What is the proper CLISH syntax to configure a default route via 192.168.255.1 in Gaia?

Mateus R.Jun 17, 2026

Think of a default route like a "send everything you don't recognize to this address" sign you'd hang on a mailroom wall. In Gaia CLISH, that sign is the keyword "default" used in place of a specific network, and the destination you're pointing to is always an IP address with a priority level so the system knows which path to prefer when more than one exists. The correct answer is A. The command "set static-route default nexthop gateway address 192.168.255.1 priority 1 on" is the only one that gets all three pieces right: it uses "default" as the route destination (covering 0.0.0.0/0), specifies the gateway by IP address with the "address" keyword, and includes the required "priority" and "on" to activate it. Options B and C fail right away because they point to a specific subnet (192.168.255.0/24) rather than "default," so those are not default routes at all, just regular static routes. Option D scrambles the keyword order entirely, putting "nexthop" before "default" and treating 192.168.255.1 as a logical interface name, which the parser would reject on the spot. When you see a CLISH question on the exam, check the order carefully: "set static-route," then the destination, then "nexthop gateway," then the type keyword ("address" for IP, "logical" for interface name), then the actual value, then priority, then on or off.

A is right, and if you don't understand why the others are wrong you're going to blank on a live firewall someday. The destination comes right after "set static-route" and for a default route that keyword is literally "default", not a subnet like 192.168.255.0/24, which kills B and C immediately. D scrambles the word order badly, putting "nexthop" before the destination and sticking "logical" in front of an IP address, which makes no sense since "logical" takes an interface name like eth0, not an address. The full correct string is "set static-route default nexthop gateway address 192.168.255.1 priority 1 on" and every token has a job: "default" is the destination, "gateway address" tells Gaia you're specifying a next-hop IP, and "on" activates it.

Quick win on this one once you slow down for two seconds. I initially circled C because I saw the familiar "set static-route ... nexthop gateway address ... priority 1 on" structure and the IP looked right, but then I caught that C routes to a /24 network, not a default route, so the keyword "default" in A is exactly what Gaia CLISH wants when you are pointing to 0.0.0.0/0.

D, Gaia puts nexthop before the destination keyword, that order is correct.
