R6700v3 new firmware can't use VPN TUN TCP port 443

[LionBS]

Hello there!

I had used VPN TUN TCP port 443 on my Netgear R6700v3 router and it was working perfectly.

After upgrade firmware to V1.0.4.118_10.0.90 or V1.0.4.120_10.0.91 I can't use this port (443) for VPN configuration.

How to resolve this issue ?

Anytime theres and issue after a firmware upgrade, I recommend that people start with a factory reset/reinstall. sometimes old settings can cause issues. 

If that doesn't help, then I'd try downgrading the firmware a version.
