Oh, static IP on the computer. Yeah, already did that to no avail. -----Original Message----- Message: 7 Date: Wed, 14 Apr 2010 13:08:16 -0400 From: JohnS <jses27 at gmail.com> Subject: Re: [CentOS] timeout problem To: CentOS mailing list <centos at centos.org> Message-ID: <1271264896.3366.23.camel at ethies> Content-Type: text/plain On Wed, 2010-04-14 at 16:23 +0000, tony.chamberlain at lemko.com wrote: > I found the response below today online to a question I had. > For some reason I never got the mail.

So now you pick one ip address the router assigns from it's dhcp address block and create a static ip configuration for your eth0 nic, If the routers dhcp address block is 192.168.2.2 - 192.168.2.100 pick 192.168.2.10 for the ip. Now eth0 needs a default gateway which is your routers address maybe like 192.168.2.1. Now eth0 needs a primary and secondary DNS entry. If the isp only has one then use one else you can use the default gateway address of the router but not recomended because you are having problems so I think you need the real dns. If you log into the router you will see or find the dns entries you need and the dhcp block that is assigned. John
