We are in the process of building a new DC and would like to know which is the recommended version of code to run on the following:
Firewall Services Module
Cisco ASA5580, 5550, 5520
ACE module
Looking for a recommended code on the ASA 5585x firewall. We ran into a bug (CSCtr24705) on version 8.4.2 where it rebooted the primary firewall. The bug has to do with modifying an existing ACL that's part of a custom policy-map inside a service-policy. If we upgrade to 8.4.5 (which has the previous bug fix in it), there is another major bug (CSCud70273) where if you use the packet-tracer input command on an inside interface it causes problems too.
I don't understand why packet-tracer input would have a bug associated with it when it's been around for a long time and we use it on a daily basis for troubleshooting. Is there stable code for the 5585x to upgrade to without running into possibly a major bug? This is our core firewall so there are no VPN tunnels on it. It's setup in active/standby failover in routed mode.
Anyway, here's the situation I'm trying to configure several VLANs on my ASA to uniquely allocate to contexts, the VLANs will be trunked from my VSS. Unfortunately I'm not clear on how to achieve this, the configuration guide for 8.4 talks about multiple contexts and routed setups all which don't appear to apply exactly. I've configured the port channel at both ends and I've configured sub-interfaces on the port channel and assigned VLAN IDs. These sub-interfaces are then allocated to the contexts to set 'ip address' etc. I've not been able to successfully test this configuration and I am concerned that it is incorrect..
View 1 Replies View RelatedI am having issues with PXE boot images for PCs cannot be loaded from remotely.The diagnosis revealed that SunRPC & TFTP were being inspected by ASA causing drop of packets.So I excluded these two inspections for the particular server behind the firewall. It seem to resolve the issue for instance but it crawled back again.
Is there a way that the inspection can be turned off for that particular server at the IP level?
We have an active-active pair of cisco ASA5580-20 with software version 8.4(1)9. There are 8 contexts on it (including admin and system). 1 context is active on Primary node and other 7 are active on Secondary node. User traffic is going through this 1 context (2 interfaces - inside to users, outside to internet) and there are peaks to 1.16M concurrent connections, max bandwidth is 1.25Gbps. CPU usage for this context in peak hours is 63%, but we noticed that when we run "show cpu usage context all" from system it shows that system context is using 25% of CPU and "Total CPU utilization" (form output of show cpu detailed - on system context) is 88% which is bad. In non peak hours - user context use 33.6% CPU, system use 14.5%, total CPU usage is 50.5% So, is it normal this cpu utilization on system context (system on Primary node)?

After initial configuration everything seemed to work great, however, as of a few days ago I can no longer view statistical information. I can attach to the devices without a problem, view and edit all configuration information but the dashboard applets do not pull or display any statistical info. Resource, Interface, and Traffic status all time out with the error "Lost Connetion to Firewall". The syslog info is not display rather the error "Syslog Lost Connection". My first thought was a java issue on the client. I have ripped out and reinstalled even back-revisioned to no avail. I'm to the point where a dumpe of the management workstation is the next step. I'd like to avoid that extreme if possible.

View 6 Replies View RelatedI am looking for the way to define an idle timeout for specific flows on an ASA5580 by using Cisco security manager. For ex I needed to define a specific idle timeout for connections beetween specific devices (Devices in vlan1, Device2 in vlan2).To test it I did following changes by CLI and it works fine. access-list L1 extended permit ip <@IP1> <mask1> host <@IP2> class-map CM1 match access-list L1 policy-map PM1 class CM1 set connection timeout idle 02:00:00
I try do do the same configuration with CSM in order to be able to manage each changes only by using CSM.So I defined Access control list, Traffic flow and then I define timeout in CSM --> PIX/ASA/FWSM Platform --> Service Policy Rules --> IPS, QoS and Connections Rules -> connections settings -> Traffic flow idle time-out. The problem is that each time I deploy the configuration with CSM I loose the timeout config line which is the most important for my application..
My current network setup has pix 525 firewall and for IDS i have 4215 box.As the utilization is high i am buying new ASA5520 firewall.
My query is
1 My IDS is end of support should i buy an IPS moudle with the asa 5520.is it recommended?
2 Other than firewalling what are the default features supported in asa 5520 like vpn,content filtering etc.
I have implemented ASA 5520 as the main firewall. The outside interface is connected to a cisco router and the router is connected to an ISP. I want to make my security system more secure. Which product is the best as the internet gateway solution. Which licenses are required for this one and what is the,cost for each license. Where can I find the DMZ diagram recommended by cisco ?
View 1 Replies View RelatedI have a pair of ASA 5510s configured in active/standby mode. I have already configured the fail over settings on the firewalls. Both firewalls are connected to a 2960G. I made a change to the interfaces on the 2960 to allow 2 mac addresses on each port. [code]
Upon testing failover via the failover active command, I get port-security errors on the outside interface for each device:%PORT_SECURITY-2- PSECURE_ VIOLATION: Security violation occurred, caused by MAC address aaaa.bbbb.cccc on port GigabitEthernet0/8. After a few minutes, the error goes away and I can then connect to each firewall. It seems that it still waits for the aging time to expire before allowing the other MAC address. Shouldn't the "maximum 2" setting allow for both mac addresses?
I'd rather not have to hardcode the firewall's MAC addresses on each switchport because I could see this causing problems for us down the road. Is there anything else that can be done?
We have 2 FWSM modules in each 6500 switches. 1st module is having 04 firewall vlan groups with 18 vlan interfaces in a single context firewall. All are working fine with no issues. Recently we create one more vlan on MFSC and add into the same firewall module. However newly created vlan inside the FW is not able to communicate with outside and also outside users not able to reach newly created subnet. But within the firewall zones (other interfaces) it can communicate. Once we did packet capture we noticed that its hitting firewall outside interface only and when we ping we got TTL expired error. we have default routes to outside and there's no any route inside as new segment is within the firewall (no any hop).
I guess there's no limitation on number of vlans that we can assign on one firewall eventhough there is a limitation for number of vlan-group which is 16 max (but we are within that limit).
Can any1 tell me wat is the difference between ASA-SM1 and FWSM.

We recently deployed a FWSM on our 6503-e boxes (w/ sup720). NAT is working (PAT) but the issue I am seeing is private traffic from remote sites is not being allowed through the FW. I was able to get the remote site to ping the FWSM itself (inside address), but no hosts behind it. Maybe an ACL issue? Also when I turn off NAT on the remote end, I can than access everything (We are NATng on both ends). Im a routing guy by nature so I will defer this to the security guys out there.

We have a pair of 6500s with Sup720 running 12.2(33)SXI3. Each has an ACE-20 (s/w A2(2.0)) and FWSM (s/w v3.2(15)). We have reached a limit on the number of rules we can configure on the FWSM, and have determined that we shall upgrade to 4.1(5), with ASDM to 6.2(2)F. A question has been raised regarding the s/w on the ACE-20 modules. Do we need to upgrade them as well?

I think I got a strange behavior on a context of my WS-SVC-FWM-1 (on a Catalyst 6509 running IOS 12.2(18)SXF17a) that is running FWSM Firewall Version 4.1(3). This context sends these log messages every ten minutes:
Jul 17 2011 23:31:16: %FWSM-6-302010: 0 in use, 0 most used
Jul 17 2011 23:31:17: %FWSM-6-302010: 2245 in use, 107133 most used
[code]...
If I issue the "show conn" three seconds later the log message, the output I got is: FWSM# sh conn 1041 in use, 107133 most used
In another context on the same FWSM the log message sent every ten minutes is just this one:
Jul 17 2011 23:31:17: %FWSM-6-302010: 1358 in use, 72503 most used
Jul 17 2011 23:41:22: %FWSM-6-302010: 1590 in use, 72503 most used
In this case there is no the log message where the "in use" field and "most used" field are 0 (zero). why does the context send the message with the "in use" field and "most used" field 0 (zero).
I have attached a drawing of our network. We have two 6509's connected to two Cisco 2811 (onsite) that the ISP owns. I am trying to get one side up and running before I worry about redundancy and so forth. For this reason I have set all the HSRP priorities to 110 on the left 6509. I have HSRP running between the ISP routers and V LAN 101 of the 6509's. This works as I can ping yahoo and Google just fine from the 6509 switch. I can't get from my laptop connected to V LAN 23 to the internet.
It doesn't even attempt to NAT as there are no translations. I have public address assigned by my ISP configured between the ISP routers and my 6509 on V LAN 101. I then have the public address assigned to V LAN 100. I configured V LAN 100 on the switch and V LAN 100 on the FWSM with the IP address in the drawing. I have my NAT statements and route in my FWSM according to the drawing as well. On the switch, I have a default route to X.X.12.19 which is the VIP between the ISP routers. I can reach anything on the inside of my network, including the old network addresses from V LAN 23.
1. Is it best to do NAT at the FWSM or should I do it on the MSFC connected to the ISP routers?
2. If I have to configure NAT at the FWSM, does this requires me to extend the public network down to the FWSM?
3. I'll take any examples you may have as I am stuck.
We run a 6500 with an FWSM with multiple security contexts as well as cascading contexts with a "shared V LAN" . There is a problem with regards to Linux machines and our shared network.
For example, we have three Linux machines in production, each in three separate V LAN's. For me to communicate to these boxes from one V LAN to another I must first ping the server. If I do not ping the server it will not bring up a connection like ssh or HTTP, etc. Below is the error I get from the FWSM that hosts the Linux server, but like I said once I ping the server the error goes away. We only have this problem with Linux machines, and it is a problem for all three of them. Is the FWSM having issues understanding something with all three Linux boxes? Below is the error I get at first, when I try to SSH from one V LAN to another V LAN with the Linux machine.

Deny TCP (no connection) from 10.255.12.109/22 to 10.255.1.30/63000 flags SYN ACK on interface inside.
Below is what happens when I initiate a ping to the Linux Server and then ssh again. Notice it builds the connection with no problem after the ping. During the ping it builds the dynamic translation, and then when I ssh it builds the TCP connection. Do you know why this could be?
