I hope you can help me please.
I have two interfaces, wan and lan. Lan subnet is 10.20.30.0.
I have a bt smart hub 2 that I´m not using anymode so on Unraid so I would like to repurpose that router and all the wifi disk attached a wireless access points within my 10.20.x.x network.
The problem is BT do not allow you to modify the subnet, so I have to stick with the one configured 192.168.1.254. So I have disable the DHCP on this router and connected one of it lan ports to my switch and all the wireless devices are working getting DHCP from OPNsense within the range 10.20.X.X.
But as I can´t change the range on the BT router and the interface ( gui ) is on 192.168.1.254, is there any way I can access from my network on 10.20.X.X to this interface without having to configure for a few minutes one pc in the network to that subnet ? I know is just for a few minutes but I would like to be able to connect to that subnet without touching anything.
@johnpoz Sorry mod, you are right and I have edited my post. I'm not using it forever, I have just installed it to test it on Unraid but I will use pfsense following spaceinvader tutorial for Unraid. Thanks anyway for your help.
