So I have what I would consider a relatively complicated situation, that I can’t figure out. I am operating in an application where a Balance 30 LTE is used on a marine vessel to create a LAN that chooses from various internet sources depending on availability. It uses the WAN1 port for a primary connection in the “home port.” The WAN2 is a backup priority that is used for “guest marinas.” Then finally the cellular as another backup priority, is used when the vessel is in open water.
On the vessel there is this system called a garmin marine network, the only relevant part of the system is that all of the chart plotters have build in DHCP servers to provide addressing to any device that asks…the most important part is their server parameters cannot be modified and they do not provide DNS or Gateway information. Strictly private addressing.
the garmin system also has a iOS app that searches a predetermined stack of ip addresses for the plotters to be accessible in the app.
the issue I’m having is… Other devices in the network tend to get addressing from the garmin network instead of the pep link dhcp server. Some of the network devices such as SONOS do not allow for static IP address. Other devices such as cell phones would be hard if not impossible to constantly set static addresses for as they are always changing.
My solution would be to setup VLANS to separate the two networks… By port… I can physicall separate these two networks easily… The garmin network doesn’t need network/internet access but the "user network
does, and also needs to be able to see the plotters to use the iOS app…
sound impossible ? I’m up for ideas here…
