Why doesn't this firewall work?

[galilao 2]

Hello:

I tried running this firewall at a restaurant with the IP address of 10.1.10.95, an router address of 10.1.10.1, and a subnet mask of 255.255.255.0, and it doesn't block when the VPN is disconnected. Can anybody tell me what is wrong with it?

Thank you

Hello!

In this case the firewall will not block anything because of the following lines:

sudo ipfw add 05000 allow log ip from 10.0.0.0/8 to any

sudo ipfw add 05100 allow log ip from any to 10.0.0.0/8

which must be replaced in any case with the proper AirVPN IP ranges.

Hello,

What ranges would cover all of the AirVPN servers?

Thank you
