rdr to internal servers doesnt work with load balancing

[Max Gribov]

Hello all,
is it possible to load balance two lines, but have 1 specific port 
redirected into internal network from only one of those lines?
Especially when that line's next hop upstream is not the default gw for 
the machine?
I know i can do this on the line which is also used as default gw, but 
doesnt seem like i can the other way around.
I spent several hours using different no nat, route-to, reply-to 
combinations, but it just doesnt work.

I appreciate any feedback on this...
