Cisco Firewall :: ASA 5505 URL Filtering Using URL Filtering Server?

Feb 7, 2012

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 .

Nodes -->Switches-->ASA 5505-->Internet

Cisco Firewall :: ASA 5520 No Address Available For SVC Connection

Oct 7, 2012

We recently replaced our Cisco 5510 with a 5520. I had the SSL Client VPN working on the 5510, I cannot get it working on the 5520. The IOS version is 8.2(5) and the ASDM version is 6.4.I run through the SSL Client wizard and get everything set up. When I try to get to my outside interface Internet Explorer just comes up with an error. When I try to connect through the Cisco AnyConnect client on my Android it used to come up with a "No address available for SVC connection". After deleting an address pool not even related to my SSL VPN profile I cannot get that far. I just get a "login failed". Even after I create a user with level 15 privilege and assign to my vpn group policy.I still get the "No address available for SVC connection" when I try to connect to the default profile, which doesn't really go anywhere.

Cisco Firewall :: 5520 Static NAT And Same IP Address For Two Interfaces

May 28, 2012

We have a Cisco ASA 5520 and in order to conserve public IP addresses and configuration (possibly) can we use the same public IP address for a static NAT with two different interfaces? Here is an example of what I'm refering too where would be the same public IP address.
-static (inside,Outside)  access-list inside_nat_static_1
-static (production,Outside)  access-list production_nat_static_1

Cisco Firewall :: ASA 5520 Address Translation And Port Forwarding

Oct 31, 2011

I am trying to correctly configure our ASA 5520 and our Mitel Border Gateway in our DMZ.  In the documentation for the Mitel border gateway it wants me to set up 2 external IP's on my ASA one to allow 443 traffice into the MBG, and another for 443 traffic that needs to be forwarded to port 4443 for the MGB in the DMZ.  My problem is I don't know how to do this. the MBG only has one IP, and I need to have 2 different URL's mapped to two different external IP's both externally using port 443, and one of them forwarding to 4443 on the DMZ interface.

Cisco Firewall :: ASA 5520 - Permit Traffic To Inside Via MAC - Address?

Apr 6, 2011

I have a handheld device that will be used for inventory outside of our office. It has 3g capabilities. Is there anyway I can permit traffic from this device from the outside world coming into my network?  I need to open a couple of ports so it can hit the server. But I have no intention to open these ports up to the entire world.  I use an ASA 5520 with a managed router from our provider. I looked around on the Cisco site and the only information I found was for permitting and denying traffic from devices that are within the network.

Cisco Firewall :: 5520 - Multiple Global IP Address Range On ASA Outside I/f

Mar 17, 2011

Got an ASA5520 running V8.2(3) and we want to upgrade our internet bandwidth. Our ISP says OK but we need to install different physical circuit, upgrade CPE router, etc.
Then they say, btw your globally allocated IPs will change - this is a problem as we have Site-to-Site VPN Tunnels, IPSEC RA, etc.
ISP are proposing to give us a 3 month period whereby old & new IP blocks will be routed to our ASA (by means of secondary IP address on their Cisco CPE).
Multiple IPs on the same physical i/f on the ASA require sub-interfaces/IP Addresses/VLAN ids on my "outside" i/f.
Is this going to horiibly break Site-to-Site VPN Tunnesl, IPSEC remote access ?
Will VLANs work at all with IPSEC on the "oustide" i/f at all ?

Cisco WAN :: ASA 5520 EIGRP Route Filtering?

Feb 26, 2012

I have an ASA 5520 connected to a Cisco 6509E, and we're turning up EIGRP between the two. The problem that I'm running into is that there a few static routes (including a on the core that's being redistributed into the EIGRP AS, and I need to block this from being propagated to the ASA. The ASA only has the capability to use an ACL in conjunction with a distribute-list, and I can't find a way to filter the default route ( /0), while allowing everything else.

Cisco VPN :: 5520 VPN Filtering And Access From Local To Remote Site

Mar 21, 2012

I have configured vpn filtering on all my l2l vpns. I have restricted access from remote to local resources only to specified ports. It works perfectly.But I want to have also full access from local to remote networks (but still preserve restricted access from remote to local). As I now VPN Filter works bi-directional with a single ACL. So is there some way to open all traffic from local to remote and still restrict remote to local traffic? ASA 5520 8.4(3)

Using MAC Address Filtering?

Dec 19, 2011

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

Cisco Wireless :: MAC Address Filtering In Aironet1130AG

Dec 29, 2011

I'm attempting to block about 10 to 15 users on the wireless by using  MAC address filtering on the Aironet.  I referenced the following link: URL,The  policy does indeed work, but once I apply the filter all traffic on the  wireless for that particular VLAN stops.  Why would this happen?  I  wouldn't think I need to configure anything else for this to work, but  maybe I'm wrong.I was looking over the config and I noticed that each time I added a MAC address to the filter, it would create and access-list 701 deny 0000.0000.0000  ffff.ffff.ffff   Once I removed this access-list, traffic starting flowing again, but  when I add another MAC address the access-list shows up again.

D-Link DIR-655 :: Network Filtering / 24 MAC Address Limit?

Jan 23, 2013

I have had a great experience with my old DIR-655 (rev A) router.  However, I would like to upgrade to a newer and better D-link router for my home that contains many well-connected children. Which routers are like my DIR-655, and have better overall performance than the DIR-655 without necessarily using the benefit of the 5 GHz second band.   What better performing routers can record more than 24 MAC addresses in the Network Filtering area?  I understand many people don't agree with MAC address filtering, but I like it to keep my kids from giving out my network password to all the neighbor kids and their friends too.  So, MAC address filtering works for me.  Or, should I just get an updated version of the DIR-655?

Cisco Routers :: RV180 / RV180W - MAC Address Filtering And IP Biding

May 24, 2012

I'm interested by the router Cisco RV180 or RV180W.
So as to increase security, i would like to set a MAC adress access restriction for all peripherals that would be connected to the router (10 computers, 2 servers, 6 Synology NAS) : only allowed MAC adress should access to the internet and network ressources.
Does the Cisco RV180 or RV180W have an IP to Mac biding feature and a Mac adress restriction feature ? If yes, how many peripherals/computers can be set ?
For example, only 30 mac/IP adress can be allowed on my actual router and it is not enough.

D-Link DIR-655 :: Web Filtering Doesn't Work When Linked To MAC Address

Jan 5, 2011

My DIR-655:
Hardware Version: A4
Product Page: DIR-655

The problem is that Website Filer doesn't work if on STEP 3: SELECT MACHINE of Access Control the machine was selected by MAC address. When the machine was selected by IP everything is fine.The problem is that IP addresses are assigned dynamically, so how to make sure that the policy would be applied to the same machine?

Belkin Routers :: N150 - When Check MAC Address Filtering It Seems To Be Disabled

Dec 25, 2012

I have a Belkin N150 wireless router. I have enabled MAC Address Filtering as an added level of security. However; whenever I access the router, and if I check that page; the check mark for the option to enable the filter is always blank.

I have checked the option, clicked Apply Changes, and logged out of the router. i went back in this morning, to check the security logs. (Looking like someone is trying to jump on my network) I didn't see anything there, but when I checked MAC Address Filtering; there was no check mark indicating that the filter was turned on.

Linksys Wireless Router :: E1000 / MAC Address Wired Filtering?

Jan 19, 2011

I just want to allow specified computers wired access to the internet via the E1000 router.  Here is the problem I am currently working on: 

(1)   Setup the E1000 unit to allow only one PC 'C1' (MAC: 91:E6:BA:25:91:58) wired access to the internet.

(2)   Add another PC (unknown MAC address) to the LAN side of the E1000 unit and see if it is being blocked by the 'Access Restriction' policy that was setup.  

(3)   Can’t get the above done – the second PC is able to surf the internet although the policy is enabled. 

Notes:(a) Ref: 'Access Restrictions' web page or see Page 26 in the User Guide .(b) The unit has the latest firmware already installed: Firmware Version: 2.1.01 build 5Dec 3, 2010.(c) The internet port of the unit goes to the ADSL modem in my house.(d) Unplugged the unit for 10 seconds as advised by one of your technicians, still no difference.(e) I can deny PCs, but the allowing only specified ones seems not to be doing anything.By the way, can the E3000 or E4200 do the above?

Linksys Wireless Router :: E1200 Can't Setup MAC Address Filtering

Sep 12, 2011

The browser-based settings utility for my E1200 can't setup MAC address filtering. I go to the "Wireless MAC Filter" page and enable MAC filtering.When I click the “wireless client list” button, a new window opens saying “IE cannot display the webpage”. This always happens when I have a wireless connection active.When there are no active connections, then IE properly displays the MAC address table, but it is empty since there aren't any computers connected to the router.

Cisco Firewall :: 5520 - Object-group With Network-object Containing IP Address Range

Apr 7, 2013

Does the ASA treat an object-group with a network-object containing a range of IP addresses as a netmask? For example, I can apply this configuration without the ASA throwing any errors though the configuration calls for a 'net mask':
object-group network test
network-object-group mode commands/options:
A.B.C.D  Enter an IPv4 network mask
sh run ob id test
object-group network test
I found that in the documentation it requires a netmask as oppose to a range. Is this a bug in the code? I am running code version 8.0(5)23 on a 5520. If this is not a bug how does the ASA treat this type of configuration when applied to an access list? When I ran a quick packet trace and denied access from that range it looks like the ASA doesn't read that configuration properly.
