ProSafe Gigabit Quad WAN SSL VPN Firewall SRX5308
Requirements for Entering IP Addresses
To connect to the VPN firewall, your computer needs to be configured to obtain an IP address
automatically from the VPN firewall, either an IPv4 address through DHCP or an IPv6
address through DHCPv6, or both.

IPv4

The fourth octet of an IP address needs to be between 0 and 255 (both inclusive). This
requirement applies to any IP address that you enter on a screen of the web management
interface.

IPv6

IPv6 addresses are denoted by eight groups of hexadecimal quartets that are separated by
colons. Any four-digit group of zeroes within an IPv6 address can be reduced to a single zero
or altogether omitted.
The following errors invalidate an IPv6 address:
More than eight groups of hexadecimal quartets
More than four hexadecimal characters in a quartet
More than two colons in a row
