Chapter 1 What’s New for FortiOS 5.0 : IPv6 : IPv6 Explicit web proxy : Restricting the IP address of the explicit IPv6 web proxy
  
Restricting the IP address of the explicit IPv6 web proxy
You can use the following command to restrict access to the IPv6 explicit web proxy using only one IPv6 IP address. The IPv6 address that you specify must be the IPv6 address of an interface that the explicit HTTP proxy is enabled on. You might want to use this option if the explicit web proxy is enabled on an interface with multiple IPv6 addresses.
For example, to require uses to connect to the IPv6 address 2001:db8:0:2::30 to connect to the explicit IPv6 HTTP proxy:
config web-proxy explicit
set incoming-ipv6 2001:db8:0:2::30
end
