[SOLVED] OPNsense 17.7.11-amd64 New Installation

[hjint]

Goodday,
I'm completely new to OPNsense and from the write-ups on the internet, I decided to go the OPNsense firewall route above other packages.

I need setup assistance as I can not connect to the internet when OPNsense is in control

My current setup is:

Router0 - 192.168.10.1 - 3G Failover Router
Router1 - 192.168.10.2 - DSL Rouer
Opnsense.localdomain - WAN - DHCP - 192.168.10.18 (Connected to Router1)
Opnsense.localdomain - LAN - Static - 192.168.10.4 (Connected to Switch)
Ethernet Switch

While the switch is connected to Router1, I can access Opnsense.localdomain via GUI and the internet. When the switch is disconnected from Router1, I can not access the internet or Opnsense.localdomain. Somewhere I'm missing a setting but can't figure out where.

I have attached screen shots of the Dashboard, interfaces, NAT, firewall rules and log files.

Assistance will be highly appreciated

If you have the same subnet on the LAN and the WAN side, your OPNsense is not a router; it's a bridge.

I would either set a different LAN subnet, or use this configuration: https://wiki.opnsense.org/manual/how-tos/transparent_bridge.html

Thanks Bart, changed router1 from x.10.2 to x.1.2 and solved the problem
