Network Concentrator VPN access.
We have a 3000 Concentrator and is configured with a remote vpn on it. All inside network is allowed once a connceted to the vpn user. It is quite behind firewalls. I can access an external IP.
But I can't log in to the vpn from the inside network. I can ping the public interface; but when I try to log in from the client, the server report displays no records to my IP.
Why can't I connect from the inside?
Thank you
= Internal network = Concentrator VPN = FW = off-grid
Why try you to VPN from the inside? The purpose of the VPN is to encrypt the traffic between your PC over the internet to the VPN concentrator, once traffic arrives to your VPN concentrator, it is decrypted, and he'll be in the clear to your internal network.
So, what's the purpose of attempting to connect from the network Cabinet?
The reason why it does not work is because of the delivery. You are on the internal network, while traffic will exit to the firewall and return by the same firewall to connect to the public interface of the VPN concentrator, which is why it does not work and if the goal is access to the internal network, you are already inside the network which complicates things as your ip pool must then be routed to the inside.
Hope that makes sense.

We have Concentrator VPN 3030 with software version 4.7.2.J. We use to manage graphical interface using HTTPS access. The problem, now, is that we are not in a position of HTTPS (on the private interface) to manage the hub by GUI. However, the device can be telneted to port 443 and is also accessible by telnet. We have also restarted the unit twice.
Is this some sort of BUG or something misconfigured?
Here is some information for you on this issue. I think you have to re - generate the certificate on the hub. HTH

ASA5505 can transfer clients to remote VPN access to the local network
I have currently ASA 5505 and 2911-router and I am trying to configure the VPN topology.
Can ASA5505 you transmit to remote VPN access clients LAN operated by another router?
These two cases are possible? :
(1) ASA 5505 and 2911-router are separate WAN interfaces, each connected directly to the ISP. But so can I connect an other interfaces LAN of ASA 5505 in a switch managed by 2911 router customers to distance-SSL-VPN to inject into the local network managed by the router?
(2) ASA 5505 is behind router-2911. May 2911 router address public ip or public ip address VPN-access attempts have directly be sent to ASA 5505 when there is only a single public ip address address available?
Long put short, ASA 5505 can inject its clients to remote-access-VPN as one of the hosts on the local network managed by 2911-router?
Thank you.I could help you more if you can explain the purpose of this configuration and connectivity between the router and ASA.
You can activate the reverse route on the dynamic plane on the SAA. The ASA will install a static route to the customer on the routing table. You can use a routing protocol to redistribute static routes to your switch on the side of LAN of the SAA.

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.

Access to a remote network through VPN remote access
Hello
I'm having a problem with users who access VPN from home. We currently have 3 offices facility, as shown below. When I VPN in the Philadelphia office, I am unable to access the resources of Connecticut offices or North Carolina.
The VPN subnet is 192.168.10.0. Inside the office of the PA, I have no problem with NC or CT. I have to add a static route from the Pennsylvania Treasury and NC? If so, could you give me a hand with the correct syntax?
Office <-----------IPSecVPN---------->Office <------------IPSecVPN------------->Office of Connecticut from Pennsylvania, North Carolina
192.168.5.0 192.168.1.0 192.168.2.0
Hello
Yes, basically the ASA accommodation the customer VPN service in this case well enough is the same configuration related to two sites with the exception of course which is obvious
- Networks/subnets
- Different ACL for each VPN L2L
Although naturally the problem for me is the WRVS4400N configuration.
Basically, you do the same things on this unit than the other remote site.
You add the VPN pool as another remote network for VPN L2L configurations. You also confirm that there is operation NAT0 for this network also. I don't know I can help you there as I do not know the device.
Can you please mark it as answered and evaluate other useful answers
Naturally ask for more and I'll try to help you if I can

Cannot access remote network via VPN
Hello
I'm trying to set up a router vpn access to my office network. The router is connected to the Internet through using pppoe vdsl.
There is also a public oriented Web server in the office which must be accessible.I can access the Web server from the Internet and the vpn connects successfully. I can also ping the LAN Gateway, however, I can't access all the local machines.
I'm quite puzzled as to why it does not work. Please could someone help.
The results of tests and the router configuration are listed below. Please let me know if you need additional information.
Thank you and best regards,

!Simon,
Basically when you connect through a VPN Client PC routing table is updated automatically as soon as the connection is established. If you do not need to manually add routes. You can check this by doing a "route print" once you are connected.
Ideally, you need to put your pool of VPN on subnet that does not exist on your physical network, the router would be to route traffic between the IP pool and internal subnet.
Now, you said that you have a web server with a public IP address that you need to access through the VPN, that host also as a private IP addresses on the 172.16.100.0? If it isn't then the ACL that I proposed should work. If she only has a public IP then your ACL VPN address must have something like
IP 172.16.100.0 allow 0.0.0.255 192.168.100.0 0.0.0.255
219.xxx.yyy.192 ip 0.0.0.7 permit 192.168.100.0 0.0.0.255
Who says the router and the client to encrypt all traffic between the subnets behind your router and your VPN pool.
I hope this helps.

ciscoasa # $Still, I can't ping ASA remote outside from outside of the Local interface. And there is no connectivity between the 192.168.80.0 distance and local don't say 192.168.1.0. I have run out of ideas
Would appreciate any help. Thank you in advance...
If the tunnel is up (phase 1), but no traffic passing the best test is the following:
Add order management-access to the Interior , and then try to PING the intellectual property inside ASA counterpart.
inside x.x.x.x ping --> x.x.x.x is the IP of the ASA peer inside
The test above shows if the traffic passes through the tunnel (check encrypted/decrypted packets of sh cry ips its).
Test on both directions.
Please post the results.

VPN access no longer works after upgrade from 10 IOS! Any input to fix?
VPN access no longer works after update IOS 10! With the help of an iPhone 5 or 6, our employees use their hotspot phone to connect to our VPN. Suddenly, he broke Monday after the upgrade to IOS 10. We have experienced many versions of IOS, and it has always worked. Any patch available?
Hello howlindaug,
Thank you for using communities of Apple Support.If I understand your message that your employees will no longer be able to connect to your virtual private network with their iPhone 5 or 6 after the upgrade to iOS 10. Sierra Mac OS and iOS 10 delete a VPN profile PPTP connections when a user upgrades from their device. If your VPN is a PPTP connection, you'll want to use one of the options listed in the section below:
Prepare for removal of PPTP VPN before upgrade you to iOS 10 and macOS Sierra
Alternatives for PPTP VPN connections
Try one of these other VPN protocols for authentication by user that are safer:
- L2TP/IPSec
- IKEv2/IPSec
- Cisco IPSec
- VPN SSL clients on the App Store, such as those of AirWatch, Aruba, Check Point, Cisco, F5 Networks, MobileIron, NetMotion, Open VPN, Palo Alto Networks, Pulse Secure and SonicWall
Best 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.

Concentrator VPN 3020 - wait of disconnection from the user before extinction
Dear Forum community!
We have a 3020 Cisco Concentrator VPN Balancing cluster configured, the device on main site with top priority. We would like to stop the master device due to short maintenance.
I wonder if there is an option in GUI of VPN concentrator, waiting for all active sessions for volunteers end before the start/stop. Does anyone have experience on this feature?
There are still about 80-100 remote user access VPN online and don't want to break the connections of these users with a simple poweroff.
Thank you and BR
Belabacsi
Budapest, Hungary
I just wanted to clarify two things.
I always save my configuration file before restarting. That's why I restart without saving the changes. I think that my wording could mislead.
If you need your customers to be re - authenticate the VPN session after a period of time, for example 10 hours, the VPN session will be moved to another Member of the cluster when the session is authenticated again. Each client must re-establish the VPN session on another hub in the cluster. If you do not use this feature, you will need to wait until each of them ends its VPN session.

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)

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
Noman Bari
I see what rou are... Please see my attchement...
Please rate if it helps!

I went through the forum messages to allow VPN access to a DMZ host but miss me something and hoping another set of new look will see the question. Basically, need a VPN profile to allow the service provider to a host in the demilitarized zone. VPN connects but I can't access the host. Here is the config and Yes its an old Pix 515 running version 7.2 (5) - will get new firewall soon.
Thank you
Gary

Gary,
Configure "crypto isakmp nat - t" and test it.
If it still does not work, please download the following information from the configuration, after connecting the customer:

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.

Cannot ping inner network via VPN site-2-site
I have the following Setup of the site 2 site VPN.
The pain I feel is host 172.168.88.3 in site A is not able to ping 172.168.200.3 in site B and vice versa. Think I've added static routes and lists ACLs correctly on 3560 switches (acting as an access point) and the two PIX to access internal networks. 172.168.9.3 host can ping 172.168.200.3 very well. All advice is appreciated.
Thank you very much.

Hi Robert,.
I went through the configuration on both the PIX firewall and see that trafficking is not defined for 172.168.88.0/24-->172.168.200.0/24.
If you check the card crypto a PIX configuration, it says:
address for correspondence outside_map 20 card crypto outside_cryptomap_20<--This acl="" defines="" interesting="">
and the outside_cryptomap_20 of the acl says:
access extensive list ip 172.168.9.0 outside_cryptomap_20 allow 255.255.255.0 172.168.200.0 255.255.255.0 connect
Is the same on the PIX B:
address for correspondence outside_map 20 card crypto outside_cryptomap_20
access extensive list ip 172.168.200.0 outside_cryptomap_20 allow 255.255.255.0 172.168.9.0 255.255.255.0
To allow users to talk to each other, apply to these commands:
On the PIX:
access extensive list ip 172.168.88.0 outside_cryptomap_20 allow 255.255.255.0 172.168.200.0 255.255.255.0
access extensive list ip 172.168.88.0 inside_nat0_outbound allow 255.255.255.0 172.168.200.0 255.255.255.0
and PIX B:
IP 172.168.200.0 allow access-list extended outside_cryptomap_20 255.255.255.0 172.168.88.0 255.255.255.0
access extensive list ip 172.168.200.0 inside_nat0_outbound allow 255.255.255.0 172.168.88.0 255.255.255.0
Let me know if it helps.
Thank you
