IPV4 versus IPV6

Post by tim777 »

Is there anyway to force mudlet 4.10.1 to use IPV4 as although my computer and the mud (Discworld) is IPV6 compatible it just hangs and never connects.
According to test-ipv6.com website i get a result of 9 out of 10. The failure is the DNS sever (BT i think) is either not able or not configured to use IPV6.
I am running Linux Mint 20.04 LTS and i can get round the problem by running the following commands in a terminal:-

sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1
sudo sysctl -w net.ipv6.conf.default.disable_ipv6=1
sudo sysctl -w net.ipv6.conf.lo.disable_ipv6=1

But its a bit of a pain.

We don't have a setting to force that, sorry. There are proxy settings - maybe that'll be an easier workaround?

Unfortunately my knowledge of proxy settings is nil so I will stick to disabling IPV6 at my end. Thanks for your help.

Sounds to me like this is an IPTables issue. I very much doubt your DNS provider will be blocking IPV6.

My router is from BT same as my service provider so I think they are blocking it

On checking my hub configuration again it confirms that IPV6 is enabled and also that DNS is NOT available
