Question about Portforwarding.

[mokey900 0]

Is there any way to setup a port forwarding tunnel?  I need to use a tunnel because when I log in to my Minecraft account with the vpn on the minecraft launcher says that my account information isn't valid but with the VPN off it works fine. All I need is some sort of way to portforward with Air VPN without changing my IP address.

It is known that VPN servers' IP addresses cannot login to Minecraft services. If you want to connect while being connected, add exception routes for mcoapi.minecraft.net and authserver.mojang.com via your ISP. The current IPs you get by resolving them with nslookup for example are sufficient. Make sure to first close the Minecraft Launcher before you add the routes.

In Eddie you can set them in Preferences > Routes. In the IP/Hostname/Range field, simply enter the domains, and in the other field "Outside the tunnel". Then reconnect to apply them.

If you happen to use vanilla OpenVPN on Linux, I made this a one-line alias to be executed whenever you really need the routes (in other cases it should go over VPN):

alias setmcdns='mcoapi=$(dig a in mcoapi.minecraft.net +short);authserver=$(dig a in authserver.mojang.com +short);defroute=$(ip r|grep default|cut -d " " -f 3);sudo ip r add $mcoapi/32 via $defroute;sudo ip r add $authserver/32 via $defroute;'

Copy everything between the ' ' to execute it like that in a terminal.

Open the launcher again and try to login.
