Configuration remote access VPN (IPSec) using FULL domain name
Hi friends of Cisco,
We have the DNS (only the internal IP) within our network, right now that we have configured VPN for remote access using public IP address and connect us with the same public IP address. I need help to use the domain name FULL rather than use public IP.
Can you please provide the configuration for this.
Feature: ASA 5520
Type of configuration: IPSec
Thank you
Estel
Hi Philippe,.
You can use one of the free Web of DNS dynamic sites and configure ASA to dynamic DNS.

Implementation of the remote access VPN IPSec using SRI 2801
Hello
I tried to set up a VPN for remote access using 2801 SRI. I've been able to establish my house vpn tunnel using the DSL (behind a NAT) connection, give it SRI the IP address that is in the ip pool I configured on safety. The problem I have right now is that it does not reach the company LAN network.

I have attached a few screenshots. My goal here is to have access to my LAN to the company (10.10.0.0/24 and 192.168.0.9/24). I don't know what is missing here.
No, we don't need not NAT. wanted to confirm if NAT could cause this problem.
The config looks good. Can you ping routers ip internal interface the client LAN once it connects?
Are correct, w.r.t. transatlantic lines reaching pool behind router VPN?
If so, I would like to take a look at the exits following when a client is connected.

Hi all
I need help with remote access vpn configuration. I want to some remote users who have access to the internet on their system to connect and access an application server in my seat social cisco vpn client user. I use Cisco 881. I am unable to use the SDM configuration because it seems that SDM is not supported by the router so I'm using command line. I'd appreciate any help I can get. Thank you.

Hello Thomas,.
I'm glad to hear that you have found useful in the example configuration.
I checked your configuration and everything seems ok with him, especially the statements of nat.

Try to generate ICMP traffic behind your 100 VLANS to the client VPN in order to answer the following questions:
-The router receives this traffic between VLAN100 unit?
-The router is encrypt this traffic, after receiving the ICMP packet?
#show crypto ipsec router its can help you with this question. Look for the program/decaps counters.
-The same, but the other way around (from VPN client to device behind VLAN100) try to locate the problem.
The following document explains more this crypto commands and debugs if necessary.

Through remote access vpn Ipsec within the host is not available.
Team,
I have a question in confiuration vpn crossed.
ASA 3,0000 Version 5
the only question is, to access remote vpn clinet IP cannot access inside the host. However able to reach the branch of IP and it uses corprate Internet.
In SAA from the external interface I am able to ping remote clint IP but not from within the interface. Please help and let me know if additional information is required.
Thank you

Hello
For the NAT0 configuration, you only need NAT0 instruction for the interface "inside".
This single command/ACL should allow for 'inside' <-->'vpn-pool' communication.
NAT0 configurations on the 'external' interface should be necessary only if you make NAT0 between 2 VPN connections. I guess you could do this since you mention traffic crossed?
I suggest using different 'object-group' to define networks of NAT0 destination for different ' object-group' to the 'outside' to 'outside' and 'inside' users NAT0.
I also obsessively using beaches too wide network in the statements of NAT0. According to some records, they can cause problems
For example, this network ' object-network 172.16.0.0 255.240.0.0 "contains the 172.x.x.x.x set private IP address range. And in this case it contains some of your 'inside' networks too?
How is this a problem of crossed by the way? You say that the problem is between the VPN clients on the 'external' interface and network local hosts behind the 'internal '? Crossed would mean you have connection problem between 'outside' <->'outside' perhaps.
I don't know if I made any sense. Can be a bit messy. But can not give very specific answers that I don't know the entire configuration.
Also make sure you have the "inspect icmp" configured under the policy-map of the world, so that the response to ICMP echo messages are automatically allowed through the ASA.

remote access VPN not connected - no access inside
Hi, I have successfully configured remote access VPN router, it is connected, but no access to the inside, none of my ip addresses. I do not know SPLIT_ACL is ok and I've denied NATting them. For me, everything is ok. I did a lot in ASA, without anyproblem. Thanks for the comments.

Hello
I have 2 Cisco Pix (Pix1, Pix2) 515E (8.0.4). Between these devices exist VPN L2L, which are configured on the external interfaces. On Pix2 I configured remote access VPN on the external interface, too.
Is it possible to achieve LAN behind Pix1, by using remote access VPN on Pix2 then VPN L2L?
I don't want to set up remote access on Pix1.
Thank you very much.
Kind regards
Vladislav
NAT (outside) 1 140.40.30.0 255.255.255.0 (PAT for RA vpn to access the internet if you complete tunnel)
It is simply because I have configured tunnel RA as complete tunnel instead of split, nat (outside) 1 at the RA 140.40.30.0 pool have internet access through your firewall ASA_SITE_B and translate with global ID 1 who is your external interface of the firewall SA_SITE_B. This has nothing to do with what you are trying to accomplish, but I posted it because it was part of the very common scenario. There are some example PIX 6.3 cases where you will need split tunnel so that RA users have internet access not passing not through the encrypted tunnel code 6.0 does not feature of intra-interface support but 7.x above is of the code. Other examples are that some people configure split RA RA user tunnel will have access to their local resources in their homes as the printers network etc...
It is therefore, I need to translate 172.27.1.0/24 RA pool?
No there is no address translation in place in this scenario to work and you don't need to translate something too long, there is no of networks that overlap in one of the SITES u do not need to translate, this scenario is completely free sheep as you access lists free of nat in two firewalls for networks involved in communication in tunnels ASA_SITE_B.
Because I want to see IP addresses from PIX_SITE_A to 172.27.1.0/24, not 140.40.30.0/24. Is it possible to do it this way?
Im not clear on this issue, but if I think what it means, it's possible but you need to have political NATing but I think this will make complicated setup, I would say to make this as simple as possible.

Configure ASA5055 as a remote access VPN client
Hello world
I'm trying to configure a 5505 as a remote access VPN client. I have several old hubs VPN 3002, but in the new sites I'll use a 5505 instead of these 3002.
I think that the configuration is very simple. I have the IP address of the peer (remote server), I know it is an IPsec tunnel without certificate and I have passwords and user name and group.
How can I translate this configuration for an ASA5505? I have attached a screenshot.
Here ya go:

How to use ACS 5.2 to create a static ip address user for remote access VPN
Hi all
I have the problem. Please help me.
Initially, I use ACS 4.2 to create the static ip address for VPN remote access user, it's easy, configuration simply to the user defined > address assignment IP Client > assign the static IP address, but when I use ACS 5.2 I don't ' t know how to do.
I'm trying to add the IPv4 address attribute to the user to read "how to use 5.2 ACS", it says this:
1Ajouter step to attribute a static IP address to the user attribute dictionary internal:
Step 2select System Administration > Configuration > dictionaries > identity > internal users.
Step 3click create.
Static IP attribute by step 4Ajouter.
5selectionnez users and identity of the stage stores > internal identity stores > users.
6Click step create.
Step 7Edit static IP attribute of the user.
I just did, but this isn't a job. When I use EasyVPN client to connect to ASA 5520, user could the success of authentication but will not get the static IP I set up on internal users, so the tunnel put in place failed. I'm trying to configure a pool of IP on ASA for ACS users get the IP and customer EasyVPN allows you to connect with ASA, everything is OK, the user authenticates successed.but when I kill IP pool coufigurations and use the "add a static IP address to the user 'configurations, EzVPN are omitted.
so, what should I do, if anyboby knows how to use ACS 5.2 to create a user for ip address static for remote access VPN, to say please.
Wait for you answer, no question right or not, please answer, thank you.
There are a few extra steps to ensure that the static address defined for the user is returned in the Access-Accept. See the instuctions in the two slides attached

How to prohibit remote access vpn client to use the local DNS server
Hello
I'm on ASA5505 remote access vpn configuration.
Everything works fine so far, except when the client got connected, he always used the local DNS server provided by the ISP. How can I force the customer to use the DNS server configured on ASA?
Thank you.
Kind regards
The command "Activate dns split-tunnel-all" is supported only on SSL VPN and VPN IKEv2. Since you're using IKEv1, this command is not supported.
Here's the order reference:
http://www.Cisco.com/en/us/docs/security/ASA/asa82/command/reference/S8.html#wp1533793
You configure no split tunnel? If you are, then you need to configure "tunnelall" split tunnel policy, and that will force the dns resolution and everything else through the VPN tunnel.

Hi all:
Mystery - I have a Win 7 work company that cannot access a particular action. I get the following error-"you are not allowed to access \\server\users. Contact your network administrator to request access. However, these users can access these files successfully on other computers, and also if I use the fqdn or the IP instead of the "netbios name server", it connects successfully.
Environment:
-Workstation and server at the same time in the same AD Windows 2008 r2 domain.
-All users, admin and non admin, cannot access this share when connecting to this computer only.
-ACCESS to the other actions on the same server, as well as actions on other servers.
-The biggest mystery to me - if I type the FQDN, \\server.domain.local\users, it works! What the?
I tried:
-Deletion of the domain and add it again, no improvement.
-Check Event Viewer, nothing jumps (not red or yellow).
-Enabled auditing for access to objects on the server, it does not show a failure in the security event log.
-Turn off the firewall of my computer.
-UN-share and re - share the directory.
-Give everyone full control (the fact that it works well with de facto authorities a little full domain name, a candidate little likely, but I have an open mind).
For anyone wishing to offer their 'help' by asking me to make some sort of workaround as re - install windows or turn off netbios or use only of the full domain name here on out or whatever, please Don ' t bother. I appreciate your help, but I am quite able to reinstall and I'm not interested unique hacks that affect this otherwise network well managed, I'm looking for a solution that will allow me to save time and is a long-term solution.
In my view, that a key point here maybe I can connect successfully using \\server.domain.local\users, but not \\server\users. Someone at - it some thoughts?
In DNS server of youe, go to the area in question and in the use of select search before Wins wins tab and enter the address of your wins server if you have one. If not, install one.

authentication of remote access, vpn and ldap
I have a test environment with 2 hours fireval 5505: the first firewall is remote access VPN server and the Interior of this firewall is a network of domain with a domain controller, DNS server and a workstation. DHCP is disabled and the PC have a static address.outside of the VPN server is attached outside the other ASA 5505 firewall. on the inside of the firewall, there is a workstation.the workstation would be to connect via vpn for remote access on the domain network. I have configured the VPN server for remote access through a wizard and his
configuration is the following

When I tried to workstation on the internal part of the second firewall (no remote access vpn server) to connect to the vpn, everything is ok. I used the cisco vpn client, but I can't ping domain controller, workstation, I can't use the shared folder on them. Why?
Please help me
Thank you
Thanks for letting me know! Can you please give the station "answered"? Thank you!

VPN IPSec using possible FWSM?
Hello
Is it possible to configure a module 6500 FWSM to allow a windows-based IPSEC VPN to put end to this and to allow access to the network protected inside.
Documentation for the FWSM talks about the configuration of the FWSM for remote access and management using a VPN. but it does not mention anything to have the vpn in the protected network.
Please tell me all the links on CCO.
Thank you
Verhasselt
Well, it's really simple...
Add the devices you have to complete the IPSec VPN. You're right, none of the components that you will allow you to IPSec VPN (at least not without assistance to complete a debit)...
Add a VPNSM (or the more fancy SPA-IPSEC solutions..) in each 6500 or put a VPN device size on each side...
Did she help?

ASA to remote access VPN with external IP dynamic
Hi forum,
I was wondering if it was possible to set up an ASA to provide access to remote connections VPN (IPSEC or WebVPN/SSL) of the outside world, if the external IP address is dynamic (i.e. obtained through DHCP)? I understand how to use DynamicDNS to provide a host name for the VPN clients, I ask simply if the SAA can be configured to allow VPN connections from a DHCP interface addressed. I understand there are problems with the site to site VPN when both sides are addressed in a dynamic way, but it seems that the remote VPN access should work. Just hoping to confirm this before I go and I'm working on a config.
Thanks in advance...
The same configuration applies.
In my view, that the only difference is that with the external IP being dynamic:
interface e0/0
IP address dhcp setroute
crypto map
The only difference is that (the PCF file) VPN clients should have the VPN connection with a hostname (rather than an IP address) and the IP must be solved at the IPs of the SAA.
I'll try to find you an example configuration if you do not.
Federico.

Problem with remote access VPN
Hello
I installed a remote access VPN on my firewall ASA5505 via the ASDM Assistant.
I can successfully connect with the Cisco VPN client. My firewall also shows me the VPN session and shows the Rx packets. However, Tx packets remain 0, so no traffic is getting out. My ASA5505 is configured as a router on a stick with 25 different VLAN. I want to restrict traffic to one VLAN specific using a card encryption.
When I run a command to ping t on my connected Windows box, the firewall log shows me the following message:
"Unable to find political IKE initiator: outside Intf, Src: 10.7.11.18, Dst: ' 172.16.1.1
"This message indicates that the fast path IPSec processing a packet that triggered of IKE, but IKE policy research has failed. This error could be associated calendar. The ACL triggering IKE could have been deleted before IKE has processed the request for initiation. "This problem will likely correct itself."
Unfortunately, the problem is correct.
The "sh cry isa his" and "sh cry ips its ' commands show the following output:

I really have no idea what's going on. I installed a remote access VPN countless times, but this time it shows me the error as described above.
Hi Martijn,
just a few quick thoughts:
-is your ok NAT exemption, i.e. ensure that the return traffic is not NAT' ed.
-Make sure that there is no overlap crypto ACL
-When connected, make a package tracer to see what is happening with the return packages.
for example
packet-tracer in the interface within the icmp 10.7.11.18 0 0 172.16.1.1 detail
(where is the name of the interface on which 10.7.11.18 resides)
This will show you all the steps the rail package in-house (routing, nat, encryption etc.) so it should give you an idea of what is happening, for example when it comes to the bad interface, nat evil rule, wrong entry card crypto etc.
