Configuration VPN - NAT - T support
Hello
A partner of business (BP) has the following requirements. I don't know which statements of config I need to use to ensure this successful connection
Business (BP) needs partner complete the VPN tunnel on a firewall that is behind another firewall running NAT
(BP) will create UDP 500 and UDP 4500 endpoints on the NAT firewall which is forwarded to the Firewall VPN termination.
Because of this, the (BP) needs of my dissertation support encapsulation of ESP over UDP (NAT - T)
My series of ASA5500 using the code (825) has the statements
Crypto isakmp nat-traversal 21
crypto ISAKMP ipsec-over-tcp port 10000
VPN # match address BP_VPN crypto card
VPN # set peer (peer_ip) crypto card
VPN # game of transformation-AES_256_SHA crypto card
IPSec-l2l type tunnel-group (peer_ip)
IPSec-attributes of tunnel-group (peer_ip)
pre-shared key (TBD)
BP_VPN list extended access permit tcp host 10.x.x.x, 172.16.x.x eq (specified port) host
BP_VPN list extended access permit tcp host 10.x.x.y host 172.16.x.x eq (specified port)
NatExempt_VPN list extended access permit tcp host 10.x.x.x, 172.16.x.x eq (specified port) host
NatExempt_VPN list extended access permit tcp host 10.x.x.y host 172.16.x.x eq (specified port)
Please indicate whether these statements are sufficient and if not what else would be needed.
You need not order
crypto isakmp ipsec-over-tcp port 10000It is for the exclusive implementation that was used before NAT - T is available. You only need to nat-traversal active. For your ACL, using ports in there makes everything complicated. You should see if you can just use 'ip' here. If there is already configured on your ASA virtual private networks, then the config is probably ok. If this isn't the case, you must always configure ISAKMP and activate the encryption on the interface card.

Need help to configure VPN NAT traffic to ip address external pool ASA
Hello
I need to configure vpn NAT ip address traffic external pool ASA
For example.
Apart from the ip address is 1.1.1.10
VPN traffic must be nat to 1.1.1.11
If I try to configure policy nat or static nat ASA gives me error "global address of overlap with mask.
Please, help me to solve this problem.
Thank you best regards &,.
Ramanantsoa
Thank you, and since you are just 1 IP 1.1.1.11 Polo, the traffic can only be initiated from your site to the remote end.
Here is the configuration of NAT:
access list nat - vpn ip 192.168.1.0 allow 255.255.255.0 10.0.0.0 255.255.0.0
NAT (inside) 5 access list nat - vpn
Overall 5 1.1.1.11 (outside)
In addition, the ACL crypto for the tunnel from site to site should be as follows:
access-list allow 1.1.1.11 ip host 10.0.0.0 255.255.0.0
Hope that helps.

I am interested in establishing a VPN for my computer. I looked at some of the information to help Ms. I'm missing something in the way of understanding how do or end the connection.
You can configure VPN regardless of static or dynamic IP, both are possible. You can refer to:

We have a partner that we set up a VPN L2L with. Their internal host IP infringes on our internal IP range. Unfortunately, they are not offer NAT on their side. Is it possible on the SAA to configure a NAT device for my internal hosts will say 1.1.1.1 and ASA changes the internal address of the remote end overlapping?
If this is the scenario
192.168.5.0 ASA1 <---> <-- internet="" --="">ASA2<-->
ASA1 (NAT will be applied)
ASA2 (without nat will be applied)
You want to do something like that on ASA1
Change your source host or network to be 192.168.7.0 when communicating with the remote network. Change the remote network to come as long as 192.168.8.0 coming to your network on the SAA.
ACL soccer match:!-match-list ACLaccess acl_match_VPN ip 192.168.7.0 allow 255.255.255.0 192.168.5.0 255.255.255.0

Complete the VPN configuration using acl_match_VPN as the ACL match. Your inside host will have to use the 192.168.7.0 network when you talk to the remote end.
I hope this helps.

Site to Site VPN of IOS - impossible route after VPN + NAT
Hello
I have problems with a VPN on 2 routers access 8xx: I am trying to set up a quick and dirty VPN Site to Site with a source NAT VPN tunnel endpoint. This configuration is only intended to run from one day only inter. I managed to do the work of VPN and I traced the translations of NAT VPN tunnel endpoint, but I couldn't make these translated packages which must move outside the access router, because intended to be VPN traffic network is not directly connected to leave the router. However, I can ping the hosts directly connected to the router for access through the VPN.
Something done routing not to work, I don't think the NATing, because I tried to remove the NAT and I couldn't follow all outgoing packets that must be sent, so I suspect this feature is not included in the IOS of the range of routers Cisco 8xx.
I'm that extends the features VPN + NAT + routing too, or is there a configuration error in my setup?
This is the configuration on the router from Cisco 8xx (I provided only the VPN endpoint, as the works of VPN endpoint)
VPN endpoints: 10.20.1.2 and 10.10.1.2
routing to 192.168.2.0 is necessary to 192.168.1.2 to 192.168.1.254

Hi Jürgen,
First of all, when I went through your config, I saw these lines,
!
interface Vlan2
IP 192.168.1.1 255.255.255.248
!
!
IP route 192.168.2.0 255.255.255.0 192.168.1.254
!
With 255.255.255.248 192.168.1.1 and 192.168.1.254 subnet will fall to different subnets. So I don't think you can join 192.168.2.0/24 subnet to the local router at this point. I think you should fix that first.
Maybe have 192.168.1.2 255.255.255. 248 on the router connected (instead of 192.168.1.254)
Once this has been done. We will have to look at routing.
You are 172.31.0.2-> 192.168.1.11 natting
Now, in order for that to work, make sure that a source addresses (192.168.1.11) NAT is outside the subnet router to router connected (if you go with 192.168.1.0/29 subnet router to router, with 192.168.1.1/29 on the local router and 192.168.1.2/29 on the connected router as suggested, it will be fine). So in this case 192.168.1.8/29 to the subnet that your NAT would be sources fall.
Have a static route on the router connected (192.168.1.2) for the network 192.168.1.8/29 pointing 192.168.1.1,
!
IP route 192.168.1.8 255.255.255.248 192.168.1.1
!
If return packets will be correctly routed toward our local router.
If you have an interface on the connected rotuer which includes the NAT would be source address range, let's say 192.168.1.254/24, even if you do your packages reach somehow 192.168.2.0/24, the package return never goes to the local router (192.168.1.1) because the connected router sees it as a connected subnet, so it will only expire
I hope I understood your scenario. Pleae make changes and let me know how you went with it.
Also, please don't forget to rate this post so useful.

Help please - configuration VPN AnyConnect crossed
Hi there, forgive me if I missed all the protocols forum because this is my first post.
I am trying to configure an AnyConnect VPN and I think it's nearly there, but not enough yet. When I connect from an outside network, it gives me the following error '... No address is available for an SVC connection. I checked the pools of addresses and what I see, they are assigned to the profile. I'm doing it also crossed, I all VPN traffic through this router... traffic LAN and remote Internet sometimes when I'm on the unfamiliar wifi hotspots. I tried to get this to work for more than 1 week with a lot of different forums to scouring. I have included my config running for anyone to help me with. I appreciate a lot of the answers to get me on the right track. Thank you.
Update 15 minutes later: I posted my SSLVPN IP pool to the DefaultWebVPNGroup and it connected but I was unable to browse the web or ping network resources. I would like to disable the "DefaultWebVPNGroup" without any consequences for the installation program. What I still have to disable?

Thanks again to all.
To access the internal resources of VPN, here's what needs to be configured for NAT:
obj-SSL-pool of network objects
192.168.132.0 subnet 255.255.255.0
object obj-Interior-LAN network
192.168.123.0 subnet 255.255.255.0
Static NAT obj-Interior-LAN obj-Interior-LAN destination source (indoor, outdoor) obj-SSL-pool static obj-SSL-pool
I also advise you to remove the following statement of the NAT:
NAT (exterior, Interior) source Dynamics one interface
If you want all traffic internet VPN to be routed to the tunnel, then here's the NAT config:
object obj-SSL-internet network
192.168.132.0 subnet 255.255.255.0
dynamic NAT interface (outdoors, outdoor)
And finally, you cannot disable the group policy by default 'DefaultWebVPNGroup '. So that when you log-in, you chose
SSLVPN_users group of tunnel, which will apply SSLVPN automatically group policy that you have configured explicitly that.
I hope this helps.

LT2P configuration vpn cisco asa with the internet machine windows/mac issue
Dear all,
I have properly configured configuration vpn L2TP on asa 5510 with 8.0 (4) version of IOS.
My internet does not work when I connect using the vpn. Even if I give power of attorney or dns or I remove the proxy
It does not work. only the resources behind the firewall, I can access. I use the extended access list
I tried also with the standard access list.
Please please suggest what error might be.
Thank you

Split for L2TP over IPSec tunnel tunnel is not configured on the head end (ASA), it must be configured on the client itself, in accordance with the following Microsoft article:

Configure the nat directional bi
Hello
I have a problem with some mail servers reject some of our mail, because our mail server address goes off on is not the same as it is resolved to.
This is because I have configured the following:
public static x.x.161.101 (Interior, exterior) tcp smtp smtp Exchange1 netmask 255.255.255.255 0 0
(which covers the outside)
then:
NAT (inside) 1 0.0.0.0 0.0.0.0 0 0
Global 1 interface (outside)
(giving a different address for the Interior post outdoors)
I thought that the static method would cover bidirectional nat'ing.
I don't know how I can fix it.
Thank you
Sam
Yes, I think that your best option is to assign a public ip address dedicated to the mail server.
However, you can try this configuration using "NAT"policy:
sender of the access permit tcp host Exchange1 list any eq smtp
NAT (inside) 2-list of access mailer
Global x.x.161.101 2 (outdoor)
Please let me know if it works

Please give index on configuring vpn site to site on 881 to ASA 5505 cisco router
Earlier my boss asked me to prepare to implement the VPN site-to site on router Cisco 881 Integrated Services to ASA 5505 router, which is now running on the side of HQ. Someone please give me a hint. I am now learning the pdf file from Cisco that mention how to configure VPN site to site between 1812 Cisco IOS router and router of the ASA 5505 using ASDM V6.1 and SDM V2.5. Cannot find the book for the Cisco 881 device.
Someone please please suggest me something as soon as POSSIBLE.

VPN you have problem with ping to a server after you configure a NAT
My VPN worked very well until the Exchange Server client has added and changed my setup.
Once the customer added the Exchange Server and edited my setup, my VPN you problem.
I've corrected some but there's always a them that I can not ping to exchange the local ip address of the server (192.168.1.2).
One thing I notice, is that I can ping this IP 192.168.1.2 if I remove ' ip nat inside source static 192.168.1.2 extensible 116.xx.xx.xx.
Someone please check the configuration below and advise me.
I would be very appreciate any kind of suggestion.
Thank you.

NATting is done before the encryption.
So if you want to access the server via its private IP address you must make sure you exclude the traffic to and from users VPN to be translated (route-map on the instruction of NAT is a typical way).
Otherwise move to DVTI database solution that should not be affected by this problem.

VPN IPSec running but you have to configure the NAT
I just established an IPsec VPN with one of our prividers, the EEG established VPN but the addresses in my LAN IP is in conflict with a device in my side suppliers. I am trying to configure NAT in order to avoid the conflict, but I'm naïve markets do.
This is part of my current configuration

the customer_inside object-group network

Thanks for your help.
Hello Rafael,.
You can do it with a nat policy:
The host ip X.X.X.X 255.255.255.248 192.168.1.25 allowed access list TEST
public static 192.168.20.25 (inside, outside) TEST of the access list.
As nat goes first cryptography for VPN traffic, you'll need to include in the list of ACL of Crypto traffic from natted ip address (in this case 192.168.20.25).
Kind regards

WRT1900AC cannot configure VPN
I CURRENTLY HAVE 2 WIRELESS ROUTERS AN ASUS RT-N56U WHICH WAS EASY to set UP WITH ExpressVPN. COMING TO EXPAND MY NETWORK & IMPROVE USING A LINKSIS WRT1900AC. UNABLE TO SET TO THE TOP OF THE SAME. BOTH ROUTERS ARE HARD CABLES TO THE ISP ROUTER & WILL BE POSITIONED AT DIFFERENT AREAS OF THE HOUSE FOR COVER. I HAVE THE ExpressVPN PAST & DETAILS USER password, LIST OF GLOBAL SERVER ADDRESSES & THEIR ADDRESSES IP CONCERNED.
CAN SOMEONE HELP ME IN THE BASIC CONFIGURATION. I AM NOT AN IT WIZZ BUT YOU CAN FOLLOW THE INSTRUCTIONS ESPECIALLY WITH SCREENSHOTS SUPPORTED. HELP IS GREATLY APPRECIATED.
OK gents,
Answers very well. It gives me a lot to think so thank you very much.
Temporarily, I currently have 2 routers connected switch wired to asus to linksys with the linksys being connected on the local network of the asus through the cable network. The asus is configured as L2TP that allows the details of user, password & VPN server. Use them in this way gives me the IP addresses associated with the address of the server used. This IP address is provided if connected to a router. Probably not the fastest or the best way but will suffice until I have work on your tech talk. I have an ASUS RT - 68U (which has the VPN Client) available to replace the Asus RT - 56U to come. I can use the 56U on the edge of the property similar to the linksys. Trial & error prototyping will I hope make me it in the absence of knowledge or understanding.
Can someone advise on potential pitfalls with the current configuration or plans for the future?
Thanks again.

BlackBerry 10 auto-configuration VPN connection on Wifi networks
Dear all
Soon-to-be owner of a Z10, I try to have a smooth start once it arrives. How would I go about establishing an automatic VPN connection to connect to certain Wifi (public, non-free)? Is it still possible?
The VPN connection offer me free access to these networks, but it is quite annoying to always have to manually open the VPN when one of them is in scope.
Thank you, Florian
Hi floriparate and welcome to the community of BlackBerry Support Forums!
Settings > network connections > Wi - Fi > saved, select the saved network and then add the VPN profile to configure auto-connect when it is connected to this network.
This article will provide more information on the creation of a VPN on your BlackBerry Z10 profile.

Hi all
Just a mental block, I feel at the moment.
ASA 5585 code 9.0.x race - there is no NAT configuration at all on the box. This ASA firewall will end a site to site VPN. -
My question is - is a rule of "NAT exemption" required... .similar to the crypto ACL for the traffic in the tunnel... .or is NAT exemption required only when NAT is configured.
My apologies if this is a silly question
Thank you
James
When there is no NAT config, the ASA will pass all traffic not translated, which includes the traffic tunnel. If you're right, you don't need any NAT exemption.
However, you can configure it. For example, if you plan to add NAT at a later stage, then it might be easier to implement than NAT if your NAT exemption is already in place.

I need to configure NAT on a VPN tunnel to accomplish the following. I already have the tunnel upward and running just need to confirm my NAT config.
ASA 8.2 Version running (5)
I only need to set up A
The internal subnet to site A is 172.30.6.0/24 and I need NAT this subnet to 172.31.183.0/24 when the destination subnet is 172.31.255.128/25
So here's what I thought.
Policy NAT 172.30.6.0/24 to 172.31.183.0/24 the translation when the destination is 172.31.255.128/25.
Public static 172.31.183.0 (inside, outside) - CBC-NAT-TRANSLATION access list
CBC-NAT-TRANSLATION scope ip 172.30.6.0 access list allow 255.255.255.0 172.31.255.128 255.255.255.128
Then I would need that
Public static 172.31.255.128 (exterior, Interior) 172.30.6.0 netmask 255.255.255.0
That sounds about right.
Thank you
Mike

As I said that I did not use a network with a static NAT strategy, so I don't know if the host part of the IP address matches the host Party in the range NAT if you see what I mean.
It could, but it cannot be a concern for you anyway. You would need to watch the xlate table once you make the connection to know for sure.
In addition, it means all devices in this subnet may send packets to each device in the remote subnet but once again can not be a cause for concern.
But apart from that, Yes, your config seems fine for me.
I try with the first beach and establish a connection and then if it works check the xlate dashboard to see exactly what IP he chose.
