I Don't think the archer MR600 supports IPSec VPN, there's no such option in archer MR600, you could be mistaking, and i have to say i'm VERY Disappointed at you guys and i'm sorry but i Won't be buying any other TP-Link products because of the poor feature support quality and I hope one day there could be a new firmware on the MR600 to support connecting to a VPN server like PIA, Express, Nord. and I see no reason to not support that since it's already easy to connect to a VPN on a phone but why not on the router so every device can connect to the VPN automatically
