Some players have found the following website useful for configuring ports with a static IP to attain a more open NAT type with many different router models:
http://www.portforward.comAdditional Ports to Forward for GTA Online
GTA Online requires the following ports to be open:
TCP Ports: 80, 443
UDP Ports: 6672, 61455, 61457, 61456, and 61458
Also try:
1. Make sure your router's firmware is upgraded the latest version (very important).
2. Unplug your router for 10 minutes and plug it back in. Some older routers degrade in performance over time until it is rebooted, similar to a PC.
3. Disable any firewall or other network filtering for the game.
4. Enable or disable uPnP (universal plug and play) on your router or the console settings.
5. If you don't care about security, enable DMZ (de-militarized zone) on your router for your console’s address. This turns off all of your router's firewall features for that specific console.
6. Contact your ISP and ask them what your DNS settings should be. Check the Primary and Secondary DNS settings on your console. For more information, see:
http://manuals.playstation.net/document/en/ps3/current/settings/connectadvance.html, http://support.xbox.com/en-US/xbox-live/connecting/connection-error-solution7. If you have a combination modem/router unit or ADSL, try setting the unit to "Bridge Mode" to bypass the router part of the hardware. If this fixes the issue, then you may be able to connect a second router between the combination unit and the console to dial the PPPoE connection.
8. If you use an ADSL connection, see if dialing a PPPoE connection from the console improves the NAT Type. Contact your hardware manufacturer manual or ISP for detailed instructions.
9. Some players have found that changing MTU settings can improve their connection. Try changing your MTU to 1473 on your console or PC. For instructions on how to do this, please search
www.portforward.com for your router model and follow the instructions there. PS3 and PS4 users can follow the instructions here:
Go to Settings and then to Network.
Go to Set Up Internet Connection, and select “Custom”.
Don’t change any other settings except “MTU” to 1473. If this does not work initially, you may want to try a lower number (such as 1450).
Ako baš neznate postaviti neke stvari onda možda bolje da se i ne igrate...
Uz to kako bi bili 100% sigurni da ća igra proći odite na strat i upišite widnows firewall with advanced security
Zatim inbound rules kliknite
pa s desne strane new rule i izaberite program. Dodjate sva 3 .exe od GTA V! I sve na allow
Isti postupak ponovite i sa outbound rule
Te za kraj za svaki slučaj možete na isti način otvoriti i portove samo što onda umjesto program izaberite port i upišite port koji ste prethodno otvorili na svom routeru.
