How to turn off IPV6 on Lion Server

I did a clean install of Lion Server on my Mac Mini. I need to enable the firewall on that machine.

My Mini is only connected via WiFi to the network.

Due to firewall / Networksoftware issues i would like to disable IPV6 on the Lion Server completely.

The menu however only shows entries for "Automatic, Manual or Link-Local". On a Lion install (no Server) there is also the "Off".

Is there any reason i cannot switch off IPV6? If i cannot switch it off how do i configure my firewall so my software no longer

tries to connect using IPv6. I assume IPV6 is chosen in the first place due to a mDNS running with IPV6 enabled as i only configure ipv4 stuff and have eliminated all ipv6 completely from all other os's.

thanks & regards

Correct. Single quotes are usually used. Be sure to write the names of your networks exactly as they are displayed when you execute the "listallnetworkservices" command-- that is exactly as they appear and between (single, usually) quotation marks.

The 'off' option will now appear in Network Preferences, but it will disappear again if you select a different option and you'll have to revert to eldrik's sollution (thanks, Carapace Inc, BTW) to turn iPV6 off again.

Thank you all for posting! 🙂
