I have a store that is running DSL(Windstream single port modem in bridge mode) through a Sonicwall tz-170 and I'm needing to put a separate Lan with a different IP scheme inside the store and I've never done this before. The internal IP addresses currently are static on a 18.104.22.168 network and I'm wanting to set up another network and have a VPN on 192.168.14.0. Can someone tell me step by step how to configure the tz-170 for this or give me some ideas? I've heard I could use the Opt port or create some kind of ARP entry but I need some more detail. The default gateway would be 192.168.14.1 for the 2nd network and I want to connect to a 192.168.200.0 network on the other end of the VPN. Let me know if you need further details. If this can't be done I'm wondering if I could just setup a DSL modem that has multiple ports such as a Netopia/Cayman 3347 and use one port for the Sonicwall side and use another port for a Watchguard Firebox that I have for the secondary network if need be.
