I have a Cisco 800 series router coming into my office. I recently purchased a Firebox X700 to setup here for firewall protection. Our subnet mask is 255.255.255.0 on all the PCs and our DHCP range is from 10.0.0.10-10.0.0.254. I'm currently setting up the X700 and its asking for a Trusted IP address, along with a secondary IP address. I'm assuming that in the Trusted IP, i'm suppose to put a static address within the range of our network. I'm not sure what to put in the secondary IP. My second question is, am i going to have to change my configuration in my Cisco in order for me to have a VPN. I'm assuming I will so i can open up certain ports or IPs to come through, however I have no cisco experience, classes don't start until September lol.
