mini-HOWTO.
