Dev OPNSense Hosting

[weswitt]

What is the recommended way to host a dev version of OPNSense for local dev work?  I tried setting up OPNSense in a VM but the presence of the VM on my network seemed to cause havoc with the traffic on my LAN.  Clearly something I'm doing wrong but some guidance as to how other approach this would be great.

Just turn off DHCP and router advertising (if enabled) and nothing should cause problems anymore.
