1:1 NAT probably wont work well unless you have 4 external IPs. (1 for each 
server you wish to use)

set up ServerNAT entries in monowall, and use the Inbound NAT to redirect the 
ports you want, to the servers you want. Allow it to auto-allocate the rules. 

thats how I've done it anyway - although I have multiple external IPs, and I 
still prefer to use InboundNAT over 1:1 NAT purely for the flexibility (and 
correct me if I'm wrong, but it makes the firewall rules+NAT rule a bit more 

1:1 NAT only makes sense to me if you really need the internal/protected 
server to think it really is on the internet. Most of the time, I think this 
is not the case people want. 

and posting the same question twice in two days wont win you too many friends 
on any mailing list I'm aware of..
