Every time I try to post, it will not go through with my firewall on.

I get this message:

The host you are trying to send the input from is not a valid host.

Please use your back button to return to the previous page.

I had to turn off the firewall to post this, but I am effectively unable to post here until I figure this out, since I am not going to be unprotected.

This is the only forum that blocks me from posting.
