WAN port LAG does not quire IP address via DHCP

LHerzog

on our SG430 with 2-Port LAG for one WAN line, we do not receive IP address anymore so that WAN line is unusable.

Cluster is HA, Firmware version:        9.711-5

When I disable and re-enable the lag interface, it tries do get IP by DHCP but fails to receive an offer.

I confirmed the ISP router is providing IP addresses.

The LAG terminates at a WAN switch where the router is connected.

In the logs of SG I see:

    I guess it would be dhcpc ? but that failed - can be seen in my first post.

    I will restart dhcpd.

    did a HA failover - lag3 WAN interface is working again. will fall back to the previous node later and check if the issue is also resolved on that machine.

    WAN was also fine after the fall back to the original firewall (rebooted it first).

    So it was some weirdness inside UTM DHCP Client
