Hello all of you...
I'm a student and new to this list...
I have to study all kinds of firewall in the market.I heard a lot about
security routers (auditing,alerting,...), application gateways, proxy...
My question is simple: althought routers works at layer 3 and can deny
access with conditions like source and destination address, port number,
interface, direction...is a router-firewall really unsecure? If the access
lists are really safe, are there attacks (like pinging) that routers can't
support? If there are, please, give me examples...
Regards.
