How to Forward / Redirect Destination IP

compucoder

Hi everyone,

I have a puzzling dilemma and can't figure it out. We have a developer who is using a remote client WSDL file and that file is written so it works on the client subnet. It basically has 10.0.0.0 addresses it uses for hitting their servers. What I am trying to do is if the firewall sees a outbound connection from the developer trying to hit a 10.0.0.x IP address to forward it to the clients public IP address. I guess I am trying to do the opposite of port forwarding.

I think I want a redirect rule but don't know how to do this in PFSense. So something like this:

LAN->10.0.0.x Redirect or forward so it looks like this LAN->69.x.x.x (client public IP)

Thanks for any help.

It might be possible to do something with virtual IP addresses so that it will allow you to select those addresses as the external address on a LAN port forward.

Not quite the answer your looking for, but your developer should be able to just change the address in the WSDL or in his connection code to point to the proper IP. Much easier than trying to do weirdness with pfSense.

I've done it before with Java, don't see why it'd be different with other languages.
