New to Sophos Firewall

lachtt, do you mean transparent mode, not bridged mode? That way you can use your TP link as a wireless access point/router and the DHCP server?

Configuring Sophos XG in bridged mode.

It might be better to use the XG as the router, and the TPlink as the switch/wireless AP

Yes, that's what I want to go with because it is easier to manage. Configuring the fw as the router is my second option. I've watched this video, my only problem is how to create its NAT rule.

Hi lachtt 

When you deploy Sophos Firewall first time comes with the default NAT rule which will allow access to the internet.

Below are screenshots for the same

Please refer to below KBA for specific NAT requirements:

Thanks and Regards
