Can they ping locally? Can they ping the gateway?

Yes to both. Changing gateway to x.x.x.254 works (so old gateway).

Are they properly getting the updated DHCP? I have had major issues with my MBP on an older OS version with it not accepting new DHCP info when setting up a new router.
Did you set one up static and does it fail?

So the gateway address did not change, just the device that has that address. DHCP release/renew makes no difference. Changing to static address with x.x.x.1 as the gateway does not work.

OK if the IP didn't change, but the MAC address did, sounds like an ARP cache issue.

No clue then. I have never had a problem when setting one statically.
My problems always occurred when setting up a new ERL or such and the MBP kept refusing to come online with the new IP from the ERL's DHCP server.

Is the new firewall blocking those machines for some reason? i.e. the new firewall see them as an attack? Anything in the logs?

Clearing the cache didn't fix it.

I'll take a look.

after clearing it, did you look at the cache to see if the IP matched the desired MAC address?

Well, the solution was no less peculiar. In my firewall config I had specified authenticated users for LAN to WAN in my work to set up VPN. This setting affects all outbound traffic. The Macs that were affected are the ones that have not yet been joined to Active Directory. This is a really cool setting that I'll be turning back on when we're actually ready for it.

Nice to know it was working as intended, right? lol.

I'm guessing some big money for that UTM.

About $2k for each node. We have an HA pair.

I'm not sure what you're getting at.

A general consensus around ML is that UTMs are unnecessary, i.e. a waste of money. Additionally, Scott is pretty adamant that there is only one primary vendor (drawing a blank right now) that is good for UTMs.
So what I'm getting at is, what was the decision tree that lead to purchasing two $2000+ UTM firewalls? Why were they felt to be worth the value versus say a pair of Edge Routers? etc

I didn't purchase them for the UTM, but the FIPS validation. Actually saved the company quite a bit of money overall since they were going to buy Cisco ASAs.
