Gateways and network

Confirm that the gateway has power and that its Ethernet cable and switch port are active. Check whether the site has working internet, DNS, and time synchronization. Restart only one affected gateway after recording its status and indicators. Ask the network administrator whether a recent firewall, VLAN, proxy, or DHCP change could block outbound service. Include the gateway model and identifier, site, indicator status, IP information where permitted, and the time it last appeared online. Never place passwords or network secrets in the ticket.
