ACL on Switch 3550 (with routing enabled)

MUKADI Pierre

Hi there

Can you help me?

I'm configuring acl on my cisco but it doesn't work.

My network looks like this :

Internet  <--->(eth0) MikrotikRouter (eth1) <--->(fa0/1) Cisco switch (3550) (int vlanX) <---> Internal VLANs

1. On my MIKROTIK :

- I have a public IP and NAT configure

- I have RIP v2 configure on the internal interace (eth1) : 172.16.1.1

- I have some rule that block microsoft downloading site, social network, steaming, etc.

2. On my Cisco switch (3550):

- I have Routing enabled, RIP v2 enabled, networks (To and From Mikrotik network: 172.16.1.1, VLANs networks:192,168.0.0/24) configured, ...

My problem is :

Without ACL, the internet is working.

But when I configure the ACL, internet does not pass.

NB : Ping and DNS work : ping google.fr is ok

         But Internet (on browser) does not work. Telnet on port 80, etc. does not work.

MY ACL is :

If I understood your topology correctly I believe what you want is "ip access-group 111 in", not "out"...
