Multiple exchange server - to Multiple External IP through one nic
-
I have multiple Exchange servers, each one has an external address, I am trying to do a one to one nat, however what happens I put the exchange server to an external IP I have a block of them, it always says its coming from the Router IP instead of the IP address I assigned.
So My mail is being blocked. Can anyone help me with this?
More detail,
PFSENSE primary WAN x.x.x.3
exchange 1 Internal IP 192.168.1.50 - external address x.x.x.10
exchange 2 internal IP 192.168.1.100 - External address x.x.x.12
exchange 3 internal ip 192.168.1.150 - External address x.x.x.14So how do I set up pfsense to respond back to the correct IP? So when I do a check on the IP address from exchange 1 it comes back x.x.x.10 and not x.x.x.3 cause I am at a loss.
Thanks

What did you configure?

I created a Virtual IP for each server and Each external IP, then I created a 1:1 nat from external Subnet to internal IP 192.168.1.50, and it still didnt work.

Screen shots of the 1:1 NAT please. What kind of VIP?

Here are the Screenshots

That sure looks like it should work. I rarely have IP addresses to play with and don't do much 1:1. I trust a 1:1 entry will take precedence over the regular outbound NAT rules.
I'm not sure about the choice of a Proxy ARP Type. I'm using ifAlias (because it's a HA pair). But it should work.
Are you sure you're not looking at an existing firewall state? What does www.wimi.com in a browser show from the server after you add the 1:1?
