There are 2 ways to fix this. You can either relax the netmask to just use the first 2 octets (192.168) to define the subnet (192.168.0.0/16) instead of the default 3, or to reconfigure dhcp to offer ip addresses in the 192.168.1 subnet. Personally, I'd go for the second option - reconfiguring DHCP to offer from a range in the 192.168.1 subnet: it should be as simple as replacing the 5 for a 1 in the right config file - and make sure the range doesn't include your static ip address for the Myth box. Sounds like you've got well started with this. You'll need to refresh the existing clients once thats done to get them all using the new subnet. hth, Steve -- Steve Holdoway <[EMAIL PROTECTED]>
