| Unsecured Wireless Network Using External IP I poked around these Forums and couldn't find exactly what I was looking for, so here goes...
I am setting up a public (unsecured) wireless network at our office for students to use.
I have a DSL modem (Bridge Mode) that is passing everything to a firewall (office LAN) and to an additional wireless router via the modem's built in switch.
I have assigned one external static IP to the firewall and another external IP to the wireless router. Both the firewall and the wireless router are set to utilize the same external subnet mask and gateway.
The firewall is the DHCP server for the office (192.168.X.X) and the wireless router is the DHCP server for the public (unsecured) network (10.1.X.X).
My question is how secure is my office network from anyone logging in to the (unsecured) network? |

You should not do it this way, what you have described is double NAT.
What you should look into is...
Internet > DSL Modem > Switch >
then assign 1 static IP from the ISP for your office router
and 1 static IP from the ISP for your open wireless router
or...
Internet > DSL Modem >
assign 1 static IP from the ISP for your office router
off the first router's DMZ port; connect your open wireless router, using a different IP range than your internal LAN range |
