In the last few days I have installed a new RUTXR1 with the latest firmware (RUTX_R_00.07.01.2). I have connected a mobile broadband and a fixed broadband (WAN). When only the mobile broadband is active, everything works against the Internet, but when both WAN and mobile are active or only WAN, I can not use e-mail and go to control panels on web hosts and VPS on the Internet, where a port number must be entered.
On LAN, I have DHCP active. In the event log Connection, I get this message "IP Block No entry found for IP (192.168.0.28)." I get this regardless if I use WiFi or cable, the IP address is in the DHCP range.
