I have built several untangle boxes for clients, and most I use the untangle as a router. But in this one occasion I have it setup as a Bridge.
The clients original router is needed in this case, and what happened, is all of a sudden I got a call a few days ago (around when the updates were sent out) that the internet was no longer working and they were not able to get ip addresses.
Somehow your update did this to my connection:
Bridge mode stopped passing DHCP requests through the bridge to the router on the other side.
And after the reboot even with clients that had the ip information hardcoded it would no longer transmit traffic from the network through the untangle box to the gateway, as if It 'forgot' its settings.
Now I like the fact that you automatically roll out the updates, and of course my home network my untangle is setup as a router not a bridge, but you might want to look into this..
I scratched my head, looked at the router, checked the untangle box to see if it had crashed, checked the switches, did some diagnostics, I could ping my server, the router, and some other stuff from the untangle box, but I couldn't route or send packets through the box.
So, I decided to, re-run the network wizard on the untangle box, and Voilla, everything worked perfect.
I realize this configuration probably isn't nearly as common as using it as a router, but for next time, if you could test the funtionality of a machine running in a bridged mode before sending out the update and maybe figure out 'why' it did this would be nice.
Thanks,
Mike
