Hi @PeterUK

Thanks for keeping the symptom on your site.

After check the remote access you provide for us. We think it might be caused by the WAN trunk opt gateway settings do not update into configuration file after reboot,

Can you provide us more specific procedure about how do you reproduced this issue?

What kind of traffic or application running on the server and client under your scenario?

Is there any specific procedure between "issue happens with V4.35(AAAA.0)ITS-WK46-r90773" and "reboot on V4.38(AAAA.0)"? Since we simply tried the upgrading process and didn’t see the same symptom.

Their is no way to reproduce this issue I don't know why it happens but it seems rare and there is no link to what firmware you run to cause this issue.

The only thing I can think of is a incoming packets for DNS or SMTP happen to OPT as its rebooting or maybe delayed DHCP on OPT as its settings up.
