HI team,
When Firewall is capable of doing routing and switching for a SOHO, why we need a router. Is there any specific advantage to use router alomng with Firewall.
Please clarify.
Thanks & Regards,

Hi,
Here are a few reasons why you need a router:
- The firewall only has ethernet ports. However your Internet or WAN link may come as an ADSL or Frame Relay connection. In this case you will need a router to terminate the connection.
- Firewalls are weak at policy based routing. A router is better suited for this purpose.
- Firewalls are not MPLS aware. If you want full MPLS functionality you will need a router.
- ASA firewalls do not support BGP as a routing protocol. You will need a router for this type of connectivity.
Cheers
