In the Outbound Rules, I set up a rule to allow outbound connection from port 26. But, it doesn't work.
However, if I allow "all port" for this rule, this will work, but then all ports will be allowed too.
What is the reason? Is there any conflicting rule? I need to fix this as soon as possible.
-Edit to add :
I'm trying to allow email access to mail server outside (port 26). The thing is, even if I telnet using port 26, it will not work, unless I allow "all ports". Specific port will not do.
