You may set it in Configuration / Network / Proxy Settings:

I was tired to use as same but users how are on 60 subnet can’t browse internet.

and their gateway is

I am afraid transparent mode won’t work that way, did you try manual mode?
What about setting up a transparent proxy on

(ch312131) #5

i have assigned and port 3128 in nethserver.

(subnet 60 clinet can access internet if i assign on their internet explorer) but my requirement is using same 54.40 nethserver as primary internet firewall,

is it required to configure transparent proxy setup in nethserver??

can i use port forwarding for this requirement, as example, all subnet 60 http/https traffic forward to port 3128.??

And the gateway of the nethserver is Then it should work even without setting proxy for the clients.

In this case the 54.40 nethserver is firewall and proxy.

No, not necessarily, it was just an idea.

No, gateway is as its behind a router.

this requirement behind the scenario is,

01.subnet 54.0 is only having internet connection and users who are in the 54 subnet their http and https traffic route to’s say gateway is

02.subnet 60.0 doesnn’t have internet connection in physically place in there and subnet 60.0 getway is

now the requirement is place nethserver in subnet 60.0 and configure installed nethserver to communicate upstream connection with192.168.54.40 proxy for internet access of subnet 60.0 clients

I think I misunderstood you. To have the 60.0 clients using transparent proxy so you don’t need to configure your clients, you may configure a transparent proxy on the Nethserver.

As your outer proxy is transparent too you shouldn’t need the parent proxy setting. To ensure proxy is used you may block HTTP/HTTPS ports.
