Hello, I have two LAN cards, rl0 and rl1, with different networks. What to do so they can not see each other? Here they are:

Code: 
rl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
	options=8<VLAN_MTU>
	ether 00: e0:52:67:01: ed
	inet 192.168.100.200 netmask 0xffff0000 broadcast 192.168.255.255
	media: Ethernet autoselect (100baseTX <full-duplex>)
	status: active
rl1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
	options=8<VLAN_MTU>
	ether 00: e0:52:69:01:69
	inet 192.168.0.1 netmask 0xffffff00 broadcast 192.168.0.255
	media: Ethernet autoselect (100baseTX <full-duplex>)
	status: active

Can you explain this a bit more? What do you mean by "not see each other"?
 
As long as routing is turned off this will be the case. If you do turn on routing you'll need to add some firewall rules.

I just noticed you have overlapping subnets. This is going to cause problems. 192.168/16 includes 192.168.0/24.
