|We had an IT person that went AWOL, our firewall config was never viewed or backed up. Firewall was reset to factory defaults. :(|
We have an ISP that goes into the Firewall (netgear FVS318).
We have a Dell Windows 2003 Server. We have exchange server for email running, don't host a website here, but did have a VPN setup (I believe) for remote server access and remote email access for some of our users.
Can access the Windows 2003 server and firewall, no problem.
I was successful in getting internet working for the all users, put in the primary IP info, gateway, etc., it works great. On all client computers ONLY.
However, Internet on the server does not work, email (exchange server) doesn't work and can't access the server remotely any longer. We also have a network printer that I can't access (even with the IP).
Next, ports and IPs, ports I was looking for definitives on which ports should be open and ranges on the firewall for Windows 2003 Server, didn't find much on this, there are defaults in the firewall, but they don't seem to help since things server are not working.
I am at a loss. What should I try next? Looking for some help. Thanks.
