multiple Subnet in Sophos XG210

Either set up a second LAN interface with an address in that subnet, say 192.168.3.1/24 or if there is another device between the subnets set up a static route on the XG directing traffic for the new subnet to the router in between.

If you don't have any spare interfaces you can add an alias on an existing LAN interface and will end up with a .0 subinterface.

Hi kmmedical software 

Please watch this video for How To: Adding And Configuring Interfaces in Sophos XG.

Thanks for your information,

My scenario I need to communicate with two subnet machines

192.168.1.0 /24  - Management Team, All team & Domain 

192.168.3.0 / 24 - Accounts team 

Accounts Team, Management Team  & Domain need in & out communication.

That would be easy. You will need to create a Firewall rule for the Zone and Network between which you want to allow traffic. So if you want two-way communications between 192.168.1.0/24 & 192.168.3.0/24, create a Firewall rule with Source and Destination Zones as respective zones for the subnets and add Source and Destination Networks as the ones you want to allow communications between.
