Discarding packet with invalid signature from *IP address*

[forsenK]

So this is nothing really annoying or game breaking but I can't figure out what I'm doing wrong. (I also wasn't sure where to put this topic since it's for the pvp dedicated servers) I started a dedicated server just to try it out, I made sure to enable DMZ host, and it did start up just fine, HOWEVER, every time someone tries to join, the server just says "Discarding packet with invalid signature from: *Ip address of the player*" and they get dropped almost instantly. Is this a known issue or something I messed up? I couldn't really find anyone else with this issue.

It might be an issue, but most of the time its the other way around: you drop packets because the player already left. Usually players leave when they join an empty lobby. Packets don't always end up at the destination in the order they were sent. So after the "leave squad" message is received, some other (delayed) packets might still arrive from that user. As there is no longer a user with that ip in the session (they left), their ip is now invalid. You can see some of the relevant messages below.
