Access List question

michael_knight

this is a real simple question I just confused myself. In access list statement are they to from or from to statement? For example

access-list 173 permit ip host 162.119.172.112 host 162.119.163.11

Is that perming ip from host 112 to 11 of from host 11 to host 112?

First is source second is destination.

But keep in mind that source and destination is relative to direction of the traffic flow.

Relative to the source and destination address in the IP header of course

michael_knight,

For an access list # of 173, what type of access list is this?

Standard
Extended

ixg123

Standard ACLs are numbered 0-99 and 1300-1999 ... so it's a pretty safe bet that it's not a standard ACL!

Another hint would be that a standard ACL can filter only on souce host/network. If the ACL is filtering by anything else then it would be an extended ACL.
