UTM IPv6 behaviour

rfcat_vk

Hi folks,

this is my first post in the UTM forum for many years since I moved to using the XG.

My issue is I am trying to move to a new ISP/RSP for improved upload performance and the new ISP/RSP uses IPV6 PD for address allocation. The XG in its current from does not support PD.

A suggestion was made to use a UTM in front of the XG to manage the IPv6 component of the WAN address. So having used the UTM for many years with various versions of IPv6 connectivity that sounded like a good idea.

I built a UTM using my old mini XG ( quad core 2 ghz and 8gb of ram) so far so good. I connected it to my XG for configuration and some testing before connecting to my existing ISP/RSP which  uses DHCP PD (according to those in the know) to provide IPv6 addressing which seems strange to me because the XG picks up a /64 address on the WAN interface.

The strange issue is that the UTM only picks up a /128 and does not renew the address even after restarting both the UTM and the NBN modem. It keeps the /128 address it is assigned when connected to the XG.

What has changed and what have I missed in configuring the IPv6 functions on the UTM?

    Hi folks,

    part answer. I edited the interface without making changes and saved it the result was a new IPv6 assignment. The down side is it is still a /128 address which now appears on the IPv6 connectivity page, supposed to be a /56.

    Not much use if it cannot request the /56, so what next?
