My Fortinet-60 died as we moved our office to a new location.
I went down to BestBuy and bought a Netgear FVS318v3 firewall to take it's place temporarily. We have a new static IP range (according to AT&T) of xx.yy.zzz.184 through xx.yy.zzz.192, where .184 is reserved for the modem, .191 is listed as the gateway and .192 is reserved.
Since I wanted to replace the Fortinet with minimal impact to the rest of my LAN, I changed the local IP address of the FVS318v3 to the IP of the old Fortinet box (192.168.1.254) from it's default of 192.168.0.1 and set it to use a static IP of xx.yy.zzz.185 with a netmask 255.255.255.0 and the gateway set to .191
After rebooting the FVS318v3, its status window tells me that I am succesfully connected to the internet at the expected .185 address with the expected .191 gateway.
But I can't access http://google.com/
by URL or even by IP address, so I don't think the issue is DNS. I tried setting my mask to 255.255.255.248 but the FVS318v3 complains that .191 is a broadcast address if I do that.
The FVS318v3 is configured to allow all outbound traffic, but I only enabled inbound SMTP from Postini so far.
I'm obviously missing something basic here. Any suggestions are welcome.
