Redirect VPN traffic to a single ip LAN

Hello world

I have this problem: my company needs profiles of access for VPN connections because different users have reach the different internal host.

To do this, I have configured a group policy and assigned a standard ACLs that allow only a single ip address in my local network.

But when I opened the tunnel, I can't reach this ip address.

How can I do to achieve this?

Cisco ipsec Vpn connects but cannot communicate with lan

I have a version of cisco 1921 15.2 (4) M3 I install vpn ipsec and may have customers to connect but cannot ping anything inside. A glimpse of what could be wrong with my config would be greatly appreciated. I posted the configuration as well as running a few outings of ipsec. I also tried with multiple operating systems using cisco vpn client and shrewsoft. I am able to connect to the other VPN ipsec running 1921 both of these computers by using a client.

Thanks for any assistance

In your acl, nat, you will need to refuse your VPN traffic before you allow the subnet at all. Just put all the declarations of refusal before the declarations of licence.

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"

Federico.

Remote access VPN users unable to see local lan or internet

We implement an ASA5510. Now our users can connect to the vpn but cannot access the internal Lan or internet.

Here is the config. Any help or idea would be greatly appreciated. Thank you

Hello

A couple of things set this:

-crypto isakmp nat-traversal 20

-management-access inside

Can you run a packet tracer and attach it here, to see what are the phases that crosses the package.

David Castro,

Concerning

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?

Offbox activate PRSM CX Redirection of traffic

Hello

IV ' e had installed (Offbox) 9.3 PRSM.

I imported a pair of tilting ASA5585-X - each with a (big) inside CX module

How the hell you set a policy of redirection of traffic to send traffic through the modules CX!

IM pulling my hair out, if you add the tab 'traffic redirection' is said "no element is found."

Im not surprised, its not allowed - I want to put on with PRSM!

This software is terrible!

Pete

Hi Pete. A break on what hair you have left and check the CX Module Quick Start Guide for the ASDM method.

Short answer is that you use a rule of service strategy (policy-map). The CLI so that it is further explained in the User Guide for the ASA CX.

You can set this bit on the PRSM ASA technically but you would have to first import and manage the SAA itself (not just the modules CX). I have not tried this method as PRSM is a bad tool to manage an ASA. Same Cisco directs you little far this option in their documentation

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 between 2 routers Cisco 1841 (LAN to LAN)

Hello

I need to connect two offices (two different LAN) using routers cisco 1841 at both ends.

Currently the two cisco router are in working condition and refer the internet LAN clients. (making the NAT).

Can someone please tell us what is the easiest way to set up a VPN between two sites, so that LAN users to an office to access mail servers electronic/request to the office LAN.

I understand that I need IPSec Site to Site VPN (I think).

Anyonce can you please advise.

Kind regards.

Yes, you need a VPN site-to site. Start with this link which gives a number of examples to set up a VPN S2S between 2 routers Cisco.

Capture packets for VPN traffic

Hi team,

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.

Source: Remote VPN IP (syringe) 10.10.10.10 access

Destination: any

That's what I've done does not

extended VPN permit tcp host 10.10.10.10 access list all

interface captures CAP_VPN VPN access to OUTSIDE gross-list data type

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:

list of allowed extended VPN ip host 10.10.10.10 access everything

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:

https:// /capture//pcap capname--> CAP

For more details of capture you can find it on this link

Let me know if you could get the information that you were trying to achieve.

Please Don t forget to rate and score as correct the helpful post!

David Castro,

NAT on the VPN traffic

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...

IP nat inside source static 192.168.1.101 10.10.44.101 map route VPN

for example.

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:

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.

Return VPN traffic flows do not on the tunnel

Hello.

I tried to find something on the internet for this problem, but am fails miserably. I guess I don't really understand how the cisco decides on the road.

In any case, I have a Cisco 837 which I use for internet access and to which I would like to be able to complete a VPN on. When I vpn (using vpnc in a Solaris box as it happens which is connected to the cisco ethernet interface), I can establish a VPN and when I ping a host on the inside, I see this package ping happen, however, the return package, the cisco 837 is trying to send via the public internet facing interface Dialer1 without encryption. I can't work for the life of me why.

(Also note: I can also establish a tunnel to the public internet, but again, I don't can not all traffic through the tunnel.) I guess I'm having the same problem, IE back of packages are not going where it should be, but I do know that for some, on the host being ping well, I can see the ping arriving packets and the host responds with a response to ICMP echo).

Hi Eric,.

(Sorry for the late reply - needed some holidays)

So I see that you have a few steps away now. I think that there are 2 things we can try:

1)

I guess you have provided that:

IP nat inside source overload map route SDM_RMAP_1 interface Dialer1

Since the routemap refers to ACL 100 to define the traffic to be translated, we can exclude traffic that initiates the router:

Access-list 100 category SDM_ACL = 2 Note

access-list 100 deny ip 123.12.12.185 host everything
access-list 100 deny ip any 10.10.148.0 0.0.0.255
access ip-list 100 permit a whole

Which should prevent the source udp 4500 to 1029 changing port

OR

2)

If you prefer to use a different ip address for VPN,

Then, you can use a loop like this:

loopback interface 0

123.12.12.187 the IP 255.255.255.255

No tap

map SDM_CMAP_1 crypto local-address loopback 0

I don't think you should apply card encryption to the loopback interface, but it's been a while since I have configured something like that, so if you have problems first try and if still does not get the crypto debugs new (isakmp + ipsec on the vpn, nat router on the router of the client package).

SSL VPN traffic

Hello

I have configured the client SSL VPN on SAA. I'm able to establish SSL VPN with the ASA and obtaining the IP address of subnet defined (CorporateVPN 172.16.0.100 - 172.16.0.110). But when I try to ping inside the property intellectual treats which is 172.16.0.1 and other machine in the range LAN getting loss of packets to the remote machine.

What could be the problem?

Yes, 'inside access management' is only to manage/ping of the SAA within the interface. Without this command, they would still be able to access the internal network. This command is only used to manage the SAA within the interface itself.

Newbie Help Needed: Cisco 1941 router site to site VPN traffic routing issue

Hello

Please I need help with a VPN site-to site, I installed a router Cisco 1941 and a VPN concentrator based on Linux (Sophos UTM).

The VPN is established between them, but I can't say the cisco router to send and receive traffic through the tunnel.

Please, what missing am me?

sheep allowed 10 route map

corresponds to the IP 110

The parts of the configuration you posted seem better than earlier versions of the config. The initial problem was that traffic was not in the VPN tunnel. That works now?

Here are the things I see in your config

I don't understand the relationship of these 2 static routes by default. It identifies completely the next hop and a mask the bytes of Middleweight of the next hop. Sort of, it seems that they might be the same. But if they were the same, I don't understand why they both make their appearance in the config. Can provide you details?

IP route 0.0.0.0 0.0.0.0 62.X.X... 121

IP route 0.0.0.0 0.0.0.0 62.172.32.121

This static route implies that there is another network (10.2.0/24) connected through the LAN. But there is no other reference to it and especially not for this translation. So I wonder how it works?

IP route 10.2.0.0 255.255.255.0 192.168.20.2

In this pair of static routes, the second route is a specific subnet more and would be included in the first and routes for the next of the same break. So I wonder why they are there are. There is not necessarily a problem, but is perhaps something that could be cleaned up.

IP route 172.17.0.0 255.255.0.0 Tunnel20

IP route 172.17.2.0 255.255.255.0 Tunnel20

And these 2 static routes are similar. The second is a more precise indication and would be included in the first. And it is referred to the same next hop. So why have the other?

IP route 172.18.0.0 255.255.0.0 Tunnel20

IP route 172.18.0.0 Tunnel20 255.255.255.252
