This week is starting out complicated. I have a ton to do for work and absolutely no motivation to do any of it, so I'm having to spend more willpower than I'm used to just to get started. I'm coming off of a bad weekend mood-wise and really feeling the "want to run away to a cave and live there forever" vibes, which is also taking effort to move past.
One thing that's cheering me up is planning out the details of some house changes for August/September, which hopefully will end up going well. Visualizing the end result is giving me something positive to look forward to.
Your ISP controls what ports you can access using one or more firewalls and traffic control devices somewhere past the point where you connect to their network.
They can block whatever ports they want. The only way around this is to use a VPN, which creates a tunnel directly from your device to a remote server to route traffic. This still goes through your ISP and whatever firewall they have but does so over a port that they (probably) don't block. They can't see what ports your web or network requests are using so they can't block it directly.
Depending on your technical know how and what type of router you have, you could set up a VPN at the device level (PC, phone, etc.) to send just requests from that device or at the router level which could send all traffic from your network through the VPN.
It's important to remember when using a VPN that the VPN servers can still see (and potentially log) all of your traffic, even if your ISP cannot. You still need to find a VPN service that you trust to not monitor your traffic.
