Cisco Firewall :: ASA 5520 / 5550 - Cannot Upgrade To 8.3
Aug 7, 2011I have a couple of ASA5520 and ASA5550, and I wanted to know if it is worth it to upgrade the software from 8.2(4) to 8.2(5)? Because of the RAM I cannot upgrade to 8.3 for now.

Jan 3, 2013Is it possible to import the config of a 5510 to a 5520. Trying to replace two 5510's with 5520's and wondering is there a way import the existing config files for the 5510's into the 5520's?

May 21, 2012I'm attempting to configure two ASA 5520 for active/standby failover.When I enter the “failover” command to enable the config on the primary ASA, the entire routing table disappears.There is no routing process running, only static routes are configured.
Is this an expected behavior of the failover process and if so, how long should I wait for the routes to come back?
Cisco VPN :: 5520 / 5550 - VPN Using Outside Ip With NAT?
Aug 13, 2012I'm trying to setup a tunnel from our Cisco 5520 to a 5550 using one of our external ips natted through this tunnel. For some reason traffic that should hit this tunnel goes through global nat. Here is the configs I have for this tunnel:
access-list policy-nat extended permit ip host 66.77.88.170 host 1.2.3.4
access-list Outside_cryptomap_60 extended permit ip inside-network 255.255.254.0 host 1.2.3.4
access-list Outside_cryptomap_60 extended permit ip host 66.85.99.170 host 1.2.3.4
[code]...
If I ping 1.2.3.4 from a inside ip host I see in the logs that it uses 66.77.88.136 as the NAT and not 66.77.88.170. Do you see something wrong with this configuration?
Cisco Firewall :: Migrating Netscreen Firewall To ASA 5515 Version 8.6?
Mar 5, 2013I am currently migrating a netscreen firewall to a asa 5515 version 8.6 The issue is setting up the management connectivity.
basically the management IP of the cisco asa is not advertised. But, we want to route a management IP through the management interface to interface Gi0/2.
so IP of management interface is say - 216.10.100.10. and the IP of the inside interface is say - 198.1.1.10/24 on our router we have a static route sending 198.1.1.0/24 to next hop of 216.10.100.10 (management interface of cisco asa).
On the Cisco ASA can I send the traffic to the inside interface and manage the firewall via ssh that way?
Cisco Firewall :: Migrating To New ISP - ASA 5510
Jan 4, 2012I currently have the following set up (excuse my quick drawing):
--------------Vendors VPN Router----
| ------Cisco 3000 VPN------ |
| | | |
Private Network-------ASA5510---------Pub Switch------Cisco Router 2x T1
I've been tasked with migrating to the new ISP, which provides us with Cisco ME-3400E switch and /26 public subnet. I currently have 15 static NATs and 14 L-2-L VPN tunnels configured in ASA. Is there a way to configure additional Outside int on ASA and use it to migrate the existing VPN tunnels and static NATs? I'm trying to avoid downtime and hope to do it step by step. I'm thinking about adding additional Public switch, so I can also migrate vendor's router and VPN concentrator, which need to be in parallel to ASA. Assuming that this is possible I'd would like to do the following:
1.Configure and connect additional Outside Interface on ASA - public IP address and ACLs
2.Connect it to additional "Public switch", which would be configured with public IP address and connected to new ISP's Cisco ME-3400E.
3.Migrate my VPN tunnels and static NATs.
4.Migrate vendors equipment/VPN concentrator
5.Update my global NAT pool
6.Shut down old ISP
Cisco Firewall :: Migrating PIX Configuration To ASA 8.4(2)

I noticed the "boot system flash:" and "asdm image flash:" command references the old PIX files. Do I need to update these or will they be updated when the ASA reboots with the new config?

View 3 Replies View RelatedCisco Firewall :: ASA 5515X - Config Loss After Primary Firewall Reloaded
Sep 23, 2012I have a strange issue which happened to me last weekend with two ASA 5515X on version 8.6(1)2. There was a planned power shutdown which only affected the primary firewall. Failover was configured and running successfully. The configuration was also saved after every change made. After power was shut and primary firewall went off the secondary took over like it should but unfortunately all configuration was gone. We immediately powered on the primary again but also this one lost the configuration.
While reconfiguring the firewall we ran into another problem. The devices won't pair although it was the correct configuration. After three times removing and adding the same failover configuration the devices accepted the failover and worked together again.
I went through the bug toolkit and white papers regarding ASA 5515x and this particular version but were not able to find anything.
Cisco Firewall :: ASA5540 - EAL4 Transparent Firewall Config
Mar 14, 2011I am configuring an ASA5540 firewall for a client, only difference to usual being that it is to run in Transparent mode. I have looked through for an EAL4 transparent firewall config guide but found nothing and therefore assumed that the usual one would be used.The clients security bod has now come back and insisted MAC filtering should be used but I can find no reference of this anywhere. Does MAC filtering is required to make a transparent box EAL4 compliant and if so where I can find documentation supporting this?

Jan 31, 2012we had just installed our ASA 5550 with IOS 8.0(2) a couple of week ago.
2 interfaces from each slot are being used ie 0/0 for Branch users comming via MPLS cloud , 0/1 for internal LAN users comming form Core Switch & 1/0 for Server farm LAN , 1/1 for Internet (outside)
the first 3 interface are considered inside with sec set at 100 while the 1/1 is outside with sec at 0.
Last night it suddenly started dropping all connections without any warning or any noticible log form the ASDM logging.
the connection drop would happen for 2 - 3 minutes and would work fine for the next 15 minutes or so..
after conencting the console , we found out that the IOS would suddelny go abrupt and show this display ...

Cisco Firewall :: 5550 - How To Do NAT Exemption With V8.4
Oct 4, 2011I have looked in the books I have (Cisco ASA, PIX and FWSM; ASA 8.0) and googled a good bit but can't seem to find any specific mention of how to do NAT exemption with v8.4. It seems NAT exemption (NAT 0 access-list) was deprecated. Using ASDM, there's no corresponding menu item for this that is obvious.
We have public addresses inside the ASA and want to allow in/outbound connections using these IP's without NAT. The ASA is a 5550.
Cisco Firewall :: ASA 5550 IPv6 Compatibility?
May 21, 2013I need to understand if ASA 5550 ver 8.2(1) is comptible with IPv6, if not what is the upgrade path to make it IPv6 compatible. The requirement is dual stack of IPv4 and IPv6 should run in the same HA cluster and later will shift IPv6 completely.
The existing infrastructure is equipped with ASA with HA Active/Active mode. The command output for required details are attached here in txt mode.
Cisco Firewall :: High CPU Utilization On ASA 5550?
Mar 10, 2013I have Active Standby ASA5550 setup with VPN premium license. A few days back we had a requirement of SSL VPN connection for and we got a temporary from Cisco for same, this license expired and the ASA reverted to it's original license. 3 4 days after this we saw a sudden increase in CPU utilization (upto 90% + -5%) on the ASA during production hours but were not able to figure out the reason, in order to restore the services we failovered the firewall to secondary and everything worked fine. We were suspecting one of the following but there were no logs for any of this
1. The ASA hardware was haivng problem
2. Some client was doing a DoS attack to bring down the ASA (no logs for this as well).
We took a downtime to look further by failovering the ASA back to primary and it worked fine without any issues ruling out the 1st option. We also came across a licesing doc [URL]
Downgrading any license (for example, going from 10 contexts to 2 contexts).
# Note If a temporary license expires, and the permanent license is a downgrade, then you do not need to immediately reload the security appliance; the next time you reload, the permanent license is restored.
As per this doc, sooner or later a restart was required on the ASA. We restarted secondary ASA and everthing was fine but when we restarted the primary ASA by swtiching over to secondary some of the server (not all) in the DMZ stopped working (even ICMP unreachable) and only came back to normal when the primary ASA was restored and working fine (with failover).
The reboot was done by shuting down the physical link between the Core switch and ASA inside individually.
I am not sure what could be the issue that the servers in the DMZ wen unreachable.

Cisco Firewall :: ASA 5550 Sending Reset With TTL Of 255
Oct 3, 2011I have the following problem, right now we have an ASA 5550 connected to the client´s side. A reset is being received on the client´s side, but when we run the sniffers on both extremes of the network, we can see that the reset is not being sent by the server´s side.
We have narrowed it down to the 5550 ASA, but have found no bug that matches the description.
The characateristics of the reset packet are the following:
- It is the only packet with a TTL of 255.
- Both server and client have very different window sizes, and the reset packet even though has the server´s ip and port as source of the packet, it has the client´s window size.
- It has a correct ack number.
-Before the reset is received, there are a couple of retransmissions of the last packet sent.
- We´re handling a VPN tunnel between both servers.
