I am a netwrok administrator at a small company (22 PC) and i have a problem, and i don't know which could be the cause.
I can't access a specific website from the LAN.
I have a server which has 2 NICs(one to ISP and one to LAN).
I have installed on the server (Bind DNS server and DHCP server) Debian 6 Server.
I want to mention that "nslookup mcel.co.mz", and "dig my_site" is not working perfectly,
I can't access the site from inside the LAN.
I can't send emails to person that are located in that domain. When I dig mcel.co.mz @8.8.8.8 the domain is resolved.

Why can't I view a specific websites? www.mcel.co.mz

Why can't send email to person that are on some domains? @mcel.co.mz

I don't have any rule configured in Debian Server which wouldn't let me acces the site. I am the only one responsable with the IT department.

Lowly,
