Cisco Firewall :: 2851 HTTPS URL Blocking Using Class Map

Aug 3, 2011

I have a request for blocking urls using a class map. I have made this work with HTTP, however it does not work for https. This is a 2851 router with IOS Version 12.4(15)T7. I see i could use the command "match protocol secure-https" however this does not let me specify any specific urls.
 
Does a new IOS version will support what I'm trying to do? Or if there is another way?

Cisco Firewall :: How To Filter L2L Traffic To A PIX 7.2(4) (or ASA)

Feb 6, 2013

I've got a PIX running 7.2(4) with its outside interface on the Internet.  The only thing this PIX is doing is acting as the endpoint for an IPSEC LAN-to-LAN tunnel with an Internet-connected ASA on another network.
 
I'd like to filter inbound Internet traffic to this PIX so that only the designated ASA can attempt to establish an IPSEC connection -- in other words, I want to prevent any other device on the Internet from even being able to attempt to establish an IPSEC connection to the PIX.  As far as I know (and have seen), this can't be done with an access-list on the outside interface, since that access-list doesn't apply to traffic to the PIX itself.

Cisco Firewall :: ASA 5505 - HTTPS Traffic Through DMZ Interface To Internal Exchange Server?

I have an ASA 5505 with the base license,When I setup the DMZ interface I had to add the deny access to the inside VLAN.  The DMZ works fine with WiFi on it, but user's iPhones can't get email unless they turn WiFi off.Is there a simple way to allow HTTPS traffic through the DMZ interface to our internal Exchange server which is NAT'd on the 5505's external IP?

Cisco Firewall :: ASA 5505 - Redirecting Http And Https Traffic To Proxy Server

Aug 5, 2008

I have an ASA 5505 that I am using to connect my contractors to via an inside interface, the outside interface is my private LAN. I have setup on our corporate Proxy server to allow traffic from my outside interface of my  ASA to go to the internet without credentials BUT log internet activity. The question is I want to know if the ASA can send that http & https traffic to my proxy server and all other traffic to my default route? I want to be able to send all internet traffic to my proxy server. This will avoid me asking the contractors to place proxy credentials in their browsers.

Cisco WAN :: HTTPS Traffic Slow Over 877 Router

Feb 12, 2013

I have reconfigured the router from scratch using all sorts of methods and can not work out whats wrong, basically when the client is going to their bank the login screen takes upto a minute to load, and the same with hotmail. However using a cheap billion router these login screens are instant
 
Checking the CPU usage shows the CPU is hovering around 5-20% at the worst of timesThere is about 10 machines behind this router and they do not do that much intensive work over the link besides Outlook Anywhere (HTTPS)I have put a ACL on the LAN connection to only allow 1 machine in and still no luckI have also updated the IOS to c870-advipservicesk9-mz.124-24.T4.binAll other traffic runs fine over the link and there are no complaints on standard HTTP traffic

Cisco Firewall :: ASA5585 WCCP-GRE Redirection To Websense Times Out?

Dec 9, 2012

I have a ASA5585 running 8.4 that is redirecting Internet http to a websense server via GRE.The integration is working fine, except when a user PC sends a large packet (~1500 bytes).With WCCP/GRE headers, the user packet is too large to be transmitted to websense, so the ASA fragments the packet in two and transmits both to websense.
 
A sniffer trace confirms that both fragments reach the websense server, but the TCP packet is never acknowledged.User-side TCP retransmits the large packet three times over 15 seconds, and eventually retransmits fine with smaller packets.  The 15 second delay is of course not acceptable.Users and Websense server are both on the Inside interface.
 
We are considering imposing browser proxy to websense (which works fine), but would prefer not, considering the increasing diversity of devices.

Cisco Firewall :: IOS Router 2851 Logging

One of our client has a  Cisco IOS router 2851 with Zone Based Firewalls, enabled.
 
We tried to configure the router to receive the logs and we receive it in the following format:

What are the exact steps required to recieve the above format? If the logging needs to be enabled on Access Lists, need exact commands, from the console config mode?

Cisco WAN :: 2851 - VPN Traffic Not Captured By IPSec Access List

Aug 29, 2012

we have two 2851's.  One in Australia, one in NZ, IPsec VPN between the two.
 
We have multiple subnets behind the tunnels. From all the sunbets in Aus we can reach all the subnets in NZ, except for one.  From NZ we can reach all the subnets in Aus.  The traceroute and pings from the subnet in question in Aus goes out the internet interface of the router instead of going into the tunnel.
 
The subnets in question are 10.110.220/24 (Aus), 10.110.250/24 (NZ)
 
The access lists at both ends cover the traffic required but for some reason when leaving Australia the traffic is not captured by:
 
Crypto Map "AUS-SYD" 20 ipsec-isakmp
Description: Auckland VPN
Peer = 203.167.249.46

Linksys Wireless Router :: Unable To Access E3000 Via Https

Feb 29, 2012

I can not access my Linksys E3000 router via https://192.168.1.1.Before this mishap, I was able to gain access to my Linksys E3000 router via http://192.168.1.1 and/or the Cisco Connect software application on Windows 7. Yesterday, I went into my router's administration page and disabled http, and enabled https. I then closed out all browsers, restarted them and entered https://192.168.1.1
 
After that, I learned quickly I made a huge mistake to make these changes. I simply can not access my router admin wired or wirelessly. Accessing the internet works great, but router admin page is a no go.Firefox and IE states, "There is a problem with this website's security certificate." and was unable to proceed.Firefox even gave me the option to accept a security exemption to proceed, but that failed.
 
I have also tried using the Cisco Connect utility, and that also failed. I have taken these steps and not been able to access my router's admin page.I don't want to take the last final resort to reset my router and re-enter my settings again. I know I saved the router's backup file somewhere, but can't find it.Is there another way for me to gain access via https with http disabled? All I want to do now is go back in and change it back to enable http access.

Cisco VPN :: 3030 - How To Filter Web Traffic

May 29, 2013

Most of our VPN connections are done with our Cisco 3030 and the internet goes out the ASA. We are able to filter all web traffic by doing a a span port for web traffic.
 
When we move VPN connections to the ASA we will loose the ability to span web traffic becuase its coming in and going out the same interface on the ASA. We will loose the ability to filter web traffic when this happens.
 
How we can filter web traffic on VPN connections on the ASA. We are using websense. I know there is some integration that can be done with the ASA and websense but it doesn't have all the capabilities as doing a span port for websense to monitor.

Is it possible to configure cisco router like C3800 or catalyst switches like C4500 or C2960  to filter traffic based on allowable mac addresses only? I would like only to allow those devices that belongs to the domain, meaning if a user connects a computer or any devices that concerns network which I have not allowed the mac addresses, it will be denied access to the network. However, any of the allowable devices could able to use any port of the switch, meaning I dont want to associate an allowable Mac Address to a physical port on the switch.

Cisco Switching/Routing :: 6500 / How To Filter IPX Traffic

Feb 23, 2013

We have a lot of IPX traffic flowing through a switched network and we are being asked to filter it from a network standpoint. At one point they were using IPX in their network, but no longer need to, so they still have a lot of machines spewing out IPX traffic. We have removed the IPX routing commands from our distribution switches, (Cisco 6500), but after running a short 10 minute Wireshark capture I'm still getting a good bit of IPX traffic from a lot of different devices.

Cisco Switches :: FS-300-24 QoS To Limit HTTP And HTTPS Traffic

Apr 20, 2011

Never seen a Cisco, or any other L3 switch before. Nor an Lx router. Any step by step,or class room or web based training, or a partner or Cisco helper to get us up to speed on this.Goal is to limit http and https traffic in favor of telnet to an AIX server and RDP to a Windows TS. Printing would be ahead of http/s and below the others.
 
Interstingly, the web site promises 9 videos, but there are only 8.  The demo guide says about OoS:  "Coming Soon".Where to go? Who(m) to call?
