No, the connection never makes it to the real server.
I have no idea why. I set everything up according to
documentation.

Yes, it does now anyway. I made a small change to the
host which the uml is running on. Simply had to
change the default gw to correct device (i.e
uml-bridge).

I am not sure. What would the best way to check be ?
It appears that I am unable to connect to the Real
servers. It might be a routing problem, although all
the realservers can ping the DIP, and vice versa.
here is the routing tables for my Director (uml),
RealServers, Uml-Host
Director:
#####################################################3

UML-Host:

0.0.0.0 192.168.10.1 0.0.0.0 UG
0 0 0 uml-bridge
BTW: it appears the the load-balancing functionality
does work. I tried making 2 connectings to the VIP
(port 80),
and "IsActConn" had a "1" in each row, i.e. for each
of my real servers (2 of them).
If only the connection would make it there. Would
this be caused by incorrect routing on the director,
or the real server?
