Remote Access VPN and NAT inside interface
Hi everyone,
I have configured Remote VPN access.
Inside interface and vpn pool is 10.0.0.0 subnet.
ASA inside interface has NAT exempt as per config below
nat (inside,outside) source static NETWORK_OBJ_10.0.0.0_24 NETWORK_OBJ_10.0.0.0_24 destination static NETWORK_OBJ_10.0.0.0_25 NETWORK_OBJ_10.0.0.0_25 no-proxy-arp route-lookup
object network NETWORK_OBJ_10.0.0.0_24
subnet 10.0.0.0 255.255.255.0
object network NETWORK_OBJ_10.0.0.0_25
subnet 10.0.0.0 255.255.255.128
Also i have ASA inside interface connected to R1 as below
R1 ---10.0.0.2------------inside int IP 10.0.0.1--------ASA
R1 has loopback int 192.168.50.1 and ASA has static route to it.
When i connect to remote access vpn i can ping the IP 192.168.50.1 from My pc which is connected to outside interface of ASA.
This ping works fine.
Mar 04 2014 21:58:27: %ASA-6-302020: Built inbound ICMP connection for faddr 10.0.0.52/1(LOCAL\ipsec-user) gaddr 192.168.50.1/0 laddr 192.168.50.1/0 (ipsec-user )
Mar 04 2014 21:58:28: %ASA-6-302021: Teardown ICMP connection for faddr 10.0.0.52/1(LOCAL\ipsec-user) gaddr 192.168.50.1/0 laddr 192.168.50.1/0 (ipsec-user) Mar 04 2014 21:58:27:
Need to understand how this ping works without exempting 192.168.50.0 from natiing
or
how does nat work for above ping from 10.0.0.52 VPN user PC IP to loopback interface of R1 in regards to NATing?
Regards
Mahesh
Hi Jouni,
IP address to PC is 10.0.0.52 ---------Assigned to Client PC.
Leting you know that i have removed the NAT below config from inside to outside interface
ASA inside interface has NAT exempt as per config below
nat (inside,outside) source static NETWORK_OBJ_10.0.0.0_24 NETWORK_OBJ_10.0.0.0_24 destination static NETWORK_OBJ_10.0.0.0_25 NETWORK_OBJ_10.0.0.0_25 no-proxy-arp route-lookup
object network NETWORK_OBJ_10.0.0.0_24
subnet 10.0.0.0 255.255.255.0
object network NETWORK_OBJ_10.0.0.0_25
subnet 10.0.0.0 255.255.255.128
Still ping works fine from VPN client PC to IP 192.168.50.1

So question is how ping from outside is working without nat exempt from inside to outside?
So does second packet tracer proves that i have no NAT config from loopback to outside and ping works because i have NO NAT configured?

Remote Access VPN, how to specify on which interface clients will be placed on?
Hi,
I have a general understanding problem with remote access VPN and Cisco ASA.
If I have an ASA with multiple interfaces and I want to make sure that a Remote Access VPN Client is placed onto a specific interface, how do I do this?
example:
ASA has 4 interfaces: outside, inside-clients, inside-workers, inside-lab.
I want to allow multiple Remote Access VPN configurations that put clients coming from "outside" to "inside-lab" and "inside-clients", with two different profiles and two different IP pools, as the IP addresses for each of the interfaces is different.
How do I do that?
If possible be as explanatory as possible for me to really grasp the concept.
Many thanks
PatHi,
The ASA will view the hosts in its routing table behind the ASA interface which forms the VPN connection with the VPN Client. This is most of the time the interface called "outside".
By default the ASA allows all traffic coming from a VPN connection to bypass the interface ACL of the ASA. The thought process behind this is I guess the fact that the VPN devices/clients have already proven they have right to connect to the network to all traffic is allowed.
The configuration that controls this setting globally on the ASA is
sysopt connection permit-vpn
The above is the default setting of the command and it WONT show up in the CLI format configurations because its a default setting.
If you were to issue the following command
no sysopt connection permit-vpn
Then this would mean that the ASA would require an ACL statement on its VPN terminating interface (outside) to permit the traffic from the VPN Pool to the LAN networks.
Naturally you would have to take into consideration also that if you have existing VPNs and insert the above global command they would also need ACL statements on the "outside" interface ACL or the inbound traffic from the VPN will start to get blocked.
Other option (wihtout touching the above setting) would be to configure VPN Filter ACL that is a separate ACL that is only attached to a certain user or group of users.
I personally prefer the method of using the above global setting and using the "outside" interface ACL to control traffic.
Naturally it still leaves the question of how you are going to configure the Tunnel Groups, Group Policys and Usernames. To be honest, I have gotten a bit distracted from VPN client setups and have forgotten a lot of stuff since I dont work with them on a day to day basis. I mostly handle L2L VPN nowadays among normal firewall configurations.
If I had to suggest something simple at this point it would be this
Configure separate Tunnel Groups
Configure separate VPN Pools for the above Tunnel Groups
Configure separate Group Policys for the above Tunnel Groups
Configure the above mentioned Global setting to limit inbound traffic from VPN
Configure the "outside" interface ACL so that you only permit traffic from a certain VPN Tunnel Group users only to certain LAN networks
Configure the required NAT0 configurations for traffic between these networks
As Marcin said, there are multiple different ways to achieve the same thing as above.
And as I said I have gotten a bit rusty with the VPN Client side on the ASA so I am not sure if at the moment I can even consider all the possible options but surely the simple ones.
PS. The link that Marcin posted seems to point to a Group Policy setting that would let you lock the that VPN connection to use only a certain local Vlan (subinterface) on the ASA and therefore limit traffic from going to networks behind other interfacec
Hope this helps

Remote Access VPN to Site-to-Site VPN
We have a remote access VPN and a site-to-site VPN. Both work fine except that clients of the remote access VPN can not access hosts on the site-to-site VPN.
We are 10.5.5.0
Site-to-Site VPN goes to 10.2.2.0
Remote access clients can access anything on 10.5.5.0 but nothing on 10.2.2.0.
What needs to be done to allow this to happen?Is this ASA/PIX 7?
You need to add the traffic between the lans to the nat exemption and crypto acls on the firewalls.
Headend Firewall
same-security-traffic permit intra-interface
access-list extended permit ip 10.2.2.0 255.255.255.0
Remote Firewall
access-list extended permit ip 10.2.2.0 255.255.255.0
access-list extended permit ip 10.2.2.0 255.255.255.0
Also, if you are split tunnelling you need to add the remote subnet to be tunneled.

Remote access VPN access across LAN-to-LAN VPN
I have two sites (site 1 & site 2) connected by a LAN-to-LAN VPN. At site 1, users connect with a remote access VPN and need to be able to access resources at site 2.
I started out with same-security-traffic intra-interface configured.
Here is the output from both ASAs:

First i would like to Thank you for showing interest in solving my issue...After some research i found that desabling the " IP CEF" will solve the issue...when i desable i was able to communicate success fully with the router lan..But when i desable " IP CEF " Router cpu processer goes to 99% and hangs...
In the output of " sh process cpu" it shows 65% of utilization from "IP INPUT"
so plz give me an alternate solution ....thanks in advance.... -
Can you create a Remote Access VPN connection to tunnel DMZ LAN and Inside Networks simultaneously?
I have a customer that has a ASA 5510 version 8.3 with IPSEC Client Access that includes some of their networks on the Inside interface. The issue they are having is when their mobile users connect with the vpn client (which is using split tunneling), they can no longer access their web server applications that are running in the DMZ. Without the client connected, they access the web servers via the external public IP. Once they are connected via vpn, their default dns server becomes the internal AD DNS server, which resolves the DNS of the web servers to the private DMZ ip address.
Can a Remote Access VPN client connection be allowed to connect to both the DMZ interface and the Inside Interface? I had always only setup RA VPN clients to connect to networks on the Inside Interface.
I tried adding the DMZ network to the Split Tunnel list, but I could not access anything it while connected to vpn using the private IP addresses.Yes, you should be able to access DMZ subnets as well if they are added to the split tunnel ACL. You could check the NAT exemption configuration for the DMZ and also check if the ASA is forwarding the packet through DMZ interface by configuring captures on the DMZ interface.
Share the configuration if you want help with the NAT exemption part. -
Remote Access VPN (ipsec) can ping LAN interface of firewall but not clients on the company network.
The VPN will connect.
I can ping and connect to the ASA 5510 on it's LAN interface.
My problem is that I cannot ping or access anything on the LAN past the firewall. What am I doing wrong?
Here is my config.
Result of the command: "show config"

Cryptochecksum:88a9b69fc3d718c3badfa99db2c7ce4fYeah, I figured out where my problem was.
My IP Local Pool range was the problem.
I was using 10.10.10.0 which conflicted with a point-to-point connection where the serial interfaces were numbered and using 10.10.10.1 and 10.10.10.2.
Traffic would leave the firewall, hit the intended host, go back through my core router, then off to the other network.
I changed my ip local pool to a different range (192.168.100.0) and my problem was solved. -
NAT for remote access VPN clients
Hello,
I have a simple remote access VPN setup on a 2811 router. The remote subnet of the clients connecting have access to the local LAN subnet, but I am wondering if it is possible to somehow NAT those remote access users, so that they can go beyond the local LAN, and through the VPN routers outside connection, giving them access to other resources.
The remote subnet would need to be added to the NAT overload pool that the local LAN is on somehow, but since no interface is created, I am unsure where I would need to put "ip nat inside" if it even needs to be done, or if I am just missing something.
I guess really what I want to do is tunnel all traffic, and have that remote client IP translate to the NAT pool on the router for internet access.
Thanks.Have a look here for solution

Remote access VPN to server from outside and server reach internet on the same time
Dear,
I have problem in my ASA 5515-X , when i make Remote access VPN to servers in inside zone the internet connection disconnected in the servers, or when i have internet in servers, the remote access cant reach servers.
the configuration for server as static NAT for each server, and the connection of VPN is to another public IP but in the same subnet of NAT ip.
server1 : 10.10.10.2 nat to 5.6.7.8
server2: 10.10.10.3 nat to 5.6.7.9
server3: 10.10.10.4 nat to 5.6.7.10
VPN connection to 5.6.7.12
is there any solution for this senario, remote vpn to servers and the same time the servers have internet readability for download updates .. etcHi,
So it seems that the problem is with lacking a NAT0 configuration
You could modify the below configuration to match your networks/IP addresses used. In the below configuration I presume that you have interfaces "inside" and "outside".
object network SERVER-NETWORK
subnet <server network address> <network mask>
object network VPN-POOL
subnet <vpn pool network address> <network mask>
nat (inside,outside) 1 source static SERVER-NETWORK SERVER-NETWORK destination static VPN-POOL VPN-POOL
Just insert the correct address related information and change the "object" and interface names if required.
This configuration will tell the ASA that no NAT will be performed for traffic between the VPN-POOL and SERVER-NETWORK. The NAT configuration is bidirectional. With this configuration the Static NAT configurations will continue to work for the servers Internet traffic and this NAT0 configuration will be applied only to the VPN Client traffic.
Hope this helps :)

Remote Access VPN, no split tunneling, internet access. NAT translation problem
Hi everyone, I'm new to the forum. I have a Cisco ASA 5505 with a confusing (to me) NAT issue.
Single external IP address (outside interface) with multiple static object NAT translations to allow port forwarding to various internal devices. The configuration has been working without issues for the last couple years.
I recently configured a remote access VPN without split tunneling and access to the internet and noticed yesterday that my port forwarding had stopped working.
I reviewed the new NAT rules for the VPN and found the culprit.
I have been reviewing the rules over and over and from everything I can think of, and interpret, I'm not sure how this rule is affecting the port forwarding on the device or how to correct it.
Here are the NAT rules I have in place: (The "inactive" rule is the culprit. As soon as I enable this rule, the port forwarding hits a wall)
nat (inside,outside) source static any any destination static VPN_Subnet VPN_Subnet no-proxy-arp route-lookup
nat (outside,outside) source static VPN_Subnet VPN_Subnet destination static VPN_Subnet VPN_Subnet no-proxy-arp route-lookup
nat (outside,outside) source dynamic VPN_Subnet interface inactive
object network obj_any
nat (inside,outside) dynamic interface
object network XXX_HTTP
nat (inside,outside) static interface service tcp www www
access-group outside_access_in in interface outside
route outside 0.0.0.0 0.0.0.0 xxx.xxx.xxx.xxx 1
Any help would be appreciated.Try by changing the nat rule to nat (outside,outside) after-auto source dynamic VPN_Subnet interface
With Regards,

Site to Site and Remote Access VPN
Hi All,
Is it possible to configure Site to Site and Remote Access VPN on same interface of Cisco ASA 5505 ?
Regards
Abhishek
This topic first appeared in the Spiceworks CommunityA document exists where PIX/ASA maintains LAN-ti-LAN IPsec tunnel at two end points and there is overlapping networks at ther inside interface of both the asa. Probably, the basic configuration for both asa and IOS routers are nat config. So, this particular document might be useful for your requirement

Remote Access VPN Clients Cannot Access inside LAN
I have been asked to set up remote access VPN on an ASA 5505 that I previously had no invlovement with. I have set it up the VPN using the wizard, they way I normally do, but the clients have no access to anything in the inside subnet, not even the inside interface IP address of the ASA. Thay can ping each other. The remote access policy below that I am working on is labeled VPNPHONE, address pool 172.16.20.1-10. I do not need split tunneling to be enabled. The active WAN interface is the one labeled outside_cable.

: endHi,
You have your "group-policy" set so that you have excluding some networks from being tunneled.
In this access-list named Local_LAN_Access you specify "0.0.0.0"
Doesnt this mean you are excluding all networks from being tunneled? In other words no traffic goes to your tunnel.
This access-list should only contain your local LAN network from where you are connecting with the VPN Client. If you dont need to access anything on your local LAN while having the VPN on, you don't even need this setting on. You could just tunnel all traffic instead of excluding some networks.

Remote Access VPN - Unable to Access LAN / Inside Network
Hi,
I am facing a problem with Cisco ASA remote access VPN, the remote client is connected to VPN and receiving IP address but the client is not able to ping or telnet any internal network.
I have attached running configuration for your reference. Please let me know I miss any configuartion.
FW : ASA5510
Version : 8.0
Note : Site to Site VPN is working without any issues
Thanks
JamalHi,
Very nice network diagram
Are you saying that originally the VPN Client user is behind the Jeddah ASA?
If this is true wouldnt it be wiser to just use the already existing L2L VPN between these sites?
In real situation I think the VPN Client would only be needed when you are outside either Head Quarter or Jeddah Network. And since you tested it infront of the ASA and it worked there shouldnt be any problem.
Now to the reason why the VPN Client isnt working from behind the Jeddah ASA.
Can you check that the following configuration is found on the Jeddah ASA (Depending on the software level of the ASA the format of the command might change. I'm not 100% sure)
isakmp nat-traversal To enable NAT traversal globally, check that ISAKMP is enabled (you can enable it with the isakmp enable command) in global configuration mode and then use the isakmp nat-traversal command. If you have enabled NAT traversal, you can disable it with the no form of this command.
isakmp nat-traversal natkeepalive
no isakmp nat-traversal natkeepalive
Syntax Description
natkeepalive
Sets the NAT keep alive interval, from 10 to 3600 seconds. The default is 20 seconds.
Defaults
By default, NAT traversal (isakmp nat-traversal) is disabled.
Command Modes
The following table shows the modes in which you can enter the command:

Preexisting
This command was preexisting.
7.2(1)
This command was deprecated. The crypto isakmp nat-traversal command replaces it.
Usage Guidelines Network Address Translation (NAT), including Port Address Translation (PAT), is used in many networks where IPSec is also used, but there are a number of incompatibilities that prevent IPSec packets from successfully traversing NAT devices. NAT traversal enables ESP packets to pass through one or more NAT devices.
The security appliance supports NAT traversal as described by Version 2 and Version 3 of the IETF "UDP Encapsulation of IPsec Packets" draft, available at http://www.ietf.org/html.charters/ipsec-charter.html, and NAT traversal is supported for both dynamic and static crypto maps.
This command enables NAT-T globally on the security appliance. To disable in a crypto-map entry, use the crypto map set nat-t-disable command.
Examples
The following example, entered in global configuration mode, enables ISAKMP and then enables NAT traversal with an interval of 30 seconds:
hostname(config)# isakmp enable
hostname(config)# isakmp nat-traversal 30

Remote access VPN-unable to connect inside-URGENT
Hi,
I have configured Remote access VPN in cisco ASA 5520.Whenever I am trying to connect from outside it's connecting fine.It aslo getting IP from pool but prob is i am unable to connect/ping inside nw.
Pls help me...how to resolve this issue.I had the same problem on an IOS router (871). My solution was one of two things. I downloaded the most up-to-date version of the VPN client (5.0.02.90) as opposed to the version I had or it was a software firewall (Norton 360). I have two different computers. One works just fine...the other connects but no traffic passes through. Here is what I have:
Computer 1 (working)- VPN Client v5.0.02.0090 and Network Associates Enterprise VirusScan.
Computer 2 (not working) - VPN Client v5.0.00.0340 and Norton 360.
I highly doubt it is the VPN Client, but sometimes you never know. Check your software firewall and try disabling it. Let me know how this works. -
I have problem for authenticar a remote access VPN with ACS 5.0, not work.
When I try with ACS 4.1, the authentication work fine.
I hope someone can help me.
Regards.I have the same problem. I'm using ASA v8.21 and ACS v5.0.0.21, which I'm using as tacacs and radius server. I have no problem with accessing devices via tacacs (except that changing pass with first login doesn't work). The problem is with VPN authentication. I tested radius with Radlogin and PAP is working fine, CHAP goes in timeout, but as I know ACS 5.0 doesn't suport CHAP.
Here are some logs from ASA:
