recently i wanted to host l4d2 games with my friends so i went to set up port forwarding, i have public ip(confirmed with tm), but after i set it up the port is still closed

i contacted TM and they told me that i need to ask TM to open every port PLUS i can only open ONE port at a time.

does anyone why this is a thing lmao everyone that i asked said it shouldnt be a problem

500mbps from SWU3.0 that they then upgraded to 800 for free, but idk if its still 800 bc i havent checked in a while. i have called TM they have confirmed i have public ip

first 2 octet is 180.73

i have the zyxel e3200-t0. i have already set my ip to static

got rate limited but ive done that and port is still closed

i also contacted TM and they die die tell me that everyone needs to contact TM for port forwarding even with different routers, even though i have people telling me that they've never contacted TM for the matter
