Network Attack Blocked

Today I received two alarms from Smart Home Manager saying it blocked two network attacks. The IPs is blocked were 80.66.66.145 and 185.242.226.49. It says “We blocked a scanning attack and recommends I create a unique password.

These two attacks come a day after ATT made a change in the IP Passthrough setting on my BG320.

 The other day I reported I was having some lag in an online PC game. So, the rep setup a default server under IP Passthrough and used my gaming PC’s IP address for IP passthrough. He said it would allow Open NAT just on my gaming PC. And could help improve the lag I have in this game.

 I have since turned default server to Off. it wouldn’t let me deleted my pc IP but it is Off. just to be sure, I also went to advanced firewall and set as default. Nothing should have been changed there but just double checking. 

 should I be good now? Or should I still he worried? 

thanks
