ACL issue - All traffic getting block in error

eagletec1
Level 1
Level 1

Hi all,

I'm having difficultly with the below ACL. No matter which interface (dailer or fa) I apply it to all IP traffic gets blocked. I must be missing something as I tried this ACL on 3 different 800 series routers all with the same results. Any help would be greatly appreciated.

I'm testing it from a laptop with the IP of 10.1.3.253 and with the ACL off all traffic flows perfectly.

Louise

When Laptop on VLAN 10, you tested with this configuration?:

IP: 10.1.3.253

Mask: 255.255.255.252

GW: 10.1.3.254

If so there is a mistake:

Hi Louise,

Taken from your posted config:

object-group network QQQ_Management_Group

10.1.3.0 255.255.255.252

so 10.1.3.253 is not part of this subnet

Regards.

Hi Louise,

ACL itself looks fine. Post here full config of router to understand better. What is default gateway for laptop?

Abzal

Best regards,

Hi Abzal,

Thanks for your time. Router running config below.

The G/W is 10.1.3.254 (IP of Vlan10), I've also tried changing the G/W on the laptop to 192.168.5.251 (IP of Vlan2) but still no traffic when the ACL is attached to the interface, however both gateways work perfectly with no ACL. The basic setup is restricted users on networks 192.168.0.0/24 (only some users to be restricted), 192.168.2.0/24 (all users), 192.168.3.0/24 (all users) and 192.168.6.254 (all users). The users are to have email access all the time but only web services between 7pm - 10pm hence the time range. This 800 (888-K9) series router is one of three routers all connecting back to Vlan 2 (195.168.5.0/24) which in turn connects to the company gateway 192.168.0.254/24. All the networks that are to have restricted traffic connect to these three routers before being forwarded to the company gateway.

Ok, thank you for requested info. Now how your network is organized. How is your network getting access to the Internet?

What is gateway for it? Is it Vlan2 or ATM0.1? I cannot understand it. On which VLAN your testing laptop is?

Diagram of network topolgy will be very useful.

When Laptop on VLAN 10, you tested with this configuration?:

IP: 10.1.3.253

Mask: 255.255.255.252

GW: 10.1.3.254

If so there is a mistake:

object-group network QQQ_Management_Group

description QQQ Management users unrestricted

range 192.168.0.1 192.168.0.25

range 192.168.0.200 192.168.0.254

192.168.1.0 255.255.255.0

192.168.4.0 255.255.255.0

192.168.5.0 255.255.255.0

192.168.7.0 255.255.255.0

192.168.8.0 255.255.255.0

192.168.10.0 255.255.255.0

10.1.1.0 255.255.255.252

10.1.2.0 255.255.255.252

10.1.3.0 255.255.255.252  --> it should be 10.1.3.252 255.255.255.252

10.1.4.0 255.255.255.252

Thanks guys, this was driving me crazy, such a small simple mistake. That’s why it always pays to get a third person to look at your work. Thanks again

Hi Louise,

Taken from your posted config:

object-group network QQQ_Management_Group

10.1.3.0 255.255.255.252

so 10.1.3.253 is not part of this subnet

Regards.

Alain
