Successfully using this particular router at home, primarily for its LTE connection because there is no WAN broadband internet at this location, but unable to get VPN remote access to the Synology NAS.Is it possible to disable the DrayTek routers OpenVPN Server capability.  I wish to pass-through the router and setup VPN remote-access to the OpenVPN Server installed on the NAS.This works ok at another location, using a less complicated router (BT Home Hub with port forwarding enabled) and ADSL, connecting to another Synology NAS also with OpenVPN.Not sure if the two OpenVPN servers are clashing, or whether this is possible on an LTE connection?
