My current physical configuration:
- 1 Hyper-V (Server 2016) host
- 4 physical NIC’s: 1 directly connected to the modem (PPPoE connection), 3 NIC’s connected to 3 WiFI routers (these 2 routers are in Access Point operational mode, therefore NAT and DHCP are disabled on these devices).
- 5 virtual switches created: 4 External (with assigned NIC) and one Internal
Current VyOS configuration:
ppp0 - managed to setup successfully (I receive ping reply from www.yahoo.com)
eth0 - in which the cable from the modem is plugged in has no IP Address (physical WAN port, I guess)
eth1 - cable from WiFi AP 1 - 192.168.1.10
eth2 - cable from WiFi AP 2 - 192.168.1.20
eth3 - cable from WiFi AP 3 - 192.168.1.30
I’ve managed to install VyOS on a VM. The purpose of this VM is to be the facing Router to the Internet (ISP Modem -> VyOS Router -> 3 WiFi AP’s -> Client devices).
- Can I assign 192.168.1.1 to eth0 and act as a DHCP server and DNS forwarder (from ppp0)?
- When I configure NAT, do I need to NAT to interface ppp0 with source 192.168.1.0/24? And also, is it safe?
- If I can NAT to ppp0, the Firewall rules (packages from the OUTSIDE), should be only applied to ppp0 interface?
Thanks in advance
