You can block ip address/ranges and ports using access lists on a router.

Cisco have there own firewall called PIX that runs on dedicated hardware.

I have a similar question, can it autamatically detect if there is a Dos Attack or we have to find the IP and block manually.

I think that would be down to your network monitoring tools to highlight those issues for normal routers.

Here's a cisco doc on dos attacks

Cisco PIX firewalls can automatically detect DOS attacks and deny them. But in the case of a router you need to have the ACLs in place to be safe

Or a list available for contacts?

We are an investment bank looking to invest in and or acquire such firms.
