router/firewall

[ssahl]

If you pay for T1 internet (or better) and pay for a router, does that router have a firewall too?

Yes. The network address translation necessary for routers to work automatically creates a firewall.

There are more to firewalls than just NAT - the router may or may not have more advanced features.

Definitely true, but even if you only have NAT you are effectively firewalled because all unsolicited connections are blocked.
