I am trying to open up port 80 in the filters to enable web traffic.

I am also trying to do the same with FTP. For FTP I have enabled port
20 and port 21.

Very little success with both. I have done the same with ICMP and this
was successful.

In the exemptions list I've set them as destination and source interface
as any, and source and destination as any. This would really cover all

Whens filters are removed I can get out.

At this stage I'm not looking at proxying anything, just using the
routing, together with dynamic NAT.

Looking for ideas or suggestions I can attempt.

Thank you.
