<![CDATA[NAT rule is showing private address when connecting]]>I have a NAT for SMTP port 25 that works with no problem from external IP addresses but not from other WAN IP aliases. So I had to create a 1:1 rule for all IP aliases with NAT reflection enabled and now the NAT rule works with the the IP aliases. There is one problem: the destination host is showing the private IP of the source and not the public IP. What do I need to do to fix it?

Thanks in advance

Here is the correction:

I have a NAT for SMTP port 25 that works with no problem from external IP addresses (public IP) to a Virtual IP. But not from other WAN Virtual IPs. So I had to create a 1:1 rule for all IP aliases with NAT reflection enabled and now the NAT rule works connecting from other Virtual IPs. There is one problem: the destination host is showing the private IP of the source and not the public IP.

Are you talking about inbound or outbound traffic?
If inbound, what do you mean with "from other WAN IP aliases"? For my understanding, a WAN IP cannot be the source then.
