Cisco Firewall :: NAT RPF Check Failure PIX 8.2 OS
May 2, 2013
i know in Cisco PIX til 8.2 OS, if i have Nat control disabled and ACL permitting connection from Low Secirity ( DMZ ) to High Secuurity (INSIDE) then connectino should be successful, and i dont need any STATIC identity nat of inside IP to be created.
But i have Cisco PIX 525 with Version 7.2(2) Which is not allowing connection from DMZ to INSIDE , although nat control is disabled. and giving RFP check failure, any thought?
PIT525PIXINET# sh running-config nat-control no nat-cont
packet-tracer input dmZ tcp 192.168.85.4 65000 10.34.21.25 3389

ASA running 8.2(5).When I enable ip spoofing on my network interfaces I see this getting logged:
Deny UDP reverse path check from 10.100.100.102 to 10.100.100.255 on interface SPECTRA-LAN
This is because interface SPECTRA-LAN (VLAN50) is the interface connected to the network with ip 10.100.100.0/24 but the interface do not have a ip address so it does not exist in the routing table I believe?However interface INTERN do also belong to network 10.100.100.0/24 which also is the management interface and the default route for hosts in network 10.100.100.0/24, but has no vlan.
1. move the management0/0 to SPECTRA-LAN and give SPECTRA-LAN ip 10.100.100.1?
2. give SPECTRA-LAN a ip address in the 10.100.100.0 range?
My routing table and interface list is:
Current available interface(s):
DATA-BACKUP Name of interface Redundant1.10
DMZ Name of interface Redundant1.900
GUEST Name of interface Redundant1.990
HOSTING Name of interface Redundant1.100
Infrastruktur Name of interface Redundant1.20

Does ASA 8.4.3 check the source IP address of a DNS reply and drop it if the reply address is different to that in the query?
Customers DNS server does this due to a recent change, their server now has a virtual address, but replies are sent from its physcial address. This is temporary. Their PIX is happy with this.
Replace the PIX with the ASA, DNS fails, the only reason I can see is due to the way their internal DNS operates.

When we setup a connection between two hosts we receive the message "TCP checksum incorrect" , This is between a settop box on the outside and a server inside the firewall. This STB used to communicate with the server on port 443 which is NAT-en to port 12697.With a new settop box image which uses on the inside and outside port 12697 we receive this TCP checksum incorrect on the Firewall with wireshark.
Strange is that on the outside of the firewall we see an MSS of 1460 and on the inside it is 1380 (don't know if there is a relation with this and the issue we have)

Is there a newer tool for current versions of Checkpoint to ASA 8.4? I notice a lot of similarity between checkpoint and 8.4 now, but I still have to do it all line by line which has become a PITA.

I am looking for for details meaning of license because I cannot found the details install. The license call
FLASR1-FW-RTU(=)
that is used to enable the firewall function in ASR 1000 series. But I don't clear about what feature inside, it is because it only show the "firewall" from website. Is that same as IOS firewall?

I have 7604 router with FWSM module in module 3.First of all the FWSM CF has been damaged, not physically. I bought the new same compact flash (size, partnumber, etc.). Downloaded the software 3.2 for FWSM, and ASDM from Cisco website. I realized that the procedure of creating new CF for FWSM is quite diffucult: creating 1-5 partitions, where 1 - is MP, and 4th - application partition. According to cisco documentation - the default boot partition is the 4th, so I partitioned from 7604 the CF into 4 partitions (partition disk1: <1-4> maximum) and copied the software and ASDM to the 4th partition (disk1:3:). Removed the CF from the router and put it into the FWSM module.

I have two ASA 5520s in Active/Standby. I try and test this quartely to ensure it is working correctly. Everything works fine, except I have an issue with one interface. When doing a show failover, it shows the interface as failed on the secondary unit, and I am not sure why. It shows it as normal on the primary.
This host: Primary - Active
Active time: 9277305 (sec)
slot 0: ASA5520 hw/sw rev (2.0/8.2(4)) status (Up Sys)

I am using a Pix515E with 8.0(3) and 128MB RAM. It ran OK for months but has recently had several episodes during which it produced streams of memory allocation failures (syslog 211001). When in this condition I could not log into the VPN. It was still operating but some users were having problems and I eventually had to restart it.
The traffic load is typically 10Mbps, and the max number of connections is around 10,000 but typically 5,000. The CPU usage is 10%-20%. There is 1 VPN with normally 1 client. The memory usage is always high, between 115MB and 120MB but during these problems it creeps higher.
Why might the memory usage be so high when my network load is quite light for the 515E? What circumstances cause the memory usage to increase during operation? Is there anything I can do to prevent the memory usage increasing to the point where the PIX crashes?
I have a second 515E with 8.0(4)32 and 64MB RAM, loaded with the same config. I have not had this one in service, but off-line it is using 53MB of memory. If the spare pix needs 53MB to load the firmware and my config, why does the other one use 115MB?

Ive got a virtualised firewall running 3 security contexts in routed mode. What am experiencing is that i cannot connect to an OUTSIDE host through the security contexts. From the firewall itself i cannot ping the directly attached host on the OUTSIDE interface but i can ping the directly attached host on the INSIDE interface. When i reload the firewall box, the first ping to the OUTSIDE host would be successful but subsequent pings fail and thus total connectivity is lost.
I even tried upgrading to ASA version 8.4(1) but still the same.

Firmware asa805-k8 was installed and saved on an ASA5505. Upon power failure the ASA5505 reverts to an older firmware, asa724-k8. 1) Is it normal for ASA5505's to revert to older version upon power failure. 2) ASDM/web browser doesn't work using IE--username and password brings to empty screen. how to revert back to later image.

After upgrading an ASA5520 from 8.4(1) to 8.4(4.1) I ran into the following trouble:
Asymmetric NAT rules matched for forward and reverse flows; Connection for tcp src outside:192.168.149.21/53 dst inside:192.168.37.123/53 [code].....
All the subnets mentioned above are connected via VPN.

Cant seem to get around this one yet. I have a remote ASA that I can VPN into. It has 2 dmz's, outside and inside interface configured.
Inside subnet is 192.168.11.0 / 24
DMZ2 is 192.168.13.0 / 24
VPN client pool is 192.168.15.0 /24
I login in fine. But have no access to the DMZ2 subnet. I get the failure listed above.

I am trying to lock down the VPN access on my Cisco 5520 ASA's whereby I wish not to allow users to SSH access etc on servers running on the same interface that they are VPNing into.
I did not originally configure the ASA and so I am slightly confused by some config on it. Currently when I attempt to PING a server within the same interface as the VPN network I get the following error in the logs below.
5 Jul 05 2012 09:45:15 305013 monitoringsystem Asymmetric NAT rules matched for forward and reverse flows; Connection for icmp src dmzAHdata:VPN IP dst AHdata:monitoringsystem (type 8, code 0) denied due to NAT reverse path failure
As a workaround I created a NAT exempt rule which then allowed traffic to the server in question however I wish to limit the traffic to only ICMP and when I do this in the firewall it does not take affect. Is this because of the NAT exempt rule?

I have 2 asa 5520 firewalls including and 1 AIP-SSM-10 module in each of them. the configuration is set using active/active failover and context mode.
Both of them run individualy the IPS module. The IPS is configured using inline mode and fail-open option. However when one of the module fails and the state is changing from up to init or anything else making the IPS to fail then failover is detected and ASA consider it as failover and bounce context to the other unit.
IPS soft is 6.0(4) and ASA soft is 8.0(3)
I have checked cisco doc and it is confusing to me. it says: "The AIP-SSM does not participate in stateful failover if stateful failover is configured on the ASA failover pair." but it really does participate. Running is not really an option because of production network impact matter..

I have a Cisco ASA5520 that we are going to use to allow users to connect to our network via the Anyconnect client, I have authentication set up to validate against AD via LDAP, but was wondering if there were any way to set up the profile to check the PC before they log in....we do not want users using their home PCs to attach to our corporate network, only PCs that were issued to them by the company. Nothing is jumping out at me in the config, we are running some fairly old sofware on the boxes (ASA - v8.2(2), Anyconnect - v2.5.3046) I plan on upgrading the Anyconnect to v3.1 but will probably need to keep running the 8.2(2) version on the ASA due to support issues.
