I do some IT work for an auto body shop. I must separate some devices onto a router and place them on a different subnet. The two subnets are 192.168.1.0/24 and 192.168.2.0/24. No firewall has been implemented yet. I am able to communicate from the devices on the 192.168.2.0/24 to 192.168.1.0/24 and vice versa.
Since it will only be a few devices they are all assigned static IPs. I do have them pointing to the DNS server on 192.168.1.2 and can ping to it. Do I need a DNS server specially on 192.68.2.0 network? I did temporarily enable DHCP on R2 and was still able to ping to R1 but no internet.
The two devices used are TP-Link Archer C9 for the 192.168.1.0/24 (main network) and TP-Link ER605 for the other network. Before there was a switch in place of the ER605, and the devices connected to the switch got the internet fine. So, it's some setting in the ER605. Unsure of what though.
Does the WAN port matter at all for this? Those really are just for direct connection with the ISP gear I thought. Do I need to implement NAT? There is an option for one-to-one NAT, would I just change all the addressed over to 192.168.1.0/24 network?
It's also the ER605 itself that does not have access to the internet. I was unable to run ping to the internet even with DNS showing the translated IP and pings to IP addresses failed as well.
