Thanks for all the replies guys, and you Dan.
As it turns out, after a few beers last night, I had an epiphany.
I started thinking, maybe the traffic isn't allowed to go out and come back in due to the way it is routed. And sure enough, voila. Tested off my work wireless and bam, right in. The port forwarding seems to be working well, and pushing the DNS server for my SSH/Dyn device ti public internet has made all the difference.
So, anyone wanna buy a Linksys E3200 cheap?
