hi!

can anyone help to check why is it my access lists not functioning when i tried to applied both access-lists listed below(fa0/0 and fa0/0.3), whereas if i just applied the access-list on interface fa0/0 inbound(as configured below) it functioning well. The 10.71.9.88 and 10.71.9.93 are able to access .10 subnet and the two .12 hosts. All other .9 host are not able to access any ohter subnet except that two .12 hosts.

The problem came when i tried to apply the access-list listed below on fa0/0.3. It causes, the access-list on fa0/0 not functioning as well. Anyone can pls check on that and correct me. Thks!

Requirements

=============

1) .9 subnet are able to access only 10.71.12.65 and 10.71.12.68 subnet except host .9.93 and .9.88 whereby there can access .10 and .11 subnet

2) .10 vlan can only access 10.71.12.66 and 10.71.12.68. It's restricted from accessing .9, .11 and all other subnets.

fa0/0 - .9 vlan inbound

=========================

access-list 111 permit ip 10.71.9.0 0.0.0.255 host 10.71.12.65

access-list 111 permit ip 10.71.9.0 0.0.0.255 host 10.71.12.68

access-list 111 permit ip host 10.71.9.93 10.71.10.0 0.0.0.255

access-list 111 permit ip host 10.71.9.88 10.71.10.0 0.0.0.255

access-list 111 deny ip any any

fa0/0.3 - .10 vlan inbound

I guess, this was discussed previously in another post of yours. Can you paste your show run as well ?

hi! Below is the sh run output. I just replaced the access-list 12 with

===================================================

with access-list 111 permit ip host 10.71.9.93 any

access-list 111 permit ip host 10.71.9.130 any

access-list 111 permit ip 10.71.9.0 0.0.0.255 host 10.71.12.65

access-list 111 permit ip 10.71.9.0 0.0.0.255 host 10.71.12.64

access-list 111 permit ip 10.71.9.0 0.0.0.255 host 10.71.12.68

access-list 111 permit ip 10.71.9.0 0.0.0.255 host 10.71.12.69

access-list 111 permit ip 10.71.9.0 0.0.0.255 host 10.71.12.70

====================================================

and replaced access list 10 with the following

==================================================

access-list 113 permit ip 10.71.10.0 0.0.0.255 host 10.71.12.66

access-list 113 permit ip 10.71.10.0 0.0.0.255 host 10.71.12.68

access-list 113 permit ip 10.71.10.0 0.0.0.255 host 10.71.12.64

access-list 113 permit ip 10.71.10.0 0.0.0.255 host 10.71.12.65

access-list 113 permit ip 10.71.10.0 0.0.0.255 host 10.71.12.70

The fact that you're sub-interfacing and have an address on the physical interface itself doesn't seem right to me.....

I believe, and I could be wrong, that you shouldn't have an ip address on fa0/0 if you're subinterfacing... If you were to move that segment from fa0/0 to something like fa0/0.5 and try adding the acccess list again it may work... right now you're not tagging that segment (10.71.9.254/24) with dot1q info

I'd be curious to see if this fixes your prob....

hi!

I've tested on 2 of the interfaces except fa0/0, it work fine for the statement where the source ip is a range of ip eg. 10.71.10.0 0.0.0.255, but when i try putting in only one host for the source. That source statement doesn't work.

any idea?

hi!

Anyone here can help to solve my problem above? Thanks in advance
