Proper ACL for guest wireless traffic
Info:
Aruba 3810
Vlans 801,802,803
Vlan 802 is our guest wireless subnet. I need to allow it to pull DNS from 801, pull dhcp from the switch, but not have any other access to 801 or 802 and go directly to the Internet, allowing all protocols. I only have access to the switch and am unable to test, so need to be sure I have things set up correctly. Does this accomplish what I need, based on the included config?
ip access-list extended "Guest Vlan Access"
10 permit tcp 10.10.0.0 0.0.255.255 eq 53 172.17.0.0 0.0.255.255 log
20 deny ip 10.10.0.0 0.0.255.255 172.17.0.0 0.0.255.255 log
30 deny ip 10.10.0.0 0.0.255.255 10.13.0.0 0.0.255.255 log
40 permit ip 10.10.0.0 0.0.255.255 0.0.0.0 255.255.255.255
