Cisco 1841 Bridge Mode ACLs
Posted on 2013-12-16
Hello Experts - I am attempting to use a Cisco 1841 router in bridged mode. I'd like to use its ACL features to limit access to a set of predefined IP address ranges. I have a 50mb FIOS line plugged into the FE0/0 port and a D-Link 605L home router plugged into the 1841's FE0/1 port, pass through is working fine. I then setup a series of extended access control lists with the ranges of the hosts I want people to be able to access:
access-list 110 permit ip x.x.x.x any
Unfortunately this doesn't seem to be working as I still have access to things like VPN which should be blocked. I'm setting this up after entering confg t but I am not under a particular interface and am wondering if (and how) the ACL needs to be applied to the bridge group I created. My assumption is that the router would block requests to anything other than the hosts I defined in the ACLs but I don't know if that is correct. I'd appreciate any general advice on things I could be doing wrong or if the concept of what I'm trying to do is sound, thanks!
