IPv6: You cannot enter a network IP for Gateway IP

Khuram Raza over 3 years ago

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

Hello Khuram!

As mentioned by H_Patel, you can't use the Network IP for IP address. However you can use 511.

Also in the XG you would need to enter it this way.

Copy and paste from here and you should be ok.

2401:0:4000::511

2401:0:4000::513

tried, doesn't work as 513 is a usable client IP not gateway's IP, see my Ubuntu screen below am using 513 IP there with gateway 510 working fine.

What you are actually saying is that your /126 in not really a true /126 on your ISP's network. You still didn't answer the question about the network range you are assigned for use on your internal network. There is no use having a IPv6 external interface address without being able to use an internal address.

Is it possible to set the gateway IP using a link local address?
