Can you be a little more explicit?  I'm such an iptables idiot I don't know 
what that means.

Here's what I have that I'm told should work:

[root at radium root]# /etc/init.d/iptables status
Table: filter
Chain INPUT (policy ACCEPT)
target     prot opt source               destination

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination
Table: nat
Chain PREROUTING (policy ACCEPT)
target     prot opt source               destination
DNAT       tcp  --  anywhere             anywhere           tcp dpt:2402 
to:10.0.26.52:2401

Chain POSTROUTING (policy ACCEPT)
target     prot opt source               destination
MASQUERADE  all  --  anywhere             anywhere

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination
[root at radium root]#

Thanks,

Michael
