Edit rules for security profile

Here you can modify the firewall rules produced by the Security Profile settings. This should be done by experienced users only, as it requires good understanding of the rule syntax. NOTE: Once you have modified the firewall rules, they are no longer autogenerated. You can no longer use the Security Profile page for changes. Neither can you add new entries to the built-in VPN endpoint. You are recommended to use "Enter additional rules" on the Security Profile page instead.

Network Status

Connected hosts:
Overview of all network hosts attached to your unit, and their status. NOTE: To get up-to-date status, click Refresh.
Bars - Displays resource usage. Position mouse pointer on bar to view numerical values (as tooltip) of flows : bytes.
- nr of flows open to this host. Logarithmic scale. If bar is bigger than half of available space then host uses more than average share of flows available for each host.
- nr bytes transferred by this host within its currently open flows. Logarithmic scale. If bar is bigger than half of available space then host has transferred more data than the average of all hosts.
NOTE: While most data through the firewall is transferred through flows, there are other data (such as eg. VPN tunnels) transferred without usage of flows. Data transferred without flows are NOT visible here.
Icons - Displays online status. By clicking on the icon more detailed information is displayed about that host.
- a directly connected host that is online (turned on). Directly means on the same subnet, thus there might still be hubs or switches inbetween.
- a directly connected host that is offline (turned off / unavailable).
- a gateway that is online. Gateways connect networks together into the Internet.
- a gateway that is offline (unavailable). You cannot reach networks behind an offline gateway.
- a remote host. As this host is behind a gateway, not on the same subnet, online/offline status is undeterminable. TIP: Click on the host icon. If the appearing Host info page states ping OK then the host is online. If ping failed the host might be offline or not answering to pings.
- one or more SIP users registered on host.
- one or more SIP calls (media streams) currently in progress from host.
IP address of host: Italics means IP address given by our DHCP server.
Name displayed is the primary DNS name of the host (first name in DNS database with matching IP address).
Refresh... - Rescan listed hosts for up-to-date online status. NOTE: Scanning may take several seconds to complete. Please click only once, and wait for page to refresh.
Add - Add host: enter host IP address and name, then click Add to add a host to Network status list and DNS database.


Network Status, Advanced:
Routing table, ARP table - See general litterature on TCP/IP, ARP and routing to understand these tables.

DHCP server - List of assignments in the DHCP server database. PC with listed MAC address will always receive stated IP address upon request.
