I need several network cards that are on the same IP range to talk to services on other IP ranges. I need it since I will connect to bacnet BBMD in different ip ranges.
I do this on a other site with kepware on a windows server. There I have 100 virtual network cards that I can set different BBMD hosts on. Or I can connect with the IP address of the PLC
From the Debian server running I can ping every site and have connection.
But when I try to make more network cards on the Debian server I can't ping from every network card. And I only get BBMD to work on one card.
Info about bacnet BBMD
More info about bacnet
I think it's has something to do with the routing table, but I'm not sure.
I made a test server to try to get the right network setup.
Anybody have any tips on what I can do?
I tride pinging from the two cards on the same ip range.
