Hello again,
I installed heartbeat an ran into some trouble. I run 2 services on the
2 real servers : httpd using LVS-NAT and sql using DR. I rely onto
hearbeat to do the NAT part, but it doesn't seem to work. I setup the
nat manually like so:
ipvsadm -A -t PUBLIC_VIP:www -s rr
ipvsadm -a -t PUBLIC_VIP:www -r 192.168.100.3:www -m -w 1
ipvsadm -a -t PUBLIC_VIP:www -r 192.168.100.4:www -m -w 1
and it worked like a charm, so no FW issues.
The listing looks pretty much the same on both instances, the problem
being that i get a connection refused when i try telnetting on 80 while
running heartbeat.

From what i understood, using heartbeat i don't get forwarded to the
real servers, instead being directed to the local (the director) services.
However, with heartbeat active, if i run the NAT manually, all is
working fine.

I appologise for this long message, but this issue is clearly out of my
league and i wanted to present all relevant information.
