So I recently bought this new isp, stormfiber, which is run by cybernet and I tried to portforward and it worked just fine, my NAT Type was Type 1 in call of duty, but ever since my router crashed, the repair guys came in and it won't forward anymore. I've tried dmz and all, and I even port forwarded the port the game told me to forward, but there is still no effect. I even tried upnp but still no luck. I use a wireless connection and I play on my ps4. I've implemented a static ip too. What to do?
