Cisco Firewall :: ASA5510 Adding New Public IP Block

Nov 1, 2012

My web server is out of public IPs.  I requested more from my ISP and I got a different range with a different gateway.  How do I handle the configuration on my Cisco ASA? Without any configuration changes to the firewall I saw the traffic hitting it and being blocked.  I added an access rule to allow the traffic.  I added a virtual interface on the ASA.  I added a virtual interface on the web server.  Using "Packet Tracer" the traffic flows from the outside interface to the new virtual interface.  But I'm unable to access my web server and I don't see any traffic on that IP reaching the web server.Using Cisco ASA 5510.

Cisco Firewall :: SA520W - Blocking URLs

Mar 17, 2011

I purchased a SA520W for my company, and i have some probles for configuring firewall. I want to deny access to facebook, youtube and twitter but not for 4 hosts which needs this websites for work. I tried to configure content filtering > blocking URLs but with this solution, I deny acces for all users, So, I tried to make IP v4 rules :

The 4 hosts who may access to these websites are to 127
Example :
Service : Any
Action: block always
Source hosts : to
destination hosts : (one of the facebook's ip)
but it does not work. So, I am looking for an other solution, or maybe my rule is not correctly configured ?

Cisco Firewall :: ASA 5510 Filters URLs In HTTPS?

Nov 22, 2011

My company uses a pair of 5510 ASAs as the gateway to Internet. I once configured policy-map to filter certain webpages (facebook, twitter, ...etc) and they work fine. However nowdays those websites all support HTTPS. In the https the URL seems encrypted so can't do regex match... Is there anyway that I can still block those webpages?
Another two ways I can think of are

1. Block IPs (don't really want do this unless absolutely necessary)

2. Block DNS for the URL (however they can work around by setting static DNS entries)

Cisco :: Unable To Access ASA5510 - Cannot Ping Interface

Oct 22, 2012

I have been working on figuring out a VPN problem on my companies ASA5510. I was accessing the device via: ASDM, SSH using Putty, and even initially with a console cable (also using Putty) using a computer in the networking closet. All 3 of these access methods worked properly for me.I believe I may have inadvertently changed something as of Friday using ASDM. I am mostly assuming this because, as of yesterday I can no longer connect to the device. I actually cannot even communicate with it (ping the interface I normally use to manage, which I could previously ping). No computer on the same subnet as me is able to ping the interface. The device is still accepting VPN connections, dishing out DHCP addresses and everything else it normally does, but I really need to be able to gain access to it again. I am thinking to reboot the device when there is some downtime, in the hopes that ASDM doesn't save to startup-config and only to running-config.

Cisco Firewall :: ASA5510 Secondary Firewall Crashes After Upgrade To 8.4.1

Jun 29, 2011

I have two ASA5510's set up in failover, and the secondary keeps crashing after doing the interface checks when bringing failover up. This only happens if I try to upgrade the image on the secondary to anything newer than 8.4.1 (I've tried with 8.4.1-11 and 8.4.2). The primary one run just fine with new images.
I don't have the exact error right now, as I need to do a screen capture from console. It's just a huge crash dump.Are there anything I might have missed during the upgrade? Should I cold-boot both the firewalls in the correct order?

Cisco Firewall :: ASA5510 Firewall Interface Speed

Jul 21, 2011

I have a ASA5510 and I have a question about the speed the ports can handle, here is one port:
-interface Ethernet0/2
- speed 100
- no nameif
-no security-level
-no ip address
it's ethernet and not fastethernet so I figure it will only go to 10Mbps, but at the same time I can hard code the speed to 100.

Cisco :: Preventing Unwanted Access Points 1242s

Feb 26, 2013

This is just a tip that we used on our controllers that I wanted to pass along. We were having issues with unwanted access points associating to our controllers. We had a stack of older 1242s that came up missing and hit our network. On way we came up with to prevent this was to number all of our wlans above I'd # 16 on the controller. By default the default ap group allows all wlans from 1 to 16. By starting with 17 we are not allowing any SSIDs in the default group. All if our production access points are in their own ap groups. Any access point that hits our controllers that has not been configured with the correct ap group name will be in the default ap group and will not be servicing any SSIDs.I know there are other ways to set this up but this was a tricky way for us to set it up and see who calls about there wireless not working.

i want to block all internet access on all my computers from the time range of 9 PM to 8 PM. Yes, that gives 1 hour of internet access per day. However, it seems that there are certain rules of the router that won't let me do this. It seems I can't make 2 different policies for PC's within the same IP range ( to , it gives me the error: "The values you entered are invalid. Please try again."every time I try to do so. And when I try to give the time range from 9 PM to 8 PM it gives an error stating that the end time must be bigger than start time. I am using the WRT54GL with firmware v4.30.7.
