====== Configuring the Internet Gateway ====== The Internet gateway router is configured via a web browser. The default behaviour is to use DHCP to obtain an IP address from the ISP (this should always be ''137.44.152.169'') and to use DHCP to allocate addresses. We don't actually need to change anything as none of our reconfigured hosts will actually use DHCP anymore and the default of using DHCP to allocate a host in the range ''192.168.1.100''—''192.168.1.150'' will continue to be useful if we need to quickly add another host to the network. As the interface inet-gateway (''192.168.1.1'') is the default gateway for ''venus'', ''saturn-if1'', and ''jupiter-if1'' the gateway should continue to work as it would in an automatically configured network. We may need to tune the settings to get the gateway to route to ''jupiter-net'' and ''saturn-net''. The only thing we still need to do is to configure DNS for the hosts on our network. The gateway router ''solaris'' obtains these for us from the ISP using DHCP. If you open the graphical networking applet (//System->Administration->Networking//), you will probably find that these values have already been set from when you installed the operating system. If so, leave them alone. If you have no DNS servers set yet, it is easy to add them to the DNS configuration for your network. To add them manually edit the file ''/etc/resolv.conf'' so that it contains the lines which define the UWS name servers: # These are the nameserver settings to use at UWS nameserver 137.44.1.20 nameserver 137.44.1.27 nameserver 137.44.1.46 After making these changes and restarting networking: icct@myhost:~$ sudo /etc/init.d/networking restart you should be able to reach all hosts on the private ''icct.com'' network, and the Internet by name. If you can't, we will need to troubleshoot your settings. ---- [[eg-253:network:step5|Previous Step]] | [[eg-253:network:home|Home]] | [[eg-253:network:step7|Next Step]]
