This shouldn't happen what ever you configured you box (I mean from
networking point of view).

Well, I don't understand if you use you FreeBSD box as a router or not.

If yes, then you should have something like:
hostname="buh.cameradicommercio.ro"
ifconfig_rl0="inet 81.196.25.19   netmask 255.255.255.0"
ifconfig_rl1="inet 192.168.0.1  netmask 255.255.255.0"
defaultrouter="81.196.25.1"

where rl0 would be your outside interface connencted to your upstream
provider's router with ip address 81.196.25.1 and rl1 would be the
inside interface connected to a hub/switch with the internal machines.

You would also want to use natd on the router, because 192.168/24 is a
private address space. So you would add to you rc.conf:
natd_enable="YES"
natd_interface="rl0"
firewall_enable="YES"
firewall_type="OPEN"

You need FIREWALL="YES" for natd to work.

All this is very well explained in the FreeBSD Handbook, tahe a look at:
6.8 Setting Up Network Interface Cards
19.3 Wireless Networking
