So i got a gl-MT300N-V2 and i’m wondering how to change the ttl on it.

i did some googling and found this line on this forum
iptables -t mangle -I POSTROUTING 1 -j TTL --ttl-set 65

but i can’t figure out how to enter it anywhere

Try to add to the end of /etc/rc.local.

Yeah but how do I get to that file to edit it?

Try SSH to the Router - GL.iNet Docs

If the router disconnects and then connects to other WAN or WWAN, ttl change for devices after the reconnect will be flushed with the new firewall restart? I believe his line is put in /etc/firewall.user maybe you meant this one for rc.local
echo 65 > /proc/sys/net/ipv4/ip_default_ttl
