Getting online
- Rack the router and power it.
- Open its CONNECT tab. On WAN1, pick LINE 1 on the ISP box on the back wall.
- Cable a LAN port to your switch, and the switch to your servers.
A powered router alone is offline. Nothing earns without an internet path. A firewall can sit in front: line to firewall, firewall to router.
Addresses
The router serves DHCP by default. Two routers on one network must not both hand out addresses: put the second on STANDBY in its SETUP tab and it takes over the moment the first stops.
Your lab has one public address from the carrier. It is yours for good and does not change when you swap routers, change plan or fail over. ip wan prints it.
Dual WAN
With a line in each WAN jack, the router uses one line at a time and keeps the other on standby.
- The line in use drops: it switches to the other in 6 seconds.
- The first line comes back: after 30 seconds up, the router goes back to it with no gap.
- SWITCH NOW changes line by hand, and PREFER picks the line it uses whenever it is up.
The lamp on each WAN jack says what its line is doing: blue and blinking in use, steady amber on standby, steady red down.
Router features
- QoS priority. One device gets premium routing: x1.2 on compute and hosting.
- Port forwards. Up to 8. A forwarded hosting server earns x1.25.
- UPnP. Forwards every hosting server, but security heat settles x1.3 higher while it is on.
Heat
Traffic heats the router. Every device behind it adds load and hosting adds more. The stock fan handles a normal lab. A busy one wants a second, better fan. A router held far too hot smokes, and then its whole rack burns, network and all.
Terminal: router <r> wan, isp, dhcp, ip wan.
