Hey guys what's up ? Got a question, hopefully someone can help. On one of my WL-500gP's I have the following setup. br0= 192.168.1.1 vlan4 = 172.16.1.1 Now, any machines on the 192.168.1.x network can make requests to the 172.16.1.x network and vise vera. I would like to stop this from happening. I know I have to put in a rule in my S35firewall (I think) I just don't know what. Any help, comments, suggestions, would be appreciated. Thanks again, ScarEye
