Since I first connected to the internet I had a normal modem, so I didn't have to mess with all this annoying stuff.But family members decided, let's get a router and I said "why not?" worst decision ever.
Anyways, After 3 days I finally found out how to log in the router admin cpanel, but now it's getting messy.
There are so many options everywhere, I'm just lost.
Any help would be appreciated, I need to forward port 7777.
Can you list the exact error message? There should be no reason why it won't let you use a LAN address.
Also, if you are hosting game servers, you will need to open those ports in your firewall. I'm assuming you are using standard windows firewall, but you didn't list your OS. When launching your game server, windows might even popup a message saying the program is trying to access the internet, allow it?... in which case, answer yes.
That is not a LAN address, that is a WAN address. It appears your ISP is in romania. You need to be using private LAN addresses on your computers.
Page 34 in the manual shows your LAN (local) addresses. The default for the router is 192.168.0.1.
You need to manually assign your computer an IP address that is on this network. Make sure it's out of the DHCP range you have setup in your router, again, page 34. For example lets say you setup the DHCP setting for LAN1 at 192.168.0.10. You can now set your PC to use 192.168.0.2. You can then port forward to this address.
