I understand from the Cisco documentation that a service-policy applied to an interface on an ASA 5500 series firewall, will override the default global service-policy. However, I am not clear on whether it will override the entire global service-policy, or only the parts where they overlap. In other words, would the resulting service-policy on the interface in question be just what was applied in the service-policy on the interface, completely replacing the global service-policy? Or, would it be a combination of the global and interface service-policies, with the interface one taking precedence where they overlap?
if I wanted an interface to have the same service-policy as the global service-policy plus on other item, can I just add the one item in a service-policy that I apply to the interface, or do I have to replicate all the items from the global policy, plus the one additional item, and apply that to the interface.
Can any ASA 5500 in particular the ASA5510 firewall support jumbo frames (i.e. greater than the default standard 1500 Bytes frames)?. I plan to use the ASAs to setup a point-to-point IPSec tunnel and need an Application frame of 4Kbytes intact and not segment it.I have done little checking on the Cisco Website and see it mention of Jumbo frames on the 5580 on 10Gig interface but didn't see mention 5510. 5580s are way over-kill and expensive for what I need is to run a mission critical one IPSec point-to-point with maximum of no more than 100Kbps so 5510 is perfect for me but not sure if it can carry the jumbo frame?
On the routers and switches it's the MTU settings and they are configurable per interface and I am OK and the circuit is T1 which the Telcos said it's OK since it's physical layer so the only unkown is the firewall.
I have two 1811's connected in a lab using a ipsec vpn tunnel (using a switch to simulate an internet connection between them).I am trying to configure one of the routers as a ZBPF just to allow a remote windows login (DC on the firewalled side, workstations on the other side).I'm trying to verify that the zbpf is working, but it doesn't seem to stop anything. I had match icmp added to the class-map, but took it out to test if icmp would fail. It didn't. Basically, I don't think the firewall is working at all. Any thoughts on how I can configure this so that the policies will work between zone-pairs?
Here's an quick drawing:
Here are the configurations:
Local router: hostname sdc-1811-LocalLab ! boot-start-marker boot-end-marker ! no aaa new-model ! resource policy
I purchased the license P/N: ASA-CSC20-250U-1Y with Description: ASA 5500 CSC-SSM-20 250-User License Only Renewal (1-year)
But I had a mistake because I need support to 500 users. Now, to solve my mistake I want to know Do I can purchase another ASA-CSC20-250U-1Y to provide the 500 users suppor?
I mean, ¿are two (2) ASA-CSC20-250U-1Y equivalent to the 500 user license listed below?P/N, ASA-CSC20-500U-1Y with Description: ASA 5500 CSC-SSM-20 500-User License Only Renewal (1-year)
I have multiple customers with either 877 / 1801 routers with dsl issues, we keep dropping sync , get slow speeds etc,
I have already updated to firmware 4.018, in some cases it has resolved the issue in others it has not, BT say their lines are ok, but still i keep getting issues.
Cisco 6509 modular IOS getting high cpu in interrupt but the switch process switching is still less. Any sugeestion what could be the problem?

I would like to know can we configure vlans with cisco 1721 Modular Router? Is it Possible to configure lan environment with the vlans configured in 1721 router without a managed switch?
I have two ASA 5510 with Security Plus license and Shared SSL VPN licensing enabled.
The problem is that the client get “Session could not be established: session limit of 25 reached” but ther is only 6 ssl vpn user connected with AnyConnect.The software on the firewall’s is 8.2(1)Is there any BUG in this software related to this problem?
I understand that when host A 10.0.0.1 wants to connect to host B192.168.1.1 its going to be translated to 170.66.53.1 when host 192.168.1.1 wants to connect to10.0.0.1 the same entry will change the destination when the packet hits the asa from 170.66.53.1 to 10.0.0.1, is that correct ?
How can I configure police-based nat to allow ICMP-only traffic on asaos 8.4.1 or 8.3?On 8.3 it was very simple:global (outside) 1 interface ,access-list outside_nat_outbound extended permit icmp any any,nat (outside) 1 access-list outside_nat_outbound.
I have devices on Inside interface of ASA that need to get to Internet to get ntp. Hence I want to set up dynamic pat (interface overload) which 8.3 style would be
But I need to limit nat to only Internet destined traffic on ntp port not all ports for traffic from 192.168.1.250.I'm not using this nat set up to control outbound access - I also have incoming RA VPN tunnels to the box and traffic from these sources need to be able to get to 192.168.1.250 and the above simple set up would break that access as all traffic involving 192.168.1.250 would get nat'd
Reading the doco I've sent myself round in a loops trying to figure how you are meant to do such a " Dynamic Policy NAT (overload)" call it what you will config in 8.3
I have an ASA 5500 Firewall. I need to figure out how to log all events using Port 25 to determine if there are any rogue devices on our network. I was trying to figure out how to do this via the Real-Time Monitoring (filter) but have had no success.
I have an issue with a Cisco ASA 5520. It seems to block some emails incoming from some recipients. The sender's mail server clearly reports my ASA as cause of the problem (see attached image). Unfortunately I have not the logs about that event and the time frame to close this issue is very narrow.
We have to set up voip for our network(for 50 phones not he cisco phones).
I need to just the route the voip traffic to gateway address of telephonic company(1.1.5.7) where they provide us the connectivity for the setination call.
What sort of protocols should i have to enable in pix i saw the concepts like sip, h323, ras, skinny.
We are using only voip for asa and no data or other traffic should be allowed.
inside adrees: 10.10.10.0/24 for all voip phones outside:121.21.22.1 telephoneic gateway: 1.1.5.7
We are now using image 8.0(4) for my ASA 5510. Later on, I would like to upgrade the image to 8.4(3).May I have to know what difference for those images, what should I take care of the script?
Is it really the case that the ASA will not generate ICMP Host Unreachable messages for sub nets connected to any of its interfaces (in breach of RFC1812) as claimed here: [URL]
I'm investigating a situation where an organization uses ASAs to control traffic between different v lans in their internal production systems as well as Internet traffic. They are having problems with internal load balancing because the ASAs do not (as currently configured) generate Host Unreachable packets. Can this be changed in the configuration or not? I have to say, if it can't then I'd urge them to find something else to route between their internal sub nets.
I am pretty new to cisco and the learning community forums is truely one of a kind.Actually, I work on a company which deals the Cisco products, Routers/Firewalls/Switches and stuffs. I am sure you get the picture. What confuses me is the product licensing of ASA5500. To be more specific, we are proposing certain things. And that came with the product pricing sets and all. But I amn't having a clear picture on ASA 5500 Strong Encryption License (3DES/AES). Does that come inbuilt(free) or should there be any pricing behind that!?
How can i determine the current PPPoE session duration on ASA 5500 Systems? If i use the different CLI commands like "show vpdn session state / show vpdn session pppoe state" the output says:
State: SESSION_UP Last Chg: 593595 secs.
The ISP is forcing a reconnect every 86400 seconds, so the value can't be the actual duration of the pppoe session. Does it only indicate the link duration to the attached modem or interface state? Is the only way to detect interruptions of the pppoe session with debug and syslog?
On the inside interface and network, we have a server at, (as an example) 192.168.87.1, which acts as an email server.
The outside ip address of the ASA is, say, 200.0.0.1.
The ASA directs any imap requests from the outside interface to 192.168.87.1, which works fine from the outside. Users simply open up email, and collect emails etc.
When they come inside the office, their machine of course attempts to contact the ip address 200.0.0.1. the ASA knows it is outside interface, so they are unable to collect emails.
that any internal IMAP requests from machines on the inside to 200.0.0.1 are directed to the machine inside on 192.168.87.1?
i'm having issues with ASDM 6.3 on my ASA 5500.When i try to add a policy under firewall --> service policy rules (Add Service Policy Rule Wizard - Rule Actions), i'm not able to add a netflow policy as I'm not presented with a dialogue box after I press "add".i've tried this from multiple computers mac os and windows.
have a Cisco ASA that I am trying to configure in a unique way, I want it to perform a variety of tasks;
VPN SSL VPN Tunnels Firewall Inside to Outside via versa
But the difficult task, is creating a DMZ with devices that are assigned fully routed IP addresses from our ISP directly, these are H323 and SIP devices that cannot use NAT, and must have a fully routed IP address assigned to them.
Obviously the problem I have with the Firewall in its default routed mode, is that it wont allow me to overlap IP addresses on the outside interface with the DMZ interface.
Could the Firewall be configured for Transparent mode between Outside and DMZ, but Routed mode between Outside and Inside?
