Due to Telemach not giving me IPv6 and my router supporting it (WRVS4400N), due to Ubuntu resolving IPv6 updates but unable to route to them:
Mashup from PureVPN tutourial
Edit sysctl.conf:
sudo vim /etc/sysctl.conf
Append:
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1
Save, close, run:
cat /proc/sys/net/ipv6/conf/all/disable_ipv6
If equals 1, you’re done, else
sudo sysctl -p
If we get those 3 lines again, re-run the cat command. If it now replies with ‘1’, you’re done.
Restart the network, or better yet, reboot the machine…
