DLink Dir-632 IP Filtering Feature

Sep 19, 2011

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.

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 VPN :: Does ASA5505 EzVPN Support Reactive Primary Vpn Server Feature

Nov 24, 2011

i am going to configure asa5505 as the azvpn client . and configre primay and secondary vpn server in the list.i find some feature that is support by ios ROUTER  ezvpn, not sure it will be support on ASA ezVPN???
will the ezvpn   fall back to the primary vpn server , if primary back on line,  on ASA? The Reactivate Primary Peer feature allows a default primary peer to be defined. The default primary peer (a server) is one that is considered better than other peers for reasons such as lower cost, shorter distance, or more bandwidth. With this feature configured, if Easy VPN fails over during Phase 1 SA negotiations from the primary peer to the next peer in its backup list, and if the primary peer is again available, the connections with the backup peer are torn down and the connection is again made with the primary peer.

Cisco Firewall :: NAT-Control Feature In ASA 8.4 (2)?

Aug 26, 2011

I'm a bit confused about new NAT functionality in Ver 8.4(2). I've gone through all the documentation as well as different blogs but still not clear about the various things.One of these is NAT-CONTROL. I understand that this has now been removed. Does this means that traffic traversing the ASA doesn't need any NAT'ing commands unless specifically required by the administrator? In other words by default traffic is allowed through the firewall without any NAT'ing.
My Second Query
I've ASA5520 running ver 8.4(2). For inside interface, I've created 13 x sub-interfaces under Gi0/1. All have same security level i.e. 100. What I want to achieve is that:Traffic from these sub-interfaces should be NATTed to outside interface when going to internetBut, intra sub-interface traffic should be allowed without NAT'ing. I'm using RFC1918 on both sides i.e. source / destination The first point is not a problem it's working, however. I'm struggling with the second point. On ver 8.2, it wasn't a problem, I used NAT 0 with access-list permitting RFC1918 addresses as source and destination.

Cisco Firewall :: Name Feature On ASA5550 8.4

I have upgraded ASA5550 version from 7.2(4) to 8.4(2).
On version 7, I am used to "names" command, like this:

By addition, when configuring acls it was very usefull, for example: 

access-list inside_access_out line 15 extended permit udp host Picard host eq snmp 

On version 8, I have verified that names replacement is no more available: 

ASA(config)# access-list outside_access_in permit ip host ?

configure mode commands/options:

A.B.C.D  Source host IP address

Cisco Firewall :: Active IPS Feature In ASA5500-X?

May 5, 2013

Should we active IPS feature in ASA 5500-x by useing license?in the 5500-x ordering guide:IPS is only sold as ASA-IPS combo SKUs i.e., one cannot add IPS service as an option on top of ASA SKU. For example, if IPS service is desired on ASA 5515-X appliance, the relevant SKU is ASA5515-IPS-K8 or ASA5515-IPS-K9.But my customer has actived it by using the ASA5525-IPS-SSP on ASA5525-K9.

Cisco Firewall :: ASA 5510 HTTPS Filtering Bog Down

Feb 15, 2012

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

ASDM - 6.4(3)

Cisco Firewall :: 891w - Web Filtering For IP Ranges?

Feb 24, 2011

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.

Cisco Firewall :: IOS Content Filtering On SR-520 Router

May 17, 2010

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
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.

Cisco Firewall :: ASA 8.4.1 EasyVpn Clients Filtering

May 3, 2011

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

Cisco Firewall :: 3.2 (18) - URL Filtering In FWSM Without External Server
