I'm using build 18024 on my RT-N13U and port forwarding is not working.

Apparently others have also reported issue wiht build 18024 port forwarding has stopped working randomly.

Any idea how we can submit a bug report to have this fixed in the next build?

This is pretty important for me.

I cant get port forwarding to work in the n13u.b1 using any firmware version, not only 18004. Guess this is an old bug...

Ok, found the solution:

In the Control Panel click on "Administration" then on "Commands". Copy and paste this inside the Commands Sheel:

iptables -t nat -A POSTROUTING -j MASQUERADE

Click on "Save Firewall" and then "Run Commands"

I am using build 14896 on a D-Link dir 300 and i got the same issue with ports. Couldn't use ftp, remote desktop etc...
Adding the line in there did the trick.
Cheers

I found this fix worked for me on Netgear WNDR3700 running DD-WRT DD-WRT v24-sp2 (03/17/11) std - build 16454. Thankyou!

I signed up just to say that this worked for me and I am still on DD-WRT v24 (05/24/0Cool micro - build 9526 on a Linksys WRT54Gv8 / GSv7 . I should probably update, since my newer router took a dive and I pulled this one out of the closet.

Thanks a bunch.

I tried adding the suggested command (iptables -t nat -A POSTROUTING -j MASQUERADE) but does not seem to make any difference.

iptables -t nat -A POSTROUTING -j MASQUERADE

Worked like magic for me on my cisco m20. I am running the v24-sp2 (04/07/12) vpn-small
SVN revision 18946M NEWD-2 K2.6 Eko build on my router. Was banging my head on my desk trying to get RDP ports to forward correctly for hours. Strangely other ports were forwarding correctly (http 80, https 443) even without the command but RDP port 3389 refused to forward without this command even after router reboots, 30/30/30 etc. This command finally got it working. Thanks for the tip!
