router

I have an old Belkin router and when I enable the firewall I cannot access certain websites. For example:

http://www.avisynth.org

With Firewall Enabled: Main page loads and begins to do a meta refresh which never finishes.

With Firewall Disabled: Main page loads and the meta refresh completes as normal and I am taken to the wiki page.

I have not setup any rules in my firewall that would prevent this site from loading, yet it refuses to load unless I have the firewall disabled completely. My router has a hidden page with advanced settings on it for the firewall which I was able to acccess and take a screenshot of, but I did not want to mess with these values unless I absolutely have to do so:

What might be causing this problem and how would I go about fixing it?
