Help with a configuration....

Hello,

I have a RB433 with wireless card and an omni antenna…
i have configure:

LAN - 192.168.1.251
Wireless - 10.0.0.1

The route i set is:
0.0.0.0/24 to 192.168.1.254, LAN


The internet is connected through a aDSL modem from LAN with IP 192.168.1.254.


My need is how can i block Wireless users from viewing my LAN computers??
I used masquerade on Int. out Wireless but when i do this i cant ping the DNS 192.168.1.254 so i wont get internet from wireless…


Thanks, in advance
NiKu
