Hi

I have Network LAB for Nethserver

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.
Issue:
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?

Thank you,
Yaya

Hi,
You have configured your Hardware NethServer with 4 ethernet?

Example:

eth0 = WAN (RED) ISP
eth1 = LAN (GREEN) DHCP server NethServer
eth2 = LAN (GREEN ROUTER) Your router acts as DHCP server?
eth3 = DMZ

Send us screenshots of your settings

regards

Hi

All eth0-3 set Static IP and routing is work as well

OK
but NethServer is running as DHCP for your ethX network? Send us screenshots of your settings

You can configure the access from the zones created

for example:

Green to the DMZ or DMZ to the green
Green to the Guest or Guest to green
Guest to DMZ or DMZ to Guest

all this in the firewall settings, firewall objects

Hi,

It’s normal.
Two GREEN are isolated one from other.

You have to make rules to enable communication ( LAN1 to LAN2 and LAN2 to LAN1 ).

Another point, I don.t really understand the proxy at 192.168.20.2, it’s another SERVER? Why don’t you user NethServer for proxying?

The Office Network can reach the DMZ cause of internal predifine rules:
GREEN > BLUE > ORANGE ( DMZ ) > RED
More details in the NethServer DOC…
