Mudlet - Forum

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

This is an issue that has been hanging around our necks for a while:
