Cisco Firewall :: ASA 5510 - Multiple Static Route Tracking
May 15, 2013
I am trying to set up my ASA5510 the fail over of ISP when it can't ping three different IP. I create three different tracking to three different IP using sla monitor & track rtr. But when I do
route isp2 0 0 yy.yy.yy.yy 50
route isp1 0 0 xx.xx.xx.xx 31 track 1
route isp1 0 0 xx.xx.xx.xx 32 track 2
route isp1 0 0 xx.xx.xx.xx 33 track 3
the last route will replace the previous two and only the last route command takes effect.Is there anyway I can set up the fail over to ISP2 only when it can't ping three different IP from ISP1?

I am trying to implement static route tracking on a Catalyst 3560G ( WS-C3560G-48PS, IOS version 12.2(35)SE5 and SW image C3560-IPBASE-M). The configuration is as follows:
track 101 rtr 1 reachability
!
rtr 1
type echo protocol ipIcmpEcho 10.199.101.2
rtr schedule 1 life forever start-time now
!
IP address 10.199.101.2 is reachable via ICMP (its the next-hop router).
The static routes configured are the following:
ip route 0.0.0.0 0.0.0.0 10.199.101.2 track 101
ip route 0.0.0.0 0.0.0.0 10.200.52.1 20
But only the secondary route(ip route 0.0.0.0 0.0.0.0 10.200.52.1 20) its being installed on the routing table by the switch.

Is it possible to assign a static route to an interface and not globally on a ASA 5510 ver 8.3.
I have two links between my offices one for Data via a VPN and one for video traffic which is a secure connection with QOS end to end.
All interfaces are on the same security level of 100 except Outside which is 0.
Office 1 Interfaces ASA 5510
VLAN 1 vOffice1Data 10.40.1.0/24
VLAN 3 vOffice1Video 10.40.2.0/24
VLAN 5 vInterOffice 10.40.5.0/24 (QOS connection Between Offices)
[Code]....
At the moment if I try and access data from VLAN 1 to VLAN 4 it gets to the destination ok going through the static route and over the vInterOffice connection but the problem is VLAN 4 returning the traffic. This fails because there is no static route back to VLAN 1. If I create a static route from Office 2 to VLAN 1 then it will route all my data traffic over it as well.

I am having touble with a NAT concept. What I have is a 3rd party software VPN product that basically tunnels encapsulated traffic to/from a server sitting inside the network. Right now this traffic utiluizes a physical interface on the ASA5510, but I need the interface for another project.
What I have is this:
Internet<----->ASA<-->router<-->4507(layer3)
| |
| |-Vlan1

I've enabled antispoof on all interfaces on asa 5510.If you start a traceroute to a network on the default route, everything works, since replies comes to an interface with route 0.0.0.0/0 defined.If you start a tracer route to a network that is NOT on the default route (let's assume coporate MPLS), you only get response from first carrier router, the other are discarded because of anti spoof violation.
I have ICMP inspection and icmp-error inspection enabled.

We use ASDM 6.2 to manage our Cisco ASA 5520 running ASA Software Version 8.2 (1). I just noticed that some static routes have "A-" when you view the static routes with ASDM e.g. A-172.24.0.0 or A-192.168.176.0 (pls see attached print screen). I haven't seen this before and dont know what it means.

I have inherited an ASA 5520. In doing some auditing of the setup, I have noticed a Static Route that has the inside interface of the ASA as the Gateway IP. I am trying to understand the purpose of this route or why a route would be setup this way.
Example Static Route:
Inside 10.xx.31.0 255.255.255.0 10.xx.xx.10 (10.xx.xx.10 is the inside interface of ASA)

I want to know with an ASA 5505 w/ Security Plus License I get up to 20 VLANS/Named Interfaces.I have a customer that is getting a new subnet of external IP addresses from their service provider and a different default gateway to accomodate re-hosting their datacenter at their main office instead of at a Colo. My question, when building out their new DMZ, can I have multiple route 0.0.0.0 commands?
Example.
Current Default Gateway 1.1.1.X
Internal hosts 192.168.1.0 use and are natted to 1.1.1.X
New Default Gateway for DMZ Servers 2.2.2.x
Internal hosts still use 1.1.1.X, but server hosts in 192.168.1.3 should use 2.2.2.X -- there are also a bunch of pre-existing static NAT rules for these servers such as 2.2.2.30 translates to 192.168.1.30.
I think I would accomplish this by using the following:
route inside 0.0.0.0 0.0.0.0 1.1.1.X
route DMZ 0.0.0.0 0.0.0.0 2.2.2.x
Would this be correct?

I am setting up a Cisco ASA 5505 first time for My organisation, I usually setup Cisco Router, I have 10 Static IP, & Have 6 Server (S-1, S-2, S-3, S-4, S-5, S-6), Traffic Should be pass through the ASA and is distributed to the destination server that is specified in the packet. LAN servers can be separated into discrete networks for security. For example, a private LAN for internal traffic accessed only via remote dial-in VPN sessions and Want to Configure DMZ for Server (S-4, S-5, S-6) that allows public web traffic.
I have Attached My Network Diagram I have some question,
1:- Can we Configure Multiple Static IP On ASA 5505 ?
2:- If Diagram is wrong what change need to be done ?

We have a need for an inside address to have more than one static NAT outside addresses. I know this wasn't possible before 8.3.X code. I still can't quite get it to work with 8.4.X code yet.
Here is what I had with 8.2 code.
static (inside,outside) 10.21.197.0 10.17.197.0 netmask 255.255.255.0
our inside network is 10.17.197.X/24. the current NAT we have in place is 10.21.197.X/24.
we need to add an additional NAT of 10.22.197.X/24 and I also have networks that will need to hit the address with no NAT.
I do know the source networks where I need each of the three cases:
from 172.20.X.X I need to hit the inside of 10.17.197.X natively, no NAT.
from 192.168.X.X i need to hit the inside of 10.17.197.X with 10.21.197.X NAT
from 10.10.X.X I need to hit the inside of 10.17.197.X with 10.22.197.X NAT

I need to replace an ASA with an IOS firewall router, and am not sure how to migrate the NAT configuration. Specifically, there is an interface "3rdparty" that has onward connectivity to other private addresses, so our internal addressing is hidden. For some reason there are static NAT rules in different directions across the interface, but at present I cannot see why. Thinking in router terms, all that springs to mind is the inside and outside tags for the interfaces, but also that it might need "overlapping" NAT to be configured.

We have a Nexus 7010 running version 6.1(2).
I'd like to use IP SLAs and object tracking to define static routes for specific source/destination traffic across some WAN links we have. I've done this in IOS and it's worked fantastically, but I've not found where/how to do this on the Nexus 7010 platform (or any Nexus platform) as of yet. I could have sworn that this was going to be introduced in the 6.x code? Below is an example of how we do this in the IOS world:
track 11 ip sla 1 reachability
delay down 15 up 15
ip sla 1
[Code]....
Esentially this gives us the option of using a "failover" default route. I've attached a basic diagram to explain what we are trying to do with IP SLAs and object checking. The tracking should be configured against an SLA that uses icmp and the static routes should be configured against the tracking.

I am at a loss on configuring a new ASA5505 for multiple static port translations.I would have expected to simply add several service command to a network object to complete the task, however, the service command overrides the previous and replaces rather than adds to the translations. [code] However, if entered in that order the 8443 overwrites the 8080 static translation.What is the correct procedure to establish multiple translations? If someone could also provide the "old" style for pre 8.2 release, I'd like to compare because I thought I used to do this with an access-list somewhere.

I have configured a remote access VPN on my Firewall ASA5510. Everything worked fine and I can successfully connect through the VPN. The problem is I cannot ping or connect to any of my internal network resources. I tried to add a new NAT route from outside to my internal servers using the defined pool but due to a new ASA version there are many changed I see in the NAT routes

We have a ASA 5505 and a 5510, that we are using site to site.I need to traceroute from the 5505-5510.. From the outside interfaces.. Don't want to do this through the site-to-site.I have temporarily added a few acl on the outside interfaces.when i traceroute it only goes one hop.. Maybe thats the way it suppose to be? I need to know all the hops between the outside interfaces on the 5505 to the outside interface on the 5510.

I need to create a firewalled segment that not only separates hosts from general population, but also from each other. The solitary confinement of firewalled segments.I know that I could create a bunch of sub-interfaces, one for each host or group that needs to be isolated, but I'd really rather not have to do that if possible. 1) It could become a management nightmare between ACLs and sub-interfaces and 2) it's a waste of IP addresses.s there any way that I can create a bunch of separate VLANs behind the firewall and have them all terminate at the firewall, using a single firewall IP address for the gateway?
VLAN 1 - hosts 1.1.1.5 and 1.1.1.6VLAN 2 - hosts 1.1.1.7
Firewall DMZ Interface - 1.1.1.1VLAN 3 - hosts 1.1.1.8 and 1.1.1.9
This way, the hosts are isolated and can't talk to each other unless they're on the same VLAN.I'm working with an ASA 5510 running 8.2.4(4).

In the restructuration of my company network we install due ASA 5510 in failover for the management of internal network and DMZ. We configure the ASA in routed mode, we create the sub interface for server, client and dmz subnet and we connect the firewall ti the network. Everything works very good except the intervlan routin. If i try to send or receive a file in every protocol, ftp, http, smb o if i try to conne with rdp or vns to an host in a different vlan the connection goes very very slow. I particular a ftp connection between two host goes ti 15kb/s. I check all cable and port for some error on duplex ro speed, end all the uplink are 1gb and the single client connection 100Mb. I know that the main purpose of the ASA is not doing routing stuff but this behavior is very strange.

I was configuring route tracking at a client with several sites to route across GRE tunnels and being able to detect a failure of the main site. To my surprise when configuring a 2800 series router (after sucessfully configuring a 1800 series on the same infrastructure), a 2821 with IOS 12.4(24)T2 IPbase, the commands for ip sla object tracking don't show up.The feature navigator says the router supports this, but it just won't take the commands (also tried older versions of the commands such as "ip sla monitor.." and "rtr .." to no avail).

I want to configure Reliable static routing with object tracking. I have a cisco 3825 and 3925 router in which the hsrp will be configured . Now these two routers are connected a remote site via three different WAN connectivity as under
1. MPLS
2. LL-1
3. LL-2
The priority of routing is also the same sequence.
Now if the MPLS goes down the remote site should be connected via LL-1. If both the MPLS and LL-1 goes down the remote site should be connected via LL-2.
The LL-1 is terminated on cisco 3825 and LL-2 is terminated on cisco 3925. MPLS is terminated on both cisco 3825 as well as 3925 router.
Whether multiple tracking options are available so that i can achieve the same. Topology diagram is attached.

One of our customers has asked us to Nat from the LAN to the Voice LAN based on destination IP address in order to access a public phone server through a vendor managed voice router..
Internet for everything else
|
|
Inside ------------------------> ASA 5510 -----------------> Voice router ------> outside to public phone server only
10.10.1.0/20 10.10.1.7/320 172.16.20.1/24
Voice------------------------->
172.16.20.0/24 172.16.20.254/24
Here the ASA5510 has an interface in both networks and the inside network can ping the voice network through the firewall by using non at acls. The phone server can only talk to the 172.16.20.0/24 network. So I need to nat the 10.10.1.0/20 network to the Voice interface on the ASA 172.16.20.254/24.
So I think I need the following static but I get the error below:
static (Inside,Voice) interface 10.10.0.0 net mask 255.255.240.0
WARNING: All traffic destined to the IP address of the Voice interface is being redirected.
WARNING: Users will not be able to access any service enabled on the Voice interface.

have a question. I have a ASA5510 with IOS version 8.2 . I have my firewall and behind it also have a mail server eg 192.168.1.x. When i send email from inside network it doesn't show as if it's coming grom the out side nated public IP of my server but IP of firewall. What am i missing my example nat statements are . Nat-control is disabled.
static (inside,outside) 196.68.99.x 192.168.1.x netmask 255.255.255.255

I have an issue, of two parts. The first part I believe I have figured out, just the second part I am unsure of. I have an ASA 5510, currently, there is a mailserver that is static NAT'ed to one of my ISP routed IPs (not the IP of my main Dynamic PAT/Outside interface). I need to convert this over to PAT for ports 25,80,443, etc (standard ports). I know I need to remove the static NAT statement and add in the PAT statements, but I need traffic from that machine to continue to go out the IP assigned to it by the static NAT.
E.G.
1.1.1.1 <- main public IP on outside interface, everything gets internet through this IP
1.1.1.2 <-> 10.10.10.10 static NAT to mailserver, secured with ACLs
I need to enable the mailserver to continue to appear to the world as living on 1.1.1.2, due to MX records and rDNS settings, etc...
The terminology for this setup escapes me at the moment.

I recently added a business cable modem to relieve some of the congestion I was getting on my T1 for our MPLS network. There was an ASA 5510 collecting dust in a closet here and I thought it would be the perfect device for firewalling the traffic coming in from the Cable modem, and handling the routing of our internal MPLS traffic as well. Internet setup was cake. The test laptop I have using the ASA as it's gateway has great internet service but it cannot ping across either of our MPLS networks. I have one MPLS with AT&T and one MPLS with EarthLink. My hope was to use the cable modem as the Default route for all unspecified internet traffic and route our internal MPLS traffic to the cisco 2800 routers that are currently in place for the MPLS. I can ping across the MPLS when I telnet to the ASA, but I cannot ping across the MPLS from the client that is connected to the ASA.
Here's the topology I'm working with

I've got an ASA 5510 that has been working like a charm for some time now. Until now we've not had to nat any resources to the outside. I created network objects for an internal host and an external host. The internal host has to respond to requests on tcp/2001.
The internal host has no problem accessing the internet, but when I attempt to access the internal host from the outside, I get the following:
4 Sep 20 2011 16:20:33 fw_outside_ip 62678 outside_host 2001 Deny tcp src outside:outside_host_ip/62678 dst inside_host:inside_host_ip/2001 by access-group "outside_access_in" [0x0, 0x0]
When I try to use the packet tracer to simulate the outside traffic, I get the following
5 Sep 20 2011 16:17:41 inside_host 2001 Asymmetric NAT rules matched for forward and reverse flows; Connection for tcp src outside:outside_host/1065 dst inside_int:inside_host/2001 denied due to NAT reverse path failure
I've got over my NAT statement and access rule and can't find anything wrong with either.
Here are the pertinent NAT and access rule...
static (inside_int,outside) tcp interface 2001 inside_host 2001 netmask 255.255.255.255
access-list outside_access_in extended permit tcp host outside_host host inside_host eq 2001

I got the charge of a ASA 5510 running with 8.3(1) version.Found that this is simple config with Patting for inside host and couple of Static Nat for web servers and FTP server as well.
There is lots of other configuration being done,I assume for the purpose of just R&D by the previous administrator.I need to understand if the following Nat statements holding any relevance?
Where we are running Only NETWORK_OBJ_192.168.0.0/23 subnet at inside and there is no other subnet defined in rest of the statements.i.e 10.0.0.0/27 and 192.168.1.128/27 doesn't exist at all.

This problem applies (in my case) to our ASA5510. The issue here is that the http service on the ASA is runnnig off of the standard port 80. Login to the firewall and run the following.no http server enable http server enable 8080,Now you should be able to add a NAT/PAT on port 443 to another server of your liking. Just remember when you attempt to use ASDM to manage the ASA in the future to specify the new port 8080.

I'm having a bit of trouble determining the best way to do this... I have 12 V LAN's set up (sub interfaces on a redundant group of two NICs) on my ASA 5510. On several of these, I want them to be able to access the internet but not access other V LAN's.
By default, they have a rule like "any to any less secure", and since the outside interface has a lower security level, this works great. But if I create an ACL on the interface, this rule disappears. I can restore internet access by adding an "any to any" or "(this interface's sub net) to any" rule, but this seems to imply that it allows access to any v LAN. Do I have to create a set of "deny" rules for each V LAN, on each V LAN, followed by an any-any rule to allow internet access, or is there a cleaner approach?

How can i achieve high availability for this scneario?is this possible to implement some HighAvailability and to offer the actual services to each of them, in case that the other firewall fail?What about using subintefaces? can i connect bothe ISP and Customers links on one or each of them, in case that firewall01 fails, all the services to be online on firewall02?

I have an ASA 5510 running version 7.0. I have a problem with an exchange server using a static map and its outbounc connectivity. It connects outbound through the global address even though inbound connectivity works fine through the static mapping. The recent changes are changing of the zero route through a different interface (there are to circuit connected to this ASA on different interfaces). So the idea was to get all workstations in the office using the global address and routing out through one circuit, and the servers connecting in/out through the other circuit. Shouldn't a static mapping ignore what the zero route is?
Here are what I believe to be the relevant configs.
interface Ethernet0/0
description New 6mb circuit
speed 100
[Code]....
So exchang2 server can be connected to from the outside properly via IP xxx.207.51.231/exchange2-outside, but all outbound connections from this server are going out via IP xxx.122.47.218/circuit-6mb as do all the workstations due to the global address statement.
