Nope. You fix it by unplugging one of the NIC from the hub and
aliasing its IP address to the other. Putting two NICs on one
collision domain can only hurt your network performance. You should
only be using one NIC.

Your rc.conf would have,

  ifconfig_fxp0="inet 209.xxx.xxx.xxx"
  ifconfig_fxp0_alias0="inet 192.168.1.2"

Or to do this on a system that is up,

  # ifconfig fxp0 inet 209.xxx.xxx.xxx
  # ifconfig fxp0 inet 192.168.1.2 alias
