thnak you. working on R6300v2. i had 138.13 AIO, and upgraded to 138.14 VPN with reset. funcions as main router for household without problem. however, some cosmetic issues: Captive Portal and Web Server appear in main menu, but are not implemented in VPN build; clicking on them goes to blank pages. this is fine, and may be a cleaner way to maintain than old implementation, which removed unavailable features from menues. i did not know if this is desired behavior or not. thnaks again.
