We receive an error that the 128 subnet mask is not allowed and through trial and error discovered that only a /64 seems to work. Is there any kind of workaround to allow us to use a /128 subnet mask for loop00?</P></BODY></HTML> Sun, 17 Jun 2018 03:13:23 GMT https://community.checkpoint.com/t5/General-Topics/IPv6-and-128-loopback-with-Gaia/m-p/31773#M6647 Alex_Zhdanovich 2018-06-17T03:13:23Z Re: IPv6 and /128 loopback with Gaia https://community.checkpoint.com/t5/General-Topics/IPv6-and-128-loopback-with-Gaia/m-p/31774#M6648 <HTML><HEAD></HEAD><BODY><P>You should see by default ::1/128&nbsp;in lo interface details&nbsp;and able to ping it.&nbsp;</P><P><IMG class="image-3 jive-image" src="https://community.checkpoint.com/legacyfs/online/checkpoint/66444_pastedImage_3.png" /></P><P>In R80.10 gateway you can add/128 interface.
