Can't access some servers
I notice my home internet can't reach some servers. i.e. some server on AWS US region and some game servers. All the devices on my home have same issue. Firstly, I suspect the WAN IP is banned on som...

Community Power UserIt's not likely that the WAN IP was banned. For residential connections it's extremely rare unless someone was doing some rather illegal things online.
Which router do you have from Telus? Which DNS are you using? What error messages are you seeing? Do you have any specific examples of servers you can't reach? (IP address or URL)
Router model is NH20T. DNS are 75.153.171.67,75.153.171.116 which is got from upstream device via dhcp. DNS should be OK since it can resolve correct IP address. I just figure out it isn't related with IP address. It does be related with the port. It looks like only outgoing 443 and 80 ports are allowed. i.e. following 2 wss URL aren't use default 443 port and can't access. It is very unreasonable that Telus block my outgoing ports and only allow 443 and 80. For incoming traffic, only 443 and 80 opened is OK. Will report telus support for the issue.

None of the outgoing ports are blocked by Telus. Inbound connections do have some restrictions though. Those have been publicly available for years though.
What are you doing with WebSockets? I guarantee support will have zero clue what you're asking if you mention anything to do with those.
Do you have your own router connected to the NH20T or are you directly connected to it? Have you messed with the firewall settings on it, or the router, or your computer?
speedtest website will use websocket connection to fetch something. And some game server will use websocket also. Websocket is very popular protocol on internet. websocket can host on 443 port also. If it hosts on port 443, it works for me. But if it hosts on ports except 80,433, it won't work. I can't connect a ssh server(port 22) on public IP either. I do not have any route between my device and NH20T. My device connects with Telus WiFi 6 boost and boost connects with NH20T directly.
