dns and dhcp server on lan - what's the correct setup?
I have a linksys router in gateway mode connected to the modem from my ISP. Just wanted to let a pc do dns and dhcp so that I could set a domain name and access my computers like "name.domainname" when on the lan. No need to access from outside. It seemed to work well for a few hours, when suddenly network became extremely slow. I noticed when I did ping from the dns/dhcp server I got "no buffer available" error, which leads me to that the server got too many requests or something. I have disabled dhcp on the router and have it forward UDP and TCP on port 53 to the dns/dhcp server. On the server I have its network interface use static IP. Rest of the pc's use dhcp.
Is this the correct way to do it?
