I'm trying to configure an ASA 5520 with cut-through proxy feature. The user is required to be authenticated when trying to access an outside resource from the inside. This is a test lab before it is implemented in production. [code]

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.

I'm hitting a bug in the software version I'm running? Or what else can I check before rebooting the primary fw?

-INSIDE to OUTSIDE is working fine. (through ASA)
Below is the configuration from my PIX (where everything works just fine) as well as the one on the ASA (where there is a problem), what could be the cause?In the below case the DMZ hosts from 11.1.10.0 aren't able to access SMTP services (through ASA) and the OUTSIDE users aren't able to access DMZ web server (11.1.10.40) through ASA, this all just works fine with PIX.

View 7 Replies View RelatedI have a Cisco ASA5520 that I have setup to allow a GRE tunnel through from a router at site B. This all works fine when I use the below NAT with associated router object on the inside
object network SWTEST nat (inside,outside) static interface
My problem comes in that this kills off my Cleintless VPN connection to the same firewall, I changed my NAT to point at another of my statically assigned IP addresses, and then nothing works. Can anyone help with what I've done wrong, or what i should do? My rule base allows any GRE in from the source, and rules all look fine.
ip inspect firewall should be performing no inspection on traffic traversing an IPSec VPN right?

View 2 Replies View RelatedASA5510, ASA 8.0(4), ASDM 6.1(5), this is a productino ASA with plenty of lookups working through its 3 interfaces - outside, inside, dmz. The problem is a new use. I've segmented a switch on the inside network with a VLAN, and have a workstation routing through the switch to the default VLAN where all other hosts on the inside network reside so far. The ASA inside interface is the default gateway for the inside network. My test worksttion can PING inside hosts, so the static route is OK.

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.
I have two questions about ZBF on ASR1000 with Firewall and Flexible Packet Inspection license:
1 is IPv6 supported?
2 can I use police action in an inspect rule? I want to limit some protocols to low bandwidth. There is no police command in ZBF policy map.
I want to block some social networking sites using ASA 5510-CSC-SSM, As I searched and come to know that ASA 5510 can't inspect and intercept for https traffic because it is encrypted while traversing throught the ASA. I want the ASA to make functioning for https too, not only http. Can i perform this task by updating any software on existing device?
View 2 Replies View RelatedI have a strange problem in my ASA 5510 firewall. I turned on HTTP inspect policy to block certain URLs, but that destroyed svn communication. Interestingly, if I use simple web-browser to access svn server - it works, but any svn-client requests fail with an error "Could not read status line: An existing connection was forcibly closed by the remote host". I did some packet sniffing, and discovered that with HTTP inspect off the Webbed request is answered, but with HTTP inspect on it is rejected with an error unauthorized.

I am trying to configure my ASA 7.2(4) to inspect SCCP traffic from a CUCM v7.I have been advised that the ASA device needs to support the version of Skinny I am running.What version of Skinny does ASA 7.2(4) support? How can I find out what version my phones are using?
View 3 Replies View RelatedWe are currently looking at design models for a Multi-Tenancy solution.The firewall layer will be 2 X ASA's running 9.X to take advantage of VPN's in multiple context mode and mixed L3 and L2 contexts.
We will be delivering services through multiple L3 contexts (between 2 and 5 L3 contexts for services) and 1 transparent context for customers infrastructure who will then have virtual firewalls for NAT's and VPN's etc withing their own environment.
I am not very experienced with IPS so my query is; if we were to get an IPS license for both ASA's how would the IPS fit in, can we use it to inspect traffic for all the L3 contexts and the transparent context?
I have 2 ASA 5510 firewalls at 2 different sites. Both running on version 8.0.4. Users are using an Instant Messaging type of application provided by a local telco here which is able to send and receive SMS using SIP (from the packet capture that I've done).
When users use the IM in site A, they are able to send and receive text messages via the IM from behind the firewall. However, when the users are in site B, users are able to send out text messages but not able to receive them.
I noticed that when I remove "inspect sip" from site-B's global policy map, users from site-B can successfully receive text messages. I have confirmed that it is the firewall that drops the packets as I have captured the inside and outside interfaces of site-B's ASA and I can see the incoming sip "request: MESSAGE" packet on the outside interface but I do not see the packet exiting the inside interface.
I have cross check both firewall configurations, and I do not see anything suspicious commands relating to sip that might cause this issue. Is there any command to troubleshoot why the sip inspection is dropping the sip packets on site-B?
I have seen this a couple of times on two different routers. One is a 3745 and another a 1811 running 12.4(15)T4 and 12.4(6)T11, respectively.
When we have IOS firewall running (either IP inspect or ZFW), we will experience intermittent slow HTTP connections.
Symptoms include page timeouts, CSS not loading and just overall slow performance. Disabling the inspection cures the issues.

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.

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.

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.
