What there are other ways to restart the network without breaking the current ssh session?

I be able to connect directly to the console.
On network interfaces, I see no ip addresses.
Likely to command "service netif stop" killing all processes dhclient
A command "service netif start" will not start dhclient on network interfaces specified in rc.conf.
As a result, I started in the console "service netif start" and the network appeared.

Later, I will try to repeat the commands on the FreeBSD 9.1
