Setting up Web Filtering on Cisco881 sec K9 router using CCP.
At the moment every user on the domain got blocked by the rule that i set up on the Web Filter (just using the wizard and choose default category). What i want is to separate users so that specific user can have full access while other user get filtered by the category.
And Yes I want to configure this using CCP.
I have come across articles mentioning that URL Filtering can be implemented by using ASA 5505 with URL Filtering Servers. But Websense and other Web Filtering Servers are paid ones ? Are there any free solutions available ? What exactly is N2H2 ? The reason is I don 't want to increase the CPU utilization of ASA by implementing URL filtering within the device. If I have around 30 nodes which connects to the internet via a 2Mbps line through ASA 5505 and if I want to block around say 10 or 15 URLs , will it increase CU utilization beyond permissible limits ? Currently the CPU Utilization is around 10 - 15 . Here's the infrastructure setup .

We have a Cisco 4400 series WLAN controller.When I go to the clients and view who is connected; I can also filter it. However it only lets me filter by mac address, ap, wlan profile, etc.
It does not have IP filtering. Is there a way to filter using IP? Basically I want to find a particular client with a certain IP that's connected to our WLAN.Also how do we block the client? If we deemed that person should not get access.
I just upgraded to the Belkin N750 DB router from the version just below it and couldn't get the wireless card (Ralink RT2760) in my daughter's dual-boot WinXP/Ubuntu 10.04 to connect to the WPA security setting (WEP only) on the Ubuntu side. There is an updated driver, but it's way above my Linux skill set, so instead I just disabled security completely, and used the MAC Address filtering to add all of our household devices.This solved her connection problem, but I am wondering if there is any danger to this method that I might not have considered

I have a 2621 with a WIC-1ADSL that connects to my ISP. Since the 2621 has 2 ethernet ports, I wanted to setup a network on the second ethernet port for testing things such as VPN into my network via my ASA5505. I have a DHCP pool set on the particular network but cannot get a client to get an address from the router. I think I might have an ACL that is blocking or need an ACL to allow bootp on the interface. Here is the config:

When I try to get an ip address from a client, I never receive one. But when I issue dhcp server statistics, I can see packets hitting the interface:

Could URL FIltering be implemented on Cisco ASA 5505-BUN-k9?i mean to block certain websites, like facebook, youtube, to block certain download files like .exe, .com .bat etc....Is there any extra license needed for this, or it could be done with the simple IOS ASA5505-bun-k9?

I have two WAP 321 devices set up in our building they are on the same subnet with the same SSID and are using the WDS bridge mode. My question is, if i enable mac-address filtering on one of these devices will this infomation be passed to the other bridged device? or would the allow/deny list need to be populated manually on each device?
View 2 Replies View RelatedI have recently upgraded my company's network significantly, and in the process removed our Cisco edge routers and firewalls (gasp!), and replaced them with another vendor who gave a better price point for the router.However, i was only able to get ONE edge router, whereas before I had two, so I want to recycle one of my old 2921's as a cold standby (in case the brown sticky stuff hits the rotating air distribution blades, and $other-vendor router dies).Trouble is, the 2921 does not, I believe, have sufficient system resources to take the full routing table we're getting from our two ISP's.What I would like to ask is people's thoughts on the best method for me to configure the BGP setup on the 2921 to do the following:
-Accept the default route from each ISP and discard *everything* else in the route table
-Modify our advertisement (ad prepend) out the "secondary" ISP to reduce the priority of traffic coming in over this link.
-Configure the OUTBOUND priorities so that the "primary" link is used by preference for outgoing traffic (which will effectively shut down the secondary link for outbound traffic
I am trying to block clients based on MAC addresses connecting to our Wireless Guest network.
My scenario is: We have 2 interfaces (corporate and a guest). Users are connecting to our guest network after they have automatically connected to our corporate network and logged into Windows. When they realise that things are not quite working in the way they want (access to servers etc...), they reboot and then find they cannot logon to the laptop at all. This is because the laptop has automatically rejoined the guest network and has no access to AD. I then have to locally logon to the laptop and remove the guest network.

Hardware: WLC5508, Software Version 7.3
So far I’ve tried enabling MAC Filtering under “Security -> AAA -> MAC Filtering”, but found out that it’s a white list. The opposite of what I’m trying to achieve, but I like the fact you can link it to a specific interface.
I’m just looking at the “Disabled Clients” again under “Security -> AAA ->”, but think this is more a total ban as I cannot see a method at attaching it to an individual interface. I'm kindda stuck and my good old friend Google is not yielding great results.
I’m not by any means a wireless expert, so there is probably a better method. I would prefer to use the controller as a way of achieving this, but if you think I’m wasting my time and should be looking at a Windows Group Policy method then I’ll go with that?

Any upto date reference for setting up the ACS v 5.3 for mac filtering via built in radius with wireless lan controllers?
all I seem to find is this old document - which uses the user database.
the ACS 5.3 has host store, which seems like the logical place to setup mac address information

There is a feature in WLC 7.3.0 like Configuring a Fallback Policy with MAC Filtering and Web Authentication .We have an option to configure mac filtering and we can create a policy that if mac filtering failes redirect it to web authentication
Here i am using mac filtering is only for my mac caching process. But when i tried this its not working.
My mac address is not there in the WLC, so it should prompt me the web authentication page.But its not happening. As long as my mac is not there in the table, i am not able to connect to the SSID.
So what is this feature (Configuring a Fallback Policy with MAC Filtering and Web Authentication) meant for ?

I've a new Dlink DIR-632. All ports snif from outside are answering stealth by default. And the port forwarding feature works good.The problem is that I would like to allow a trusted net IP to reach my computer, whatever the request may be (whatever tcp/udp and on any ports). A kind of DMZ just for a precise IP. I tried the inbound filter feature. I've choosen allow, and I've put the remote IP start and end the same IP. It has been added correctly to the list. However, this IP still doesn't seem to be able to access to my computer on any port unless it tries on an already forwarded port.
