VPN-filer configuration on the VPN traffic
Hello world
We set up a site to ipsec with the seller.
For security reasons we do not want to allow all traffic through the tunnel.
ASA has 2 interfaces both inside and outside.
We refuse any one on the external interface ip.
I have config vpn run ACL to allow traffic on port ssh, icmp through the tunnel.
Then I applied it under the group policy.
name of VPN-filter value.
Need to confirm that I must also allow ipec protocols as esp etc under VPN filter ACL?
Concerning
MAhesh
The vpn-filter is applied to the traffic flowing through the tunnel. You don't need to allow all traffic that 'built' like IKE and IPsec VPN.
On the SAA, you must also add this traffic to your external ACL is it necessary on IOS routers.
For the vpn-filter, be aware that the syntax is not
permit/deny PROTOCOL SOURCE DESTINATIONIt's
permit/deny PROTOCOL REMOTE LOCALThis is relevant when you want to filter traffic from your network to the network of peers.

Configuration of the router to allow VPN traffic through
I would like to ask for assistance with a specific configuration to allow VPN traffic through a router from 1721.
The network configuration is the following:
Internet - Cisco 1721 - Cisco PIX 506th - LAN
Remote clients connect from the internet by using the Cisco VPN client. The 1721 should just pass the packets through to the PIX, which is 192.168.0.2. Inside of the interface of the router is 192.168.0.1.
The pix was originally configured with a public ip address and has been tested to work well to authenticate VPN connections and passing traffic in the local network. Then, the external ip address was changed to 192.168.0.2 and the router behind.
The 1721 is configured with an ADSL connection, with fall-over automatic for an asynchronous connection. This configuration does not work well, and in the local network, users have normal internet access. I added lists of access for udp, esp and the traffic of the ahp.
Cisco VPN clients receive an error indicating that the remote control is not responding.
I have attached the router for reference, and any help would be greatly apreciated.
Manual.
Brian
For VPN clients reach the PIX to complete their VPN the PIX needs to an address that is accessible from the outside where the customers are. When the PIX was a public address was obviously easy for guests to reach the PIX. When you give the PIX one address private, then he must make a translation. And this becomes a problem if the translation is dynamic.
You have provided a static translation that is what is needed. But you have restricted the TCP 3389. I don't know why you restricted it in this way. What is supposed to happen for ISAKMP and ESP, AHP traffic? How is it to be translated?
If there is not a static translation for ISAKMP traffic, ESP and AHP so clients don't know how to reach the server. Which brings me to the question of what the address is configured in the client to the server?

How to create a VPN file .pcf for the CISCO VPN CLIENT software profile
Dear all
How to create a VPN file .pcf for the CISCO VPN CLIENT software profile
Concerning
Hi Imran,
Can't do much about that because it depends on what authenticate you the VPN server and how the settings. But let me introduce you to the memory layout. Once you install and open a VPN client. Press it again and it opens up a new page for the VPN config.
Example of configuration as it is attached. But it differs depending on the configuration of your vpn server.
Once you create and save this profile. Your FCP file is stored.
Please assess whether the information provided is useful.

Hello everyone, I need help in a vpn configuration, this is the problem that I need nat all vpn traffic because I net to put into place a vpn but I already have another vpn with the same network, so that overlap with the new one, then how I can nat overlaps all traffic to another network in order to avoid the network?.
Please I really need help
Thank you
You say that the 192.168.1.100 is able to go through the tunnel and the internet now?
Try to add another...

(2) with Split tunnel with simultaneous assess internal LAN and Internet on the outside.
But I was not able to make the tradiotional model Hairpinng to work in this scenario.
I followed every possible suggestions made on this subject in many topics of Discussion but still no luck. Can someone help me here please?

Adding dynamic NAT for 192.168.150.0/24 on the external interface works, or works the sysopt connection permit VPN
Please tell what to do here, to pin all of the traffic Internet from VPN Clients.
That is, that I need clients connected via VPN tunnel, when connected to the internet, should have their addresses IP NAT'ted against the address of outside internet2 network 2.2.2.2 interface, as it happens for the customers of Campus (172.16.0.0/16)
I am well aware of all involved in here, so please be elaborative in your answers. Please let me know if you need more information about this configuration to respond to my request.
Thank you & best regards
MAXS
Hello
If possible, I'd like to see that a TCP connection attempt (e.g. http://www.google.com) in the ASDM logging of the VPN Client when you set up the dynamic NAT for the VPN Pool also.
I'll try also the command "packet - trace" on the SAA, while the VPN Client is connected to the ASA.
The command format is
packet-tracer intput tcp
That should tell what the SAA for this kind of package entering its "input" interface
Still can not see something wrong with the configuration (other than the statement of "nat" missing Dynamics PAT)

Please help me to set the ACL and capture for remote access VPN traffic.
To see the amount of traffic flows from this IP Source address.

Destination: any
That's what I've done does not

Hello
If you have configured capture with this access list, you filter all TCP traffic, so you will not be able to see the UDP or ICMP traffic too, I would recommend using the ACL, although only with intellectual property:

Capture interface outside access, VPN CAP_VPN-list
Then with:
See the capture of CAP_VPN
You will be able to see the packet capture on the SAA, you can export the capture of a sniffer of packages as follows:

ASA encrypt interesting VPN traffic
Hello everybody out there using ASA.
I had a few IPSEC VPN tunnels between the company's central site and remote sites.
Two dsl lines were connected to the ASA, one for VPN traffic and the other for the internet.
The default gateway has been configured online internet, some static while insured roads as traffic to the sites of the company was sent through the other line.
A few days ago we changed the configuration of ASA to use only a single dsl connection, then the line serving the internet has been cut, while the other will become the gateway default and static routes have been removed.
The VPN connections instant stopped working and trying to send packets to the remote lan, it seems that ASA will not recognize that the traffic is encrypted. Obviousely we checked cryptomap, acl, ecc, but we find no problem... do you have any suggestions?
Thanks in advance,
Matt

Hello
Your exit the ASA must be encrypting the traffic between XNetwork and YNetwork.
If the ASA does not encrypt this traffic, it could be because there is a problem with the NAT configuration.
When the ASA receives a packet, it must first check if there are ACLs that allows traffic, passes through the inspection engine and check that the associated NAT. For example, if the package is coordinated, then the private IP encryption will never take place.
Could ensure you that packets from the XNetwork are really reach the ASA, the NAT rule is correct and you may be looking for "debugging cry isa 127" and "scream ips 127" debug to check for errors of incompatibility.
In addition, what is the condition of the tunnel trying to communicate: "sh cry isa his"

Does site to Site VPN traffic.
Hello
I had a problem with my connection to my supplier, and we can't figure it out for the life of us. We have the tunnel upward, we simply cannot ping either side of it. (as you can tell from the moment where the position, I am at a loss).
The goal is for our site to pass all traffic via the seller, so they can go out route to the internet for the rest of their network.
As I said, the tunnel is just, does not seem to be passsing no matter what traffic, or at least real traffic, I think the keep alives pass.
Hello
Some comments on configurations
Your configurations of sites on a quick glance seems fine. You have configured NAT0 for all traffic and you have set up all the traffic on the local network to connect VPN L2L.
The seller site configurations seems a little weird. Lets start with the routing. It has a route for network 10.0.0.0/8 and 10.4.0.0/16 pointing to the IP address 10.4.250.49 behind the interface 'inner' that CANNOT be the right gateway IP address as the IP 'internal' interfaces is 10.4.253.66/30, so the roads to my knowledge are useless. (IP address of the next hop must be from a directly connected network)
These are the roads
Route inside 10.0.0.0 255.0.0.0 10.4.250.49 1
Route inside 10.4.0.0 255.255.0.0 10.4.250.49 1
It's the 'inside' interface
interface GigabitEthernet0/1
No tap
Speed 1000
full duplex
nameif inside
security-level 100
IP 10.4.253.66 255.255.255.252
So with the configuration above it needs impossible even for traffic to the front between the local networks of the two sites.
If your goal is also to have passed your site outside of the site and outside traffic to the Internet through the ASA of the seller then its lack of certain configurations.
You should be at least
Global 1 interface (outside)
Since there are only "nat" statement currently sets the addresses of source for translations, but there is no "global" setting the actual address of the NAT/PAT.
The ASA of the Site of the seller is also the command lack
permit same-security-traffic intra-interface
That would allow the traffic coming through the "outside" interface (from your site through the VPN) and go through the 'outside' (your topic traffic to Internet)

VPN needs access to all external internal vpn traffic traffic all in tunnel
Hello
Could someone help me find the problem?
I am ASA configuration as firewall + vpn server, essentially outside of the device's access T1 (there are two VLANS in inside via an iptables, outside of iptables is on the same vlan as insdie of ASA (192.168.5.1 and 192.168.5.2).) VPN users are authenticated via authentication 2 factors (SDI, ip is 192.168.5.5) and get the ACL by local database. pool of VPN is 192.168.6.1 - 192.168.6.15. pool of VPN is coordinated to the external IP address
trying to access a remote host A from the host a is open for the IP and one specific Protocol. all vpn traffic are in the tunnel. the VPN user can connected and ACL vpnuser1_ONLY not working does not as expected.
Here is the part of configuration:

Thank you

First of all, you can set "no nat-control" because once you have relieved of NAT, 'no nat-control' becomes disable anyway. 'No nat-control' is useful if you have no statement of NAT at all on the interface.
Second, if you can't access the outside inside which is because you must configure the NAT exemption. Not sure if you have configured it.
Here's the command:
access-list allowed sheep ip 192.168.1.0 255.255.255.0 192.168.6.0 255.255.255.0
NAT (inside) 0 access-list sheep
You can then add all other subnets that are internal to the ACL sheep if you need VPN access.
Finally, for the error message deny on access-group "OUTSIDE", you would need check if you have configured "sysopt connection VPN-enabled'. If it is disabled, it will also check the "OUTSIDE" interface for VPN traffic.

VPN traffic via a secondary access provider
Hello world
I have been asked by a client to implement this topology:
where:
ISP 1 is used as primary internet connection.
2 ISP will be used to connect remote users by IPsec VPN.
Currently, I'm not looking for the Active/Backup feature, I need to know if I can use both ISP connections (as I've written before) an ISP for the Internet company and the other for the user remote access VPN.
I read some post where, said, it's possible, but I want to be sure.
Kind regards
Jose
ASA must add the static route in the routing table automatically when the VPN client is connected. So, in general, you don't need to do anything. But if not, you can just manually configure who will forward a VPN client IP packet to ISP2.
With respect to NAT, in general, VPN traffic must ignore the NAT. You can use "nat (inside_interface_name) 0-list of access ' with an ACL that define the vpn traffic to do so.

7.2 ASA5520 - filters VPN traffic
Hi all,
I would like to know how can I filter out VPN traffic with a list of access, by using the source address and port of destination as filters.
I tried with "no sysopt permit vpn connection" but it is to filter the traffic through the VPN tunnel and I want to filter the host which can establish the VPN tunnel.
I did it in a router with this access list:
Note access-list 101 VPN
access-list 101 permit ahp host x.x.x.x everything
access-list 101 permit esp host x.x.x.x any newspaper
access-list 101 permit host x.x.x.x esp all
access-list 101 permit udp host x.x.x.x any eq isakmp
access-list 101 permit udp host x.x.x.x any eq non500-isakmp
But I tried the same thing in the ASA and does not work, I think it's because the ASA does not apply the access list for VPN traffic.
Sincerely, Fernando.
Fernando
You can disable it with "no crypto isakmp are outside", but then even if you apply an acl to the outside which allows all IP, ESP, AH it still does not allow an IPSEC connection.
So for the moment I see no way to do this without using an acl on your router upstream.
I'll do a reading just in case I missed something.

VPN traffic through incoming port
On my ASA 5510 I want for the VPN clients can connect on the outer harbour and have their internet traffic directed back on that same port, with the internal traffic inside port. Is this possible? If so, how does do this?
Will be transmitted traffic VPN based on the routing table after out of the tunnel.
If you do not want to let Internet traffic to turn on the external interface, you must add
-permit same-security-traffic intra-interface
-make the Association NAT change such as
Global interface 4 (external)
NAT (outside) 4
