I have recently upgraded my Internet connection from 2*2 mbps multilink to 10 Mbps Internet line where RJ45 ethernet input given in Giga ethernet 1 . I have connected my Giga ethernet 2 to my firewall .
I have simply assigned WAN ip on Ethernet 1 and my first avalable ip from public ip pool on ethernet 2 . and the next available ip on firewall WAN port .
Assigned a default route towards WAN ip of my service provider .
Do I need to make any other changes here , Do i need to add any access-list here , as i am new to WAN do let me know with example .
Also let me know do i need to get in touch my service provider in adding any additional configuration .
