Cisco ASA 5505 External IP change

We had AT&T internet and just had Comcast installed. We have a static ip address and was wondering if all I need to do it change the "outside" connection configuration in the GUI over from the PPOE setting, to the "static ip" radio button then enter in the ip information.

Thank you.

Your new IP address, subnet mask, gateway, route needs to be updated in the config. ASDM is alright, if you're not comfortable with CLI.

Also, I've seen cases where the firewall would need a restart, to get it to work after saving the configuration.

When you say " route needs to be updated in the config" What do you mean?

Thanks.

Do you have a command that states:

route outside 0.0.0.0 0.0.0.0 <Gateway's IP> 1

?

<Gateway's IP> could be one IP higher than your outside interface's IP.

Also, please check if you have these:

global (outside) 1 interface
nat (inside) 1 0.0.0.0 0.0.0.0

ok I see the tab that reads ip address and route settings. That has "obtain from PPoE right now. So I just select the  " specify an IP address" radio button and enter in the gateway IP over there?
