Question of failure path reverse NAT

Hello

Using a sense 9.3 3 ASA 5512 - x running. I have Anyconnect VPN configured to PAT the subnet of remote access to one of the inside of the interfaces (because of internal routing restrictions).

For example...

Remote subnet: 192.168.10.0/24

Internal subnet: 192.168.1.0/24

Internal interface: 192.168.1.254

All remote access clients behind 192.168.1.254 and it works correctly until I have add a dynamic NAT rule for outbound traffic, then I start to see the errors "reverse path NAT failure" when VPN clients try to access internal resources.

network of the LAN1 object
subnet 192.168.1.0 255.255.255.0
NAT dynamic interface (indoor, outdoor)

Is there a way to circumvent this problem, because all the remote access clients are hidden behind the interface address?

Thanks for any help.

Hello

Instead of making nat under Group, have you tried to do globally as:

NAT (inside_101_infrastructure, outside) static dynamic source of destination interface LAN-GROUP ANYCONNECT_VPN_SUBNET ANYCONNECT_VPN_SUBNET

Thank you

denied due to failure of reverse path of NAT

I have an ASA5505 (ASDM 7.1 basic licence (3), ASA) 9 () (2) and I am confused about "declined due to the failure of reverse NAT".

My IP pattern is as follows:

INSIDE = 10.0.1.0/24

DMZ =172.16.0.0/24

VPN_Pool = 172.16.20.0/24

PROBLEM: Vpn users can connect to the ASA but can't reach anything on the LAN or DMZ.

TRIAGE: I ran the plotter of package with the following result:

ALB - ASA # packet - trace entry inside tcp 172.16.20.2 1234 172.16.0.2 80

-QUESTION?

The error received is «...» Asymmetrical NAT rules matched for flows forward and backward; Connection for tcp src outside:172.16.20.1/52036(LOCAL\user) DMZ:172.16.0.2/3389 dst refused due to the failure of the path reverse NAT."

What NAT rules I have to apply to allow users access to the LAN/DMZ resources?

Current NAT is the following:

1 (DMZ) to dynamic interface of the DMZ_NET source (outdoor)
translate_hits = 1623, untranslate_hits = 34
Source - origin: 172.16.0.0/27, translated: (MY-real-IP-DELETED) / 21
2 (inside) to the obj_any interface dynamic source (external)
translate_hits = No. 2851, untranslate_hits = 121
Source - origin: 0.0.0.0/0, translated: (MY-real-IP-DELETED) / 21

THANKS IN ADVANCE FOR HELP!

The pool of addresses for VPN users must have an exemption for all DMZ NAT or inside networks, they will use. They appear as out of addresses (even if they receive a local private IP address) based on their interface of penetration.

Therefore, without an exemption from costs of NAT, traffic back to them is NATted by one of your two NAT rules above (while incoming traffic was not NATted). So the message of «asymmetric NAT rules» matched to flow forward and backward

Your plotter package them specified as inside and so you have a false positive indication would be given to the movement.

ASA 5505 as internet gateway (must reverse NAT)

Hi all the Cisco guru

I have this diet:

Office-> Cisco 877-> Internet-> ASA 5505-> remote network

Office network: 192.168.10.0/24

Cisco 877 IP internal: 192.168.10.200

Cisco 877 external IP: a.a.a.a

ASA 5505 external IP: b.b.b.b

ASA 5505 internal IP: 192.168.1.3 and 192.168.17.3

Remote network: 192.168.17.0/24 and 192.168.1.0/24

VPN tunnel is OK and more. I have the Office Access to the remote network and the remote network access to the bureau by the tunnel.

But when I try to access the network remotely (there are 2 VLANS: management and OLD-private) to the internet, ASA answer me:

305013 *. * NAT rules asymetrique.64.9 matched 53 for flows forward and backward; Connection for udp src OLD-Private:192.168.17.138/59949 dst WAN:*.*.64.9/53 refused due to path failure reverse that of NAT

Ping of OLD-private interface to google result:

Result of traceroute

How can I fix reverse NAT and make ASA as internet gateway?

Why you use this NAT type?

Access extensive list ip 192.168.17.0 WAN_nat0_outbound allow 255.255.255.0 any
NAT (OLD-private) 0-list of access WAN_nat0_outbound

You are basically saying the ASA not NAT traffic. This private IP address range is not routed on the Internet. This traffic is destined to be sent over the Internet? If so, that LAC should then not be there.

If you want NAT traffic to one IP public outside the ASA, you must remove this line and let the NAT and GLOBAL work:

NAT (OLD-private) 1 0.0.0.0 0.0.0.0

Global (WAN) 1 interface

On the Question of VPN S2S source NAT

Currently we have a number of implementation of VPN with various clients. We are NAT'ing range them at a 24 in our network to keep simple routing, but we seek to NAT Source our resources due to security problems. It is an example of a current virtual private network that we have configured:

outside_map crypto card 5 corresponds to the address SAMPLE_cryptomap

outside_map 5 peer set 99.99.99.99 crypto card

card crypto outside_map 5 set ikev1 transform-set ESP-3DES-MD5 SHA-ESP-3DES

card crypto outside_map 5 the value reverse-road

My question revolves around the Source NAT configuration. If I understand correctly, I have to configure 3 statements of NAT per NAT Source since there are three different destinations that are NAT' ed. I think I would need to add this:

Is that correct, or is at - it an easier way to do this without having to add all statements of NAT? Moreover, any change would be to do on the access list?

Hello

To my knowledge you should not create several new instructions from NAT. You should be well just create a new Group 'object' for new addresses your source address NAT.

To better explain, take a look at your current ' object-group ' that defines your source addresses

the APP_CLIENT_Hosts object-group network

network-object, object SITE1_APP_JCAPS_Dev_VIP

network-object, object SITE1_APP_JCAPS_Prod_VIP

network-object, object SITE2_APP_JCAPS_Dev_Host

network-object, object SITE2_APP_JCAPS_Prod_VIP

network-object, object SITE1_APP_PACS_Primary

Now you can do this sets up a "object-group" that contains a NAT IP address for each of the IP addresses inside the ' object-group ' and 'object' used above. The IMPORTANT thing is that the ' object-group ' that contains the NAT IP addresses is in the SAME ORDER as the actual source addresses.

I mean, this is the first IP address is in most object - group ' will correspond to the first IP address in the newly created "object-group" for the IP NAT addresses.

As above, you can simply have the same "nat" configurations 3 as before but you change/add in the newly created "object-group"

For example, you might do the following

network of the SITE1_APP_JCAPS_Dev_VIP_NAT object

Home 88.88.88.81

network of the SITE1_APP_JCAPS_Prod_VIP_NAT object

Home 88.88.88.82

network of the SITE2_APP_JCAPS_Dev_Host_NAT object

Home 88.88.88.83

network of the SITE2_APP_JCAPS_Prod_VIP_NAT object

Home 88.88.88.84

network of the SITE1_APP_PACS_Primary_NAT object

Home 88.88.88.85

the APP_CLIENT_Hosts_NAT object-group network

network-object, object SITE1_APP_JCAPS_Dev_VIP_NAT

network-object, object SITE1_APP_JCAPS_Prod_VIP_NAT

network-object, object SITE2_APP_JCAPS_Dev_Host_NAT

network-object, object SITE2_APP_JCAPS_Prod_VIP_NAT

network-object, object SITE1_APP_PACS_Primary_NAT

Then you add the following configurations of "nat"

NAT (inside, outside) 1 static source APP_CLIENT_Hosts APP_CLIENT_Hosts_NAT CLIENT_Host_1_NAT CLIENT_Host_1 non-proxy-arp-search of route static destination

Static NAT APP_CLIENT_Hosts APP_CLIENT_Hosts_NAT static destination CLIENT_Host_2_NAT CLIENT_Host_2 non-proxy-arp-search of source route 2 (inside, outside)

NAT 3 (indoor, outdoor) static source APP_CLIENT_Hosts APP_CLIENT_Hosts_NAT CLIENT_Host_3_NAT CLIENT_Host_3 non-proxy-arp-search of route static destination

Note line numbers, we added the above commands. This allows them to enter the upper part of the ASAs NAT rules, and therefore, they will become active immediately. Without line numbers that they will only be used after when you remove the old lines.

Then you can remove the "old"

no nat source (indoor, outdoor) public static APP_CLIENT_Hosts APP_CLIENT_Hosts CLIENT_Host_1_NAT CLIENT_Host_1 non-proxy-arp-search of route static destination

no nat source (indoor, outdoor) public static APP_CLIENT_Hosts APP_CLIENT_Hosts CLIENT_Host_2_NAT CLIENT_Host_2 non-proxy-arp-search of route static destination

no nat source (indoor, outdoor) public static APP_CLIENT_Hosts APP_CLIENT_Hosts CLIENT_Host_3_NAT CLIENT_Host_3 non-proxy-arp-search of route static destination

This should leave you with 3 configurations "nat" who made the NAT source addresses and destination.

Naturally while you perform this change you will also have to change the ACL Crypto to match the new source NAT. This is because as all NAT is done before any VPN on the ASA. So the destination addresses are Nations United for before VPN and source addresses are translated before VPN.

If you do not want to make the changes without affecting the connections too so I suggest
- Add rules to the ACL Crypto for new addresses (NAT) source. Of course, this must be done on both sides of the VPN L2L. You would still be leaving the original configurations to the Crypto ACL does not not the functioning of the L2L VPN.
- Add new configurations of "nat" above without the line numbers I mentioned who mean you that they wont be used until you remove the "old".
- When you are ready to be migrated to use the new IP addresses, simply remove the original "nat" configurations and the ASA will start the corresponding traffic for new "nat" configurations. Provided of course that there is no other "nat" configuration before the nine that could mess things up. This should be verified by the person making the changes.
Of course if you can afford a small cut when then changing the order in which you do things should not matter that much. In my work, that connections are usually not that critical that you can't make these changes almost at any point as it is a matter of minutes what it takes to make changes.

Hope this made sense and helped

2. is there an advantage to making it be bootable?
3. If so, how I would be bootable?
4. is it possible to copy the contents of the current time machine disk to the new disk? The old time machine disk drive is 500 GB, and I don't have 500GB free on my disk system hae. Should I just unplug the old drive and I only connect if I can't find a file? In addition, 500 GB drives no longer seem to be available. The smallest drive available now is 1 TB.
5. Is it possible that the failures of time machine, I had are with the time machine of tine software, not the drive? I'm under mountain lion. I don't want to update to OSX, because I do not know if all applications will break.
6. the reason why I asked question 5 is that when the disc goes down, I disable the mac, disconnect/reconnect the time machine, turn on mac. It is possible that the mac start-up is enough, and I don't need to disconnect/reconnect the time machine. Thoughts here?

1 mac OS extended (journaled).

2 & 3. I don't know the answer to these questions.

4. try to use disk/restore to copy the backup to a new location. Please note that this will reformat the destination partition.

5. more than information would be useful. What type of chess?

6. reboot may be sufficient.

Adobe Captivate Question 9-Animation (path)

I am currently working in Adobe Captivate 9 and fight with some paths. I've got some grouped items (an example: a piece of the puzzle is grouped with a text box) and want to evolve together on a path. This trajectory looks great in the preview, the preview of HTML5, etc.. However, when I publish it as a file zip for my E-Learning review, it looks nothing like the preview or preview of html5. The piece of the puzzle is in one place, and the text ends by not moving does not regarding - as they seek is more as if they are grouped.
In another example of this same question, groups I put movement paths on did not end with the position that they appeared at the end in HTML5 preview or overview screen.
You cannot apply a trajectory groups? Does anyone else have this problem? How can I solve it?

You can apply trajectories to groups, but it is a little tricky. It is the focal point of the group following the path.

Alternatively, you can check your version number? There are questions for the output in the first version. The current version is 9.0.1.320

question of iSCSI paths

Hello
I try multi-trip, the iscsi target server has two network adapters and ESX has three NICs binded and created three VMKernel.
Here is the information of iSCSI storage card:
Here's a path to manage:
Why only show six paths? It is 18 paths?
Thank you!

It only displays the LUNS real (6) and now total access roads (3) you have.

New Guy Question - Disable Multi-Pathing on the VCB Proxy Server

Hello everyone
I had to install a Solution of the VCB Proxy. Among the issues is "Disabling Multi-Pathing on the VCB Proxy Server.
Why would it be necessary to disable the multiple paths on th e VCB Server? What would be the steps to disable the multiple paths.
Thank you all for any input on this issue.

question about URLRequest (path?)

IM new here, I want that patn is valid for URLRequest
var varSend:URLRequest = new URLRequest ("config_flash.php");
only valid if I put my .fla file in the same folder?
var varSend:URLRequest = new URLRequest ("C:\config_flash.php");
can it run perfectly to drive C?
var varSend:URLRequest = new URLRequest ("http://localhost/project/config_flash.php");
or just run in the folder on the server ASIN?

var varSend:URLRequest = new URLRequest ("config_flash.php");

only valid if I put my .fla file in the same folder?

By using the relative path is fine, but this should be the target of the swf file where it resides, if you embeded in HTML it should aim at the trajectory of html.

Question: Model a path? (not of race or pattern fill!)

I have a logo where I create a small single lamp as a reason, just a couple of flame red-yellowish but easily repetitive, nothing special. Now the problem is I want to create a round timber and put this model flame outside the logo, the circle of the path of the main logo.
I found only one way to do it, using polar cordinates filter/distortion/polar cordinates. However that greatly deform the model.
Any easy ideas how to proceed? Even without using the template, I don't mind if I have to do differently from the use of the model.
Thanks in advance!

It is an example of the polar coordinates filter. Top the original pattern, downstairs, that's what it looks like to your after.

NAT error ASA 5505 to 5510

Connection refused because of the failure of path opposite of that of NAT

I put a second location of ASA and not can communicate through the VPN is implemented. The error I get is (rules asymmetrical NAT matched for flows forward and backward; Connection for icmp outside CBC: 192.168.72.14 internal dst: 192.168.73.103 (type 0, code 0) rejected due to the failure of reverse NAT) when trying to ping a host on the network iinsde the 73 to a host within the network of 72.

I mirrored the statements of nat VPN work. I see an ACL to a group of objects but don't see where this is important. Am I missing something obvious?

Any suggestion would be greatly apperciated

You may need to remove the following ASA remote. I don't know what it is for

NAT (dmz, external) NETWORK_OBJ_192.168.73.0_24 NETWORK_OBJ_192.168.73.0_24 Shared static source 192.168.72.0 destination 192.168.72.0

Asymmetric NAT rules

I am trying to configure another ipsec VPN group and political. So far, I can communicate with her, and I can ping the ASA 5505, but nothing else inside. The funny this is that I have another configuration group and the policy that works very well. I tried to imitate him, but I can't understand what I'm doing wrong. I get this error in the log:

Asymmetrical NAT rules matched for flows forward and backward; Connection for icmp src, dst outside: 10.4.71.104 inside: 10.4.70.2 (type 8, code 0) rejected due to the failure of reverse NAT.

A network diagram is attached. Thanks for your help.

Andy,

Yes 8.3 makes a difference

Well I can suggest a few ways out of it.

And that's what you need to add... kind of nat provides previous versions.

NAT (inside, all) source static obj - 10.4.70.0 obj - 10.4.70.0 destination static obj - 10.4.71.0 obj - 10.4.71.0

Edit: fixed IP addresses. If 10.4.70.0/24 is local and remote 10.4.71, you need to add an exemption here.

Remote VPN cannot access devices LAN or internet

So I have a server and a computer inside that I can access through an ASA 5505 with ASA 9.2 (1) and ASDM 7.2 (1)

The computer on 192.168.1.110 via port 8080 can show me a demo site.

The server on 192.168.1.222 got my DNS, HTTP, FTP, mail and more about it.

Outside, I got a computer (by outside, I hear from the firewall and the cable directly into the computer) on 192.168.20.2 and firewall outside being 192.168.20.1

From the outside I can access the 8080 without problem (and I guess as well with the server, but it is on another default gateway and are not accessible right now). -When I connect through my VPN I am assigned 192.168.30.5 but unable to connect inside the computer through 192.168.1.110:8080.

This will return the error: asymmetrical NAT rules matched for before and back flow; Connection for udp src outdoors: 192.168.30.5/49608 (...) dst inside: 192.168.1.222/53 refused because of the failure of the path reverse NAT.

Somewhere, I had a conflict or a non-created access rule. Anyone who wants to take a shot?

I marked with "BOLD" for what I thought that may be the cause.

Hello

"Nat" bold configuration is incorrect, as you would expect.

Replace it with something like this

the object of the LAN network
subnet 192.168.1.0 255.255.255.0

NAT (inside, outside) 1 static source LAN LAN to static destination HOST-VPN-VPN-HOST

I also suggest using a separate access the ACL of the Tunnel from Split 'standard' list.

For example

standard SPLIT-TUNNEL access list permit 192.168.1.0 255.255.255.0

Naturally, you must pass the ACL above to used "group policy" .

In addition, if you want to control the incoming connections to VPN users in 'outside_access_in' ACL, then you could change the default settings on the SAA by running the command

No vpn sysopt connection permit

If you need to return back then just to deliver without 'no' in front. Then back to its default value. This does not show in the running configuration by the way.

With this setting all connections from VPN connections should be allowed on the interface ACL interface that ends the VPN connection. If in your case that would be the ACL attached to the 'outside' interface.

Hope this helps :)

Peer AnyConnect VPN cannot ping, RDP each other

I have an ASA5505 running ASA 8.3 (1) and ASDM 7.1 (1). I have a remote access VPN set up and remote access users are able to connect and access to network resources. I can ping the VPN peers between the Remote LAN. My problem counterparts VPN cannot ping (RDP, CDR) between them. Ping a VPN peer of reveals another the following error in the log of the SAA.

Asymmetrical NAT rules matched for flows forward and backward; Connection for icmp outside CBC: 10.10.10.8 outside dst: 10.10.10.9 (type 8, code 0) rejected due to the failure of reverse NAT.

Hello

Seems to me that you can clean the current NAT configuration a bit and make it a little clearer.

I suggest the following changes

network of the VPN-POOL object

10.10.10.0 subnet 255.255.255.0

the object of the LAN network

subnet 192.168.1.0 255.255.255.0

PAT-SOURCE network object-group

object-network 192.168.1.0 255.255.255.0

object-network 10.10.10.0 255.255.255.0

NAT static destination LAN LAN (indoor, outdoor) static source VPN-VPN-POOL

destination VPN VPN-POOL POOL static NAT (outside, outside) 1 static source VPN-VPN-POOL

NAT interface (it is, outside) the after-service automatic PAT-SOURCE dynamic source

The above should allow
- Dynamic PAT for LAN and VPN users
- NAT0 for traffic between the VPN and LAN
- NAT0 for traffic between the VPN users
You can then delete the previous NAT configurations. Naturally, please save the configuration before you make the change, if you want to revert to the original configuration.

no static source nat (inside, everything) all electricity static destination RAVPN RAVPN

No source (indoor, outdoor) nat static static NETWORK_OBJ_10.10.10.0_28 destination NETWORK_OBJ_192.168.1.0_24 NETWORK_OBJ_192.168.1.0_24 NETWORK_OBJ_10.10.10.0_28

No source (indoor, outdoor) nat static everything all NETWORK_OBJ_10.10.10.0_28 of NETWORK_OBJ_10.10.10.0_28 static destination

No network obj_any object

No network object RAVPN

In case you do not want to change the settings a lot you might be right by adding this

network of the VPN-POOL object

10.10.10.0 subnet 255.255.255.0

destination VPN VPN-POOL POOL static NAT (outside, outside) 1 static source VPN-VPN-POOL

But the other above configurations changes would make NAT configurations currently simpler and clearer to see every goal of "nat" configurations.

ASA5505 SSL AnyConnect VPN and NAT Reverse Path failure

I worked on it for a while and just have not found a solution yet.

I have a Cisco ASA5505 Setup at home and I try to use the AnyConnect VPN client to it. I followed the example of ASA 8.x split Tunnel but still miss me something.

My home network is 10.170.x.x and I install the VPN address to 10.170.13.x pool I have a Windows workstation running at 10.170.0.6, printers 10.170.0.20 and 21 and inside the router itself is 10.170.0.1

I can connect from the outside and am assigned an IP address of 10.170.13.10, but when I try to access network resources via ICMP or open a web page, the newspaper of the ASDM shows a bunch of this:

I tried several things with NAT, but were not able to go beyond that. Does anyone mind looking at my config running and help me with this? Thanks a bunch!

Couple to check points.
