I'm using OpenWrt White Russian with X-Wrt Extensions 0.9 (Webif2 r2687) on my Linksys WRT54GL v1.1.
miniupnp is installed but uTorrent is complaining that there is no incoming connections. Port check (http://www.utorrent.com/testport.php?port=<p>) also fails.

But in Windows, under the Gateway Properties, I can see the port mappings, they are correct.

uTorrent log shows me:

[21:52:57]  UPnP: Discovered host: http://192.168.<x>.1:5000/rootDesc.xml
[21:52:57]  UPnP: Discovered new device: http://192.168.<x>.1:5000/ctl/IPConn

[21:52:57]  UPnP: Getting external IP
[21:52:57]  UPnP: Got external IP: <y>.<y>.<y>.<y>

Finally, connecting to the router:

The port is truely closed, can't connected to it.

Can anyone tell me how to get it work? (Shall I get provide more info? What and how?)

I had the same issue with ktorrent, and just as with Oleg's firmware, UPnP was not working (I do not know what UPnP daemon Oleg uses). I switched back to static forwarding by the router's firewall, for what it's worth...

It must be working. Any ideas what to do? Replacing by other upnpd (linux-igd?) can be a solution?

Well, you say it yourself. Did you try the alternative? As i say i never checked what daemon Oleg's firmware uses, but it did not work (or only half of the time).

OK, I tried linux-igd, and it works perfectly!

However, it was a bit tricky to install it (at least by webif2): I had to issue 'ipkg update', then 'ipkg install libpthread', after this webif2 was also able install linux-igd.

Both nat AND filter tables should be checked :

iptables -v -n -t nat -L PREROUTING
iptables -v -n -t nat -L MINIUPNPD
iptables -v -n -t filter -L FORWARD
iptables -v -n -t filter -L MINIUPNPD

i had some issues with getting upnp running with my bittorrent clients (utorrent and transmit, mac) untill i found the post above me, but it took me quite a while to figure out what to do with it..

Just copy/paste line by line from the code part of the beforementioned post into a terminal with a working ssh/telnet connection to the router.

that and removing all previous attempts (uninstalling software components) and installing only the miniupnpd v1.1-5 package enabled both my clients to respond with a green light next to the port number.

sorry for stating the obvious, but for some users (me included) its good to have a detailed description when searching for a solution

I'm using OpenWRT Backfire 10.03.1-rc4 on a Buffalo WZR-HP-G300NH. I have installed miniupnp and enabled it.

# opkg install luci-app-upnp miniupnpd

# /etc/init.d/miniupnpd enable
# /etc/init.d/miniupnpd start

I then ran the four iptables commands in the previous post and rebooted the router.

I can see the relevant ports in the firewall like the original poster, but the port does not forward. I can create a static NAT rule, so I'm confident that the service in question is live and that it's only the miniupnp that isn't seemingly forwarding the ports.

Any suggestions on how to debug?
