all this should be done on your firewall system . <br />
no one can give you a detailed answer without knowing what kind of firewall you have.

<div class="content wysiwyg-content">
I have a block of 5 &quot;real&quot; IP addresses that Comcast gave us. &nbsp;I want to take one of those real IPs and translate it to an internal IP but only allow 4 TCP ports.<br />
<br />
So: &nbsp;Real IP: &nbsp;77.88.99.111 &nbsp; should go to 192.168.10.5 only allow ports 20, 21, 2009, 23.<br />
<br />
NSA- 240<br />
<br />
Can someone tell me what I need to do? &nbsp;(I know replying RTFM would be an idea, but I will not be accepting that as an answer, lol)<br />
<br />
Thanks.

Allow Access Internal IP Some Ports

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.
