Question

comcast gateway - netgear firewall - sbs 2003 configuration can get out but not in

Asked by: midwestdev

I have the following configuration:

Comcast modem/gateway:
LAN:192.168.1.1
        255.255.255.0
DHCP:Off
Firewall: 1-1-NAT enabled
             static ip 1 mapped to 192.168.16.2 sbs 2003 server
            static ip 2 mapped to 192.168.16.3 web server
           static ip3 mapped to                    .4 terminal server


Netgear Prosafe VPN Firewall
Wan1
IP: 192.168.1.2
sub:  255.255.255.0
gate:192.168.1.1
dns 192.168.16.2  sbs 2003
LAN:
IP: 192.168.16.1
sub:255.255.255.0
i opened  ports: 25,80,443,444,4125,1723,3389

I can access the internet fine from within my network and application like logmein works fine.

 BUT I can not access OWA(exchange web access), Outlook  from outside network using HTTP, terminal server or other web server.

I have the netgear as a failsafe with if comcast goes down then wan 2 ATT continues. Can you have  2 firewalls? Does it help? I get hit by people trying to logon my network nightly. I also have TrendMicro on all servers and workstations.

So, what is blocking static Ip request between comcast gateway and netgear firewall?
