Cisco Firewall :: 2821 Router - Can't Configure URL Filtering Using Classic Way
Aug 16, 2012
I have Zone Based Firewall running on a 2821 router and would like to configure Url Filtering with Websence . IOS running on that device is c2800nm-adverterprisek9-mz.150-1.M7.bin . Once you have ZBF config you cant configure url-filtering using classic way ( ip inspect ) and this has to be done using class , policy maps .For this to to happen it is required to have match protocol http command under the class map , it wont work using the match access-group command.[code]
Once I put match protocol http command browsing becomes dead slow , also without using match protocol command I cant continue to configure Url Filtering . Is this a problem related to IOS where match protocol command isnt working fine . I have checked CPU utlization of Router and it was roughly near 7 percent .

Im notice after configure the trend micro url filtering on a Cisco 2821 high latency on Http navigation, the latency on the ping for the requests shows a 245ms latency, but if i disable this feature on the router, returns to normal navigation and decrease the latency up to 70ms.

I would like to know how to configure my DIR-600s firewall UDP Endpoint Filtering. I ve read some guides and I ve got to configure this to Endpoint Independent in order to play League of Legends. The problem is that I can see the option Firewall & DMZ but then I don't see the UDP or TCP Endpoint Filtering options.

If you are familiar with the Huawei HG520s router, I want to filter an ip range (ex. 192.168.1.10 to 192.168.1.255) so that no other users can connect on this ip range and start using the router.

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 .

I've 3 interfaces on router:
Gb0/0-ISP01 with DHCP client
Gb0/1-ISP02 Static IP 192.168.2.x/24
Fa0/0 - LAN 192.168.1.1/24
I want to know, how to configure:1. Set the IP of interface Gb0/0 as dhcp client from ISP01 and make it as default route.
2. How to configure the ip nat.....overload?
3. How to use the ip sla to monitor internet connectivity to 8.8.8.8 for ISP01, if it fails, to go to ISP02.

I want to configure my router to use 2 ADSL lines each with a dialer and a modem in RFC2684 mode. I have a 2821 (IOS 12.4) with an HWIC-4ESW.
My network topology is like this :
ADSL Modem 1 (RFC2684) --
(Fa0/0/0)
Router -- (Gi0/1) MyLAN
(Fa0/0/1)
ADSL Modem 2 (RFC2684) --/
1. I configure my DSL Modem in RFC 2684. The first use 172.16.0.2/29 and the second 172.16.0.3/29. I connect this devices to Fa0/0/0 and Fa0/0/1.
2. I configure Vlan1 to use the network configured on my modem :
interface Vlan1
ip address 172.16.0.1 255.255.255.248
3. I try to ping my devices :
#ping 172.16.0.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.16.0.3, timeout is 2 seconds:

I have a Cisco SR-520 router which I am trying to configure and install the IOS content filter. I have read many of the documents on this but some of the lines do not work, from using the pages belowURL
you are supposed to enter parameter maps as follows:-
parameter-map type trend-global global-param-map
server trps.trendmicro.com
cache-size maximum-memory 256
cache-entry-lifetime 1
The router has 12.4 (20) T4, which is supposed to be supported, the only other way of configuring is using CCP which is not compatible with SR-520's you recieve hardware not supported message's.

I have a 2821 Router with several IPSec Tunnels on it. I would like to replace this with a ASA 5510. My hope is to swap these out with minimal impact on the active Tunnels. I have the details of each Tunnel well documented. My question or concern is in configuring the Tunnels on the ASA. Do I need to configure IKE proposals in just IKEv1? If I use IKEv2, my concern is that there will be compatibility issues with the remote end of the Tunnels, or is IKEv2 functional with IKEv1? If not, then, do I just configure everything in IKEv1 and ignore IKEv2?

I did a simple speed test comparing my EA3500 and Linksys WRT54GL. I used DSL Reports for the test. I was quite shocked and am wondering if the difference is due to the poor wireless driver in the Classic firmware that was updated in the Cloud firmware. Here are my numbers: EA3500, Classic firmware Download average 475 kb/s Upload average 725 kb/sLinksys WRT54GL Ver 1.1 (latest firmware) Download average 3250 kb/s Upload 725 kb/s
Needless to say I have gone back to my trusty WRT54GL until Cisco decides if it will update the Classic firmware and give us 2nd class Cisco customers the same hardware the 1st class Cloud customers have. Time will tell.

What is the best way to monitor an Internet Edge router from the Internal network behind the Firewall?We want to pull more information from the edge router like netflow. We can use SNMPv3 and ACLs to keep the router secure.
But I am looking for the best config to keep both the router and firewall as secure as possible while still allowing us to monitor performance and faults.I am running an ASA and a 2821.

Is classic firmware 2.0.37 for the EA4500/E4200v2 vulnerable? I see that the workaround is to use the latest Smart Wifi firmware. How soon can we expect to see a classic firmware update? [URL] Linksys quote taken from a random review that I found on Amazon below......The manufacturer commented on this review(What's this?) Posted on Jul 26, 2012 9:53:51 AM PDT Linksys says: (MANUFACTURER) Jason, Cisco Linksys plans to offer Software Updates to the EA Series router for customers who choose a local management option (including Cisco Connect/Classic). We will continue to provide Customer Care and deliver SW Updates to address Security, Critical Bugs and User Interface issues as required. Customers can comfortably stay with the local management option and Cisco will deliver continued support.

I may be replacing my e1550 soon and am looking at both the N750 and N900 class devices. While the EA3500/4500 seem to be a really good deal with a lot of bang for buck, I do have one concern...
As I have zero intention of ever using Cisco Cloud Connect, I would need to stick with the Classic firmware. While Cisco did quickly push out a solution to get the routers back to Classic after the initial Cloud Connect deployment fiasco, I cannot seem to find any commitment from Cisco to continue to support the classic interface (other than "“Cisco will continue to support both local and cloud management options for our customers.”). Even more disconcerting is that the current evidence seems to indicate that they are not. [code]
So, while I do understand that many of the updates have been Cloud Connect specific, some of these changes are in fact global/driver updates. As an example, according to the release notes, on June 25, 2012 the EA3500 CCC firmware v.1.1.38 (Build 138143) updated the WiFi driver, apparently the Classic never received this update.

I just ordered an EA4500. It should be here in a few days. After reading most of the 45 page Cloud Experience thread, I am leaning toward using the Classic Firmware. I have read the release notes but want your input:
1. Is the Classic Firmware stable or buggy?
2. Are there any features (besides cloud) that won't work? dual band? usb storage? dlna?
3. Where is user manual for Classic users?

One of our customers has an ASA5510 with CSC SSM-10 security module. The software version of the module is 6.6.1125.0.Is it possible to do https filtering with this module ? The customer is complaining that this is not possible...from Cisco I've read the following:
• HTTPS Filtering
– Able to allow or block HTTPS traffic.
– Supports group-based and user-based HTTPS policies.
– Includes URL blocking/URL exception list support for HTTPS domains.

I am running a Cisco ASA 5510 with Trend Micro Interscan. We have it set up to filter https except for a handful of sites. It is filtering the ones we don't want ie: facebook, and youtube. Though it is causing all other https to slow to a crawl. Therefore some sites it times out on us. What should we be looking for to change so it isn't slowing the allowed sites down?
Version numbers
ASA - 8.4(3)
ASDM - 6.4(3)
Trend - 6.6.1125

Alright, well I have a Cisco 891w router and have just about everything up and ready to deploy. I'm primarily using Cisco CP 2.4 to provision the router with minor tweaks being done in the CLI. I want to set up a filter to allow access to roughly 20 websites for the majority of my network which is all on the same VLAN. The ip ranges are x.x.x.10 - x.x.x.169 which I have set into a Network Object group called limitac. The second group ranges at x.x.x.170 - x.x.x.199 and is called allowac. I have set up DHCP bindings for all the devices that will connect to the network but I want to set up a web filter for only the first group. I cannot seem to find anything in the Cisco CP manual or the IOS manual for setting up filtering for a range of IPs only. Primarily there are a few computers that need full access to the web while the others should only have access to the sites I set up in the filter.

I have big trouble with easyvpn clients access filtering on asaos 8.4.1. I have couple of remote offices with hardware clients (cisco 87x, 88x) configured as easyvpn clients to Asa. Default route in it's routing table pointing to the Virtaul-Access interface (easyvpn connection to ASA), so there is no split tunneling or any kind of nat on the clients. I have ip-telephony deployed across remote offices. This remote offices should be able to call to each other.
On the ASA i have configuration for this purpose:
same-security-traffic permit inter-interface
same-security-traffic permit intra-interface
But as soon as I configured it, remote users obtain an ability to access Internet without any restrictions although there is couple of access-lists configured on the outside interface pointing to easyvpn clients. Then there is no same-security-traffic commands i can filter out access to internal and external resources correctly, but remote offices can't communicate with each other
