There are two NIC on my SBS 2003 server. There is a firewall also which is active. Now I am facing a problem with Windows Firewall when I am trying to use a different program or service. After looking inside event viewer I found that the issue lies with ipnat.sys. So the issue mostly lies with nat which is running behind firewall and it is blocking it. How can I unblock all the stuff and make it work actively. There must be any guide available on the same.
