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.
