Thanks for the info. &nbsp;I'm going to do some further reading on your information before making any changes, as it sounds I could halt outbound traffic all together if i'm not careful.<br />

Hi guys,<br />
<br />
I'm now using PFSense as our firewall and am looking for a way other than 1:1 Nat to send traffic from our Mail-Server through a specific public IP we have in our pool that can be quickly changed on the fly. &nbsp;We have 126 useable IPs so were in the /25 subnet, and am unsure of how to do it. &nbsp;I still want to receive mail on the same IP we have been using, just looking to send mail out a different public IP we have<br />
<br />
The reason is, we have our Public DNS for our MX and A records for our mail server, but if an issue ever arises with say being blacklisted when we send mail outbound on that same address, I want a way to quickly change the outgoing public IP being used.<br />
<br />
IE I still want to receive mail on the same public IP we have been using, but I'd like a way to quickly change a setting to send out mail using a different public IP in our available pool.<br />
<br />
Is this possible?

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.

Hardware Firewalls

Linux is a UNIX-like open source operating system with hundreds of distinct distributions, including: Fedora, openSUSE, Ubuntu, Debian, Slackware, Gentoo, CentOS, and Arch Linux. Linux is generally associated with web and database servers, but has become popular in many niche industries and applications.
