Hi Everybody:
I had read the discussion and I thought: Well, Let's forget the firewalls
and let's start to use the IOS Firewall Feature Set in our routers, or
simply use the ACL's to mantain our networks secure!! :-). This is enough.
Now seriously speaking, Does anyone knows a case of a router with ACL's
penetrated, and if this could be avoided with a traditional firewall (like
Gauntet, Firewall-1 or Sonicwall)
Regards from Chile
