Cisco Firewall :: Using Static Policy NAT On ASA 8.2?

Jul 6, 2011

i am doind a policy NAT on the folowing scenarion. 
 
acess-list policy_nat extended permit ip host 10.0.0.1 host 192.168.1.1
static (inside,outempresa) 170.66.53.1  access-list policy_nat
 
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 ?

Cisco VPN :: Convert Static Policy NAT From 8.2 To 8.6?

May 26, 2013

I have a L2L tunnel I need to convert from 8.2 to 8.6  and need to understand the static policy Nat conversion.  I have single hosts that require a 1-1 nat to addresses given to be my the vendor that reside on my firewall.  Other works  i have /24s that I static nat my inside host to so that the vendor can access the host for support.Example. server 10.11.103.44(real server on my inside network)
 
5.5.98.0/24-Defined for local traffic via L2Ltunnel
 object-group network Carebridge_Local
description Mckesson Local network list
network-object 5.5.98.0 255.255.255.0

How would I accomplish the same in Ver. 8.6

Cisco WAN :: 2811 - Static Routes Need Some Input Policy Based Routing

Aug 13, 2011

I have 2 connections a single T1 for voip traffic only and a DSL line for data traffic.the dsl was migrated to a 2811 with out any issues now comes the time to move the T1 over.
 
on the T1 side I am able to ping the WAN router and the LAN router IP address but nothing behind it.

currently this is the only statment on the router:
ip route 0.0.0.0 0.0.0.0 Dialer1
 
as a quick a dirty to remove the above i tried:
no ip route 0.0.0.0 0.0.0.0 Dialer1
ip route 66.55.110.0 255.255.255.0 Dialer1
 
but the DSL side dropped. we have a 66.55.110.152/29
 
for the T1 i would use the following statement.. we have a 209.98.53.192/27
 
ip route 209.98.53.0 255.255.255.255 65.32.70.177

Cisco Firewall :: 1811 / Zone-Based Policy Firewall Configuration

May 16, 2011

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
!

Cisco Firewall :: ASA 8.3 Dynamic Policy NAT

Apr 11, 2011

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

Cisco Firewall :: Default FWSM 4.1 Inspection Policy

Jan 10, 2011

On FWSM (running version 4.1 in my case) the default global policy uses the following class map:class-map inspection_default match default-inspection-traffic
 
What "default-inspection-traffic" includes? Is it all traffic? If so, do I really want all my traffic to go through the inspection engine? I would imagine this would have a performance impact on traffic that is not part of the protocols being inspected.

Cisco Firewall :: 5500 ASA Modular Policy Framework

Aug 14, 2011

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.

Cisco Firewall :: Asa 5510 Error - Cannot Add Policy To Rule Engine

Mar 5, 2013

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?

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.

Cisco Firewall :: Policy Based Routing To ASA5550 Inside Interface?

Mar 4, 2011

Is it possible to establish PBR rules that set the ip next-hop to point directly to the inside interface of the ASA5550?Or, do I need to direct this PBR traffic first to a directly connected router interface and then default route to the ASA?At a high level, here's what we have:
 
ISP 1 - with /21 IP PrefixNo BGP Routing3845 Edge Router - Default Route to ISP 1PIX535 Firewalls (HA) - Default Route to Edge RouterLAN Core/Distribution - Default Route to PIX535 Inside InterfaceAll applications/services use this egress path for PAT/NAT/DMZ/VPN/Etc. 

Here's what we are adding:
 
ISP 2 - with /24 IP PrefixNo BGP Routing3925E Edge Router - Default Route to ISP 2ASA5550 Firewalls (HA) - Default Route to Edge RouterSame connectivity to LAN Core/Distribution 

Goals:Maintain ISP 1 for nowMigrate only end user Internet traffic to ISP 2No disruptions to applications/services using current DefGW to PIX535 

Question: how to best use PBR to selectively direct traffic to the ASA inside interface?

Cisco Firewall :: ASA5510 Delete Default Service Policy Rules?

We have a problem with some websites being blocked every now and then. Everyone inside can access this external website for weeks, and then suddenly it's not available for a few hours, and then it comes back. All without me making any changes to the firewall, ASA5510. The external website that has nothing to do with us can be accessed from anywhere outside our network, example on my iphone through Verizon.
 
We have not set up any rules about blocking websites, all I found was the Default Service Policy. After backing up and then deleting the rule we are able to access all sites.

Cisco Firewall :: ASA 5510 / Blocking / Shunning Hosts With Service Policy Rules?

Dec 20, 2012

I have an ASA 5510 deployed and we are getting a tonne of port scanning traffic (who isn't these days) and ping traffic.The threat scanning thresholds seem a bit too high and was wondering if there is a way to use a Service Policy Rule to perform a Shun/Block of the hosts rather than the firewall simply blocking the request via the ACL and sending a reply.
 
In other words, if I do nothing, I know the ACL is protecting the resources but it is still replying to the client connection. I want the end result to be the same as a "Shun" where the connection is dropped and no reply is sent. how to employ Service Policy Rules to thwart Port Scanning and/or IP Spoofing?

Cisco Routers :: SR520 Not Criterion In Zone-based Policy Firewall Class-maps

Jan 16, 2012

I'm trying to configure a zone-based firewall on an SR520 and am confused about the 'not' criterion. The 'zone-design-guide' says (my stress): Class- maps define the traffic that the firewall selects for policy application. Layer 4 class-maps sort the traffic based on these criteria listed here. These criteria are specified using the match.where my intention is to let only LAN hosts with IPs in the range 192.168.1.1 to 192.168.1.7 out through the firewall. There may be an easier way of doing this which I'd be pleased to hear about. But, even if there is, I'd also be interested to know what I'm doing wrong in the above.

Cisco Firewall :: 2911 - Control Link In Zone-Based Policy High Availability

Jun 26, 2012

I have set up a zone-based policy firewall with HA on two 2911 routers as per the Cisco security configuration guide, for an active/passive LAN-LAN cluster. All works as expected, but there is one problem I find: when the control link between the two devices fails, they go into an active/active state as each member assumes it's the last surviving member. The ARP entries for the Virtual IPs on the neighboring devices point to the device that last claimed the active role (usually the standby device). This works in a way, just sessions don't get synched anymore (control link is the same as data link). Now when the link comes back up, the preemtion works and the active, former standby device goes back to standby. But the ARP entries on the neighboring devices still point to the standby device and nothing goes (also sessions established during the active/active state are lost due to resync with the now active member).
 
This is a single point of failure and what I need is a way to mitigate that. Under:

redundancy
application redundancy
group 1
control <interface> protocol 1

only one control interface is allowed. Other manufacturers with similar functionality provide for the possibilty of a backup control link, for example the internal LAN interface or a dedicated backup link.
 
How would I go about that? Maybe use a port-channel for the control/data link (but I'm out of interfaces)?
