About Trusted IP Addresses
To ensure that requests from trusted servers are not denied, you can configure a whitelist of IP addresses so that requests from these IP addresses are always allowed. While specifying trusted IP addresses, keep the following points in mind:
*Enterprise Gateway Server supports the inclusion of IPv4 and IPv6 addresses in the trusted IP addresses lists.
*You can specify a range of IP addresses using the classless inter-domain routing (CIDR) notation. To specify an IP address range, enter the first IP address in the range followed by a forward slash (/) and a CIDR suffix.
Example IPv4 address range:
*192.168.100.0/22 represents the IPv4 addresses from 192.168.100.0 to 192.168.103.255
*148.20.57.0/30 represents the IPv4 addresses from 148.20.57.0 to 148.20.57.3
Example IPv6 address range:
*f000::/1 represents the IPv6 addresses from f000:: to ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff.
*2001:db8::/48 represents the IPv6 addresses from 2001:db8:0:0:0:0:0:0to 2001:db8:0:ffff:ffff:ffff:ffff:ffff.
*You can also specify a single IP address instead of an IP address range.
*You can specify multiple IP addresses or CIDR ranges. Separate each IP address or CIDR range with a comma (,).
