- Do you have multiple computers using the same external IP address (LAN)?
- You must use ports consecutively to allow this to work.
- For example: You have internal IPs of 184.108.40.206 and 220.127.116.11.
- The first IP 18.104.22.168 would need port 6112, the next IP 22.214.171.124 would need port 6113.
- Make sure to install all current patches. If you cannot download from battle.net, here is a list:
- Reduce the problem to the router or computer (do each step separately):
-Connect MODEM directly to computer, test.
-Turn OFF all software related to firewalls, test.
- Make sure your modem doesn't include an internal router/firewall. Research this information before posting.
- Check the Options menu in the game to make sure the port number matches the port you are forwarding.
- Use a static IP address (prevents the internal IP address from changing).
Fixes/Information for other common problems:
-Temporary Restrictions/IP Bans
