UPnP fails

Looks like the UPnP Port Forwarding is broken. I used these instructions to run the client: https://github.com/flyte/upnpclient

This line to try to open a port:
d.WANIPConn1.AddPortMapping(NewRemoteHost='0.0.0.0', NewExternalPort=22345, NewProtocol='UDP', NewInternalPort=22345, NewInternalClient='10.10.0.174', NewEnabled='1', NewPortMappingDescription='Testing', NewLeaseDuration=10000)

This failed with Server Internal 500 error.

I SSH'd into the Firewalla and see this internal error:
Apr 25 15:39:59 Firewalla miniupnpd[909298]: send_batch: mnl_cb_run returned -1
Apr 25 15:39:59 Firewalla miniupnpd[909298]: nft_send_rule(0x5563d0e20d20, 6, 2) send_batch failed -4

Seems like a bug in the firmware that needs to be fixed.

Box version 1.9780 (47dc7d79)
App version 1.60 (71)

  Is UPnP turned on the WAN side? also, double check and make sure the client 10.10.0.174 is there and active.

  If you checked these, let me know, I can create a ticket

  Are you requesting 10.10.0.174 from a device that's not 10.10.0.174? if you are, it will fail. (the mapping is strict, you can't request upnp from a device that's not forwarding to the mapped device)
