ASDM conc (ASA) VPN access
I have the script like this:
an ASA, which is the FW, TR making static NAT from the public to the private IP and private IP address add is add conc (another ASA) VPN. I am accessing these devices via the VPN client and I get the address IP of VPN pool set on VPN conc. VPN conc. is in a DMZ VLAN, but it also has connection to the local network segment. Purposes of mgmt, I connect to this VPN through SSH conc via a switch in the local network segment. To use the http access, I have to be on one of the servers that are in the local network segment. Since then, when I set up the VPN connection, I'm sure VPN conc., what can do to access http directly from my PC?
This sets up on the conc VPN:
management-access insideAfter that you should be able to use ASDM over the VPN tunnel, by connecting to its inside ip address.

Hello:
I have configured ASA 5505 to acept Cisco VPN Clients on IP-SEC and access internal subnet of tuneling (added a rule exempt NAT too) and the VPN Clients can connect and work without problems.
But no internal network or the ASA I can ping or conect to the VPN Clients.
My configuration:
Internal network: 172.26.1.0 255.255.255.0
The VPN Clients network 172.26.2.0 255.255.255.0
Can you help me?
Here is my configuration:

Raul,
I don't see to apply ACLs inside the interface or as vpn-filter that will prevent the PING of the SAA within the intellectual property to the VPN client.
Are you sure that the VPN client does not have the Windows Firewall on or antivirus software that prevents to respond to PING?
Federico.

Hi, I recently bought an ASA 5520 to use as a VPN gateway for several tunnells site to site VPN. I've upgraded to version 8.3, and set up a lab environment. I implemented a simple VPN with a rule of intellectual property general permit to stert with and everything works fine. I'm having trouble tightenign access now, if I change the access on the SAA for ICMP I can ping both directions, if I add tcp I can telnet from a computer at the other end of the VPN, but if I change the tcp protocol to telnet, I can't connect. the other end on the VPN is a cisco 2620XM and I match the lists of access for each of the changes. I also do not understand the meaning of the ASA access list, it seems that if I want to allow the remote tcp host behind the ASA access I have the host behind the ASA as the source, it appears backward? Anyone can shed some light on this? very much appreciated.
Yes, you are supposed to only configure 'IP' to your ACL (ACL applied to your crypto card) crypto and crypto ACL supposed to mirror image on each peer, so when you change to specific TCP/UDP ports, is not mirror image of the other side/peer more.
I thought that you use ACL applied to "vpn-filter".
But in the previous post, actually configure you ACL on each interface.
The above is 3 different ACL you have applied differently (crypto ACL--> apply to the card crypto, vpn ACL--> apply to vpn-filter and your normal ACL interface).

ASA 5505: VPN access to different subnets
Hi All-
I'm trying to understand how to configure our ASA so that remote users can have VPN access to two different subnets (Office LAN and LAN phone). Currently I have 3 VLAN configuration - VLAN 1 (inside), VLAN 2 (outside), VLAN 13 (phone LAN). Essentially, remote users must be able to access their PC (192.168.1.0/24) and also have access to the office phone system (192.168.254.0/24). Is it still possible? Here are the configurations on our ASA,
Thanks in advance:

Hello
Loss of connectivity to the LAN is not really supposed all remove this command UNLESS your network is using another device as their gateway to the Internet. In this case configuration dynamic PAT or political dynamics PAT (as you) would make sense because the LAN hosts would see your VPN connection from the same directly connected network users and would be know to traffic before the ASA rather than their default gateway.
So is this just for VPN usage and NOT the gateway on the LAN?
If it is just the VPN device I'd adding this
global interface (phones) 10
He would do the same translation for 'phones' as he does on 'inside' (of course with different PAT IP)

Unable to connect to other remote access (ASA) VPN clients
Hello
I have a cisco ASA 5510 appliance configured with remote VPN access
I can connect all hosts on the INSIDE and DMZ network, but not able to access other clients connected to the same VPN.
For example, if I have 2 clients connected to the VPN, customer and CustomerB, with a pool of vpn IP addresses such as 10.40.170.160 and 10.40.170.161 respectively, these two clients are not able to communicate with each other.
Any help is welcome.
Thanks in advance.
Hello
I'm a little rusty on the old format NAT, but would be what I would personally try to configure NAT0 on the 'outer' interface.
It seems to me that you currently have dynamic PAT configured for the VPN users you have this
NAT (outside) 1 10.40.170.0 255.255.255.0
If your traffic is probably corresponding to it.
The only thing I can think of at the moment would be to configure
Note of VPN-CLIENT-NAT0-access-list NAT0 for traffic between VPN Clients
list of access VPN-CLIENT-NAT0 permit ip 10.40.170.0 255.255.255.0 10.40.170.0 255.255.255.0
NAT (outside) 0-list of access VPN-CLIENT-NAT0
I don't know if it works. I did not really have to configure it on any ASAs running older software. There was some similar questions here on the forums for the new format.

We have configured the VPN tunnel from site of offshore to the location of the customer using ASA5510 and access to RDP to the location of the customer. Also been configured remote VPN access in offshore location. But using the remote VPN client, we are able to get the RDP of officeshore location but not able to access to the location of the RDP client. Are there any additional changes required?
Thank you
Hi Salsrinivas,
so to summarize:
the VPN client connects to the ASA offshore
the VPN client can successfully RDP on a server at the offshore location
the VPN client cannot NOT RDP on a server at the location of the customer
offshore and the location of the customer are connected by a tunnel L2L
(and between the 2 sites RDP works very well)
is that correct?
Things to check:
-the vpn in the ACL crypto pool?
-you're exemption nat for traffic between the vpn pool and 'customer' LAN? is the exemption outside (vpn clients are coming from the outside)?
-you have "same-security-traffic permitted intra-interface" enabled (traffic will appear outside and go back outside)?
If you need help more could you put a config (sterilized) Please?

Remote access ASA, VPN and NAT
Hello
I try to get access to remote VPN work using a Cisco VPN client and ASA with no split tunneling. The VPN works a little, I can access devices inside when I connect, but I can't access the Internet. I don't see any errors in the log ASA except these:
1 Jul 04:59:15 % ASA-3-305006 gatekeeper: failed to create translation portmap for udp src outside:192.168.47.200/137 dst outside:192.168.47.255/137
1 Jul 04:59:15 % ASA-3-305006 gatekeeper: failed to create translation portmap for udp src outside:192.168.47.200/54918 dst outsidexx.xxx.xxx.xxx/53There is only one address public IP that is assigned to the external interface of DHCP. The Interior is 192.168.1.0/24 network which is PAT'ed to the external interface and the VPN network is 192.168.47.X.
I think my problem is that the net.47 is not NAT'ed out properly and I don't know how to put in place exactly. I can't understand how this is supposed to work since the net VPN technically provenance from the outside already.
Here are all the relevant config:
list of vpn access extended permits all ip 192.168.47.0 255.255.255.0
Within 1500 MTU
Outside 1500 MTU
IP local pool vpnpool 192.168.47.200 - 192.168.47.220 mask 255.255.255.0
IP verify reverse path to the outside interface

ICMP allow all outside
Global interface (2 inside)
Global 1 interface (outside)
NAT (inside) 0-list of access vpn
NAT (inside) 1 0.0.0.0 0.0.0.0
NAT (outside) 2 192.168.47.0 255.255.255.0 outside
static (inside, outside) tcp 3074 XBOX360 3074 netmask 255.255.255.255 interface
static (inside, outside) udp 3074 XBOX360 3074 netmask 255.255.255.255 interface
public static (inside, outside) udp interface 88 88 XBOX360 netmask 255.255.255.255
public static tcp (indoor, outdoor) https someids netmask 255.255.255.255 https interfaceI can post more of the configuration if necessary.
Change ' nat (outside) 2 192.168.47.0 255.255.255.0 apart ' "NAT (2-list of vpn access outdoors outside)" gives these:
1 Jul 06:18:35 % gatekeeper ASA-3-305005: no group of translation not found for udp src outside:192.168.47.200/56003 dst outside:66.174.95.44/53
So, how I do right NAT VPN traffic so it can access the Internet?
A few things that needs to be changed:
(1) NAT exemption what ACL must be modified to be more specific while the traffic between the internal subnets and subnet pool vpn is not coordinated. NAT exemption takes precedence over all other statements of NAT, so your internet traffic from the vpn does not work.
This ACL:
list of vpn access extended permits all ip 192.168.47.0 255.255.255.0
Should be changed to:
extensive list of access vpn ip 192.168.47.0 255.255.255.0 allow
(2) you don't need statement "overall (inside) 2. Here's what to be configured:
no nat (outside) 2 192.168.47.0 255.255.255.0 outside
no global interface (2 inside)
NAT (outside) 1 192.168.47.0 255.255.255.0
(3) and finally, you must activate the following allow traffic back on the external interface:
permit same-security-traffic intra-interface
And don't forget to clear xlate after the changes described above and connect to your VPN.
Hope that helps.

Wacky VPN access problem of ASA
Hi people,
I am currenty a situation, and I am in real need of advice...
The situation is that, if ASA helps my remote branches to access my home network and its allowing people to visit Internet inside, its not allowing the remote VPN client VPN access... R V to aid VPN client version of Cisco 4.6...
See a presentation of basic network that illustrates our network and configuration of the ASA...
Advice to solve this problem will be greatly appreciated...
Kind regards

asa himself through site to site vpn access server
Hello
I have problem with access to the servers through site to site vpn to ASA that makes this vpn site-to-site and Clientless VPN enablerd.
Reason why I need it / what I do:
ASA 5510 enabled Clientless VPN and on this Portal allows users to access internal servers through bookmars URL. We use it when someone wouldn't access IPSec VPN or in an internet café. If this user connects to clientless vpn and click on the bookmark to access for example mail server. But there is problem, asa cannot access this server through VPN site-to-site.
Network:
Here's a quick design of my network.
I don't have server access to the problem in the VLAN 159 of VLAN 10, or 100. But I need to be able to access the server in Vlan 159 of ASA 5510, who owns the IP 192.168.1.4.
I have this subnet ASA owned by FRONT-NAT object in the same place that VLAN 10 to 100 are and vpn Site-to-Site profile.
What I makeover or how can I solve it?
Thank you
Clientless VPN when accessing internal servers, it will use the closest to the source of the connection interface and if you connect to via clientless SSL VPN ASA5510 and need access ASA5505 LAN via the site to site VPN, the interface closest to the ASA5510 to ASA5505 LAN is ASA5510 outside interface, therefore, the vpn of site-to-site crypto ACL must match on ASA5510 outside the ip address of the interface.
Here's what you need on each ASA:
ASA5510:
permit same-security-traffic intra-interface
ip 192.168.159.0 external interface allowed access list 255.255.255.0
ASA5505:
ip 192.168.159.0 access list allow 255.255.255.0 host
In addition, also need to add the same ACL for access-list of exemptions on ASA5505 NAT:
ip 192.168.159.0 access list allow 255.255.255.0 host
Hope that helps.

VPN access to the not directly connected networks
Hello
I have a 5510 which is used for Client VPN access and there is something simple that I can't work.
The VPN part works very well with AAA on a CBS.
But what does not is access to networks that are not directly connected to the inside interface.
That is to say the VPN users can connect to the network within the Interface (say 192.168.0.0/24) but not a 10.0.0.0/8 network which is connected through 192.168.0.1 router.
I have the static routes in Routing and firewall all showing the way back to the firewall on all the other networks, but I don't get more far the 192.168.0.1 router...
I use split tunneling and pass all of the private over the VPN - internet networks is used through the own local access to clients.
Can someone help me out here?
Thank you.
Fraser
PS: have the same type of access on a 7206VXR and soft, everything can be consulted and which is necessary - but I would like to move this service to the ASA.
Fraser
I don't understand the ASDM parts as you suggest. The code would be great.
I would also recommend control ACL applied to the inside interface (if any) that it allows traffic as
inside_access_in list of permitted access 10.0.0.0 255.0.0.0 vpnsubnet vpnnetmask
If still no joy, attach your config sanitized, would be useful for me to diagnose.

VPN access to several local networks virtual asa8.3
you are looking for assistance. This one goes batty.
I have ASA 5510 8.3 running
It serves as a router, firewall and vpn.
the underlying network works fine.
When I connect via VPN, I can only access my reseau.41 and not on the reseau.42. When I try to do a ping.42 I get this error:
5 October 18, 2010 00:33:13 192.168.42.11 3389 rules asymmetrical NAT matched for flows forward and backward; Connection for tcp src Outside:192.168.43.200/2916 dst servers:192.168.42.11/3389 refused due to path failure reverse that of NAT
If I flip through these rules in order to config then I can acceder.42 through the vpn but pas.41
NAT (servers, all) static source any any destination static obj-vpnpool obj-vpnpool
NAT (iscsimgmt, any) static source any any destination static obj-vpnpool obj-vpnpoolI'm confused because it's all a new config and I used the wizard in asdm and couldn't access squat (perhaps he does not know how to manage the VLAN)?
the ASA may well ping of all networks.
devices on the network can ping each other fine
just via ipsec vpn, I can't access both networks.
thoughts?
Please configure a more specific NAT statements as follows:
object obj-iscsimgmt network
192.168.42.0 subnet 255.255.255.0NAT (servers, Outside) source static obj-servers obj-servers destination static obj-vpnpool obj-vpnpool
NAT (iscsimgmt, Outside) source static obj-iscsimgmt obj-iscsimgmt destination static obj-vpnpool obj-vpnpoolAnd pls Remove the following:
NAT (servers, all) static source any any destination static obj-vpnpool obj-vpnpool
NAT (iscsimgmt, any) static source any any destination static obj-vpnpool obj-vpnpoolThen "clear xlate" after the changes described above.
Hope that helps.

Hello
I have a question concerning the VPN, is it possible to configure the two IPsec VPN site-to-site and remote access vpn on the same ASA and working at the same time, does require one or two different public ip addresses?
I have cisco ASA 5540 - version 9.1
Best regards
Hello
Yes, you can with 1 single public ip address. You need to activate the same-security-traffic allow intra-interface functionality to allow a customer vpn site-to-site vpn access if you need.
Take a look at the Cisco documentation;

Hello
We have an asa 5585 on the network and it is configured for remote access VPN with RSA.
When a VPN user connects to their VPN, he is invited for a PIN followed their secure ID token code.
We want to simplify our VPN configuration if we starting from a perspective of support and management, users use a hard chips. Currently, many lose their chips or have a connection problem, so I would like to know what simple VPN solution, we have in place.
Then is it possible on the ASA when I check my VPN traffic to determine what users are using the VPN for, since the purpose is if they only use it for email, so we can advise them to use webmail rather and can disable VPN access.
With respect to the VPN, I see only two options; you either empty tokens to make life easier or you keep them and put up with it.

Assign the static IP address by ISE, ASA VPN clients
We will integrate the remote access ASA VPN service with a new 1.2 ISE.
Authentication is performed in Active directory. After authentication, can address assigned to a specific user of VPN by ISE IP?
This means that the same VPN user will always get the same IP address. Thank you.
Daniel,
You can override the IETF-RADIUS-Framed-IP-Address in the authorization policy.
However if I may make a suggestion:
Unless you have only a handful of users to do so, it may be appropriate to assign the address of ISE pool or perform the mapping of LDAP attributes on ASA itself.
In the latter case, the IP addresses are kept on the server as LDAP attributes and ASA will map the IP address. You don't want to keep address IP DB in several places.
