i have a problem with an Archer MR600 using Iliad SIM. Internet connection works fine but VPN doesn't work.
I have done the following points
- enabled Dynamic Dns
- checked system time
- enabled OpenVpn service with standard parameters as indicated on the guide (Udp, port 1194, etc...)
- generated certificate + exported configuration
I also tried with IPSec VPN but it doesn't work anyway.
