UPnP Error

[Emporea]

Hey. I am struggling with this error. I already read some issues in this repo and some other forums but i cant really figure out how to solve it.

Basically I want an easy on / off switch for port forwarding in my fritzbox.

Thus I did this:

fc = FritzConnection(
    address=FRITZBOX_IP, user=FRITZBOX_USERNAME, password=FRITZBOX_PASSWORD
)
fc.call_action(
    ACTION,
    'AddPortMapping',
    NewRemoteHost='0.0.0.0',
    NewExternalPort=21,
    NewProtocol="TCP",
    NewInternalPort=21,
    NewInternalClient=SERVER_IP,
    NewEnabled=True,
    NewPortMappingDescription='Port Mapping ',
    NewLeaseDuration=0,)

respectivly this to delete it:

fc.call_action(
        ACTION,
        'DeletePortMapping',
        NewExternalPort=21,
        NewProtocol="TCP")

But all I get are these errors.. i had 401,402 and 403 so far, but this UPnPError pops up everytime...

Traceback (most recent call last):
  File "/home/coder/project/Batch_Bash/fritzPorts", line 35, in <module>
    fc.call_action(
  File "/usr/local/lib/python3.9/dist-packages/fritzconnection/core/fritzconnection.py", line 441, in call_action
    return self.soaper.execute(service, action_name, arguments)
  File "/usr/local/lib/python3.9/dist-packages/fritzconnection/core/soaper.py", line 286, in execute
    return handle_response(response)
  File "/usr/local/lib/python3.9/dist-packages/fritzconnection/core/soaper.py", line 268, in handle_response
    raise_fritzconnection_error(response)
  File "/usr/local/lib/python3.9/dist-packages/fritzconnection/core/soaper.py", line 191, in raise_fritzconnection_error
    raise exception(message)
fritzconnection.core.exceptions.FritzConnectionException: UPnPError: 
errorCode: 403
errorDescription: Not available Action

What can I do? Or is there a much easier way to activate / disable port mappings without deleting them everytime? Thanks.

I have to guess what happens here, as this error is forwarded from the router. The message also is a bit misleading: the action is known, otherwise a FritzActionError (401) should get raised. So I suppose the user has not the proper rights to execute the DeletePortMapping action.

(btw. the ACTION argument is the service-name (WANIPConn1), not the action – the action is DeletePortMapping)

Thank you for your reply. Yes, I know that the ACTION variable was not really the best choice. I have corrected it. What is the difference between WANIPConn1 and WANIPConnection1? Both are valid services and have multiple actions for port mapping. Neither works though.

I am struggling to find the reason.

• I have added a new fritzbox user with all permissions.
• I made sure to enable tr-064
• I made sure the password is correct
• A few other things

Do I need to enable other options in my FritzBox (7.50) such as UPNP or other options for this to work?

What is a good service + action to check if a login with the given username and password was successful and which rights or options are missing?

Thanks for your help.

I suppose one (WANIPConn1) is the UPnP- and the other (WANIPConnection1) the TR-064 interface and both seems to support a common subset of settings.

If setting a checkmark to "FRITZ!Box Settings – Users with this right can view and edit all FRITZ!Box settings." does not work, I have also no idea whether there are more hidden settings. The AVM documentation about TR-064 remote access notes that "There are some actions which are not completely supported for the remote access". I don't know whether this is also true for PortMappings and LAN access (may be for security reasons).

For my knowledge there is none. Some actions will just not work.
