NAT Port Forward based on public source IP?

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

NAT Port Forward based on public source IP?

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 )

NAT Port Forward based on public source IP?

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

NAT Port Forward based on public source IP?

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.

Regards,

Smitesh
