I came across a problem today. I have two internal networks. LAN1 is main network. LAN2 is mostly Wireless Traffic. LAN2 has not access to LAN1 at all. Only Traffic to Internet. Both have Transparent Proxy Enabled for Web filtering. I find today that LAN2 can access LAN1 machines on Port 80. Once I disable Web Filtering this access is disabled.
My question is what does WebFiltering enabled open network access on port 80 to LAN1 when no firewall rules allow this.
