I think the title is accurate...
If I plug a new device into my LAN that is not on the same /24 that I need to configure, I will assign a static IP to my workstation to match the device's default IP. In this case I am using a HPE 1810G-8 switch. My LAN uses 192.168.45.0/24, my RB2011 is assigned 192.168.45.1/24 with the MAC address of d4-ca-6d-6e-88-bc.
Default IP of the switch is 192.168.2.10. I set my workstation to 192.168.2.14.
I can ping 192.168.2.10 once, then it starts to time out.
If I set this switch and my workstation to an unused VLAN everything works as expected. When just connecting to my LAN and setting the static IP, it fails.

This is just the device beside me right now. It doesn't matter what device I connect or what network it uses, except for 192.168.45.0/24.
I'm sure it is something simple, but this is really starting to irritate me.
