Unanswered Question
Feb 1st, 2009

Hi all. I would like to know what are the major differences between firewall and router since a router can also configure accesslists to protect the internal network. One difference i know is that a router is not stateful hence you need to specify your accesslists clearly for both internal and external interfaces. Pls advise. Thks in advance.

I have this problem too.

Answer-

1) WE can make Security-Level on Firewall,but router can't

2) We can make firewall in multiple context(Virtual Firewall) but router can't

3) We can create SSL VPN on Firewall,but router can't

4) Whenever a packet inspected by Firewall and another packet comes with same contents then firewall didn't check that packet,

  but router checks all packets.(show connections)

5) Firewall works as L2 and L3 both, but router only on L3.

6) Firewall inspects packets on L3 to L7 but router works on L3.

7) Firewall have Failover,router can't

8) Whenever we take trace,then firewall cannot comes on picture,but router always shows as a Hop Count.
