Hi,
today I have installed fw 3.022 on GL-AR300M. FW 3 sure is more strong but, in my opinion and for my application it was not useful.
- second my opinion che cechbox in openvpn “if no vpn connection, no internet” is usefull.
- VPN policy is not complete and does not cover all conditions
- the thing that helped me is the guide made available: Openvpn configuration to avoid the default redirection (all through the VPN) - #6 by kyson-lok
- fw 2.27 has a gui for sms. I know that in fw 3 is installed sms3tools but it is not symple to use it.
- sometimes login does not work. The gui does not recognize the password. Then with putty is necessary to restart the router and then it work.
In my opinion fw 3 is not a robust and complete version. But I love the same my GL-AR300M
Best regards
