WNDR3700v2 w/ 1.5.11 - Can't Get Ports to Forward

On my WNDR3700v2, I upgraded with no installation problems to 1.5.11 using the firmware update menu and the *sysupgrade.bin file. Outbound functionality seems fine, but inbound TCP ports that I have forwarded to my web server, such as 80, 443 and 22 will not respond when I hit the firewall from the outside. Inside my LAN the ports work fine on the web server. I tried upgrading twice keeping settings one time, and manually reapplying them the other time with the same result. The same port forwarding configuration works under 1.5.10.
Has anyone else with a WNDR3700v2 upgraded to 1.5.11 and gotten port forwarding to work?

I have this model for testing purposes, and I cannot reproduce this problem on 1.5.11. Port forwarding works fine for me.
Double-check that you aren't enabling anything else (e.g. remote admin) on these same ports that you are trying to forward. Only one application can control a given port on a given IP address.

Here's my remote access settings, so I don't think those ports are conflicting:

Hi,
The problem is that you are forwarding to an IP adres that's not in your DHCP range. Try changing your start DHCP range to 10.2.8.2.
Kind regards,
Meller74.

Meller74, I doubt that's the problem, as I've never known that to be a requirement for port forwarding on any ROM. More likely he simply has made .2 a static assignment, in which case you don't want it in the DHCP range.

You need more of the statements in this matter, so that we can understand. Thank you for sharing. I hope you happy

Was this ever resolved?
I have exactly this issue with a TP-Link TL-WR1043N/ND v1
I have no issues when using another router so I know the ISP is ok etc.
I did not try this router before flashing Gargoyle, but I don't think that would make any difference.
Any ideas? I even tried DMZ but I still show as having no open ports
Thanks in advance, apart from this problem I am stoked with the features, especially the limits
