Hello! good morning!

 

As Seb said you have to configure NAT, following the steps he gave you in order to built your NAT ACL, also your outsite interface have to be the ATM interface and vlan 1 has to be the inside. One thing I need to understad is why your DNS is 10.249.111.1? You have to use the IP of your internal DNS and an external DNS, in case you don't have internal DNS so use 2 external DNSs: dns-server 4.2.2.2 8.8.8.8
