FW Release Note :

1. “Enhance Firewall Rule”.
2. “Change HTTP Session timeout to 10 minutes”.
3. “Fixed config error in <Configure log page> issue”.

I've installed the D18 firmware on my 8800AXL R2 and can confirm that this update has addressed the open DNS port forwarding issue. All other functions of the router appear to be functional and stable. Thank you for addressing this issue.
