Why does using static IP in LAN stop access?

GLO · 13-April-08, 04:31 AM

I normally use DHCP to issue my IP addresses in my LAN, but as soon as i set the client PCs with a static IP address within the IP range, they all cant access the Internet, but have no problems accessing the LAN.

What am i missing?

From my experience, to set up a static IP for a computer you'll need to adjust the following settings:

-IP address: The first 3 sets of numbers should match the LAN IP address of the router, the last set of numbers should be within the range of numbers the router is set to handle.

-Subnet Mask: Generally it's "255.255.255.0"

-Default Gateway: Use the LAN IP address of the router.

-Preferred DNS Server: Again, use the LAN IP address of the router.

*Alternate DNS Server: If you see this leave it blank.

ok, thanks.

I had it all there except for the DNS details.

That makes sense, if i have left it empty, but cant i nominate a static ip address and leave the DNS to automatic?
