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

    Hi ,

    Thank you for reaching out to the Community! 

    You should configure the interface IP address from the Usable IP address range. If you use the network address as an interface address, you will get an error "You cannot enter a network IP for IP address."

    In your case, the IP address 2401:0000:4000:0000:0000:0000:0000:0510 is the network address. If you use IP address 2401:0000:4000:0000:0000:0000:0000:0511, it will work. 

    Thanks,
