Things that I've seen that don't work right:
Using phone login and logoff for Facebook
Gmail links from email don't work on phone
Pokémon network playing on switch
Metalgear 5 online component
Appgate software VPN routing
Ipv6 to internal boxes seems blocked
For FB I disconnect from gateway to login and logout
Gmail I copy url and use it directly in browser (copying gets rid of the Google wrapper on the link)
For VPN I still have access to a normal Cisco VPN currently, so I can work around that
The video games just don't have online working, no fix.
Are these issues common or unique to my gateway?
