Security / local machine not visible from VPN.
September 29, 2021, 02:38:31 PM
I have a bunch of local machines, mostly DHCP, a few static.
We had a dual firewall setup (Watchguard, SonicWall) and I would VPN in through both, and have access to anything.
We changed our inner firewall to a Watchguard-M470, and now when I VPN in, I can see almost everything but one machine is not visible, and I cannot even ping it. Only that one machine is a problem.

So; from my laptop; local, can ping anything, file-access anything.
same laptop - VPN in, can still access & see almost everything, but not this one machine (of main interest).

I thought that having it static may be the problem, so I converted it to DHCP, no effect. That of course meant it had a different IP address - so I don't see how any incoming FW's would be able to discriminate on this one machine.

Are there log files on Windows where such networking events would be logged?

I don't know how to further diagnose this. A tracert shows it coming to the firewall, and then "timeout".
I don't have direct access to the firewall/router logs, is that what is needed?
