IPv6: You cannot enter a network IP for Gateway IP

Khuram Raza

Greetings,

Sophos XG is not accepting my IPv6 config while all other devices including Windows and Linux Hosts accepts.

i get error "You cannot enter a network IP for Gateway IP"

my ISP assigned config as below 

IPv6 POOL-2401:0:4000::510/126
Gateway-2401:0:4000::510
Uesable-2401:0:4000::511~2401:0:4000::513

any ideas

    Hi Khuram Raze,

    The current version of XG  requires a NAT on your IPv6 firewall rules, so you can use any IPv6 address range internally at this stage.

    I don’t think it works in IP4 networks and from memory it doesn’t work on Cisco asa. None of the isps I have used over the years provided a network address as a gateway, they were /32 or /128 even on business networks.

    I suspect you are confusing your device’s address with the gateway address. 
    please post your pfsense network screen shot.
