We want to use ASA5520 but both Firewall have different CPU. One has CPU Pentium 4 2400 MHz and another has Pentium 4 Celeron 2000 MHz. Can it be configured for replica / failover?

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.
I have some LSA type 5, I want to change it from type 5 to type 3 before send to another Area, How can i do it?

Is there a way to find it out on ASA running 8.3?
I 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 2 Replies View RelatedI have a asa5520 with five Internet IP.One for the internet interface and the others are static maped to dmz hosts. It runs rightly until yesterday.Now it will lose the connection to the gateway many times everyday and the dmz hosts can not connect to internet any time. configuration(simplified):
!
interface GigabitEthernet0/0
nameif internet
security-level 0
[Code]....
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. The problem is I cannot ping the ASA from the LAN. I can ping it from inside the router. I already allow ICMP within ASA. If i remove the cisco router and replace it by a swich, I can ping the ASA with NO problem.
View 5 Replies View RelatedWe have 2 firewalls on PIX facing the Internet and connected to interface e1 (behind it) an ASA version 8.3 Both the PIX (Firewall facing) and the ASA are on the same subnet.
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.
i have my router connected to ISP then my router directly connected to my ASA5520....i use also ASA5520 as my DHCP Server and i was wondering with the DHCP Server function of ASA 5520 because if i use the ASA 5520 LAN ip ...all workstation will not be able to browse anything from the internet unless i use my ISP DNS IP which they gave me?

"Mate's service module (CSC SSM 6.6.1125.0) on slot 1 is different from mine (CSC SSM 6.6.1125.0)"
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?

View 3 Replies View RelatedI have a question about access-lists on ASA: (5520 running 8.4)Often I want to permit all traffic from networks behind an interface (let's say DMZ in this example) to Internet, but NOT to internal networks. Then I first configure a Deny from DMZ to all internal network and then a Permit to ANY. If I forget the first Deny I will allow all traffic also to my internal networks. Is it possible to configure an access-list that permit all traffic from a network to all networks that are reachable via a given interface? In this example: Permit all traffic from DMZ to all networks that are reachable via the Outside-interface? This should permit traffic to Internet and deny traffic to internal networks in one statement.If I specify the outside-interface as the destination only traffic to the interface itself will be allowed.
View 1 Replies View RelatedI've got an annoying problem with my ASA 5520.I have traffic going from the inside interface (security level 100) to the outside interface (security level 0) with a global PAT applied to the outside interface address for all inside traffic - and I can't seem to traceroute through the firewall.The ruleset is simple - basically, allow any IP from inside to outside. The NAT is simple - PAT all traffic unless exempted to the IP address of the outside interface.If I do the trace from my internet edge router it works fine - so I know it's not soemthing my uplinks are filtering - but if I do it through the firewall, I get perfect responses until the hop where it hits the firewall interface - then nothing.Is there something I am missing that I need to do to allow traceroute to just work with all the rest of the traffic?

I can no longer SSH to a primary active firewall. It had all of a sudden stopped working. However I am able to SSH to the secondary standby firewall without any problems. I did try to regenerate the RSA key on the primary fw, but still unable to connect. The only way I can connect to it is by using telnet.
I ran the "show asp table socket" command and I'm seeing port 22 listening on the primary IP address (not the standby), foreign address is 0.0.0.0:*. I did a packet capture on port 22 on the inside inside, seeing my request hit the fw and then right away a reset back from the fw.
version 8.2.(5)
model ASA5520
I'm hitting a bug in the software version I'm running? Or what else can I check before rebooting the primary fw?
We are planning to upgrade IOS on a 5520 pair, from 7.2.4 to 8.2.4, and cause minimum outage. And according to the documentation, we can do the zero downtime IOS upgrade by failing over to the standby ASA and back.

So, can during this process, can we go from 7.2.5 to 8.0.5 (last maintenance release), or do we have to move to 8.0.2 first ?
I'm trying to setup a zone behind my firewall with complete publicly routeable IP addresses for 3 servers. The reason I'm doing this is I am in the network setup stage of an OCS implementation, and OCS connections don't behave well with NAT.
My device is a ASA5520. I have an internal zone, and a dmz zone. These are done via standard NAT configurations.
My question is this:
Is it possible to setup connectivity to the outside with internal servers that have Public IP's directly on their NIC's? Another little detail of interest is that this ip space is seperate than the one that's on current Outside interface facing our ISP. However we own both address space.
I am in the process of setting up the ASA5520 with the latest 8.4 firmware latest Anyconnect 3.0.
Unfortunately, the internal memory is sufficient enough for the ASA ASDM only. It says not enough memory when I tried to tftp the Anyconnect pkg.There is a external flash slot at the back of the ASA, I've inserted a 256mb CF card but when I do a show disk1: it shows
