trouble with upnp

[tantra]

Hello

I have some trouble with upnp.

On my gateway work miniupnpd. When uTorrent send SSDP discovery request miniupnp respond to it with follow (i see this throw wareshark):

HTTP/1.1 200 OK
CACHE-CONTROL: max-age=120
ST: upnp:rootdevice
USN: uuid:75802409-bccb-40e7-8e6c-60a44c67052b::upnp:rootdevice
EXT:

OPT: "http://schemas.upnp.org/upnp/1/0/"; ns=01
01-NLS: 1
BOOTID.UPNP.ORG: 1
CONFIGID.UPNP.ORG: 1337

but after that uTorrent can't discover host with folow messages on uTorrent upnp log:

27.06.2013 3:00:28: DEBUG: UPnP: Got a reply/notify event

If i go to http://192.168.1.1:8268/rootDesc.xml from browser (Firefox in my case) i see normal xml :

Also very strange than in wareshark i doesn't see any traffic flow for tcp peer 192.168.1.1:8268 that must be generated by uTorrent. I saw it only when make request by myself throw browser

PS: My network topology looks like this:

uTorrent ------- router ----- (gateway with nat)

uTorrent, router exist in subnet 192.168.1.64/26

router and gateway with nat exists in other subnet: 192.168.1.0/26

router exist in both subnets, and also on router run igmpproxy to properly route multicastcast traffic (SSDP requests)

Set the port manually and turn UPnP off then.

it seems i found reason. minuupnpd append additional info in SSDP request

OPT: "http://schemas.upnp.org/upnp/1/0/"; ns=01

which other upnp server doesn't do. So a patch miniupnpd (remove code that produce that aditional output) and uTorrent can setup port forwarding begin work
