WLC doesn't forward gratuitous arp from firewall

we have a big issue with our WLCs.

We want to secure our wireless networks with a checkpoint firewall in front.

Because of high availability we have two firewalls.

If the active firewall breaks the backup firewall sends a gratuitous arp to tell all devices which MAC is the new one for the gateway IP-address.

But this gratuitous arp is not forwarded by the WLC. Over an IOS-accesspoint it works fine. But the clients behind the WLC can't work after a failover.

We activated the "Boradcast forwarding" in the general controller settings. But it doesn't work.

Is there a posibility to forward this broadcasts?

Thanks a lot!

There are some bug-IDs which describe the problem.




I think the last one is our issue.

At the moment we use the software

Is it right that if a bug is fixed in it is possible that the bug is active in again?
