Issue saving VLANS with DHCP Server

LeeSLeeS
in Firebox - Networking, Multi-Wan, VLAN, NAT, SD-WAN

We have two Firebox M370's in separate offices.
Both running 12.11.
On each of them, in the web interface, if we go edit a VLAN, and attempt to turn on DHCP server, we run into an issue. When we hit save, it appears nothing happens. We don't get an error or success message. It just sits there for about 20 seconds, then we get a "your session is expired" message.
If I go log back in, the changes are not saved, and I see my old login session still active, in edit mode. I need to log it out from the list before anyone else can make changes.

Even if I go edit a policy that already had DHCP server enabled (simply editing the description or similar), it does the same thing. DHCP Relay and DHCP Disabled work fine.

If I setup DHCP server via policy manager, it works fine, it's only doing this via web interface.

Anyone else ever see this happen before?

    Hi @LeeS
    I've seen this happen under some specific instances with LAG (link aggregation) interfaces.

    I'd suggest opening a support case so that our team can get more info about your setup. We can either match it to an existing bug, or get a new bug started for this issue.

    You can open a support case by clicking the support center link at the top right of this page.
    If you're able to, including a support file that is taken right after your session is ended can help determine if this is the same issue -- since you'll get logged out of the WebUI sessions I'd suggest.

    -Open WSM (WatchGuard System Manager) and log into your firewall.
    -Right click your firewall and select FSM (Firebox System Manager.)
    -Go to the status report tab, and click the support button. Leave FSM here for a moment.
    -Open a web browser and log into the WebUI.
    -Attempt to save the change to your firewall via that VLAN interface, and wait for it to display that your session has ended.
    -Back in the window with FSM open, click retrive. This will pull a support file from your firewall with the logs on the system right after this fails.

    Thank you,

    Happened across this Knowledgebase article:

    "When you save changes to an existing VLAN from Fireware Web UI, the screen freezes and you receive a prompt to log in. After you log in, your VLAN changes do not take effect.

    Fault reports on the Firebox indicate user space crashes for wgagent at the time you tried to save your changes."

    Seems to indicate using Policy Manager to make the VLAN changes is the workaround for now and bug FBX-28624 applies here.
