I'm using Intel servers with Intel motherboards, they are IPMI-capable and both LAN and SOL are implemented by bridging with onboard ethernet and serial port. After loading IPMI driver and configuring IPMI using ipmitool (/usr/ports/sysutils/ipmitool), SOL is accessible via built-in ssh shell that listens on IPMI IP, or ipmitool running from remote. No additional serial ports nor ethernet adapters are exposed to the system, and you cannot connect to IPMI IP from local machine. Cheers.
