So I would need both ports to be configured with the same IP addresses of the server. Is there something that I need to configure or add to /etc/rc.conf? You may want to look at lagg(4) in LACP mode: %grep lagg /etc/rc.conf cloned_interfaces="lagg0" ifconfig_lagg0="laggproto lacp laggport re0 laggport age0" ipv4_addrs_lagg0="208.70.104.110/25" Your switch will need to be capable of LACP as well, and be configured in a similar manner.
