Firewall
See Logging into the ONT for help with logging in.
1. Select Security from the top-level menu, then Firewall in the left-hand menu
2. Use the drop-down box to select Security Level
Choose the security level from the drop-down menu: Off, Low, or High
- Off: No firewall security is in effect.
- Low: Pre-routing is supported: port forwarding, DMZ, host application, and host drop. Also supported are application services: DDNS, DHCP, DNS, H248, IGMP, NTP client, SSH, Telnet, TFTP, TR-069, and VoIP. The following types of ICMP messages are permitted: echo request and reply, destination unreachable, and TTL exceeded. Other types of ICMP messages are blocked. DNS proxy is supported from LAN to WAN but not from WAN to LAN.
- High: Pre-routing and application services are not supported. UDP Port 8000 can be used to access the services; for example, FTP can use 8021, and Telnet can use 8023. Regular UDP cannot be used. RG access is permitted via the LAN side but not via the WAN side.
