Air VPN Connects on Mac but Doesn't Change IP

[betacat 14]

I installed Tunnelblick on a Mac Pro tower (running Snow Leopard). It connects to any server fine but when I check my IP, it is unchanged.

Anybody know how to fix this?

...Thanks

I don't know if this is important, but I forgot to add that I also get the following warning before a server connects:

 

"Warning - Tunnelblick could not fetch the IP address information before the connection to AirVPN **** (asterisks are server name) was made."

Hello!

 

Did you check the How to section?

Yes ...thanks. I previously configured another Mac (G4, Tiger installed) with a similar setup on the same router and that one works correctly, but for some reason I can't get this computer to do the same.

Sound like Tunnelblick isn't altering the adapter settings correctly. Have your tried the AirVPN client?

Eddie doesn't work with Snow Leopard (Mac OS X 10.6). The minimum requirement is Mavericks (OS X 10.9).

Any other ideas, anyone...?

Thanks to AirVPN support, I found a solution...

I needed to disable the IPv6 protocol for my tower's Ethernet card. To do this in Mac OS X 10.5 & later:

1. Go to Apple menu > System Preferences > Internet & Wireless > Network
2. Click the active (green dot) connection (mine was Ethernet 1), then click Advanced.
3. Click the TCP/IP tab. From the pull-down menu next to "Configure IPv6:", choose Off. Click OK, then Apply.

Alternately I understand that you can disable IPv6 on your router, or block it with firewall rules (ipfw), but the method above worked for me.
