I have problem in version 6.44.1 with L2TP/IPSEC
I configured vpn server behind NAT (port forward), when i want to use L2TP/IPSEC on windows i have problem (error 809) i searched in internet and i found i must to change registry on windows but i don't want to change registry on windows because i have 200 client.
I don't know why on IOS (APPLE), ANDROID, LINUX i can use this L2TP/IPSEC , but i cant run on windows form other networks.
when i used internet from mikrotik in local everything its ok but when i want to use other network and connect to this vpn server from windows i can't, but all other devices (IOS,ANDROID,LINUX) working without any problems!!!!
forwarded on internet modem these ports: UDP 4500,1701,500
please tell me what i need to do.
