Cisco Firewall :: 5520 Why Does Dynamic Policy NAT Rule Apply
Jun 4, 2013
we have a nat exemption rule for 10.0.0.0/8 to w.x.y.z followed by some static nat rules and then dynamic policy nat rule for 10.0.0.0/8 to w.x.y.z natting to IP a.b.c.d.When I do a packet trace from 10.10.10.10 to w.x.y.z, it shows the packet first matching against the nat exemption rule, and then immediately afterwards it matches the dynamic policy NAT rule. The static nat rules are being successfully bypassed (which is what I want), but why does the dynamic policy nat rule apply if an exempt rule has been hit already? An actual test between the IPs above reflects the result of the packet tracer as well (IP a.b.c.d is seen on server w.x.y.z).We are running the following software on an ASA5520.

I have configured the primary firewall every thing seem to be fine, And we have configured fail over device while config is getting replicated to the fail over device we are getting below error.
ERROR: Cannot add policy to rule engine
ERROR: Unable to assign access-list LAN_out to interface inside
IOS and Model are same.But all the config got replicated from primary to secondary but except the one access group command.
access-group LAN_out in interface inside.

I am trying to add 89,462+ access list rules to an ASA 5510 running 8.2(5). I have added all the rules to an object group and when I try to apply the access list to an interface it gives me the following error:
ERROR: Cannot add policy to rule engine ERROR: Unable to assign access-list wan-out to interface wan
I have not tried not using an object group and just putting the rules in the access list. I want to be able to add to these rules if needed easily.
I think it's clear that i have exceeded the rule limit for the ASA. So my question is, what is the rule limit for an ASA 5510 and which ASA could I purchase that would handle this amount of rules?

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
-object network obj_NTP-DEV
-host 192.168.1.250
-nat (INSIDE,INTERNET) dynamic interface
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

ASA 5520 to get it to authenticate VPN users against and Active Directory environment plus allow management access as well. I created a Dynamic Access Policy on the ASA stating that if you are a member of the Active Directory group "Managment" the continue. I chagned the DefaultAccessPolicy to "Terminate". So with that, VPN users cannot connect because they are not a member of that group, but the access to manage the ASA is allowed because of that policy.Is there a way through using Dynamic Access Policies that I can allow management access (SSH, ASDM, etc) by matching to a group membership and will allow normal users to VPN in successfully but not allow them access to managing the ASA?

I am attempting to allow traffic from one vlan to another.Vlan 1 is on Interface 0/2.vlan1Vlan 2 is on int 0/3.vlan2Each vlan can communicate inside it's own vlan, and the gateway on each responds to vlan specific clients My problem is that I am unable to communicate between the two vlans. Using the ASDM packet tracer tool, I find that packets are denied by the default rule (on the second Access List lookup). It appears as if the packet never reaches the other interface. The access rules are set up to allow traffic from one vlan to another (inbound), on both interfaces. Testing from either vlan to connect to the other fails. Below are the accee-rules for each vlans. Once I get basic connectivity working.

After upgrading to 8.4(2) and ASDM 6.4(5) I seem to have an extra access rule duplicating an existing rule, this is only visable through the ASDM. When using the CLI you can't see this duplicate rule.
I therfore get the following warning everytime I make a config change using the ASDM [code] If I delete this rule it returns everytime I launch the ASDM!
I also have extra config under Firewall>Configuration>Public Servers that I didn't have before. If I delete it, again it returns.

I'm running into this issue on an ASA 5520 running version 8.2(2)9 and ASDM version 6.2(1).
I have an ACL denying traffic to a certain IP range and the logging level set to Debugging. The hit count is rising quite rapidly but when selecting "Show Log" the Real-Time Log Viewer opens with a value of 0x13d0ee2a in the "Filter By" field and no logs are ever shown.
Logging is enabled globally and Logging Filters on ASDM is set to Debugging as well.
how I can get the RTLV working?

I have a 3560G that I cannot apply a policy route-map to one of the VLAN interfaces. I am running up to date software, c3560-ipservicesk9-mz.150-2.SE2 and it accepts the command, but does not show it in the sh run of the interface. I updated to this code as I had seen previously someone said it needed to be version 15 before you could apply route-maps to VLAN interfaces.

To configure a dynamic NAT, PAT, or identity NAT rule, I need to perform the following steps:
Step 1 From the Configuration > Firewall > NAT Rules pane, choose Add > Add Dynamic NAT Rule.
The Add Dynamic NAT Rule dialog box appears. However, when I click on Add I don't get the option to Add Dynamic Nat Rule. To see the options I get please see attachment.

I've run a across a strange issue that I've not encountered before and after the things I've tried am beginning to think it's a limitation of the router itself. What I have are 3 Cisco 1941 routers that are all endpoints for a customer's MPLS network. STL is the headquarters and both remote offices have a link back this router. Each of the remote locations only have 1 serial interface. It is a flat network with few routes and a small shoretel voip system running across it. Each router is running C1900 Software (C1900-UNIVERSALK9-M), Version 15.0(1)M5, RELEASE SOFTWARE (fc2).
QoS is configured as follows on each router:
class-map match-any AutoQoS-VoIP-Remark
match ip dscp ef
match ip dscp cs3
match ip dscp af31
class-map match-any AutoQoS-VoIP-Control-UnTrust
match access-group name AutoQoS-VoIP-Control
class-map match-any AutoQoS-VoIP-RTP-UnTrust
[code]....
If I try to apply the policy map to serial0/0/0, I get the following error:
% policy map utoQos-Policy-Untrust not configured
I've tried to create a different policy map with the same settings and get the same error. We thought that when it was first set up, each interface belonged to the same network, so we separated things out (hence the .252 mask). I'm not sure what else to try and I'm hoping its something painfully simple that I'm missing.

what is the purpose of the "Permint all traffic to less secure networks".
Well I know the purpose and the technique to handle some sercurity level is nice. when I cannot add add a rule without deleting this implicit rule?
The technique of security level is then obsolete?

I recently upgraded the ios image and the asdm on a cisco 5520 firewall. I use a policy on a cisco security manager to push policys out to this firewall. But it cant push to them now because the image has changed on the device.Is their anyway to re - assign the policy without having to do a new discovery.

I've been tracking a conversation on my firewall. I have an inside device that is trying to communicate to a server outside to send data. The conversation is suppose to be all 443. I see that there is a TCP connection made and a dynamic NAT that translates my inside device to the public IP, and appears to change the port to 65415. The problem I'm having is that the conversation ends with reset-O, and I'm wondering if that port has something to do with it, or if it's just that their server is resetting the connection because of an issue they are having? The vendor says no firewall rules are needed for this device to communicate with their server.

I need to allow traffic between webserver in dmz and mssql (Microsoft SQL Server 2008).MSSQL use dynamic port (now it is 63796) and this cannot be changed.
Basically, I can allow such traffic using next configuration:access-list dmz extended permit tcp host 1.2.3.4 host 5.6.7.8 eq 1433access-list dmz extended permit udp host 1.2.3.4 host 5.6.7.8 eq 1434 access-list dmz extended permit tcp host 1.2.3.4 host 5.6.7.8 eq 63796
But, I would like to add mssql inspection and I did the next:
class-map class_sqlnetmatch port tcp eq 1433policy-map global_policyclass inspection_default inspect dns preset_dns_map inspect ftp inspect h323 h225 inspect h323 ras inspect ip-options inspect netbios inspect rsh inspect rtsp inspect skinny inspect esmtp inspect sqlnet inspect sunrpc inspect tftp inspect sip inspect xdmcp class class_sqlnet inspect sqlnet service-policy global_policy global

I am facing problem with ACE configuration. I want to redirect 443 traffic to my Proxy Server. But I am not able to do this. I want to redirect only subnet 192.168.80.0/24..Then only it is working but I dont have to have this policy to be applied on all the users only one subnet I want to have under HTTPS policy.
how can I apply the policy only on specific subnet so that port 443 traffic can be redirect and rest of all subnets can go direclty to Internet.

I have one ASA 5510, a primary ISP (cable, the single public IP lives on the ASA), and a backup ISP (ADSL, separate router that hosts its single public IP). I use IP tracking to detect link down on the primary. When I pull the plug on the cable modem and go to "Route monitoring", I can see the ASA's default route is now the backup ISP default route.That conforms with [URL] Pings to 8.8.8.8 fail however, and when I do a packet trace the ASA complains about the dynamic nat rule that still points to the primary ISP's interface.Only when I change the existing dynamic NAT rule (on my inside interface) to use the backup ISP's pool (which is a single 192.168.x.y address) , does 8.8.8.8 reply to my pings. So it kinda works but it's not full auto . I can't add a second dynamic nat rule on the same inside interface, nor can I select 2 IP pools in a single dynamic nat rule.

ASA 5520 can handle 2 ISP? not to load balance or not standby/active but to use the 2 ISP at the same time and separately. for example, ISP_A who has 10m will be dedicated to the customer A/VLAN A, then ISP_B who has 4m will be for the rest of the customer's traffic. Can the ASA 5520 do traffic shaping or policy map just like in a normal router?

I am prepping new ASA 5525-X's for a client that has multiple S2S VPN's. On some of the VPN connections, I need to do a policy nat to translate some of their subnets to a single IP address before it goes over the S2S VPN. However, when I try to use a subnet, I keep getting the following error:
Subnet cannot be used as mapped source in dynamic nat policy.
This works fine on their old ASA's which are running 8.2 code. I figured out I can use a network range, but cannot go over 65535 (or whatever it is) addresses in that range. This is very annoying when they have multiple networks they want to allow over the S2S VPN. Is there anyway around this or am I stuck creating a network range for each subnet?

I will be implementing a new firewall (cisco asa 5515x) on my existing 3750x (server switches) and my 2960s (user switches). What should I need to apply on my firewall and swtiches to make the implementation successfull. I will put my 3750x as my DMZ and my 2960s as my inside. The 3750x have multiple subnet and also the 2960s.which features and technologies i need to know on those 3 products. my 3750x and 2960s don't have any ACL defined and most common features are vlan, switchport, trunking, spanning-tree, stacking, vtp.how my asa knows that my 3750x/2960s have multiple vlans. my current connection right now on 3750x and 2960s is just through 6 ports i assigned as one trunk, below is my config [code]
my 2960s vlans are almost the same with my 3750x except vlan 160, 170, 192. but of course when i put this in asa, i have to segragate vlan for 3750x (192, 100, 110,160, 170) and 2960s (130, 150). for my 2960s connection to the asa and since this will have big bandwidth, i will use 3 ports on my asa (and trunk it) connecting to my 2960s and i will use 2 ports on my asa (and trunk it) connecting to my 3750x. the one internet ports and my one management ports on my asa will stay like that.

I am a novice with networks but do have a fair understanding of networks. I have a small business network, utilizing a RVS4000 router (Firmware V2.0.27)I am attempting to set up firewall rules to block certain web sites at certain times.I have successfully set up rules using source and destination ranges, to deny service 24 hours a day everyday.
However and here is the problem when I attempt to edit any of the rules (I want to change the time to certain hours of the day) it allows me to edit the rule but when I attempt to save I get an error message up saying there are invalid characters and it will not save the changes?create the whole thing with the changes I want it works fine, is this a known bug?

I'm trying to troubleshoot an ASA5505.
The original goal was to block "Mumble/Murmur" (a voip app) traffic, which runs on TCP/UDP 64738, both inbound and outbound, except to a certain host (63.223.117.170).
However, when nothing I tried seemed to make a difference, just to troubleshoot, I decided to try blocking all inbound traffic. I first disconnected ethernet port 0/0 to ensure that it was cabled correctly and the outside interface went down when I did. That worked as expected, so I confirmed I had the right interface and it was cabled correctly.
I then applied a "any any deny ip" rule as the first element in the outside interface access_list, as you can see below. However, it appears to have had no real effect and the hit count is very low (it should be astronomical).

I have a server behind an rv042 that i would like to block access to on one port from outside in. I have configured the rule as follows:
priority = 1. policy name<name>. enable<checked>. action = deny. service <service to block>. source interface = wan1. sources = any. destination = <public ip address of server>. day <nothing>.
This does not block the intended port from outside. I also changed the destination to be the private ip address and i changed the source interface to LAN and to *. What is the correct syntax to do this?. Port forwarding is enabled. I noticed that there is one entry in the forwarding table for the public ip but it is going to a dead private ip address. Would this have an effect?

I am new to v5.3, and I am not good at VPN.I just have my consultant to configure this correctly just today. Currently, there is only one rule for the access policy (Single Result Selection). That rule is to use Active Directory as the source for the authentication. And by default will deny any other access which is not found in the rule.Now... I just got an order that I need to setup a new user who will need to access to our network by using Cisco IPSec VPN (the software one). But that user is not setup in our Active Directory, and we do not want him to access our domain anyway. He only needs to access non-domain resourse...such as airconditioning controller by IP. So I am thinking to setup his account by using "internal identtity". If I do this way, what do I need to do to setup another access policy? May you give me some steps with little more details? OR... if it is not the way I should do...what else can I do to achieve this goal? Also, he said he could provide his static IP trying to access from. I have a ASA 5520.

I'm trying to configure policing and/or shaping on a setup of 2 x ASA 5505 Sec Plus. The units are placed in office A and office B and each have a ISP connection to the internet and a leased line with a capacity of 4/4 Mbit/s for interoffice communication.
On each ASA there's four subnets. VLAN 200 is used to connect the offices through the leased line.
Subnets:
Outside = 2
Data = 10
Voice = 100
Linknet = 200
I've read a lot of articles and posts about shaping and policing on the ASA but still can't get it to work like I wan't to. I'm trying to limit all traffic besides IP-telephony traffic to 3 Mbit/s and thus reserving 900 Kbit/s for voice traffic. I tried setting a service-policy on the linknet interface on each ASA and set Traffic match to Any traffic and QoS settings for both input and output.
I can see traffic passing the policy when I run the "show service-policy police" command but it never seems to be high enough to be policed which is strange since the ASDM monitoring shows that I'm pushing 3900 kbit/s. I file transfers verifies that policing does'nt work.

I have pair of ASA 5550 and I am trying to copy a new config to my member1 (active) as the new configuration I want to use for the pair. I want to copy this to start-up config on member1 and then reload member1 and have it copy the same config to member2 (stdby). I guess I am trying to understand if I copy the configuration to member1 and reload it, member 2(stdby) will have become active and try to copy the old configuration to member1 which I do not want.
get the commands straight that I need to execute to make sure the new startup config gets to both members without being overwritten?
