Split Lan Network in to two groups

[ryno du preez]

Hi all

I have a lan network with let say 10 users
5 users in group "A" and 5 users in group "B"

Now my problem is as follows I want the Group A to see Group B but Group "B" may not see Group A at all.

Is there a way of doing this with every one on the same network range

I've tryed shanging the sub net Group A 255.255.0.0 and Group B 255.255.255.0 But needles to say they can still see each other on the network.

The Group A IP should be in difference range like:
Grp A : 10.2.2.x / 255.255.0.0
Grp B : 10.2.1.x / 255.255.255.0
