I was wondering if I use the switch option on dd-wrt. If I have the firewall activated. Will all of the pc attached to the router have that firewall? If I have a static DNS put down. Will they also use that DNS?
I have been running T-mobile ISP, and the modem/router does not have anything to edit. So I am not sure if it has a firewall. I also want to use a different DNS. However it does have DHCP

It would help to know what devices you plan on or are using, and if you are running DD-WRT, on what router and what version of DD-WRT you're running.

Generally speaking, if you add a wireless router in-between the ISP and your devices (regardless if that connection is wired or WiFi), you will have a NAT, which is a good security measure to start with, and on top of that you can enable and configure (the basic part of) the embedded Firewall, and if you want to secure it even further, you can tweak the iptables. That goes for the DNS tweakings too (for instance I use an adblock for all my devices).
And this is a general response to a general question. If you want more details, please consider moving this discussion to the related device forum section. _________________ If you want support, please read first the announcements and forum rules.

I don't think that the static DNS addresses will pass to client in switch or wired AP modes. I've never messed with that, and you generally don't leave the firewall enabled in switch or wired AP modes. _________________ "Life is but a fleeting moment, a vapor that vanishes quickly; All is vanity"

My issue is that I do not think the T-mobile modem/router has a firewall. It also does not have an option to change the DNS. If I change this router to a switch. Is their a way to test and see if I have both working? If I have both enabled.
