Hello

I've noticed on my router, that I can only add 32 rules, after that I received an error 501.
Could anybody know more about some limitation of rules? This limitation is an effect of router
specification? I could not find anything interesting in upnp documentation, but maybe I've
missed sth.

thanks

There are no limitation in UPnP IGD specification.
This kind of limitation is implementation specific.

thanks for answer, I've got another question, it is possible to add multiple amount of port at one time?

This is not possible. The AddPortMapping method only allows to add one.
As does the AddAnyPortMapping method added in IDG v2.

maybe I'll be more specific, we are sending to a router:

Quote:
urn:schemas-upnp-org:service:WANIPConnection:1#AddPortMapping
<?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>5005</NewExternalPort><NewProtocol>UDP</NewProtocol><NewInternalPort>5005</NewInternalPort><NewInternalClient>192.168.102.14</NewInternalClient><NewEnabled>1</NewEnabled><NewPortMappingDescription>mine</NewPortMappingDescription><NewLeaseDuration>0</NewLeaseDuration></u:AddPortMapping></s:Body></s:Envelope>


if there is a possibility to send two this kind of message at one time? so I could add 2 ports at one time?

you can try to execute two soap methods at the time, but I won't bet the router will process them at the same time...
Why don't you proceed sequentially ?
1 - call AddPortMapping(port1)
2 - call AddPortMapping(port2)

I don't think that is a good idea to "flood" the router with soap requests...

When I do that my router is getting slower, I mean, it need more and more time to response:

strace.out:17:50:42.651093 write(1, "Added 3013.\n", 2Cool


I tried to 'flood' the router with many AddPortMapping at one time and it stopped responsing, so this is not a good idea, so if there is no way to change the body of http request to add more than one port, I think that I'll stay with adding AddPortMapping one after another.
