I'd like to check my thinking here, please. I've read other posts but just got more confused!
Network DHCP uses 192.168.11.100-.200 range.
Linksys WRT54G would be assigned IP in the 192.168.11.xx range which is a necessary step, isn't it, to gain access to the network T1 via the usual network jack? Static IP would help me track it.
I would then assign Linksys router its own DHCP pool away from that subnet, like 192.168.54.x.
Would this then give guests who log on to the Linksys their Internet access without them crossing into my business domain?
Would it matter if they connected to that Linksys wirelessly or via an Ethernet port on the Linksys meaning I believe the Linksys assigns the non-network-range IP for both types of connection?
If set up properly, then in-company users would have to use VPN over that Internet connection to actually connect to the business domain, yes?
I'm changing Linksys admin name and password, using WPA with complex password. Am I over-simplifying this?
Once done, I'd repeat this setup for two other LinkSys devices by establishing their own network IP then set those devices' DHCP pools away from the network subnet and the other Linksys devices.
