Question : Cannot see webpage from inside local network

Im not sure exactly what im looking to ask here but I have a WAN ip of lets say "111.111.111.111" and I have a webpage setup there and my router has the ports forwarded to it so that when someone from outside the network goes to this web address they get to my page just fine. Lets say now that my web servers address on my lan is 192.168.0.10 if i want to go to that address from inside the building i can and up comes my web page. But if i use the address 111.111.111.111 from withiin the building or local lan, I get forwarded instead to my dsl modems configuration page. lets say my dsl modem is 192.168.0.20. So why when I type in 111.111.111.111 from inside am I directed to my modem instead of my web server and how can I fix this. I want my users to be able to go to our web site with the same address wether they are in the building or not.

Answer : Cannot see webpage from inside local network

Another option:

On your Server, create a new forward lookup zone in DNS called domain.com (where domain.com is your external domain name)...  Create a host record for your Server in the new forward lookup zone.  Make your Server a Name Server for the new zone.  If your internal clients are going to use multiple host headers to go to different addresses, i.e. mail.domain.com, smtp.domain.com, www.domain.com, create assosciated Host Records for each header value...  Create associated CNAME Records for any header value that is associated with your server:

DOMAIN.COM
(same as parent folder)      Name Server (NS)            NT1.DOMAIN.LOCAL
NT1                  Host (A)                   192.168.0.10
MYWEB            Alias (CNAME)            NT1.DOMAIN.LOCAL
MAIL                  Alias (CNAME)            NT1.DOMAIN.LOCAL
MYSITE                  Host (A)                  62.48.192.51 <---- Assumes an offsite hosted mysite
WWW                  Host (A)                  66.142.78.23 <---- Assumes an offsite hosted www
