ok
i am posting the answer i know most of u are beginer only
so it will very difficult to understand
i will try to make it easy
A firewall is a device whic act as a gateway betweeen
insdie (lan) and outsie(internet).
so bacicaly firewall is security device.
priviously cisco introduce firewall with the name or pix in
series of 501 502 and all
now this is out of market and we are using cisco asa beause
this asa have much more fetaure then pix
now basics of asa
a asa have basicaly 4 interface
1 insie
2 outsdie
3 dmz
4 mangment
it colud have more then 4 inerface also
so what ever is name of the interface it is default.you can
change it by urs name also
some basics command for firwall-:
ASA(CONFIG)#INTERFACE FA0/1
#NAMEIF INSIDE
#SECURITY-LEVEL 100
NOTE- SECURITY-LEVEL WHAT IS THIS? THIS IS THE LEVEL
WHICH DEFINED HOW MUCH A INTERFACE IS RELIABLE.
SECURITY-LEVEL IS DIFINED 1 TO 100
100 IS A VERY SECUR LEVEL
0 IS LESS SECURE
ASA(CONFIG)#IP ADDRESS 192.168.100.1 255.255.255.0
ASA(CONFIG)#NO SHUT
ASA(CONFIG)DUPLEX FULL
ASA(CONFIG)#SPEED AUTO
SIMILARLY U CAN CONFIGUR THR INTERFASE
