Cisco – Create an Access List in ‘Router-on-a-Stick’

aclciscovlan

I am trying to create a access in a "router-on-a-stick" which only allow VLAN 62 to communicate with a server on another VLAN and no other hosts in the other VLANs can get to VLAN 62.To be clear, my VLAN 62 is a VLAN for webcams and my server is the registration server. I have try doing standard and extended acl but it just wouldn't work. Can anyone help me out ?
P.s: I have one question, too. In standard acl, is it true that the "deny part" have to be on top of the "permit part". Sorry for my bad English.

version 15.1
no service timestamps log datetime msec
no service timestamps debug datetime msec
no service password-encryption

To allow devices on VLAN 62 to talk to VLAN2, and nothing else.

access-list 162 permit ip 192.168.6.128 0.0.0.63 192.168.6.0 0.0.0.63
access-list 162 permit udp any any eq bootps
access-list 163 permit ip 192.168.6.0 0.0.0.63 192.168.6.128 0.0.0.63
access-list 163 permit udp any any eq bootpc
interface GigabitEthernet0/0.62
ip access-group 162 in
ip access-group 163 out

Note the wildcard mask 0.0.0.63 in the ACLs. Also, "deny any any" is implicit at the end of every ACL. If you explicitly state it, it goes at the end.
