I'm trying to get UPnP working with Warframe through my OPNsense firewall. After enabling UPnP I am receiving a message that UPnP is malfunctioning.
Using wireshark I am able to see the handshake between the UPnP daemon and Warframe, it seems there is some sort of error along the way. A 500 error is returned to Warframe.
UPnP Error code 713: SpecifiedArrayIndexInvalid
I'm going to guess this is a bug in how Warframe is talking to UPnP. I'm attempting to debug this a little further but thought I might see if I could get some help here. Here's a link to the wireshark dump of the handshake. https://www.dropbox.com/s/qjn6idqk8i48o3d/warframe_handshake.pcap?dl=0
