I reside in an apartment complex where the internet services are not controlled by the management, but instead, they are managed by our ISP, Telcom. Unfortunately, Telcom restricts certain functionalities for users, such as not helping with the opening of ports or providing the admin username/password for my router. Additionally, my router doesn’t appear on the network tab of file explorer. Given this situation, what options do I have to address these limitations to port forward?
The only way it would not would be if the ISP only allowed TCP ports 80, 143, 443, 465, 587, 993, and 995. Many public hotspots in my area do this plus deep packet inspection. You would need OpenVPN or SSH for a TCP-based VPN and then a means to disguise your traffic to look like an https session, over say, port 443. It’s not easy to defeat but very doable.
