On my network, all devices go through DHCP for an IP addresses.  Can I go into SmartSDR and under Network change DHCP to Static and put the same IP address that it currently has in the IP Address and select "Enforce Private IP Connections"?  Will the result in forcing the IP address to be static in the DHCP domain?

Probably best to do the reservation in your router so DHCP doesn't assign something else to the Flex's address when it's not on.

I HIGHLY recommend not setting a static IP address for the radio.  If you want the radio to have the same IP address all the time, set a DHCP reservation based on the radio's MAC address.  As long as you do not revert back to an earlier version of SmartSDR v2.0 where we updated the radio's MAC address to have the FlexRadio OUI, you should be fine.

Static IP addresses are unforgiving. And waste a lot of support time chasing down connectivity problems due to IP subnet changes or identical IP address on the same subnet.

Good, I was able to reserve the DHCP address in the router for the radio's mac address so I do not have to do anything within SmartSDR.

I thought the static ip address option was removed starting with smartsdr version 2.2.8 at least it does not seem to be an option on the 6400M unit.

That capability was removed only for the M models until we can add the logic to ensure that the Front end does not lose communication with the back end that can happen when only one of the ends can take a static assignment.

From what I gather, the static option is really there for commercial customers. Most ham customers should just use DHCP reservation. In my professional career, I build systems to centrally configure servers. This is how professional IT environments are these days. Logging in to each one to configure stuff gets old fast... but some need that capability. Consider it a last resort.
