We want to make an upgrade of one of our customers' ASA 5520 (with failover). They have version 8.2 now and we want to get the more stable newest one. Can we get an 8.6 version? or we need an ASA 5500X for that one?

View 10 Replies View RelatedI have a server in a DMZ behind the ASA, connections to this server work sometimes and then fail others, so I dont think i'm looking at an ACL or NAT problem here.The syslogs report a SYN Timeout,I have taken a trace on the ASA, it seems that a SYN-ACK does come from the destination server within the 30sec timeout, but its not passed through the ASA back to the source ? there is one odd thing, what seems to be an out of sequence ACK from the destination which arrives before the SYN-ACK at the ASA, i'm wondering if this might be the problem ? This only occurs on the connections which fail, the connections that work, the destination responds quickly to the initial SYN, and the 3way handshake completes.

View 9 Replies View RelatedI 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?
I'm trying to install an ASA 5510 transparent firewall using ASA version 8.4(3)9 but I don't understand how traffic will ever pass through my firewall if both interfaces are on the same sub net(V lan) as the host and it's default gateway? The reason I'm doing this is were installing UAG (or Direct Access) and the UAG appliance need to have public IP's but still be behind a firewall (see attached diagram).
Looking at the documentation (which all seems to be for 5505's running 8.2) it almost seems like i need to have the transparent firewall 'in-line' to the ISP router?, but this router services another IP address range on another v lan for other (routed) firewalls (not shown on diagram) so putting it 'in-line' is not possible. Surely this can't be the case can it? If not how is it supposed to be cabled up and configured so packets go through the firewall?
How are asa5540 in high availability mode upgraded for their versions.

View 1 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.

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.
