Thanks Malcolm for the response. That is how it is setup, the real server is the same as the director node for one of the nodes. Even if connecting to only the primary node while all others are offline it does not work.
I noticed that if I use xinetd forwarding it works, but that's not what I want to use. I wonder why iptables wouldn't be able to work, if there is a method using iptables that'd be great.
