    Hi all,

    I am a bit confused with alias definition.

     

    If i have a firewall policy: any any svc-icmp permit

     

    Who is the alias?
    - network source
    - network destination
    - network service

    An alias typically refers to a variable that represents an ip address or network:

    In your example, the alias would be "any" because it would represent any network traffic.

    Hi, there is a couple of Aliases. A network service alias :

     

    A network service alias defines a TCP, UDP or IP protocol and a list or range of ports supported by that service. When you create a network service alias, you can use that alias when specifying the network service for multiple session ACLs.

     

    (host)(config) #netservice <name> <protocol>|tcp|udp {list <port>,<port>}|{<port> [<port>]} [ALG <service>

     

    Or a Network Alias which can be either your source or destination subnet. So this is a network IP or IP ranges.

     

    (host)(config) #netdestination “Internal Network”

    network 10.0.0.0 255.0.0.0
network 172.16.0.0 255.255.0.0
