Which firmware for best VPN support? 220.127.116.11.318 isn't really suitable
I just started using VPN on my ASUS RT-N56U after upgrading to firmware version 18.104.22.168.318.
First thing I noticed... When connecting to PPTP or L2TP, DDNS stops working. It appears to be caused by the firmware not being smart enough to use the correct network interface to NAT out of. Also, the Internet connectivity icon shows as disabled; even though I'm VPNing out; but, seem to be other underlying issues. I get different results depending on which VPN service provider I use.
Does anyone know if there is a custom firmware that fully handles VPN/DDNS much better than 22.214.171.124.318 (without breaking other core features)? If there's OpenVPN support too, that would be great.
I never checked how good the support for VPN was on firmware 1.x.x.x (blue color UI). I know there are some custom firmwares floating around for the RT-N56U; but, dont want to install anything thats a PITA to install or has other core features missing.
