Anyone who can tell me (step by step) how to port forward my server and change the ip(please give the link of the ip changer) of it? If so, Thank you in advance and Merry christmas!
I dont know what you mean with ip changer but. If you want to change the ip of your router remove its cable from AC. If you want a domain for free check out no-ip.org. for portforwarding check out portforward.com and look for a suitable guide for your router model.
