I have a server with two network cards: one card connects to a local 192.168.2.0 network and the other to a sip trunk. I have to add a third card and as soon as I put it in the server loses connection to the local network and to the sip trunk. I have tried all the settings according to the red hat guidelines and nothing works. The server stops sending or receiving packets
This is the configuration of the two network interfaces
