I have ISA server 2006 sp1 and i can install many good software to management of network like gfi web Mon, soft perfect bandwidth manager and many more.
And I have an ASA 5520 AIP-SSM module so what security management Asa can give and what security feature it has and also so I will convert my network firewall from MS ISA to CISCO ASA.
We are moving from a different vendor to ASA 5520s. So far my "training" for Cisco consists of s Cisco press book, some white papers and guides, this website, and a bunch of mistakes. So, I have what is probably a pretty basic question for most folks.
What is the difference between Firewall Access Rules and ACL/ACE? And when to use which?
for example: on my ASA 5520s I've set up an Interface for my internal LAN: 172.16.x.x., a DMZ 192.168.2.0/24, and an interface for the Internet side. The 5520 is set up as a routing firewall betwen my internal lan, DMZ, and Internet.
If I want to allow my internal users Internet access for http and https would I use a Firewall Access rule?For most of my rules allowing outbound access from my 172 LAN and DMZ and inbound access to devices in my DMZ can I mostly utilize the Firewall Access Rules?
What's the difference between VPN Plus license and Security Plus license. I have new 5520 shipped with VPN Plus license.Also does it require a seperate license for Anyconnect for Mobile and AnyConnect Essentials.
View 1 Replies View RelatedI recently inherited a Cisco 2911, that appears to have had Firewall rules imported into Externally Defined Rules. ACL's are currently allowing/disallowing traffic. However, there are no firewall rules configured. To meet compliance we need to have Packet Lavel Inspection (Firewalled) rules. There are two areas in the router, under ACL area, and under Security. What is the difference between these two Firewall areas?Are both areas providing packet level inspection?Can I build Firewall rules (within the Security area) to replace the ACL's?
View 2 Replies View RelatedI am building 20 pairs of failover firewalls for work and I was wondering from the users of the new code 8.3 - 8.4 if there are anything to watch out for. I know NAT changes from 8.2x to the newer 8.3 - 8.4 lines but would like to hear about real world thoughts on it.
I am working on my CCIE-Security on the side and right now the lab uses 8.2 but I am a good 6 to 9 months out, so I wonder if there will be a change in the lab to 8.3 before I try to go take it, what code to load and use on the production boxes.
Can any1 tell me wat is the difference between ASA-SM1 and FWSM.

View 3 Replies View Relateddo you think there would be a visible (or negligible) difference in internet speed if I used a hardware firewall as opposed to the router's inbuilt firewall?So assuming that all switches/ports were Gigabit Ethernet compatible (including the firewall itself), would it be a better idea to turn off the router/modem's firewall and use the hardware firewall, or would it be best to just stick with the router firewall?The reasoning behind this is that I'm not a big fan of Netgear... or their firewall system. After recent DDoS attacks (and IP address changes), I've decided to put a computer that was lying around to good use - Use it as a (Linux) firewall. iptables, here we come. - Yes, the Netgear router (CVG824G) has died a few times. Probably going to get upgraded to a NG CG3000, which uses (more or less) the same firewall system, I assume.
View 6 Replies View RelatedI'd like to see some REAL LIFE comparisons of ASA firewall throughput (a bit like this one for ISR G2 Routers - [URL].
The reason I ask is that I recently upgraded a firewall from an ASA5505 to an ASA5520 on a small network where the only outside connectivity was a single 10meg Internet circuit with an IPSEC VPN (not landed on the firewall but on a router) to another site.
When I swapped out the firewall the users noticed a big improvement. The firewall is not doing anything out of the ordinary - no IPS or VPN, just standard state full inspection.
I have an asa 5520. How would I configure my dedicated management interface to be able to route off subnet while the firewall is in transparent mode?
View 1 Replies View RelatedWe are using the newest release of AD Agent (1.0.0.32.1, built 598). The ASA Firewalls 5520 are having the software release 8.4(3)8 installed.When somebody tries to connect thru the Identity based firewalls from a citrix published desktop environment (PDI) the connection is not possible. Checking the ip-of-user mapping on the firewalls (show user-identity ip-of-user USERNAME) mostly doesn't show the mapping of the USERNAME and the PDI the user is logged in. The user-of-ip mapping of the PDIs IP-address shows mostly other users, which then are used to authenticate the acces thru the firewalls.
What is interesting, that on the AD Agent using "adacfg.exe cache list | find /i "USERNAME"" i can't see the PDIs IP-address neither because it is mapped to another user.Is Citrix Published Desktop environment supported to connect thru Identity based Firewalls? How AD Agent, Domain Controllers and Firewalls are working together? On the firewalls with "show user-identity ad-agent we see, the following:
-Authentication Port: udp/1645
-Accounting Port: udp/1646
-ASA Listening Port: udp/3799
Why Cisco does use 1645 and 1646 and not 1812 and 1813?The Listening Port is used for what purpose? we tried the AD Agent modes full- download and on-demand with the same effect.
I try to launch a LAND Attack against my firewall ASA 5520. Everything will work fine. But why, I think it should not work. I use a little tool where I can user a spoofed address, with a cluster shell and attack the firewall interface with the source of 127.0.0.1 ore the ip address of the interface as the source and destination. Then I get a cpu load of 89% with only two host. With IP tables I can use kernel processes to prevent this. But I don´t find anything for ASA.

I have a serious problem with my corporate firewall, witch is an ASA 5520, fv 8.3, with 8 +1 interfaces. It suddenly started to crash every 10/20 minutes and rebooting alone.
First of all I checked system resources witch are in a very low usage state. I also checked interfaces errors, but nothing strange come out o from error counters analysis. I tried disabling logging and all the service policy rules configured, but nothing changed.
Nothing changed and firewall continue restarting by itself.
Last logs I received before crash were:

View 2 Replies View RelatedI have an ASA 5520 in my company which does all our NAT and Firewall access control. Currently there is a rule in place to allow an incoming connection on port 2222 from a specific ip address to allow access to a web app our developers created. This is a test before the web app is released live. Now the web app can communicate with the specific address and port but the incoming connection on port 2222 isn't getting through. Everything looks great in the firewall but how can I log any hits this ACL takes to identify any potential problems?

For example ASA1 outside interface connects to an upstream switch and you setup sla monitor with icmp echo to ping that switch. The switch goes down and you need the other ASA2 to become the Active ASA. Can the sla monitor be automatically integrated with the failover commands for this to happen?
