One subnet can't access another subnet

Hi.

I'm obviously doing something wrong and it's driving me mad

Sophos UTM. 3 NICs. 1 is the external (internet) NIC

2 is 192.168.0.1/24

3 is 192.168.2.1/24 off of this is a Ubiquiti Dream Machine Pro (UDM) which has 192.168.1.1/24 coming out, with cameras and WiFi clients

I can access the UDM via domain name and configure it and view cameras

But I canNOT access the UDM by IP address - 192.168.1.1

I have set a F/W rule: My machine IP as a Host -> Any IP4 -> 192.168.1.1/24 Network (Allow), and log access, and I can see it allowing it through, but the browser times out and never connects. But even without the F/W I CAN connect using the domain name

Any clues?

  • Thank you everyone. That does indeed work

    I wasn't understanding the Ubiquiti UDM and had to also open "WAN Local" to traffic coming though the Sophos UTM, that then immediately allowed me to see the UDM network (192.168.1.1) coming through the 192.168.2.1 network (Purple Network) on Sophos, from my 192.168.0.1 Green Network

    Brilliant!
