WAN Access Issues on LAMP Server

WAN Access Issues on LAMP Server

I am running a LAMP server and having trouble connecting over the internet.
I confirmed everything is working fine locally. All other PC's on my
network can access the server over the LAN.
The server is wired directly to one of the gigabit ports on my modem and
ports have been forwarded accordingly.
I recently moved and switched from FIOS to Comcast. This configuration
worked fine on FIOS, but not so much here on Comcast. I have a Docsis 3
modem and am on the Extreme 105 package if that is relevant to anyone.
A ShieldsUp port scan showed all ports in stealth mode.
When attempting to connect from the WAN ip, it simply fails to connect.
Also may be worth mentioning that neither FTP, or SSH are working either,
despite having the ports forwarded properly. (I say properly in that the
same configuration worked on my FIOS connection before I moved)
Has anyone else seen this issue with Comcast?
