hi guys , i am a network student and this is my situation .,,, i want to connect sonicwall firewall nsa 220 to my xfiinity router and do dhcp through my firewall and wifi traffic going to a Cisco AP (already configure with 2.5 and 5 )connected to my sonicwall ,, so i can start playing with firewall rules, policies etc.... so will be like this Internet>>>Xfinity router>>>sonicwall >>>Ap .

Now,, do i need to put my xfinity router on bridge mode to disable dhcp on my xfinity router???
if , so.. my firewall WAN need to be configure with the router LAN IP gateway (10.0.0.1) or with my public ip ???
my new LAN dhcp pool on my firewall needs to have a diferent subnet like 10.0.1.1 or not ???

Thank you guys , hope you can help me understand this.

Thank you
OK if you are going to play this game, get your own CABLE MODEM! It will do what you want it to do, without the limitations of loosing your configs everytime comcast decides to nuke your network segment!
