There are simple network, one is nethserver server with one WAN,One DMZ and Two LANs, and one is connect to Internal network(Router & Firewall) via LAN1 interface of the Nethserver and proxy server is LAN2. more detail in attachment.
I can be managing via web interface the Nethserver form Office Network (192.168.15.0/24) I mean, the connection is reach each other, but
a Office Network (192.168.15.0/24) can not access internet via 192.168.20.2(proxy) port 3128
I am not clear why I can not access internet from Office Network, some expert please recommend.
Other question is how to Office Network reach to DMZ?
