Trusted Ip - Snom C620 Administrator And Provisioning Manual

Trusted IP

In addition to the Trusted Servers setting, incoming IP traffic can be filtered using an
"Allowed IP" list of IP addresses. When this means is enabled, all unsolicited IP traffic will
be blocked unless it is from one of the trusted IP addresses on the "Allowed IP" list.
You can enter the "Allowed IP" list in the 10 fields on the "Trusted IP" section. Entries on
the "Allowed IP" list must be specified as IP addresses (IPv4 or IPv6).
Three formats are supported for entries on the "Allowed IP" list:
1. IP range specified using CIDR notation (defined in rfc4632). IPv4 or IPv6 address
followed by a prefix; for example, 192.168.0.1/24.
2. IP range specified with a pair of starting and ending IPv4 or IPv6 addresses, separated
by '-' (for example, 192.168.0.1-192.168.5.6).
No space before or after '-'

Both starting IP & ending IP have to be with the same IP version

Starting IP has to be smaller than the ending IP; otherwise, all traffic will be

dropped.
3. Single IP address in IPv4 or IPv6.
To ensure WebUI access after configuring Trusted IP, you must include the IP of
the Web Browser on the "Allowed IP" list.
