I got a cheap SIM to test my VPN configuration before taking my GL-E750 out in the wild.
However, I’ve run into a problem connecting to my VPN server at home.
The operator supplied DNS servers give me a really old IP address for my VPN server.
I just want to override these but configuring Custom DNS Servers only applies to the E750’s DHCP clients and not the E750 itself.
I need the E750 to use a DNS server that works so it can find my home IP to establish the VPN connection.
Currently I am stuck with this crap from Lyca mobile DCHP
root@GL-E750:~# cat /etc/resolv.conf
# Interface modem_1_1_2_4
Even dnsmasq gives me a good DNS lookup from 127.0.0.1
Does anyone have a suggestion for overriding these resolvconf entries without hacking around too much?
