I believe that I'm experiencing a form of firewall reflection.

I have a single public IP on a wan interface with nat-masquerade to inside private interface

There is a webserver @ 192.168.1.31

port 80 requests on the public (66.76.129.58) interface are dst-nat to 192.168.1.31

this is working fine.

But when you browse to http://www.4stn.com which resolves to 66.76.129.58 and you are inside on
the private side you get "page cannot be displayed" but from anywhere else in the world it works fine.

How do you resolve this?

Split the DNS or use a hosts file.

This is the reply from support:

You need to add 'src-nat' for the web-server, where 'src-address' is local
address and 'to-addresses' is public address.
Then web-server located in the local network should work for all clients
(including from the local network).

\

But this still didn't resolve this issue.

Can you post your firewall settings?

It works for me

how do I do that?

Can I somehow extract just the firewall rules?

From the console:
