Whats the best configuration for workstations ? (IP´s just for sample)

Proxy configuration : eth0 : 192.168.1.250/24, gateway : 192.168.1.1 DNS : none
eth1 : 200.200.200.200/29, gateway : 200.200.200.1, DNS 1 : 200.200.200.1, DNS 2 : 8.8.8.8,  port : 3128

File server : 192.168.1.1/24, gateway : 192.168.1.1 DNS : 192.168.1.1

I´m using this for workstation :
IP 192.168.1.10/24,  gateway 192.168.1.1, DNS 1 : 200.200.200.1, DNS 2 : 8.8.8.8 on Internet explore i configure proxy as 192.168.1.250  port : 3128

But the internet is to slow. What I´m doing wrong ?

Hi. First of all use your own DNS, not an outside. File, DNS and gateway are the same? Need more info on what equipment you are using. Why a port on proxy?

File server : 192.168.1.1/24, gateway : 192.168.1.1 DNS : 192.168.1.1

I dont understand still. You should only use YOUR DNS. Not the ISP on the pc. What is eth1 200....? What kind of proxy? Im sorry but your Q? doesnt make much sense. To me.

I have two network interfaces on the proxy server (UBUNTU).
eth0 internal IP
eth1 external IP
I don´t have my own DNS, can I use my proxy as DNS ?

Don't use two gateways! Only one default gateway should be defined, use static routes (if required) for the internal devices.

Any DNS server needs to be able to resolve DNS using external servers, right up to DNS root servers.
I can't see any reason why you can't use the Ubuntu device as a DNS server, but you have to install and configure the service.
