Greetings Sophos UTM Community,
This is my first post and I'd like to ask a basic question.
We are switching Internet providers for our small business, Cable to Fiber. I have a Sophos SG-210 firewall.
My question is do I modify the existing External (WAN) interface to reflect new ISP IP public address, subnet, and gateway? Or just delete existing, add a new one with the information the ISP provided, and reboot?
Any help provided would be very much appreciated.
