Obi202 Can't close port 80 on WAN side

(1/3) > >>

SteveM:
First, the background.  The ONLY way that I've been able to avoid choppy audio in the uplink direction is to turn on QoS AND set restricted bandwidth (currently set to 130K).  Now it works perfectly.  As I understand it, and my experiments have shown, to use those settings the Obi must be in router mode, not bridge mode.  My DSL modem is a combination router / modem so to avoid a double-NAT, I set the DSL router in bridge mode and turned on the Obi firewall.

To check for open WAN ports, I ran GRC Shields Up scanner and guess what, port 80 is wide open, even with the setting device Administration > Web Server > AccessfromWAN unchecked.  Toggling the check box with a reboot between made no difference.  For kicks, I moved the web server to port 8000 and ran the scan again.  GRC reported port 80 is now closed but port 8000 is open.

Is this a bug?  How can I close the web server port to the outside world but leave it open for admin behind the firewall?

SteveM:
Bump.

SteveM:
Last bump.....

I don't have an OBi202, but since no one else has responded: if you port forward 8000 to an invalid IP address, does that solve the problem?

This is a hack that works with some routers, but I'm not sure about the OBi.

I'm having this same issue on the Feb 2015 firmware. It was fine last week, but this week it started responding to port 80 requests, even with unchecking the AccessFromWAN, disabling from the phone itself, and even forwarding port 80 to an invalid IP. What in the world is going on?
