Remote RDP client VPN access on ASA 5510
Hello.
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?

Client VPN access to VLAN native only
I have a router 2811 (config below) with VPN set up. I can connect through the VPN devices and access on the VLAN native but I can't access the 10.77.5.0 (VLAN 5) network (I do not access the 10.77.10.0 - network VLAN 10). This question has been plagueing me for quite a while. I think it's a NAT device or ACL problem, but if someone could help me I would be grateful. Client VPN IP pool is 192.168.77.1 - 192.168.77.10. Thanks for the research!

If you want to say, that after the way nat rules which I have proposed, you lost the connection to the VLAN native, so yes, it's because the subnet VLANs native has not been included in this acl with Deny statement. So that the ACL should look like this:
NAT extended IP access list
deny ip 10.77.5.0 0.0.0.255 192.168.77.0 0.0.0.255
deny ip 10.77.1.0 0.0.0.255 192.168.77.0 0.0.0.255 //This is not respected
allow an ip
In addition, if you want to go throug the other tunnel inside the subnet not listed above, then you should include that subnet to the NAT exemption rule with Deny statement.

AnyConnect VPN license on ASA 5510
Hello
We have ASA 5510 IPS with basic license. We must now Anyconnect support for more than 2 users.
Anyconnect (tunnel mode) but essentially Anyconnect license enough? Do need me a license for SSL VPN peers?
What about Anyconnect without customer, I see that I need a premium license?
This one is pretty ASA5510-SSL50-K9? It's really expensive compared the Anyconnect Essentials.
Here is my worm out sh:
The devices allowed for this platform:
The maximum physical Interfaces: unlimited
VLAN maximum: 50
Internal hosts: unlimited
Failover: disabled
VPN - A: enabled
VPN-3DES-AES: enabled
Security contexts: 0
GTP/GPRS: disabled
SSL VPN peers: 2
The VPN peers total: 250
Sharing license: disabled
AnyConnect for Mobile: disabled
AnyConnect Cisco VPN phone: disabled
AnyConnect Essentials: disabled
Assessment of Advanced endpoint: disabled
Proxy sessions for the UC phone: 2
Total number of Sessions of Proxy UC: 2
Botnet traffic filter: disabledThis platform includes a basic license.
Yes, AnyConnect Premium includes all the SSL features (including the complete tunnel mode AnyConnect - which is what sustains essential AnyConnect).
So if you buy the 50 user for AnyConnect Premium license, you can have up to 50 SSL VPN connections, if they are the combination of all without customer, or combination of tunnel without customer and full, or just full tunnel. All with a maximum of 50 simultaneous SSL tunnels.

Client VPN und Cisco asa 5505 tunnel work but no traffic
Hi all
I am new to this forum and Don t have a lot of experience with Cisco, so I hope I can get help from specialists.
I have the following problem:
I installed und konfigured ASA 5505 for use with vpn client. I would like to access the local network from outside through vpn.
To test, I installed ASA 5505 with ADSL (pppoe) and tried to give access to the internal network.
Of course whenever I have recive the supplier's different IP address, but it didn't is not a problem reconfigure in the vpn client.
After the connection is established (vpn tunnel work) I can see my external network packets. But I Don t have any connection to the internal network.
I erased my setup yesterday and tried to reconfigure ASA again. I didn t tested yesterday, because it was too late. And I know that I Don t have the authorization rule at present by the ACL. But I think I'm having the same problem again. (tunnel but no traffic).
What I did wrong. Could someone let me know what I have to do today.
With hope for your help Dimitri.

Hello
Normally, you want a static public IP address on the ASA to allow it to receive connections from VPN clients (avoid to change the IP address all the time).
If you connect via VPN, check the following:
1. the tunnel is established:
HS cry isa his
Must say QM_IDLE or MM_ACTIVE
2 traffic is flowing (encrypted/decrypted):
HS cry ips its
3. Enter the command:
management-access inside
And check if you can PING the inside ASA VPN client IP.
4. check that the default gateway for the LAN internal ASA within intellectual property (or there is a road to the ASA to send traffic to the VPN clients).

Help with a VPN tunnel between ASA 5510 and Juniper SSG20
Hello
We have a customer wanting to configure a VPN Site to Site tunnel between a new purchased 5510 of ASA located in his direction with its Juniper SSG20 Office, located in the main office. We contacted HP and they send us a Cisco professional to do the job.
After 2 days from 16:00 to 22:00 and error and countless hours of research online and nunerous calls, we are still unable to get traffic from the network of agencies to enter the tunnel.
Main branch
1.1.1.2 1.1.1.1
----- -----------
192.168.8.0/24 | ASA|-----------------------------------| Juniper | 192.168.1.0/24
----- -----------
192.168.8.254 192.168.1.254According to Cisco professionals, the tunnel is now in place but no traffic through. We are unable to ping anything on the network on the other side (192.168.1.0/24). We receive timeout ping all the time. The Cisco professional told us it's a routing or NAT problem and he's working on a solution!
Through research, I came across a post on Experts-Exchange (here) [the 1st comment on the original post] which States "...". that both sides of the VPN must have a different class of LAN for the VPN to work... " Would that be our problem?
It has become a critical issue to the point that he had to replace the Cisco ASA with a temporary Juniper SSG5 on another subnet (192.168.7.0/24) to get the tunnel upward and through traffic until the ASA VPN issue is resolved and I didn't need to say that the client is killing us!
Help is very appreciated.
Thank you
1. Yes, ping package from the interface of the ASA is considered valuable traffic to the LAN of Juniper.
SAA, need you traffic from the interface source ASA's private, because interesting to determine by crypto ACL MYLIST traffic between 192.168.8.0/24 and 192.168.1.0/24.
You will also need to add the following configuration to be able to get the ping of the interface of the ASA:
management-private access
To initiate the ping of the private interface ASA:
ping 192.168.1.254 private
2. the default time before the next generation of new key is normally 28800 seconds, and if there is no interesting traffic flowing between 2 subnets, he'll tear the VPN tunnel down. As soon as there is interesting traffic, the VPN tunnel will be built automatically into the next generation of new key. However, if there is traffic before generating a new key, the new tunnel will be established, and VPN tunnel will remain standing and continue encrypt and decrypt traffic.
Currently, your configuration has been defined with ITS lifetime of 3600 seconds GOLD / 4608000 kilobytes of traffic before the next generate a new key (it will be either 3600 seconds, or 4608000 kilobytes period expires first). You can certainly change it by default to 28800 seconds without configuring kilobytes. SA life is negotiated between the ASA and Juniper, and whatever is the lowest value will be used.
Hope that helps.

VPN site-to-site between two PIX 501 with Client VPN access
Site A and site B are connected with VPN Site to Site between two PIX 501.
Also, site A is configured for remote access VPN client. If a remote client connects to Site A, it can only get access to the LAN of Site A, it cannot access anything whatsoever behind PIX on Site B.
How is that possible for a VPN client connected to Site A to Site B?
Thank you very much.
Alex
Bad and worse news:
Bad: Not running the 7.0 series PIX cannot route traffic on the same interface, the traffic is recived. Version 7.0 solves this ipsec traffic.
Even worse: PIX 501 can not be upgraded to 7.0...
A couple of things to think about would be the upgrade to hardware that can run the new IOS or allowing a VPN R.A. on site B.
HTH Please assess whether this is the case.
Thank you

Client VPN access router to the Internet through the same router! How?
Hi all
I already setup VPN users connect to our router 1841 and corporate network. Use Cisco VPN Client and connection ends on the interface Dialer1 in 1841. This interface is also our ADSL Internet connection.
I need the VPN users out to the Internet via this VPN connection (it is through this Dialer1), rather than use the split tunneling and Internet browsing from their Local Internet service providers.
Of course, this Dialer1 is also 'nat outside' and FastEthernet is LAN and "nat inside '.
So I'll need NAT these VPN-pool addresses to address IP Dialer1. But what would be 'nat inside' in this case...
Can anyone help?
a loopback interface must be configured to "nat inside '.
for example
Loopback int 1
IP 1.1.1.1 255.255.255.0
No tap
IP nat inside
access-list 199 refuse ip<1841 private="" net=""><1841 private="" net="" mask="">
access-list 199 ip allow a
allowed policy-road route map 10
corresponds to the IP 199
set ip next-hop 1.1.1.2
interface Dialer0

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

SRP526W to transmit or provide VPN access to clients
Hello
We have a SRP526W here, which replaced a cheap, simple router. Now, we would like to set up VPN access for outside clients again. So far, this was done by sending PPTP (TCP 1723 and GRE) for the Routing and Windows 2000 RAS server within the network.
According to this post SRP521W, and therefore I guess so the SRP526W, are not able to pass the GRE: https://supportforums.cisco.com/thread/2093204
Is it possible to provide external client VPN access with this router? Perhaps with L2TP (but then you should transmit ESP) or IPSec (ESP and AH as far as I know)?
If there is no solution, we need to replace this device again once with a cheap, simple, router that is able to convey the Grateful - as you can imagine, we would like to save this shame Cisco.
Kind regards
Dominik
Hello Dominik,
The SRP520 only supports IPSec site-to-site at this time.
Advancements are made, please check in the new year.

PIX - PIX VPN and Client VPN - cannot access core network
I hub and spoke PIX and a VPN Client that connects to speak it PIX, much the same as the example configuration here: -.
This example shows the client VPN access to the network behind PIX RADIUS. I want the client to also be able to access the central network, i.e. the client connects to the pix speaks via vpn, and traffic is routed through the vpn to PIX - PIX to the central site.
How this would change the configuration contained in the example?
See you soon,.
Jon
You can not do this, the PIX cannot route a package back on the same interface, it is entered in the. The only way to do that is to have the client connect to the hub PIX, but then they would not be able to get to the network behind PIX distance either.
Or that the customer would connect on a different interface in the PIX of distance, but this would mean another connection ISP on this PIX. Example of config is here: http://www.cisco.com/warp/public/110/client-pixhub.html

The VPN Clients need access to the subnet on another router
Hello
We have a pix 515e PIX Version 8.0 (2)
We have two subnet 10.1.x.x/16 and 10.2.x.x/16
The firewall is on 10.1.x.x and vpn clients can access this subnet.
The firewall can ping 10.2.x.y where x is a server in the other subnet.
On the 10.2.x.x customers out the firewall.
The problem is that vpn clients cannot access the server of 10.2.x.y even if the pix can ping 10.2.x.y and the road for him.
What I need to check that the vpn rules are correct in the pix 515e?
I think it is a rule of exemption nat or something like that not exactly sure.
Everything would be a great help.
Thank you
Hello
For clients VPN access to these subnets, check the following:
1 NAT exemption include these subnets (if not using NAT)... it's the NAT0 ACL command
2. these subnets is included in the split tunneling
3. these subnets have a route to the PIX to send traffic to the VPN client pool.
4. There are no ACLs not applied to the inside interface of the PIX deny this communication.

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.

Can someone tell me what I am doing wrong or what access list I'm missing?
I have two Cisco ASA 5510 firewall with a similar setup configuration and the AnyConnect SSL VPN works great.
Hi Matt,
You are probably landing on the tunnel-group by default - you will need to indicate which group to connect to the client. This can be done in different ways - I see that you already have a defined group aliases, but to be able to use that you must configure:
WebVPN
tunnel-group-list activate
Alternatively, if you have only a single group, you can add 'group-url https://yourasa.yourcompany.com/ permit' to the webvpn attributes tunnel-group.

PIX-to-client VPN and how to reach on other interfaces systems
Hi all
I've implemented a Pix-to-Client VPN and it seems works ok.
As you can see, customer gets the same inside the class address (192.168.100.x) so I can reach across systems.
My questions are:
If I give different subnet pool addresses, how can 1 I still reach inside systems?
2 if I have other systems on these interfaces such dmz1 (192.168.10.0) dmz2 (192.168.20.0) how to get to these systems of the
even the client vpn access?

It is generally preferable to use another range of IP addresses. The PIX will know that the VPN Client uses that vary and route it properly whitch is not the case when you are using the same IP range as the inside interface.
To access another interface use the SHEEP (your ACL 102) access list which disables NAT between the VPN and the neworks to which you want to connect.
Example of config:
access-list allowed SHEEP Internalnet ISubnetMask VPN-pool 255.255.255.0 ip

L to L passing tunnel concentrator 3000 to ASA 5510
Hello
I'm looking in to Lan VPN configuration tunnel the Cisco VPN 3000 to ASA 5510 concentrator Lan. I noticed that this particular configuration has NAT enabled in the hub (Config-online policy management of-online traffic Mgmt-online NAT-online L to L rules)... There are 2 servers NATted to 192.168.1.1 et.2 addresses, so I need to do the same in ASA. Should what steps I take to reach the same configuration in SAA? Is it possible through SDM?
Thank you
Forman
In ASDM-online-online NAT rules configuration, I can create static rule inside indoor int interface and then create the tunnel using 'translated the address' or 'translated network' local area network in the VPN configuration. Is this right?
That is right.
You should NAT the VPN traffic and set the VPN traffic from the translated addresses.
Federico.
