Using a RUT950 as a 4G router. We connect the RUT950 as a VPN client to a PPTPD server via 4G, and use the VPN as the default gateway . This works fine - traffic from the LAN is routed via 4G to the PPTPD server. BUT we can only connect to the WebUI via the WAN, ie. the PPTPD client address. We can't connect from the LAN to the LAN address of the RUT950.
Until recently this worked fine, until we did a firmware update, now impossible to get in to the WebUI from the LAN. Why would that be?
TIA
