I havent been able to port forward since i switched internet providers.
So it worked before you switched? I guess there is another NAT layer now. Did they send a new modem? If yes, check if it's not a modem/router combo. If it is, you'll have to port forward in that router too, or put it in bridge mode. If they didn't send a new modem, it's possible that you are behind a Carrier grade NAT. In that case you'll have to contact your provider how to port forward.
It's easy to find out if there is another NAT layer. Just check if the IP address shown by https://www.whatismyip.com/ is the same as the WAN address of your EMG3525-q10a, as shown in the webinterface.

Thank you for helping me. However my internet provider is forcing me to pay to put the modem in bridge mode so I gave up.0

If the modem/router supports DMZ, you can put your own router in it. In that case all ports from the modem/router are automatically forwarded to your own router.
