finding the right port without access to router

hello i was wondering if any of you knew a way to find a open port without accessing the router im currently at college theres no password for the router to get the internet but the port is blocked is there anyway to find the right port?

or a way to set it up the static ip address for windows 10+ cant seem to do it with the post that was posted 13 years ago

You need to set up a manual IP LAN and then set a port in the router using that address

Example:

set address to 192.168.1.2 in network settings

set a port in Bitcomet

open router in browser and match that port numberwith the one you'vechosen, both for TCP and UDP

how would i do so without access to my colleges router?

You can’t - sorry. It does need port forwarding to be set up and that needs router access
