Hi Everyone, The new Frontier router/modem (Technicolour DJN2130) from Telstra has 4G failover built in but if you bridge it failover doesn’t work. I’ve tested this by unplugging the WAN port from the accompanying cable modem (Netgear CM450-TLAUS) and also by unscrewing the fibre cable. 4G won’t kick in. If you do the same with the factory settings config, 4G kicks in. I’d like to route and run Wireless from my MK router but am unsure about a few things. Basically I’d like the Frontier to do as little as possible. So far I would do this on the Frontier: Under WAN Services 1. Turn off NAT-PNP 2. Turn of UpnP? 3. Turn off secure mode? (not sure what that is). 4. Turn off Wi-Fi 5. Turn of DHCP Server 6. How should I setup the Firewall? I can’t turn it off completely it seems. Firewall settings are: Low mode, the firewall will allow all outbound connections. It will reject unknown incoming connections but acknowledge the presence of the gateway. Normal mode, the firewall will allow all outbount connections. It will silently drop unknown incoming connections. High mode, the firewall will allow outgoing connections to the following services: HTTP, HTTPS, SMTP, POP3, IMAP, SSH. It will silently drop unknown incoming connections. User mode, you can configure each individual rule of the firewall as well as the default behaviour. User defined options are: Answer Internet ping On/off Outgoing default policy: ACCEPT/DROP/REJECT The outgoing policy defines what is done with packets coming from the LAN devices toward the internet. Setting it to REJECT or DROP will forbid any internet traffic from the LAN unless explicitely allowed by a firewall rule. Incoming default policy: DROP/REJECT The incoming policy defines what is done with packets destined to the gateway. They can be either REJECTED (the gateway will notify the sender they were rejected) or DROPPED (the gateway will silently discard those packets). Then to manually add a new rule options are: 1. Action: ACCEPT/DROP/REJECT 2. Protocol: TCP, UPD, TCP/UDP, UDP Lite, ICMP, ESP, AH, SCTP, all 3. Src IP 4. Src port 5. Dst IP 6. Dst port Then firewall rules for IPv6 follows the same protocol. Thankyou, Matt Hall Sydney
