Question : DIFFERENCE BETWEEN STANDARD & EXTENDED ACL'S QUERY

im wishing to add my master dc to the network on a basic rip/ver1 network, but not until ive clarified below:  according to my book it states: can anyone give me advice because im confused!!!!

rules:
1. standard acl's - should be added on the router closest to the destination
2. extended acl's - should be added on the router closest to the source

my config below shows that both standard & extended acl's are both on my vista router being the source.  ive also carried out an extended ping command and 10/net cannot ping 192.168.3.2 and this i agree, but if the rules are as above why is the standard acl working as my acl's are at the source, or are the rules the wrong way round?

Answer : DIFFERENCE BETWEEN STANDARD & EXTENDED ACL'S QUERY

Those aren't actually "rules". They are more like guidelines. The ACL is placed where it will accomplish the goals.
