Hi, I just lost my job ( layoff) and taking a job training course about "web" now. Because COVID-19 we need to take the training from home, our teacher want us to follow this guide "https://docs.microsoft.com/en-us/tr...nfigure-l2tp-ipsec-server-behind-nat-t-device" to modify the key of "AssumeUDPEncapsulationContextOnSendRule" to "2". It works to allow me to use the VPN to make the connect. But the problem is once I enable the VPN I can't login my RT-AC86U web gui anymore from my laptop. Since I can login from my another desktop pc ( win10 also ...) , I can sure this problem is caused by the l2tp setting. Could someone can help me to solve this issue ? I need to complete this training to find another job. Thanks. The firmware I installed is 386.4 alpha Build(s).
