i share a linksys wireless ISR with a relative and i want to setup up my web , dns and , other servers to be seen from the web and people to visit my website i will buy a domain on the web to link to my dns servers once i have my servers setup on the linksys wireless ISR correctly. This project is best suited for anyone who has dealt with linksys or cisco routers or wireless ISRS. Also best suited for anyone who has taken a cisco class.
I also want to setup a DMZ (demilitariziled zone) so my wired and wireless client hosts/ nodes are invisible to internet users and my web and other servers are visible to internet users visiting my website. I mainly just want my website visible behind a linksys wireless ISR router. my relative does not mind i use her wirless ISR router. I dont not remember the model but do remember the year bought: 2008.

Depending on the exact model, you use the web-interface of your router to setup the DMZ or port-forwarding. In case of a DMZ: open the DMZ page and enter the IP-address of your server. For Port-forwarding: go to the port-forward page and forward the necessary ports (probably only 80) to the IP-address of the server.
DNS isn't setup on your own server, but on one of the servers of a domain-registry. Often you get a DNS-client from them, which sends your outer IP-address to them, so they can register changes in your IP-address. From experience I know this holds true for no-ip.com.
