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.

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 client gets connected fails on hosts in LAN
Hi,
VPN client gets connected fine, I have a inter VLAN routing happening on the switch in the LAN so all the LAN hosts have gateway IP on the switch, I have the defult route pointing to ASA inside interface on the switch, the switch I can reach after Remote Access VPN is connected how ever I cannot ping/connect to other hosts in the LAN and if I make the gateway point to the ASA then that host is accessible, any suggestions? I really want to have gateway to be the Switch as I have other networks reachable through the Switch (Intranet routing)Hi Mashal,
Thanks for your time,

We don't need route print on the PC for now as I can explain what is happening I can get complete access to the 192.168.2.0/24 (VLAN 1000) but for 192.9.200.0/24 (VLAN 4000) above from the switch I can only ping IP's on the switches/pair but cannot have any tcp connections, which explains the default route being pointed on the switch is on VLAN 1000, now my issue is How do I get access to VLAN 4000 as you can see these two are on different Interfaces/zones on the ASA and please note with default gateway pointing to ASA I will have access to both the VLAN's it is only when I move the gateway pointing to Switch I loose tcp connections to one VLAN depending on the default route on the being pointing to on the switch.
So we are left to do with how to on the switch with default route. -

Here is some capture done on the inside interface which may help too, I tried pointing the gateway to inside interface on the target device but I think this was a switch without ip route available on it I believe that is still sending packet back to Cisco inside interface

Any help or pointers greatly appreciated, I am doing this config after a long gap on Cisco last time I was working it was all PIX so just need some expert eyes to let me know if I am missing something.
And Yes I do not have a Host in Inside network to test against, all I have is a switch which cannot route and ip default gateway is not helping too...Hi,
The first thing you should do to avoid problems is to change the VPN Pool to something else than the current LAN network as they are not really directly connected in the same network segment.
You could try the following changes
tunnel-group RAVPN general-attributes
no address-pool RAVPN
no ip local pool RAVPN 192.168.200.1-192.168.200.254 mask 255.255.255.0
ip local pool RAVPN 192.168.201.1-192.168.201.254 mask 255.255.255.0
tunnel-group RAVPN general-attributes
address-pool RAVPN
no nat (any,inside) source static NETWORK_OBJ_192.168.200.0_24 NETWORK_OBJ_192.168.200.0_24 destination static NETWORK_OBJ_192.9.200.0_24 NETWORK_OBJ_192.9.200.0_24
In the above you first remove the VPN Pool from the "tunnel-group" and then remove and recreate the VPN Pool with another network and then insert it back to the same "tunnel-group". Nex you remove the current NAT configuration.
object network LAN
subnet 192.168.200.0 255.255.255.0
object network VPN-POOL
subnet 192.168.201.0 255.255.255.0
nat (inside,outside) 1 source static LAN LAN destination static VPN-POOL VPN-POOL
The above NAT configurations adds the correct NAT0 configuration for the changed VPN Pool. It also inserts the NAT rule to the very top before the Dynamic PAT rule you currently have. It is also one of the problems with the configurations as it will override your current NAT configurations.
You have your Dynamic PAT rule at the very top of your NAT rules currently which is not a good idea. If you wish to change it to something else that wont override the other NAT configurations in the future you can do the following change.
no nat (inside,outside) source dynamic any interface
nat (inside,outside) after-auto source dynamic any interface
NOTICE! Changing the above Dynamic PAT configuration will temporarily terminate all connections for users from the LAN as you reconfigure the Dynamic PAT rule. So if you do this change make sure that its ok to cause still small cut in the current connections of internal users
Hope this helps
Let me know if it works for you

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 :)

Hi all, I have been having issues with my remote access vpn, I can connect but cannot ping anywhere, I have enabled ipsec over nat-t, but still does not work, I noticed that when I did an ipconfig on my machine, I get the ip address assigned by my asa, 10.120.50.2 /32
but the default gateway is showing as 10.112.50.3, is this correct, I thought it should be the same as the interface address ?Hi Carl,
Can you make sure you have the following in your config:
isakmp nat-traversal
Can you also ensure your internal network has routing in place to cover your VPN client pool. -
Remote Access VPN Users with CX Active Authentication.
I have ASA 5515 with CX for webfiltering , also have enabled remote access vpn . All my inside users are able to get active and passive authentication correctly . But for remote access VPN users , they are redirected to ASA external ip and CX authentication port 9000 but a blank page comes in and there is no prompt for authentication. I wasnt doing split tunneling , but now i have excluded ASA WAN ip from the tunnel and still have the same issue.
The CX version we have is 9.3.1.1Have you excluded the VPN traffic from being NATed when traffic is going between clients?
Please post a full sanitised configuration of the router so we can check it for configuration issues.
Please remember to select a correct answer and rate helpful posts -
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. -
Hii frnds,
here is the configuration in my router C1841..for the cisco ipsec remote access vpn..i was able to establish a vpn session properly...but there after i can only reach up to the inside interfaces of the router..but not to the lan devices...
Below is the out put from the router

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.... -
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 connecting but not passing traffic
I have a remote access VPN configured on a device here. I'm able to connect a device and it assigns me an IP address out of the pool, and injects the routes to its local network, but I'm not able to pass any traffic through the VPN and none of the IPSec SA counters increment for the dial-in connection. I've compared the config here to the samples from documentation and I don't know what I'm missing. Config is below.

ASA Remote Access VPN: internal LAN cannot connect to connected VPN clients
Hi community,
I configured IPSec remote Access VPN in ASA, and remote client use Cisco VPN client to connect to the HQ. The VPN is working now, VPN clients can connect to Servers inside and IT's subnet, but from my PC or Servers inside LAN cannot ping or initial a RDP to connected VPN clients. Below is my configuration:
object-group network RemoteVPN_LocalNet
network-object 172.29.168.0 255.255.255.0
network-object 172.29.169.0 255.255.255.0

default-group-policy Split_Tunnel_Policy
I don't know what I miss in order to have internal LANs initial connection to connected vpn clients. Please guide me.
Thanks in advanced.Hi tranminhc,
Step 1: Create an object.
object network vpn_clients
subnet 10.88.61.0 mask 255.255.255.0
Step 2: Create a standard ACL.
access-list my-split standard permit ip object RemoteVPN_LocalNet
Step 3: Remove this line, because I am not sure what "Allow_Go_Internet" included for nat-exemption.
no nat (inside,outside) source static Allow_Go_Internet Allow_Go_Internet destination static remotevpnpool remotevpnpool
Step 4: Create new nat exemption.
nat (inside,outside) source static RemoteVPN_LocalNet RemoteVPN_LocalNet destination static vpn_clients vpn_clients
Step 5: Apply ACL on the tunnel.
group-policy Split_Tunnel_Policy attributes
split-tunnel-policy tunnelspecified
split-tunnel-network-list value my-split
Step 6:
I assume you have a default route on your inside L3 switch point back to ASA's inside address. If you don't have one.
Please add a default or add static route as shown below.
route 10.88.61.0 mask 255.255.255.0 xxx.xxx.xxx.xxx
xxx.xxx.xxx.xxx = equal to ASA's inside interface address.
Hope this helps.
Thanks

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 )

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
MaheshHi 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_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 users unable to communicate with each other
Hi,
We have configured Remote Access VPN on Cisco IOS router. Users are able to access the inside resources but cant communicate to each other. Any suggestions on the issue?
Regards
SaifHave you excluded the VPN traffic from being NATed when traffic is going between clients?
Please post a full sanitised configuration of the router so we can check it for configuration issues.

Remote Access VPN - add new internal IP
Hi
I have a existing Cisco VPN client configuration into ASA 5510 for remote access.
Group name : ISETANLOT10
Group password : xxxx
IP pool : lot10ippool, 172.27.17.240 - 172.27.17.245
enycrption : 3DES
authentication : SHA
the connection was successful and i was able to ping to the internal server of 172.47.1.10.
Now there is request for the same VPN remote access to be able to ping access a new server inside LAN, 172.57.1.10 & 172.57.1.20
But with the same VPN access, i was unable to ping both new IP.
How can i add in the both IP to be able to ping using the same remote access VPN config?
I attached below existing config (edited version)

!=====The remote access VPN should allow the connection but I am guessing your ASA doesn't know how to route to the two new destinations.
You have a name and static route for the working server at 172.47.1.10:
name 172.47.1.10 NarayaServer description Naraya Server
route inside NarayaServer 255.255.255.255 172.27.17.100 1
..but no equivalent for the two new hosts. As a result, any traffic from the ASA destined for them will attempt to use the default route (via the outside interface).
If you add:
route inside 172.57.1.10 255.255.255.255 172.27.17.100
route inside 172.57.1.20 255.255.255.255 172.27.17.100
(assuming that's your correct gateway), it should work.
