Cannot join servers (Firewall problem)

  • So I got this problem with joining servers. I can see the servers but I can’t join them. I turned firewall off for a while and I was able to join servers. So what do I do now, open ports? Which programs should I add to the firewall’s allowed-list.

    I’m using a Finnish firewall called Sonera.

  • Start by adding the UDK.exe to the allowed-list for both TCP and UDP on all ports.
