WAN link manger fails to test after link restore

Hi folks,

I have been experimenting with putting a UTM in front of the XG for when I change ISPs, they use a connection method not currently supported by XG. When I have finished my experiment for the night, I restore the connection to the XG and both links show down. Edit the WAN interface gets the IP4 connection working, but not the IPv6 even though the IPv6 has an address.

editing the WAN link  manager does not help, so a restart is required which on an XG115W is painfully slow.

This is not the case in previous versions of XG.

  • Hello rfcat_vk,

    Is WAN link restored after you restarted XG115w? Or is it still in same state where IPv6 is not working?

    Can you please elaborate what kind of connection method you are referring which requires UTM to be deployed in front of ISP? And how did you restored XG link?

    If IPv6 is not working right now and appliance is in same state, please PM access id of the appliance.

  • Hi Sanket,

    The reason for the UTM is because the XG in its current form does not support IPv6 PD for address assignment. My proposed ISP/RSP uses PD to assign IPv6 addresses.

    I power on the UTM and let is stabilise before before disconnecting the XG from the NBN modem and connecting the UTM.

    When I finish my testing on the UTM I restore the XG connection to the NBN modem. Neither IP4 or IPv6 restore on the XG.

    The WAN interface is edited which is previous version of XG usually resulted in all addresses working correctly. After the edited interface is saved the IP4 address (WAN link manager) shows as active, the IPv6 does not, after a short while the IPv6 address is displayed on the WAN interface, but the WAN link manager still sows IPv6 as failed.

    The only way to fix this is to restart the XG115W and hope the WAN interface does not die completely as a couple of nights previously. The restart time is very long and eventually the WAN link manger  indicates both IP4 and IPv6 are working.

    I hope this provides the details you are seeking?

  • Thanks Ian. Understood the purpose of UTM deployment.

    Would it be possible to share device access via PM? I would like to check WAN configuration and backend logs. Please also share XG version and timeframe when you restored link back to NBN modem. Do you think instead of restarting XG, NBN modem restart could have also resolved the issue for IPv6?

  • Hi Sanket,

    xg115w running v19.5 eap 1. I had tried restarting the nbn modem and that had no affect. I will pm you the access link.

  • Hi Sanket,

    do you need a new remote access after the restart?
