Is it possible to automatically shutdown the OUTSIDE interface on a Cisco ASA 5520 in case of intrusion?.
In my opinion if there is an attempt of intrusion, just the device would stop it. If it cannot detect it, how can the device recognize the event and so shutdown the interface?. Am I correct?
Our firewall expert has gone off on long term illness leave and I am trying to pick up the pieces :-(
We have an ASA 5520 (local office) talking to another ASA (remote office) via a VPN Tunnel.
My 1st problem is that I cannot ping from my inside network (local) to the outside interface of my remote ASA.
My 2nd is that I have debug enabled on my rules but am not logging anything.
The client is only interested to have one-WAN(MPLS) and One internet circuit with Dual ASA5510 primary/failover configuration. In the event primary firewall fails, there is no direct WAN/internet connection to failover firewall. I beleived that to mitigate the issue, I needed to add a layer 3 switch , and have each circuit (MPLS/Internet) or (modems/routers) connect to a L3 switch. L3 switch will do the vlan based routing based on the state of firewall. ? am i correct? The client want automatic failover to secondary firewall in the event the actual firewall failed without impacting the day to day business.

I just want to know is it possible to do a direct upgrade from 8.2.3 to 8.4.x ?Secondly, will ASA automatically convert all the configuration from 8.2 to 8.4 format during the reboot after the upgrade?
in the ASA Migration Guide for Version 8.3 says about real ip address: "All of the access-listcommands used for these features are automatically migrated unless otherwise noted"
But my ACL's have not been migrated to real ip address. In my migration log:

I would like to schedule automatic backups of our ASA5500's OoO-hours:
1. SSH from secure server and create _FULL_ backup - what would be the CLI command(s) ?
2. SCP from secure server and retreive file(s) - what is the location of the file(s) ?
It is my understanding that the FWSM for the 6500 series switches uses a 6 port Etherchannel on the backplane to communicate with the 6500 series switch.Can you shutdown vlan1 on the switch and still communicate with the FWSM? I was under the impression that you could not (although I am looking at a config with it shutdown)
View 1 Replies View RelatedWe have pair of ASA5585 (ver 8.4(4) with IPS module configured with Active/Standby failover. There are total 09 interfaces are connecting to different zones in the firewall and out of which three(3) interfaces are connecting to Palo Alto 2nd layer firewall. When we test the failover whatever interfaces not connecting Palo Alto failed or shutdown, ASA triggers the failover to other unit, however the Palo Alto is not detecting this failover and it still keeps its previous Active Palo Alto to pass traffic, thereby failing passing traffic on Active firewall through Standby Palo Alto firewall.
But when there's a interface failed or shutdonw on the interfaces where PaloAlto also connected, then once the ASA failover triggers and the same time Palo Alto also trigger its failover then both new active firewall and Palo Alto sending traffic through firewall.However we we cant all the interfaces of ASA also to connect Palo Alto and let the Palo Alto to inspect all the interfaces, but we need our ASA to work in a situation where any of the interfaces failed, the failover to work smooth the pass the traffic via either Palo Alto device.I just need to know is there anything tricky that we can configure on our ASA in this failover senario, or to confirm if there's no any workable solution to this situation.
I have attached the senario that I explained above. Just to emphasis the issue again, if any interface of Gig0/0, Gig0/4 or Gig0/5 failed on active firewall, ASA switching to standby firewall and act as Active, but Palo Alto still remains his Active state and the new Active ASA is not passing traffic via standby PA as its not detecting any of its interfaces as failed or unreachable..?
How to schedule automatic Xlate sessions cleaning in ASA5550. I want to clear few global nat sessions manually every week.Is there any way to automate that?
View 1 Replies View RelatedI have been told that if an access list is created with the suffix _access_in, that if the preifx is the name of an interface, then that access list is automatically bound to that interface, even if there is no explicit command doing that. I looking at the config of an ASA 5550.
example:
Interface is Production
access list is called Production_access_in.
Is that access list automatically bound to the Production interface, even though it does not show up in any other commands?

View 1 Replies View RelatedI have two asa 5520 firewalls. one at my primary data center connected to our production Internet feed, and one at my fail over data center connected to a backup internet feed. I was wondering if there was an easy way to keep the firewall rules in sync between the two firewalls. We have failover with our isp that will move our public facing address block from our primary site to our dr site in the event of a disaster so the ip addresses will not change if we were to have to fail over to the DR site. currently i just have to do any changes that i make on the fail over server but would like a way to at least simi-automat this if not fully automat this so that i can eliminate the possibility of human error of a change happening at primary but never getting don at DR.

View 5 Replies View RelatedI have a asa5520 with five Internet IP.One for the internet interface and the others are static maped to dmz hosts.

I called ISP to check,when ISP clear their router's ARP, the asa will lose the connection at the same time and then the ISP's router couldn't learn the ASA's MAC. After I 'clear arp' manually,The ISP's router can learn the ASA's MAC and the connection recovered,but the DMZ's cann't access internet still (of course,There is no problem between DMZ and ASA ,I ping the internet gateway from DMZ host and can not get any reply.).
We have 2 x ASA5520 and I upgraded this to 8.2.2 last year, I see 8.2.5 and now 8.4 is out. If we are having no issues, is it best just to leave it as it is? I can see a couple of features I may find useful in 8.2.5, but 8.4 seems like a huge jump and a risky one too.

View 3 Replies View RelatedI am trying to introduce an ASA5520 to my network based on the following diagram: ISP Internet ------> ASA5520 ------- > Cisco Router ------> LAN.

If i remove the cisco router and replace it by a swich, I can ping the ASA with NO problem.

By using Routing statements and statics I have been able to reroute specific traffic to the ASA5520 version 8.3 Now I need to inverse the 2 devices. The ASA5520 will be facing the Internet and the PIX will be behind it.Unfortunately the ASA5520 is refusing to route the traffic to the PIX. The access-lists are open accordingly and a NAT on the ASA has been created.

After that the secondary cannot join as a failover unit and shows in disabled status.We have the same model ASA & CSC module and each pair of them are in same firmware (CSC 6.6.1125.0 with ASA5520 8.4(4)1), when I shutdown both the csc modules, the ASA failover works fine.
I am using a squid proxy behind an ASA5520 firewall to collect the users to the internet. Squid is just necessary to log what is going on in order to find a quick solution when the internet slows down.
Considering that I have unlimited licenses and I would like to get rid of squid, I wonder if the ASA has some functionalities to track which websites are being used and how much traffic is generated. If there is not, I would like to know if Cisco offers a good product to replace Squid.
Upgraded an ASA5520 from 7.x to 8.4 in one step? Release notes for 8.4 state that you can "...upgrade from any previous release directly to 8.4..." I've read the previous version release notes and see the various changes in NAT etc that 8.3 made.

View 1 Replies View RelatedAny limits on the number of IPSec sessions an ASA5520 can support over a DSL connection?
Currently, as we increase the number of IPSec VPN tunnels, our LAN switches connected to the DSL/ASA start seeing CRC/input errors. Tried different LAN ports for both DSL/ASA connections - same reults (CRCs and errors). Swapped ASA for PC running 1 IPSEC w/HD video and no issues.
VPN connection bandwidth demand 50% of DSL capacity, so not exceeding DSL bandwidth. Errors get so bad that all VPN sessions drop - sometimes VPN sessions re-establish while other instances a DSL modem reboot is required.
cause of LAN switch connections seeing errors with 4+ VPN sessions established on ASA across a DSL Internet circuit?
