issue of nat sr520
Hi, I have configured the sr520 using the cca.
Basically I have a device connected to the sr 520 wireless with the IP 192.168.200.160.
The SR connects to internet via adsl and pppoe.
I have configured NAT to the unit for a number of ports, but it does not work.
I enclose an excerpt from the configuration, all the ideas I have a hurt

Issue of NAT...
Hi Experts,
Quick question, if I want to do NAT exception for ALL ip traffic on an interface in version 8.4 (2). What should I do?
I just want to check it again... would it work or do I have to use another method: nat (interface, all) static source a whole
Thank you
Soroush.
Hello
I guess you already asked something like that on the previous thread.
If you situation is still for no. HOSTS must be translated through the firewall then you can simply configurations to LET OUT all THE NAT.
Usually when people need hosts exempted from NAT they don't usually have some networks of destination for which it should apply. (VPN connections). If you set parameters of destination for the NAT configuration also.
You might naturally public subnets behind the firewall without NAT. As long as no other NAT rule fits these public subnets as a source, you can simply leave out all the NAT configuration.
What I tested I would probably the NAT configuration above although I mentioned in the other thread. It might even cause problems.
I suggest the other format which is basically that you describe networks source behind this interface under a "object-group network" and then configure the NAT rule
object-group network NETWORKS
network-object
network-object
NAT (interface, no) static source of NETWORKS
Pretty hard to say more than once is not an accurate picture of the situation.

Issue of NAT for ASA running 8.4 (5)
We have a client who is about to hang an ASA off the coast of the demilitarized zone of our firewall that is running 8.4 (5). This firewall is currently on another part of our network, and NAT will be considerably changed. Now, everything on the client firewall must be coordinated outside for the same thing as the IP model internal, for example like the old "static (inside, outside) 172.16.16.0 172.16.16.0 netm 255.255.255.0" command.
When I look at the document from Cisco for (conversion) NAT
( http://www.cisco.com/en/US/docs/security/asa/asa83/upgrading/migrating.html#wp96828), I see not all conversions between the two. This is not a "nat 0" because users need access to certain hosts inside the firewall of our customers.
Can someone tell me please in the right direction? Thank you
Hello
Lets assume that the following is true
- The new ASA has 'inside' and 'outside' network/interface only
- The ASA News should do EVERYTHING NAT 'inside' to 'outside' to any kind of situation traffic (your firewall handles this?)
Then you can simply have the ASA with absolutely no. NAT configurations. The ASA with new software releases 8.3 and above all automatically passes all traffic through the ASA UNNATED. We use it on a single client and it works very well.
Please let me know if the above is the case, or can't think of anything else

If I have a LAN or 10.1.1.0/24 and I want NAT all of the hosts in 192.168.1.0/24. I really don't want to create the object for each unique host network, because it's just for a lot. I just wanted to confirm by creating two objects then natting them must configure a NAT right one?
network object obj - 10.1.1.0
10.1.1.0 subnet 255.255.255.0
!
network object obj - 192.168.1.0
subnet 192.168.1.0 255.255.255.0
!
NAT (inside, outside) source static obj - 10.1.1.0 obj - 192.168.1.0 statick "remotely" destination "at a distance".
Now when the remote network need access to network 10.1.1.0/24 hosts they should just be able to access to?
10.1.1.1 will map to 192.168.1.1
10.1.1.2 will map to 192.168.1.2
10.1.1.3 will map to 192.168.1.3

By default the SR520 impossible
I can't the router to work at all. I want to default. CCA leaves me no default configuration for this router for some reason any. The box reset config is missing.
I backup upward configs using tftp and then copied the config to factory V9 to the router.
I made a flash copy start then the new mem config then wr
When I reload the router an automatic backup and copy the operation during the start-up
So I did the process again and then made a copy start run and had all kinds of errors.
What exactly is the default method of the router
I'm really starting to think that you should go directly to the TAC. Looks like you had 3 separate issue with this SR520.
Your other post, it seems that we have:
(1) SSL VPN connectivity problems
(2) port forwarding problems
(3) Config reset problems
I'm looking what whether in the common COUNTRY assessment that could contribute to the problem here, but I don't not nailed all the answers yet. (and I hate the idea that you're waiting on something useful here and it does not come fast enough)
I'm still digging.

For the poster who will say "Google is your friend", no it is not, or I wouldn't be here.
I tried for a while now to solve the only problem I have with Snow Leopard Server.
MySql has fallen lion and, apparently, no one knows how to use postgrl so I installed MySql and plundered with her for a few hours to get this working. There were various other issues with Lion. Finally, I went to Yosemite. Hey Apple, where is the GUI? Then at el Capitan and finally tried Sierra (no server app at all yet).
For me, each 'step-up' taking things and running weaker than the last.
Welcome to Snow Leopard. I'll stick with it for a while to come.
The only problem I have with Snow Leopard, it's that when it restarts, the NAT will not start upward. Other than that, it does a magnificent job to maintain my home network. I searched high and low for an answer without success. A few posters who have addressed this problem specifically here never got a response.
As this seems to be about three years or more, since this question was asked and it seems that some have migrated to the SLS, I was wondering if anyone has found a solution.
As it is now, as soon as there is a need to reboot, I just disable the NAT service, restart and turn it back on. In the case of a failure of current (longer than the inverter can maintain) or just a random crash, I have to kill the firewall and NAT then the configuration of the gateway of new service that requires fixing the various omissions and errors and I'm good to go again.
Any help would be greatly appreciated.
You have posted in the forum of Snow Leopard Client. I ask that to move this post. In the meantime, you can see the various forums about this trick:

WRT160N - V3 Xbox NAT strict issue
Xbox 360 NAT issues resolved! (WRT160N v3).
I followed the instructions in the link above, but also at least 20 other posts, but I always get strict NAT with a unique XBOX. I think I tried all combinations and I can't understand why my situation is somewhat different.
Question - when I go to the STATUS, under the 'Internet connection', "IP address" tab, I see 192.168.1.64 (internal address). I read somewhere that in other words, there is an another NAT also beyond my router. What is the problem?
This problem started when I replaced my (default) combination modem/DSL router by an old 2Wire-Homeportal-1000 s, with a brand new Motorola model 2210-02-1022 (modem only) of the AT & T store and combined with a WRT160N V3.
I tried all combinations of UPnP enabled, redirection port, serial port triggering and DMZ range. I used a DHCP reservation to affect my Xbox a static IP address and checked that works very well. But even in the DMZ with UPnP off, I get strict NAT.
I think I have to empty the Motorola + 160N and buy the current combo modem/router 2Wire AT & T, but I do not do that when I don't know for sure there will be more.
Others seem to have great success get this cleared up. Can someone shed light on why none of these techniques work for me?
Thank you
I want to thank you because after endless hours trying to remove the XBOX 360 strict NAT son - your advice finally put me on the right track.
With my particular combination: AT & T DSL, modem Motorola + WRT160N-3 - Bridge mode did not work. As soon as I put the modem in Bridge mode, the light of the Internet on the front does not to come. Maybe, if I called AT & T I could find a way around it. This setting seems to affect the PPOe connection to the router instead of the modem, but some PPOe setting I use (including by providing the user ID and password, etc.) brings me an Internet connection.
What worked was in the modem settings. There was no obvious parameter to enable/disable NAT, instead, it reads: "Let device LAN share Internet address? Choice: "No, use the private IP address", "Yes, use the public IP address. This is the power switch modem NAT and it must be set to Yes (default is NOT which is what created the 2nd NAT).
Even in non bridged mode, with the removed modem NAT, the NAT router and other work now setting. I could put the Xbox successfully in in the demilitarized zone. The idea is, in the STATE of the router tab, you see now a public IP address instead of the internal address of the modem.
WOW that was difficult and time consuming to get to this point!

8.4 ASA using NAT VPN issue.
Hello
I'm working on a customer site and they have a problem with one of their VPN (we have other works well), but it is a major issue and I think it's because we use manual NAT and NAT of the object on the same server for different things.
Traffic between indoors and outdoors:
It works with a specific manual NAT rule of source from the server 10.10.10.10 object
Inside
SRC-> DST
10.10.10.10-> 1.1.2.10 1.1.1.10-> 1.1.2.10 SNAT
= VPN =-> 1.1.2.10 1.1.1.10 1.1.1.10-> 1.1.2.10 <3rd party="" fw=""> It works with a specific using the NAT on the server of 10.10.10.10 object
Remote
SRC-> DST
1.1.1.10-> 1.1.2.10 1.1.1.10-> 1.1.2.10 <3rd party="" fw="">= VPN =-> 1.1.2.10 1.1.1.10
1.1.1.10-> DNAT 10.10.10.10 3rd>3rd>If we have the manual NAT and NAT object it does anyway.
So the question is (as I am new to zip code 8.3 ASA) should not mix the 2 types of NAt and look at configuring it all with manual NAT or NAT object?
With the NAT object out it does not work as it is taken in ouside NAT inside all:
Dynamic NAT (inside, outside) source no matter what interface (this NAT to 1.1.1.1 then does not match the card encryption for VPN)
and I tried a no - nat above that, but that does not work either.
Straws and hugging come to mind try to configure a different config. Any pointers in the right direction would be great.
Kind regards
Z
Hello
I'm not sure that installing even with the explanation. Each NAT configuration I did for VPN used Section 1 Manual / NAT twice.
You have configured the rule by default PAT that you use as Section 1 NAT rule. NAT rules in the new software are divided into 3 sections
- Section 1: Manual / twice by NAT
- Section 2: Purpose NAT
- Section 3: Manual / double NAT (moved to section 3 using the setting "auto after")
- The Sections are passed by from 1 to 2 and 3 in order to find a match.
You should also notice that the Section 1 and Section 3 NAT has "line number" similar to the ACL parameter type. So if you have a default existing PAT rule configured for Section 1 and just add another Section 1 NAT rule without line/order number (VPN NAT) then it will just fall under the existing rule, making the new useless rule.
I would advice against the use of the rule by default PAT as Section 1 NAT rule. Finally, this means that you be constantly watch and edit its configuration when you try to configure more specific rules.
As a general rule 3 of the Section the PAT above default configuration would be the following
NAT (inside, outside) after the automatic termination of dynamic source no matter what interface
This would mean that you need to remove the old. That would mean as naturally as the change would temporarily dismantling all the current connections through "inside", "Outside" while you change the NAT rule format.
If after this configure a NAT twice to the VPN (wihtout the setting "auto after"), it will be the rule in article 1 while the default PAT will be Section 3. Of course, Section 1 will be matched first.
I'm not quite sure of what your setup of the foregoing have understood.
You're just source NAT?
I guess that the configuration you do is something like this?
network of the LAN-REAL object
10.10.10.0 subnet 255.255.255.0

Garage double NAT &; DHCP - bridge Possible issue error
Help...
So it's my game on a yacht...
I have a MacMini (run bootcamp Windows 7 Pro), so actually it's a PC.
- I use internal WiFi adapter of the MacMini to get my internet connection of various different Marina I could stay in
- I then share the connection with the internal LAN adapter WiFi adapter WiFi
- This allows me to share the WiFi port with other devices on the yacht
Then I have an AirPort Extreme-
- I then run an Ethernet on the MacMini Port CAT6 cable
- on port WAN on AirPort Extreme
- AirPort Extreme now has an internet connection (from the marina, WiFi)
- I then activated the WiFi on AirPort Extreme to create a WiFi network on the yacht
- and it gets its internet connection from the WAN port, which comes in turn the MacMini, which in turn comes from the Marina WiFi
Connected to the AirPort Extreme are-
-iPhones, iPads, MacBook, Apple TV, Smart TV, etc etc.
-Some devices are connected using the LAN ports and AirPort Extreme cable
-Some devices are connected by WiFi using WiFi airports
I want DHCP to be handled by the AirPort Extreme-, mode I set as "DHCP and NAT".
What is the problem-
- AirPort Extreme shows an error
- "double NAT and DHCP.
- and suggested I turn it in Bridge mode
- but I don't want to do that
Any thoughts?
Concerning
Tim
Would help if we could get the exact message you see. You will probably need to change the DHCP-range on the AirPort Extreme to a different value, and then use the option 'Ignore' the Double NAT then the airport will show a green light.
You will have to live with the Double NAT if you want AirPort Extreme to act as a remote router that provides a private network.

Question about the issue of the Double NAT...
Hah I posted for a little. I have a question about Double NAT. Is it wise to launch? Reason why is that I have a WRT54G v6 router and the Zoom ADSL X 4 Modem/Router/gateway and it seems that sites take just a little more time to respond to Web sites. I just want to know I have to turn off (i.e., go in with my router bridge Mode) or what. Or leave it alone. Now one last thing: that the problem of slow could actually be AT & T but I have the feeling that this isn't.
What configuration options you have on the Zyxel to fill? What have you tried exactly?
The basis for the first option is:
* Bridged Zyxel.
* Linksys configured for PPPoE with your user name and password for the internet connection.
Instructions to fill the Zyxel are here or here depending on the exact model of Zyxel.
The second option is:
* Zyxel doing business as the router. I assume here that the Zyxel is on 10.0.0.2 with a subnet mask 255.255.255.0.
Unplug the Linksys to the Zyxel. Connect a computer to the Linksys. Open the web interface of the WRT to http://192.168.1.1/
On the main Setup page:
1. change the LAN IP of 192.168.1.1 address 10.0.0.1.
2 disable the DHCP server.
3. save the settings. You will lose the connection. Unplug the computer.
4. wire one of the numbered LAN ports of the Linksys for the Zyxel. Do not use the internet port of Linksys!
Now you should be able to open the Linksys web interface to http://10.0.0.1/ all devices connected wireless of Linksys or connected to one of the three LAN ports must have a connection to the internet via the Zyxel.

My XBOX 360 Live connection was working fine a few days ago. Now, I can't join parties or cats. I was told that this is a NAT problem. No one knows how to fix? I have a WRT54G.
Who is your Internet service provider... ?
Try to reduce the MTU to 1365 and click on the 'Administration' tab and disable the UPnP option and click on save settings... Now, check the connection.
If this does not resolve the problem then try to update firmware of the router.

[Issue] it is possbile to use MCU 4501 on network 1:1 NAT?
Hi, I have a very simple question.
I'll put MCU 4501 model on a private network to connect to public IP codec devices.
Without devices INCAPACITANTS, Turn, or VCS, it works standalone with H323 and its private IP address is set to 1:1 public IP address.
In this position, is that it is possible another codec public IP can join the session of MCU 4501?
In my view, would be well accepted, but given media cannot be accepted because the IP address in the payload would be signaling missmatching.
No one knows about it? or can I use some free public STUN, ENABLE Server H323 Direct mode? or do it by myself?
I have no senior engineer and I have to learn about it, everybody ask me when they stuck on the frame.
This site is the last hope for me, and I'm sorry for imconvient read, it is not my mother tongue.
Thank you.
For H.323, IP address of the port media negotiate during the call setup is not using the IP header.
If your compatible Firewall H.323 AGL, handful of firewall NAT IP and H.323 signal header conversion.
However for MCU, you can consider the firewall on MCU option if you are looking for private/public double network connection.

Just upgraded my ASA 5510 of 8.2 (1) 8.4 (4) 1. Well, everything seems to work with one big exception.
NAT statements I had previously remained in force and even seem to reproduce in some cases.
Now, my question is I've set up a DMZ (security 50) interface and requiring a few servers to connect to the inside interface (Security 100). I created the necessary NAT statements within the ASDM to allow the DMZ servers to connect to a single inside the server. However, all the servers in the DMZ can still ping and connect to ALL inside servers.
An easy way to limit it? I try to limit the number of servers on the internal network that can access the demilitarized zone, but it seems that the DMZ has free rein at the present time.
Am happy to post my configs. I opened a case of TAC, but this firewall is still so new, the assistance contract has not yet been addressed by Cisco.
Thanks in advance.
I'll look when get home, but it is a quick answer.

Design site to Site VPN w/NAT traversal issue
Hi, I have a number of site to site VPN that end on a PIX. I intend to migrate these VPN to a router that sits on a demilitarized zone connected to the PIX. Before doing that I'm going to set up a private network new virtual to end on the router but I also need than VPNS that end on the PIX to be not affected.
If I configure NAT traversal on the PIX, affected my other VPN?
Thanks in advance
DOM
Hi Dom,
Why do you want to configure NAT-Traversal on PIX, if you wish to terminate your VPN router (which is on the DMZ).
Do you do any NAT on PIX thru the router?
If you want to configure NAT-Traversal, it must be configured on the end (on the router in your case) devices.
Example:
When a user with Cisco client or Cisco router behind NAT wants to connect to another device (such as PIX, ASA, or router) NAT - T must be configured on the machine (which will be the PIX or ASA)
Hope that helps.
* Please indicate the post
