How do I my switch, firewall, and DSL to work together?

2 wire firewall? what ever that is your going to need a gateway of some kind, you could just put to nics in one computer and run internet connection sharing off of it. but that way is a pain. the best option is to buy a dsl router, they all come with firewalls built in.

i went to the tomshardware forums and all i got was this lousy signature.

Does your firewall do NAT? If it doesn't, you need to buy a gateway. If it does do NAT, and (hopefully) DHCP:

Plug ethernet from DSL modem to firewall.
If you have an UPLINK port on your switch{
Plug regular Cat-5 from Firewall to uplink. PLug the comps into the switch. Configure firewall to serve as NAT host, and DHCP server.
}
else {
PLug a crossover ethernet cable from Port 1 of your switch to the firewall. Configure DHCP and NAT as above.
}

Good luck.

Another interesting trick I learned is some DSL IPS do a login protocal. If you use a router (the easiest route) make sure you don't have WinPoET or similar software installed.

Now that's something those helpful tech folk won't tell you - they want you to buy their stuff...

To expand on what CStew77 is saying.

If verizon is using a ppp connection(pppoe or pppoa), then either the modem they are using has the username/password programmed into it or they have supplied you with software like ethernet 300 or winpoet to do pppoe or pppoa authentication.

If that is the case, see if your 2 wire firewall has a pppoe option for you to supply the username and password.

If verizon is running bridging which I doubt then theres probally no need as most bridging setups ive seen dont bother with authentication.
