I was trying to sway away from nat'ing &nbsp;individual addresses, and did find a fix for it. &nbsp;I put this in my /etc/shorewall/masq file and it seems to have worked, but I still have some testing to do. &nbsp;Thanks for your response.<br />

<div class="content wysiwyg-content">
Local network = 172.20.1.0/24<br />
Needs to NAT to = 192.168.76.0\24<br />
Example 172.20.1.15 needs to be nat'd to 192.168.76.15.<br />
<br />
I'm just curious what config file I need to use in Shorewall to accomplish this and how it would look. &nbsp;Thanks in advance for your help.

Software firewalls, also known as host-based firewalls, provide a layer of software on one host that controls network traffic in and out of that single machine. Most operating systems now include firewall software, but many available software firewalls include central distribution, antivirus systems and disaster recovery.
