How to prevent IPv6 leaks under Linux, using OpenVPN?

Recommended Posts

say yer drive is incrypted your grub would look like this:

GRUB_CMDLINE_LINUX_DEFAULT="quiet"
GRUB_CMDLINE_LINUX="cryptdevice=/dev/sda3:cryptroot ipv6.disable=1 video=1360x768"

 

then recheck/build...
# grub-install --recheck /dev/sda
# grub-mkconfig -o /boot/grub/grub.cfg

 

if you do an ip link command or ifconfig and don't see ipv6 addr good sign

here's another link for debian ubuntu etc:

Hello,

 

disabling IPv6 might be too problematic in some circumstances, and in general it's an overkill solution.

 

Setting two or three ip6tables rules is a much more practical approach, and of course it is faster, you just need a second. Network Lock feature does that, in case you run Eddie for GNU/Linux.

 

Kind regards

Activating the AirVPN "network lock" does stop my ISP IPv6 address from showing up on ipleak.net ... but I can't use Thunderbird to fetch email with the network lock activated.

 

So I tried disabling IPv6 in Firefox (1. "about:config" in url address box; 2. "network.dns.disableIPv6" in search box; 3. double tapping (or clicking) to change default of "false" to "true").  That seems to work fine, as ipleak.net shows "IPv6 test not reachable."

 

But does this mean that:  -A. my IPv6 address is still leaking, and I'm just not seeing it in Firefox because IPv6 is disabled; or -B. that Firefox is actually stopping my IPv6 address from being shown on the web?

AirVPN now handles IPv6.
This is an old thread.
