On V4.39 with a uptime of 44 days my USG60W stopped forwarding DHCP and needed a reboot to fix it and start working again.

The DHCP server is by VPN300 with lease time set to 2mins with a subnet of 192.168.252.0/255.255.254.0

The Gateway 192.168.252.1 is on a virtual interface by OPT on the Zywall 110 this by a switch connects to the USG60W LAN1 port its subnet thats not in use nor does DHCP is 192.168.137.254/255.255.255.0 which should not be a issue.

My TV by 2.4G gets a IP of 192.168.253.0 in the subnet by VPN300 and this all worked fine until today when it stopped and had to do a reboot of the USG60W.

    Hi @PeterUK,

    What is the firmware version of USG60W?

    When the issue happened, only the wireless clients connecting to the local AP of USG60W are not able to get IP address from DHCP server(VPN300)?

    If the issue happens next time, could you collect packet trace for interface lan1 on USG60W?

    Does the Wireshark posted above not show this?

    So it happened again with V4.60(AAKZ.1) have the packet trace for interface lan1 on USG60W and did a Diagnostic info collect which I have sent to you.

    I'm going to change the WAN1 MAC back to default as that changes the built in AP MAC.
