During beta I had a regular show of LEOPARDs in missions and the tower was nearly inaccessable with BEAVERs blocking my way 9 out of 10 times. [i]"Oh well, it's beta"[/i] is what I thought. Come launch, the problems had decreased, but still the occasional leopard and perhaps 60-75% of the time beavers on tower access. Since no one of my friends shared this experience I concluded that the problem was perhaps on my end after all. I fiddled with all sorts of router settings (uPnP, DMZ, portforwarding, porttriggering) but nothing helped making it better, which is rather strange since especially DMZ should be completely opening up access. So, only possibility remaining is that the hardware of the router was not up to par, or the custom firmware my ISP put on their modem/router sucked (which I believe to be the most likely case). As a last resort I set the ISP's router to bridge mode (e.g. just passthrough internet, don't try doing anything "smart") and hung an Apple Airport Extreme behind it as router. I only played for one night, but I've had zero, yes [b]zero[/b], issues so far. No sign of leopards and the tower has been 100% accessible now (10+ tries). While it might be a bit premature to draw a real conclusion, I do believe it's fixed for me. So, if all else fails, you might want to try this for yourself if you experience the same errors. Good luck out there Guardians.
