DNS resolve issue with two SIM cards on RutX12

[mursel]

Hello there,

I have Rutx12 with two SIM cards. My windows application is trying to connect to specific hostname via websocket (ws:) and I want to connect only via second SIM (SIM2).
Problem is that this hostname can be resolved by inherited DNS servers from both mobile connections.

I tried to set “Custom redirect” under DNS → ADvanced settings, but no luck.
When I issue “nslookup hostname DNS_server_ip” I get “;; connection timed out; no servers could be reached”.

Any help appreciated.

Regards!

Hi…

Please… take a look at

Reach internal devices under public URL

Hello, In the port forwarding rule configuration, there is an option to enable NAT loopback. This should allow you to access the web server using the public IP address. Another simple option would be to edit the hosts file (/etc/hosts) to resolve the hostname to the IP address. You can do ‘vi /etc/hosts’ or: echo “192.168.1.222 example.com” >> /etc/hosts You may need to restart Dnsmasq: /etc/init.d/dnsmasq restart Kind Regards,

maybe help you…
