Network settings for Linux behind Wingate

This tutorial is no longer regularly maintained -- no questions please.

These are the manual settings for networking a Red Hat Linux 5.2 machine behind the Wingate proxy/firewall. It assumes that Wingate is working fine with other Windows machines (see Wingate HelpDesk if you don't know how to do it) and you are setting up only the Linux machine.

You should also have installed and setup the network card in the Linux machine as eth0 (see Linux Ethernet-HOWTO if you don't know how to do it).

You need to create or edit a series of files as follows:

• /etc/HOSTNAME
  LINUX-NAME      ... name of your machine without domain, e.g. PCLinux.

• /etc/hosts
  127.0.0.1         localhost
  192.168.0.1      gateway      ... the name of the machine running Wingate
  192.168.0.x      LINUX-NAME     ... the IP and name of the Linux machine
  .............     xxxxxxxxxx        ... IP and name of all other machines in LAN

• /etc/resolv.conf
  nameserver     192.168.0.1      ... the machine running Wingate

• /etc/sysconfig/network-scripts/ifcfg-eth0
  DEVICE=eth0
  IPADDR=192.168.0.x      .... IP of the Linux machine in LAN
  NETMASK=255.255.255.0
  NETWORK=192.168.0.0
  BROADCAST=192.168.0.255
  ONBOOT=yes
  BOOTPROTO=none
  USERCTL=no

• /etc/sysconfig/network
  NETWORKING=yes
  FORWARD IPV4=yes
  HOSTNAME=LINUX-NAME
  DOMAINNAME=ISP-domain      ... I believe that it can be left blank
  GATEWAY=192.168.0.1
  GATEWAYDEV=eth0
  

NOTE: Of course do not include the comments starting with     ...

You can enter all the above information using the graphical interface of the Network Configuration tool in the Control Panel if you are using Red Hat 5.2.
