Looking for a suitable device for a small network
I have a simple problem, yet require your help.
I need to combine 4 elements into a network:
1. A router provided by my ISP, which holds the Internet connection. Its configuration is very limited - no VLANs, no advanced firewall configuration, no guest Wi-Fi, etc. For the sake of argument, we assume it cannot be replaced.
2. A local network connected through an unmanaged switch. All devices require communication with each other and with the Internet.
3. A single workstation. Requires communication with the local network above (specifically with just one computer in that network), but it must not be connected to the Internet.
4. Guest Wi-Fi access point - the other way around, obviously. Internet access, but no LAN access.
To sum it up, the following communication must be allowed:
1 to 2 and 4
2 to 1 and 3
3 to 2 (or rather a single device in 2)
4 to 1
My question is: which device (a managed switch, I presume) can I buy cheaply (tiny business) in order to make it work as simply as possible?
Everything was working on Zyxel ZyWALL 5, but without an extra router from the ISP (Internet connection was handled by ZyWALL directly). Number 4 was connected to a WLAN port, with firewall allowing WLAN to WAN, but dropping WLAN to LAN. Number 3 was in LAN, but any attempt of communication with WAN from its IP was being dropped. I cannot do that so easily after adding an external router. Also, at this time I need gigabit ethernet.
I will appreciate any and all suggestions.
