Hello,
I have one public IP address but multiple local servers that run on the same port. I cannot change the port the clients use to connect to this server, so I can't do a port map in my NAT router. The solution I had in mind, is to filter on source address. If a client from public IP X.X.X.X connects to port Z, I want it to go to internal server 10.10.10.10 and if a client from public IP Y.Y.Y.Y connects to port Z, I want it to go to internal server 10.20.20.20. Is this possible?
Thanks,
Ruud van Strijp

Hi Ruud,
Are you planning to do this on Firewall or Router ?
I'm not too sure about this on Cisco Routers, but I think I have seen something like this on Cisco's cheif compititor (just that I don't want to take the name of the vendor )

Thanks for your replies. I am trying to do this with an ASA5510 or ASA5505. Would that be possible?

Hi Rudd,
On Firewall it should work (although, I'm not good at firewall); but I'm saying this because of the fact that firewall keep session information (though now a days higher end router also do same) also.
I suggest to post thiss query in Firewall under Security forums.
