And, if you do not do option 5:
6. Confirm that the WinGate server has detected your network cards / modem correctly for firewall and connectivity purposes. The network card / modem pointing towards the internet should be set as EXTERNAL in WinGate, and the network card pointing towards your LAN is marked as INTERNAL. FYI: If you only have one network card, and it has a default gateway set to a hardware router with a firewall, then you can set it as INTERNAL in WinGate; WinGate can do single network card NAT.
7. Confirm the Webserver has a default gateway set. To check for NAT and DNS connectivity you could do the following; the format below is domain name, and then the equivalent ip address:
(Windows) Start menu --> Run --> cmd --> ping
www.wingate.com
(Windows) Start menu --> Run --> cmd --> ping 210.55.214.36
(Windows) Start menu --> Run --> cmd --> ping
www.google.com
(Windows) Start menu --> Run --> cmd --> ping 66.102.7.99
8. On the Web Server, the Windows Firewall is best disabled in the Windows Services for the sake of testing if you deem it safe, and any other security suites.
Correction from last post:
3. Confirm you used the "NOT" when you created the criterion **as well as "Begins with"**
This criterion is NOT met if Client IP address BEGINS WITH 192.168.0.*
*and you would not need the * at the end of 192.168.0. - I will edit that other post.
**and I presume you put your subnet in.
