Will Maestro/SmartSDR 2.0 support connecting to a LAN-connected radio that is not on the same subnet?

Will Maestro/SmartSDR-2.x permit connection by specified radio IP address, via LAN, that is not necessarily on the same subnet (broadcast domain) as the 6xxx radio?

When I brought this up before, I gathered SmartSDR 1.x is restricted to broadcast-discovery of same-subnet radios because of concerns about Internet abuse. An option was then added to the radio-side to optionally restrict connections to RFC1918 private address space, which seems to me to be a stronger security measure than restricting the client discovery mechanism.

Now that FRS is providing SmartLink for safe supported secure REMOTE authentication, it would solve problems for me and others if we could connect to effectively LOCAL radios which aren't necessarily on our same subnet by specified IP address. I cannot connect to a radio in an adjacent building LAN, or via WiFi, where I am not on the same LAN subnet (broadcast domain) as my Maestro or SmartSDR. The (awesome) IOS client does not have this limitation. I am not asking if I can use SmartLink for a local to local connection and I would prefer NOT to open up a debate about why this matters or how to work around it with extra devices relaying the broadcast discovery packets between LAN segments or bridged VPNs which tunnel broadcast traffic across gateways. If this issue impacts you or you are a developer working on this software, this should be an understandable question. Thanks. -Mark Thomas   KC3DRE

Steve - Thank you very much for the detailed explanation.  My feedback would be that allowing direct entry of an IP Address into a client seems like a fairly trivial addition from an R&D resource perspective.  This would help greatly when using the radio in a VPN or multi-subnet environment where cross-subnet broadcasts are impossible or impractical.
