Static NAT Question - Public to Inside ASA 9.1x

Hi All.. I'm having hard time wrapping my head around the post 8.2 nat statements, please help.
I have a DMZ server that has a list of ports that need to be accessible from the outside from specific IP addresses (this is a video streaming relay server). It also need to be able to push the stream to a specific IP address as well. I can do identity nat, and it'll go out and I see it's using IP, but obviously traffic doesn't get in... I can use sample web server nat's I've found and it works for the web management port, 8088, but I can't figure out how to map multiple ports to it:
Remote Public IP's: 77.88.99.11
Local Public IP: 12.12.12.1
Ports required:
object-group service srvgp-stream-remote
service-object tcp destination eq www
service-object tcp destination eq https
service-object tcp destionation eq 8088
service-object tcp destination eq 1935
service-object udp destination range 6970 9999
service-object udp destination range 30000 65000
service-object udp destination eq 554
I can get this to work:
object network server-external-ip
host 12.12.12.1
object network webserver
host 192.168.1.100
nat (dmz,outside) static server-external-ip service tcp 8088 8088
access-list acl-outside extended permit tcp host 77.88.99.11 object AngelEye eq 8088
But again, I have no idea how I would do such a thing with a list of required ports? I don't see that's an option in the syntax. Additionally, would this provide an 'identity nat' in case the server had to send info out to the public ip via these same ports or do you require a seperate identity nat to do this to the same public ip addresses?
Any help is greatly appreciated.

With that many ports, you should use the public IP exclusively for the Webserver:
object network webserver
host 192.168.1.100
nat (dmz,outside) static server-external-ip
If it's not possible to use that IP only for that server, you can configure manual-nat for these ports:
nat (dmz,outside) source static webserver server-external-ip service srvgp-stream-remote srvgp-stream-remote

8.2 to 8.3 static nat question

So, in 8.2 If I had an inside interface at 10.10.10.1 and an mpls interface (sec-100) at 10.20.20.1, and I wanted traffic to traverse between the two to interfaces, I could write the following statement:
static (inside,mpls) 10.10.10.0 10.10.10.0 netmask 255.255.255.0
What would this look like in 8.3?
Thanks!

Hi,
In the 8.3+ software levels you dont need any NAT configuration between 2 interfaces if you dont need to specifically NAT something.
If you have a Dynamic PAT configuration from "inside" to "mpls" that contains the networks behind "inside" as the source address then in this situation you would need another NAT configuration to enable communication from the "mpls" to "inside". (to enable bidirectional connection forming that is)
If there is no NAT configuration between "inside" and "mpls" at the moment then you wont need any NAT configuration. You will just have to make sure the traffic is allowed in the interface ACL. If your have equal "security-level" between the interfaces then you will have to make sure you have "same-security-traffic permit inter-interface" also configured

What is the maximun number of static NAT in ASA

Hello everybody,
someone know how many sessions of static nat can configure in cisco ASA ???
thank you for you response...

Hi,
That question really depends....The answer is very simple thou, the amount of xlates is not limited. What really limits yourself is either PAT (Which allows 64000 xlates for each IP you use to do PAT) or the amount of connections.
As far as Static NATs go, there is no limit. You can create as much as you want, but eventually doing a sum of all the resources (inspections, ACLs, QoS etc) will increase the use of the memory.
So, bottom line, you will not get an error that says, static NAT cannot be created.... you will get eventually an error related to memory.

L2TP over IPSEC Static NAT trouble

I have a 5510 that i have configured for L2TP over IPSEC, not using AnyConnect. As of right now i have two open issues that i cannot figure out. The first, and most prevelant being, VPN clients are unable to ping/access any of the hosts that are assigned a static NAT from the inside interface to the outside interface. I was able to circumvent this by adding another static NAT to the public interface for the incoming clients, but this caused intermittent connectivity issues with inside hosts.
The second issue involves DNS. I have configured two DNS servers, both of which reside on the internal network and are in the split_tunnel ACL for VPN clients, but no clients are using this DNS. What is the workaround for using split tunneling AND internal DNS servers, if any?
I'm looking for any help someone might be able to give as i've had two different CCNA's look at this numerous times to no avail. The config is below.
To sum up, and put this in perspective i need to be able to do the following...
VPN CLIENT (10.1.50.x) -> splitTunnel -> int G0/2 (COMCAST_PUBLIC) -> int G0/3(outside)(10.1.4.x) -> STATIC NAT from G0/0(inside)(10.103.x.x) -> NAT (10.1.4.x)
A ping from a VPN client to any internal host works fine, unless it is one that is NAT'd. You can see in the config where i added the extra STATIC NAT to try and fix the issue. And this works perfectly across the tunnel but only intermittenly from the internal 10.1.4.x network.
As well as any help with DNS. Please advise, thank you.

No one? I'd be happy to provide any more info if someone needs it, i'm just looking for some sort of direction. I did almost this whole config by myself and i'm completely self-taught Cisco, so weird things like this really through me.
Please help. Thank you

ASA 5510 Multiple Public IP - Static NAT Issue - Dynamic PAT - SMTP

Running into a little bit of a roadblock and hoping someone can help me figure out what the issue is. My guess right now is that it has something to do with dynamic PAT.
Essentially, I have a block of 5 static public IP's. I have 1 assigned to the interface and am using another for email/webmail. I have no problems accessing the internet, receving emails, etc... The issue is that the static NAT public IP for email is using the outside IP instead of the one assigned through the static NAT. I would really appreciate if anyone could help shed some light as to why this is happening for me. I always thought a static nat should take precidence in the order of things.
Recap:
IP 1 -- 10.10.10.78 is assigned to outside interface. Dynamic PAT for all network objects to use this address when going out.
IP 2 -- 10.10.10.74 is assgned through static nat to email server. Email server should respond to and send out using this IP address.
Email server gets traffic from 10.10.10.74 like it is supposed to, but when sending out shows as 10.10.10.78 instead of 10.10.10.74.
Thanks in advance for anyone that reads this and can lend a hand.

The flows from email server ( 192.168.2.7 ) , will be NATed to 10.10.10.74, only if the source port is TCP/25. Any other souce port will use the interface IP for NAT.
Are you saying that this is not happening ?

Static nat & public IP on inside interface.

Hello Guys,
I am facing some issue related to static nat please provide your replies. let me explain the scenario.
At site we have 4 cameras connected on switch and NVR (network video recorder) also connected on the same switch.
Locally at site we are able to access the four cameras via http/web and also through NVR software .
In order to access this cameras from remote location, we did static natting in router with pubic ip address for this cameras private IP address. Find nat table below.
At remote site/from internet when we are adding the cameras in NVR software using public IP address. Later automatically public IP address resolving into private IP address.
We are able to access cameras individually using http://<public ip address for camera> but when we try to add it in INVR software its changing public ip address to private.
Camera Name
Private IP address
Public IP address
Camera 1
192.168.1.3
xx. x8.23.115
Camera 2
192.168.1.4
xx.x8.23.116
Camera 3
192.168.1.5
xx.x8.23.117
Camera 4
192.168.1.6
xx.x8.23.118
Below is the configuration for the router. I am concerned about the public IP address which is assigned on internal/LAN interface instead of outisde interface by ISP. In other project i experienced Public IP address is at outside interface and private is at inside interface and we do static nat for inside to outside interface.
But here when i access the cameras through public IP individually its working but not when i am adding this public IP in NVR software. May be something is wrong with static.

Please advise on the above configuration. Your help in the above regard will be highly appreciated.
Many Thanks in Advance.

It is a bit odd to see the IPv4 address assigned this way. (Putting it on a Loopback would be a more elegant approach if the ISP is using private addresses for the WAN link.) But, there's nothing in here that would cause the NAT to fail. I suspect that the cameras are doing an HTTP redirect to their private IPv4 addresses at some point and this is causing your software to switch.
With this configuration, there's no reason why you can't just put the cameras directly on the public addresses and forego the NAT entirely. If there is a redirect going on, they will redirect to the correct IPv4 address and things will still work.

Public Pool, 2 ASAs, Static NAT ...

I am looking for help on a mixture of Routing and Switching and Firewalling ...
So I have a router connected to the ISP ... the router is also connected to a switch. Into that switch I have pugged two ASAs. A 5505 and 5520.
I was given a /27 (255.255.255.224), 30 address block from the ISP. Let's say the last octet of the router is .1, the ASA#1 is .2, and ASA #2 is .3.
Now I wan't to use the rest of the addresses for Static NAT (the IP addresses are publically registered to their own domain names).
Can I use any of the rest of the addresses .4 through .30, on either ASA in Static NAT (1 to 1 translation)? Possibly even move them back and forth between ASAs?
How does the router know which as ASA it needs to forward the packet to if it is destined for .12 for example? Does the ASA send out an ARP message for each of its static addresses that it is using? They packets aren't broadcast to the subnet, are they?
Or is this a Layer 3 problem. Do I have to segment my /27 into two /28's on my router (requiring an additional interface and use of another IP address)?
I was trying to debate if I could possibly model this in GNS3.
PS the reason for doing this is for dissaster recovery, moving servers between racks without changing IP address scheme (the private addressing scheme behind each ASA is identical), etc.
Thanks so much for the help,

Can I use any of the rest of the addresses .4 through .30, on either ASA in Static NAT (1 to 1 translation)? Possibly even move them back and forth between ASAs?
--> YES you can
How does the router know which as ASA it needs to forward the packet to if it is destined for .12 for example? Does the ASA send out an ARP message for each of its static addresses that it is using? They packets aren't broadcast to the subnet, are they?
--> YES, the ASA will send out an ARP to tell the router that it has that particular static address
Or is this a Layer 3 problem. Do I have to segment my /27 into two /28's on my router (requiring an additional interface and use of another IP address)?
--> NO, you don't have to segment the /27 into /28

Static NAT to IP that is not local to ASA?

All, I have a doubt about a configuration I am requesting. I know just a little about ASA myself, but am working with a contractor on this project and he is not sure this can be done or not.
My applciation is this:
- ASA with internet and some public IP.
- Exisiting internal LAN of 10.10.10.0/24.
- New voice VLAN 10.10.100.0 on L3 SGE switch doing inter-vlan route between 10.10.100.0/24 and 10.10.10.0/24 via 10.10.10.1 (ASA internal interface)
- ASA will have static route to 10.10.100.0/24 via 10.10.10.254 (data VLAN interface on my L3 switch) This much is a known working configuration for me to allow voice and data vlans to route and require very little of firewall contractor.
Now I need static NAT of a public IP to my IP PBX on 10.10.100.1. The doubt I have is if they try to configure this the ASA will not want to make a NAT to 10.10.100.1 because that network does not exist anywhere in the ASA config.
Is there a way to make this work or will it be required/better to use an extra interface no the ASA and make it 10.10.100.0/24 and have the ASA do inter-vlan routing instead of the switch?
Thanks in advance,
Brandon

The inside static route is now working, thank you. Back to my original question about static NAT. I just need a public IP to pass all traffic to an internal IP that is on the 10.10.100.0/24 network not directly conencted to the ASA. I am thinking this would be the command:
static (outside,inside) 10.10.100.1 222.222.222.222 netmask 255.255.255.255
Does that seem correct and can you provide an example of what the ACL would look like? I want to just allow all traffic now for the purpose of remote IP phones and some admin and mobile apps using various ports. Once it is tested working I will let the firewall vendor layer security on.
Thanks again,
Brandon

MS NLB with ASA and Static NAT from PUP to NLB IP

Hi all,
I am trying to get MS NLB up and running. It is almost all working. Below is my physical setup.
ASA 5510 > Cat 3750X >2x ESXi 5.1 Hosts > vSwitch > Windows 2012 NLB Guest VMs.
I have two VMs runing on two different ESXi hosts. They have two vNICs. One for managment and one for inside puplic subnet. The inside puplic subnet NICs are in the NLB cluster. The inside public subnet is NATed on the ASA to a outide public IP.
192.168.0.50 is the 1st VM
192.168.0.51 is the 2nd VM
192.168.0.52 is the cluster IP for heartbeat
192.168.0.53 is the cluster IP for NLB traffic.
0100.5e7f.0035 is the cluster MAC.
The NLB cluster is using MULTICAST
I have read the doumentation for both the ASA and CAT switch for adding a static ARP using the NLB IP and NLB MAC.
For the ASA I found
http://www.cisco.com/en/US/docs/security/asa/asa84/asdm64/configuration_guide/mode_fw.html#wp1226249
ASDM
Configuration > Device Management > Advanced > ARP > ARP Static Table
I was able to add my stic ARP just fine.
However, the next step was to enable ARP inspection.
Configuration > Device Management > Advanced > ARP > ARP Inspection
My ASDM does not list ARP Inspection, only has the ARP Static Table area. Not sure about this.
For the CAT Switch I found
http://www.cisco.com/en/US/products/hw/switches/ps708/products_configuration_example09186a0080a07203.shtml
I added the both the ARP and Static MAC. For the static MAC I used the VLAN ID of the inside public subnet and the interfaces connected to both ESXi hosts.
On the ASA I added a static NAT for my outside Public IP to my inside pupblic NLB IP and vise versa. I then added a DNS entry for our domain to point to the outside public IP. I also added it to the public servers section allowing all IP traffic testing puproses.
At any rate the MS NLB is working ok. I can ping both the Public IP and the Inside NLB IP just fine from the outside. (I can ping the inside NLB IP becuase I'm on a VPN with access to my inside subnets) The problem is when I go to access a webpade from my NLB servers using the DNS or the Public IP I get a "This Page Can't Be Displyed" messgae. Now while on the VPN if I use the same URL but insied use the NLB IP and not the Public IP it works fine.
So I think there is soemthing wrong with the NATing of the Public to NLB IP even tho I can ping it fine. Below is my ASA Config. I have bolded the parts of Interest.
Result of the command: "show run"

Any help would be great! I think the issue is in teh NAT as I am able to access NLB IP from the outside and could not do that before adding the Static ARP stuff.
Thanks,
Chris

Also If I change to NAT from the public IP to the NLB IP to use either one of the phsyical IPs of the NLB cluster (192.168.0.50 or 51) it works fine when using the public IP. So it's definatly an issue when NATing the VIP of NLB cluster.

Dynamic PAT and Static NAT issue ASA 5515

Hi All,
Recently we migrated our network to ASA 5515, since we had configured nat pool overload on our existing router the users are able to translated their ip's outside. Right now my issue was when I use the existing NAT configured to our router into firewall, it seems that the translation was not successful actually I used Dynamic NAT. When I use the Dynamic PAT(Hide) all users are able to translated to the said public IP's. I know that PAT is Port address translation but when I use static nat for specific server. The Static NAT was not able to translated. Can anyone explain if there's any conflict whit PAT to Static NAT? I appriciate their response. Thanks!

Hi,
I would have to guess that you Dynamic PAT was perhaps configured as a Section 1 rule and Static NAT configured as Section 2 rule which would mean that the Dynamic PAT rule would always override the Static NAT for the said host.
The very basic configured for Static NAT and Default PAT I would do in the following way
object network STATIC
host
nat (inside,outside) static dns
object-group network DEFAULT-PAT-SOURCE
network-object
nat (inside,outside) after-auto source dynamic DEFAULT-PAT-SOURCE interface
The Static NAT would be configured as Network Object NAT (Section 2) and the Default PAT would be configured with Twice NAT / Manual NAT (after-auto specifies it as Section 3 rule)
This might sound confusing. Though it would be easier to say what the problem is if we saw the actual NAT configuration. Though I gave the reason that I think is probably one of the most likely reasons if there is some conflict with the 2 NAT rules
You can also check out a NAT document I made regarding the new NAT configuration format and its operation.

Static NAT Pre 8.3 ASA no untranlate hits

Hello all---
Having an issue w a pre 8.3 ASA static NAT.   The intention is to static nat an antivirus server hanging off our DMZ interface on the ASA- that address being 192.168.255.2….. to one of our public IP address (for the sake of this forum) 44.44.44.44. The ASA DMZ interface is 192.168.255.1.
I’ve configured the static NAT rule and the access ACLs on both the outside interface and dmz interface. For the sake of testing, I used just IP as the service –will restrict it later w the correct service ports once I know it’s working- and for now just have a windows laptop acting as the server for testing.
What I’m seeing is incrementing translate hits, but no untranslated hits at all when performing the command:   show nat dmz outside 192.168.255.2 255.255.255.255
match ip dmz host 192.168.255.2 outside any
    static translation to 44.44.44.44
    translate_hits = 549, untranslate_hits = 0
match ip dmz any outside any
    no translation group, implicit deny
    policy_hits = 170905
Also, I see no hits at all on the acl for the outside interface when trying to do a ping or telnet to ports running on the laptop\server.
So, it’s obviously translating out- to the public, but not from the public in to the private. Almost like it’s not reaching that public IP. We have other publics we translate to for other services…..with no issue
Here’s the pertinent lines – pretty simple at this point.
Outside Interface ACL
access-list acl_out line 48 extended permit ip any host 44.44.44.44
DMZ interface ACL
access-list dmz_access_in line 3 extended permit ip any any
NAT Statement on DMZ interface
static (dmz,outside) 44.44.44.44 192.168.255.2 netmask 255.255.255.255
Any help or clarification is appreciated……   thanks   Dennis…

Try seeing what the ASA is doing with the return traffic using packet tracer utility as follows:
packet-tracer input outside tcp 8.8.8.8 1025 44.44.44.44 23
...substituting the actual public NAT address for the 44.44.44.44 of course. (If you were using 8.3+ you would specify the real end host IP address.)
Here's a link to the command reference for more details.

ASA 8.2 Global Outside works, but static NAT mappings fail

Hello,
I'm usually not stumped by issues, but this one I cannot seem to figure out.
I have an older Pix and I've mirrored the config on a new ASA with 8.2(5) OS. It's a pretty basic config with one ACL for a few inbound port forwards to servers. The service is Verizon Fios Business.
When we switch over from the old Pix to the new ASA connectivity through global outside statment work fine. Workstations on the LAN can connect outbound to websites, etc.
However, none of the servers using static NAT mappings work inbound or outbound. And there are 4 servers, and we've tested them all for various issues. The static mappings are done using the static statement as such "static (inside,outside) exchange 10.0.2.7 netmask 255.255.255.255" and not using a network object. I have other installs with this same exact OS version that work fine with the static statement, so I'm not sure that this has anything to do with it. I'll add that these 4 servers also have inbound ports forwarded via one ACL, which also do NOT work.
When we switch it back to the Pix unit with same config, all the servers on static NAT work just fine immediately.
Can anyone give any insite on what the problem might be based on what I've described? I've checked and checked the configs and see no issues. And I've done may ASA configuration/installs, but I would say I'm moderately new to 8.x(x), although as I said above I have others in production working fine with static NAT mappings.
Thanks for any assistance,
Max

another thing you can do in addition to the packet capture mentioned by Harvey is a packet-tracer which will simulate a packet going through the ASA and could point us in the right direction of where the issue is.
packet-tracer input <interface name> tcp <source IP> <source port> <destination IP> <destination port> detail
I suggest running the packet tracer in both directions (from the servers to the internet, as well as from the internet to the servers). Keep in mind that when using the packet tracer with a source out on the internet you need to specify the destination as the NATed IP of the servers. The following link can give you a little more info on the packet tracer

One-to-many static NAT asa pre 8.3

Hi,
is one-to-many static NAT possible on asa version 8.2 ?

.. do you know if there are firewalls that can implement one-to-many nat ? tipically one private ip statically natted to many public ip .. checkpoint, fortigate ..

Static translation from dmz to inside on Asa 8.6

Recently upgraded to an Asa 5512x from a pix 515e. I have an Ipswitch secure MoveIT server on the dmz1 interface that needs to be accessed from both the inside and outside interfaces. I have setup a static nat from the outside to the dmz1 and it works, I can also connect from the inside interface. Now I need the MoveIT server to access the DNS server and email server on the inside interface so it can send notifications. On the pix I just created a static from the inside to the dmz1 using its own IP address - static (inside,dmz1) 192.168.1.7 192.168.1.7 net mask 255.255.255.255. I would then add the access-list to allow. How would I set this up with the Asa 8.6 commands?

Hi,
The default operation of the new ASAs/Softwares is that you dont configure NAT if you dont need one.
So if you for example have the following interfaces
outside
lan1
lan2
dmz
If you want the lan1, lan2 and dmz to communicate between eachother with the actual IP addresses, you dont configure any type of NAT between them (even the ones that you used to do with the old software with the "static" commands)
Only situations where I have configured Twice NAT is when I have configured a L2L VPN or there is migrated some old 8.2 or below software Policy NAT.
So to my understanding you would probably have a new type of Static NAT for the dmz1 server towards outside
object network DMZ-STATIC
host 192.168.1.7
nat (dmz1,outside) static x.x.x.x dns
For the same server to communicate with other networks behind the firewall (LAN networks) you shouldnt really need any addiotional NAT configurations. Only have the access-rules permit the traffic if it already doesnt do so.
You can always post some configurations if you want someone to take a look through them.

ASA 8.2 - Static NAT and Dynamic NAT Policy together

Hello community,
I have the following problem using a ASA with version 8.2.
1) I have this segment on interface Ethernet 0/0: 192.168.1.0/24
2) Through interface Ethernet 0/1 I will reach several servers using the same source IP, but other servers must be reached using only one IP, for example 192.168.1.70
so, I have configured a Static NAT Rule from interface Ethernet0/0 to interface Ethernet 0/1 which NAT the source IPs to the same IPs: 192.168.1.0/24->192.168.1.0/24. Also I have configured a Dynamic NAT Policy that states when destination IP is "server list" then all the source IPs must be translated to 192.168.1.70.
PROBLEM: when testing it...always the static wins....and Dynamic is never analyzed...Also, no priority for the NAT policy and NAT rules can be done on ASDM...what can I do? is there a way to do this on ASDM or CLI? (preferrely at ASDM)
Thanks for your reply and help!
