Cannot access remote VPN site-to-site VPN
Internal network: 192.168.0.0/16
The remote VPN Clients: 192.168.0.100 - 192.168.0.254
Remote (L2L) network: 10.10.10.0/26
Remote VPN Clients are able to access the internal network without problem, but are unable to access the remote 10.10.10.0. Is it possible to debug this? "packet - trace" show no problem...
Hi Ben,
Please create a no. - nat on the external interface, because your customers to vpn-remote and remote-L2L tunnels are located on outside interface (i.e. from the outside). You should treat your outside network identical to your inside network, as you would create a no. - nat for your inside networks.
The ACL you create for the no - nat outside must be in both directions as below.
permit access ip 192.168.0.0 scope list outside_nat0 255.255.255.0 10.10.10.0 255.255.255.192
outside_nat0 to access extended list ip 10.10.10.0 allow 255.255.255.192 192.168.0.0 255.255.255.0
NAT (outside) 0-list of access outside_nat0
permit same-security-traffic intra-interface
Pls let me know, if this is useful.
Thank you
Rizwan James

AnyConnectVPN users cannot access remote vpn site-to-site
Hello-
We have two 5510 s ASA one in 8.4 (4) and the other to 8.2 (5) in a site to site VPN configuration. All internal traffic is working smoothly.
A: site/subnet 192.160.0.0 - local (8.4 (4)) Site/subnet b: 192.260.0.0 - distance (8.2 (5)) VPN users: 192.160.40.0 - assigned by ASA
When you VPN into the network, all the hits of traffic A Site and everything on the subnet A is accessible.
However, the site B is totally inaccessible to users of VPN. All computers on subnet B, the firewall itself, etc. is not reachable by ping or otherwise.
There are also some NAT rules weird that I'm not happy with that were created after that I upgraded the Site to ASA to 8.4
A resident of the site: external 192.160.x.x: 55.55.555.201(main)/202(mail)
Site B (in addition to site to site) is external 192.260.x.x: 66.66.666.54 (all)
I've pretty much just the basic rules of the NAT for VPN, Email, Internet and site to site.
What I need to add for the VPN access to the network from site to site?
Here is my config NAT:
NAT (inside, outside) static source DOMAIN_LOCAL DOMAIN_LOCAL VPN_Network VPN_Network non-proxy-arp-search of route static destination
NAT (inside, outside) static source DOMAIN_LOCAL DOMAIN_LOCAL DOMAIN_REMOTE DOMAIN_REMOTE non-proxy-arp-search of route static destination
!
network of the DMZ_Network object
dynamic NAT interface (DMZ, outside)
network of the DOMAIN_LOCAL object
NAT dynamic interface (indoor, outdoor)
network of the EXCHANGE_Exchange object
NAT static Outside_Mail (any, any)
network of the DOMAINCTRL_DHCP object
NAT (inside, outside) interface static tcp ftp ftp service
Thank you very much in advance and I hope that I've been pretty thorough.
Let me know if you need anything that anyone else. Thank you!!
Theo,
You don't need the NAT rules outside (depending on your configuration).
Basically, you need to add the pool VPN L2L traffic and network remote to the ACL of split tunneling (if configured), also the "permit same-security-traffic intra-interface".
Please let me know.
Thank you.

2 VPN SITE to SITE with ACCESS REMOTE VPN
Hello
I have a 870 router c and I would like to put 2 different VPN SITE to SITE and access remote VPN (VPN CLIENTS) so is it possible to put 3 VPN in the router even if yes can u give me the steps or the sample configuration
Concerning
Thus, on the routers will be:

!
crypto ISAKMP client configuration group ra-customer

!
Please note that the configuration is incomplete, I added that relevant changes, you should bring to the allow clients of RA through the LAN-to-LAN tunnel, of course, the LAN-to-LAN settings should match to the other side of the tunnel that is mirror of ACL, NAT and so on.

Cannot access a Web site using Java Script
Cannot access a Web site using Java Script. I'm not sure what it blocks I use Win 7, Avast free, AntimalwareBytes.
I get a pop up window with
Name: mcs
Location: http://myspeedtest02.windstream.net
say "application blocked by security settings, blocking the untrusted application.
I don't know what it blocks, but suspect it is related to the security of Windows.
I think that the Java Applet is blocked, but I would like to run this test of speed from my ISP. I tried to access the website of Google Chrome and IE, with the same result. Nobody knows what this block and how to unlock it?This is actually not JavaScript, it's Java. Despite the name, they are really very very different.
Java itself can be dangerous, especially if it is not a trusted application. It is my sincere recommendation that you do not continue.
If you want anyway, you can go into your control panel, open the Java settings and set it to allow untrusted applications.

VPN clients cannot access remote sites - PIX, routing problem?
I have a problem with routing to remote from our company websites when users connect via their VPN client remotely (i.e. for home workers)
Our headquarters contains a PIX 515E firewall. A number of remote sites to connect (via ADSL) to head office using IPSEC tunnels, ending the PIX.
Behind the PIX is a router 7206 with connections to the seat of LANs and connections to a number of ISDN connected remote sites. The default route on 7206 points to the PIX from traffic firewall which sits to ADSL connected remote sites through the PIX. Internal traffic for LAN and ISDN connected sites is done via the 7206.
Very good and works very well.
When a user connects remotely using their VPN client (connection is interrupted on the PIX) so that they get an IP address from the pool configured on the PIX and they can access resources located on local networks to the office with no problems.
However, the problem arises when a remote user wants access to a server located in one of the remote sites ADSL connected - it is impossible to access all these sites.
On the remote site routers, I configured the access lists to allow access from the pool of IP addresses used by the PIX. But it made no difference. I think that the problem may be the routes configured on the PIX itself, but I don't know what is necessary to solve this problem.
Does anyone have suggestions on what needs to be done to allow access to remote sites for users connected remotely via VPN?
(Note: I suggested a workaround, users can use a server on LAN headquarters as a "jump point" to connect to remote servers from there)
with pix v6, no traffic is allowed to redirect to the same interface.
for example, a remote user initiates an rdp session for one of the barns adsl. PIX decrypts the packet coming from the external interface and looks at the destination. because the destination is one of adsl sites, pix will have to return traffic to the external interface. Unfortunately, pix v6.x has a limitation that would force the pix to drop the packet.
with the v7, this restriction has been removed with the "same-security-traffic control intra-interface permits".

Remote VPN users cannot access tunnel from site to site
Cisco ASA5505.
I have a tunnel of site-to-site set up from our office to our Amazon AWS VPC. I'm not a network engineer and have spent way too much time just to get to this point.
It works very well since within the office, but users remote VPN can not access the tunnel from site to site. All other remote access looks very good.
The current configuration is here: https://gist.github.com/pmac72/f483ea8c7c8c8c254626
Any help or advice would be greatly appreciated. It is probably super simple for someone who knows what they're doing to see the question.

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.

AnyConnect VPN users cannot access remote subnets?
I googled this until blue in the face without result. I don't understand why Cisco this so difficult? When clients connect to the anyconnect vpn, they can access the local subnet, but cannot access the resources in remote offices. What should I do to allow my anyconnect vpn clients access to my remote sites?
Cisco 5510 8.4
Hello
What are remote sites using as Internet gateway? Their default route here leads to the ASA or have their own Internet gateway? If they use this ASA for their Internet connection while they should already have a default route that leads traffic to the VPN to the pool, even if they had no specific route for the VPN itself pool. If they use their own local Internet gateway and the default route is not directed to this ASA then you would naturally have a route on the remote site (and anything in between) indicating the remote site where to join the pool of 10.10.224.0/24 VPN network.
In addition to routing, you must have configured for each remote site and the VPN pool NAT0
Just a simple example of NAT0 configuration for 4 networks behind the ASA and simple VPN field might look like this
object-group network to REMOTE SITES
object-network 10.10.10.0 255.255.255.0
object-network 10.10.20.0 255.255.255.0
object-network 10.10.30.0 255.255.255.0
object-network 10.10.40.0 255.255.255.0
network of the VPN-POOL object
10.10.224.0 subnet 255.255.255.0
NAT static destination DISTANCE-SITES SITES source (indoor, outdoor) REMOTE static VPN-VPN-POOL
The above of course assumes that the remote site are located behind the interface 'inside' (although some networks, MPLS) and naturally also the remote site networks are made for the sake of examples.
Since you are using Full Tunnel VPN should be no problem to the user VPN transfer traffic to this ASA in question.
My first things to check would be configuring NAT0 on the ASA and routing between remote sites and this ASA (regarding to reach the VPN pool, not the ASA network IP address)
Are you sure that the configuration above is related to this? Its my understanding that AnyConnect uses only IKEv2 and the foregoing is strictly defined for IKEv1?

a public access remote vpn from an inside interface asa 5505
I'm trying to see if it is possible to accomplish what I am trying. I have an ASA 5505 with the following configuration.
1. There is an external connection, connected to the ISP. Let's say that it is 10.1.1.1/24 for ease. There is a remote VPN configuration as the access of people through this interface.
2. There's the inside network, which is the normal LAN. It's cable system in the office. to say that it is 172.20.0.1/24.
3. There is a wireless network on a VLAN separate called WLAN. It has an IP of 192.168.1.1/24. There is an ACL allowing traffic to that VLAN to the public internet.
Essentially, I would like users to be able to use the same VPN settings they use when connecting from outside of the Office when you are connected to WIFI.
Also, I would like that they can access public IP addresses that I have NAT would be to internal servers. In this way, they can use IP addresses when they use on the public internet.
Is this possible?
Hello
Well that's not going to be possible, the only thing you can really do is to activate the crypto map on the WLAN facing interface, by design, you cannot not access VPN, ping or manage the device on an interface which is not directly connected to you.
I hope this helps.

Cannot access https secure sites after installation of Netnanny
Use Firefox for years. Then recently installed "net nanny" software and it has changed the security settings on Firefox.
I can't access all the secure https sites regardless of whether net nanny software is even uninstalled.
The following alert occurs on Firefox running...
"Could not initialize component of application security. The most likely cause is problems with the files in the directory of the profile of your application. Please check that this directory has no restriction of read/write and your hard disk is not full or close to full. It is recommended that you exit the application and correct the problem. If you continue to use this session, you may see incorrect application behavior when you access security features. »Then when you try to access an https site, I get an error as follows:
"Secure connection failed".An error occurred during a connection to support.mozilla.com.
Cannot connect securely because the SSL protocol has been disabled.
(Error code: ssl_error_ssl_disabled) »
Use SSL 3.0 and use TLS 1.0 are both selected in the "Advanced settings"
I also left a post on the forum of Net nanny however clearly don't have an adequate response when they talk about a setting in their software ("allow secure content") which is already activated anyway with the uninstalled software, however it still does not solve the problem. In fact, I had to use IE to post on this forum.
It clearly provided a message when configuring the net nanny that he changed the security settings when Firefox has been executed for the first time for each user.
I wish I had a solution so I can go back to using Firefox as my default browser and do believe a software application and a well known who, should take a non-functional browser but not another.
Start with this support article:

1920 router access remote vpn LDAP living
Hello
What is required for a router in 1920 use AnyConnect and/or also integrate with AD LDAP?
Currently, this router supports legacy clients and has these licenses:
Technology for the Module package license information: "c1900".
-----------------------------------------------------------------
Technology-technology-package technology

------------------------------------------------------------------
IPBase ipbasek9 ipbasek9 Permanent

given none none noneThe vpn to access remote client inherited integrate with AD LDAP?
Thank you.
As long as you are on IOS 15.3.3M3 or better, you have all the licenses you need for 3.1 AnyConnect run on your 1921.
The guide to directly connect your router to LDAP can be found here:
Personally, I would avoid directly interfacing with LDAP, because it can be a complex arrangement. While it can be done, it's easier to have your router to connect to the NPS Microsoft via RADIUS server for your authentication.

Hello
Im trying to figure out why vpn for remote access is at our company office fails. The scenario: we currently have a work situation. The way this works is that users connect to the public ip address of the DSL router and nat vpn traffic to an internal router. This router then forwards the traffic to the vpn server.
vpn client remote <=>{{internet}} <=>cpe <=>adsl router <=>vpn server
Now, Im implementation of a 2nd internet line with more or less the same configuration, but instead of an adsl cpe, we use a cisco router. When users need to connect even with the only difference being a different public ip address
client remote vpn <=>{{internet}} <=>cisco <=>router <=>router, vpn server
So, the only change in the prepective of cisco vpn clients is the host. However when testing, it didn't work. The vpn client times out. With something like 'the vpn peer did not' do not remember the exact error by heart. Now logic tells me that because he now works in the part between the internal router and the vpn gateway is ok. My guess is it's because of the cisco access list. I had my own list of access, but for some reason, I decided to use firewall SDM Wizard configuration and it generated this access list.
Expand the IP 100 access list

180 deny host ip 0.0.0.0 everything
190 deny ip any any newspaper (5163 matches) Extended 100 IP access list
Given that the natting to the smtp protocol works, I think that the natting is ok. I ping the server vpn, so routing also seems to be ok. Vpn users receive a vpn ip address pool 192.168.x.x. is it possible that the 150 rule that prevents them to connect? I can't test, because it's a living environment and I'll have to plan a window. Im just trying to figure out what is wrong, so I can fix it for a window. Someone at - it ideas?
No, you don't need AH if your VPN policy does not include AH.

Access remote VPN question - hairpin
Hello, I did a search before posting this question but I have not found anything specific to my situation.
We have our ASA5520 configured in our main office to allow remote access Cisco VPN client users to access our network. We have a (network 192.168.1.0/24) remote desktop we have a configured on the same ASA5520 VPN IPSec tunnel that allows the use of internal users (in the main office) to access resources on the network remote (192.168.1.0) and vice versa. The problem is that when users connect to the remote VPN access, they are not able to access the resources of the remote office network. We created the nat0 ACL and labour, and split tunnel routing is implemented for users VPN remote network access (if I make a copy of the route on my laptop after connecting to the VPN, I see the road to 192.168.0.0/24 in my routing table). Routing everything is in place to do this, since the IPSec VPN tunnel is up and working. My suspicion is that the question has something to do with the consolidation of these VPN clients.
What else needs to be configured to work? Thank you.
Hi Scott,.
I have a client with a PIX 515E which allows connections to remote VPN and VPN LAN2LAN multiple connections.
We had this problem too... so what I made in my pix was:
TEST (config) # same-security-traffic intra-interface permits (its off by default)
If you use ASDM go to:
Configuration > Interfaces >
at the bottom of this page, there is an option that says: 'enable traffic between two or more host computers connected to the same interface '.
Check and it should work... I hope
I await your comments...
Kind regards.

Web searches are redirected to OpenDNS. Cannot access these Web sites.
This problem just started. Whenever I try to load a page (in this case Gamefaqs), I get redirected to this search engine called openDNS, saying that the site is not available. It has a link to the site, and whenever I clicked, it redirects me to this thing OpenDNS.
I tried loading the page with the default browser of chrome on this phone, but also my laptop using firefox and chrome and have not experienced this problem. Yet the problem persists when you try to access the mobile site through firefox.
I have tried clearing the cache, uninstall and reinstalling, yet the problem isn't resolved. I have done a virus scan, thinking it might be some form of malware that is hijacking my search engine. That all comes back clean.
I've never heard of OpenDNS, nor have I allowed it to become my search engine. When I go into the settings of search engine, it does not appear, but he manages to keep hijacking of my searches on google and redirect me sites that work normally.
Please help me.
Hi SuperRup91, I was able to reproduce this problem on Firefox Mobile on a wi - fi network using OpenDNS. Queries for a single word for non-existent domains + by pressing the arrow go back a page of results of OpenDNS. Typing a search suggestion next to the icon of Google for the word, or by using a query of several given word of Google results. Unless you can change to a different DNS provider, I think you may be stuck with these options.

Hi Max,.
Please send me the output of 'see the anyconnect vpn-sessiondb' once connected with VPN.
And try to add the following configuration and see if that helps:
NAT (inside, outside) 1 static source NETWORK_OBJ_172.19.88.0_24 NETWORK_OBJ_172.19.88.0_24 static destination VPN-VPN-POOL no-proxy-arp-route search
And one more qusetion do you use split tunnel? If yes then you must make the following changes, because your split tunnel is incorrect, in the split tunnel, you have configured the address pool of vpn. Please make the following change:
no access list SPLIT_TUNNEL standards not allowed 10.0.0.0 255.255.255.0
Standard access list SPLIT_TUNNEL allow 172.19.88.0 255.255.255.0
Group Policy attributes "GroupPolicy AnyConnect"
Split-tunnel-policy tunnelspecified
value of Split-tunnel-network-list SPLIT_TUNNEL
Let me know if this can help, or if you have any questions, more about it.
Thank you
Jeet Kumar

I just reinstalled Lenovo Solutions Center (3.2.002) - wow! Nothing like the previous version and would seem to be a lot less useful. After the execution of the first analysis equipment, all is well except for two topics that are unexplained. The P
