Terastation web server

[PeteW1959]

I have set up a web server on my Terastation, and all is working ok if I use the ip address and port 81 as the URL.

However I would like to access it using the url of the site I am developing e.g. http://my-new-site.com to enable me to fully test a site before uploading it to my hosting site.

I thought I could do this by making an entry in the 'hosts' file e.g. 192.168.xxx.yyy:81   my-new-site.com, but it doesn't work.

Can this be done? I only want access on the LAN, not externally.

Your nameserver is your router and not your nas
you can not modify the router dns.
you can modify your pc dns

edit
C:\Windows\System32\drivers\etc\hosts
on every pc.
