[dhanikonda]

Dear experts,

iam facing a big problem that is

Access Rule1: 172.16.0.34 IP should be allowed through LAN.

Access Rule2: Allowed network traffic 172.16.2.100 - 172.16.2. 254

Except the above network range no other traffic should be allowed through our LAN (LAN to WAN).

How can i do this .If any body helps i will be very greatfull to him.

Srini...

0.0.0.3 is wildcard mask in the statement.

It implies tat this acl will permit ip's from 172.16.2.100 till 172.16.2.100.3.(4 hosts)

Its a way of allowing a range of IP addresses.

Zero's in the first 3 octet means the source address should match the 172.16.2.100 exactly.
