UPnP with ZyXEL Prestige 660RU-T1

[vanushah]

I've got ZyXEL Prestige 660RU-T1 and UPnP feature doesn't work with µTorrent, but it works fine with eMule.

Here are some details:

When µTorrent sends request like this:

  Frame: 
+ Ethernet: Etype = Internet IP (IPv4)
+ Ipv4: Next Protocol = TCP, Packet ID = 1119, Total IP Length = 552
+ Tcp: Flags=....A..., SrcPort=7386, DstPort=HTTP(80), Len=512, Seq=1669526555 - 1669527067, Ack=204578817, Win=65535 (scale factor not found)
- Http: Request, POST /UD/
  + Request: 
  - payload: HttpContentType =  text/xml; charset="utf-8"
   - XmlPayload: 
      <?xml version="1.0"?>
    - <s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
     - <s:Body>
      - <u:AddPortMapping xmlns:u="urn:schemas-upnp-org:service:WANIPConnection:1">
       - <NewRemoteHost>
          </NewRemoteHost>
       - <NewExternalPort>
          17458
          </NewExternalPort>
       - <NewProtocol>
          TCP
          </Ne

  Frame: 
+ Ethernet: Etype = Internet IP (IPv4)
+ Ipv4: Next Protocol = TCP, Packet ID = 1120, Total IP Length = 315
+ Tcp: Flags=...PA..., SrcPort=7386, DstPort=HTTP(80), Len=275, Seq=1669527067 - 1669527342, Ack=204578817, Win=65535 (scale factor not found)
- Http: HTTP Payload
  - payload: HttpContentType = 
     Body: wProtocol><NewInternalPort>17458</NewInternalPort><NewInternalClient>192.168.1.34</NewInternalClient><NewEnabled>1</NewEnabled><NewPortMappingDescription>utorrent</NewPortMappingDescription><NewLeaseDuration>0</NewLeaseDuration></u:AddPortMapping>
     Body: </s:Body>
     Body: </s:Envelope>

Router responses like that:

  Frame: 
+ Ethernet: Etype = Internet IP (IPv4)
+ Ipv4: Next Protocol = TCP, Packet ID = 22566, Total IP Length = 215
+ Tcp: Flags=...PA..., SrcPort=HTTP(80), DstPort=7386, Len=175, Seq=204578817 - 204578992, Ack=1669527342, Win=1024 (scale factor not found)
- Http: Response, HTTP/1.1, Status Code = 500
  - Response: 
     ProtocolVersion: HTTP/1.1
     StatusCode: 500, Internal server error
     Reason: Internal Server Error
     Date:  Sun, 09 Jan 2000 09:53:01 GMT
     ContentType:  text/xml; charset="utf-8"
     ContentLength:  523
     Server:  RomPager/4.07 UPnP/1.0
     EXT: 
     HeaderEnd: CRLF

Any ideas?

E-mule capture may help (depends on what's wrong, no idea what).

Ok, here what eMule posts to the router:

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
      <s:Body>
       <u:AddPortMapping xmlns:u="urn:schemas-upnp-org:service:WANIPConnection:1">
         <NewRemoteHost>
          </NewRemoteHost>
         <NewExternalPort>
           40645
          </NewExternalPort>
         <NewProtocol>UDP</NewProtocol>
         <NewInternalPort>1044</NewInternalPort>
         <NewInternalClient>192.168.1.34</NewInternalClient>
         <NewEnabled>1</NewEnabled>
         <NewPortMappingDescription>svchost (192.168.1.34:1044) 40645 UDP</NewPortMappingDescription>
         <NewLeaseDuration>0</NewLeaseDuration>
       </u:AddPortMapping>
      </s:Body>
</s:Envelope>

The response:

That a typo or are you sure?

/me Waits for someone who knows UPnP as I'm lazy.

No, it isn't a typo.

Looks like a bug in your router's UPnP system where it can't handle a upnp request that spans multiple packets.
