VPN IPSEC on Metro-Elba

Hi all

I have a small question. Is it possible to run L2L IPSEC VPN via a subway-E connection? It's not supposed to do something like that with Metro-E but this connection is with a partner so at both ends, firewall is in place. With port forwading, NATting, etc, etc, I came across problems of providing additional services because of it. I hope that IPSEC VPN L2L at both ends will solve this problem once and for all. The only question is of course in fact that a metro-E is just an ethernet connection and not really difference in setting up a VPN IPSEC of L2L via internet.

Thank you for your help.

Eric,

Yes, connection L2L IPSEC VPN Tunnel Over Metro-E should work perfectly. You might meet in the treatment of air issues and the flow on the VPN server but it should be good.

Kind regards

Blocks VIRTUAL local network access to a tunnel VPN IPSec on WRV200?

I have two identical WRV200 wireless routers which are connected by a VPN IPSec tunnel. This goes to my LAN LAN of my parents. Everything works well.

But I also have my WRV200 configured for two VLANS. Vlan1 for my network and secure wireless access. VLAN2 for a WiFi not secure for customers.

My problem is that my guest on VLAN2 slips through the VPN devices and access on LAN of my parents. I'm looking for a way to block to do this.

I use the version of the software on the two routers (v1.0.39).

For what it's worth, I know that my receive an IP address in the range 192.168.x.101 DHCP - 199. I could assign a different range if that helps. I thought that I could block this beach on the remote router firewall, but I see there is blocking a single IP address at the time, maximum of 8. Am I missing something?

Or could I put something weird in the routing tables somewhere to get the IPs guest out of lala land?

Any suggestions are appreciated. I can't be the only one in this boat.

Try to check local and remote, vpn under safe group settings if you change the ip address range subnet. Don't include the range of ip addresses of the computers wireless comments so that it will not pass through the vpn tunnel. If there is no ip range option, you must to the subnet of the network in order to control the ip address you want to allow on the vpn tunnel.

need help with VPN IPSEC with RV042

https://supportforums.Cisco.com/docs/doc-30883

I enjoy any support for a trial with RV042 VPN IPSec game please.

Thanks in advance.

Hi Bay, if you use a Windows computer, you can use QuickVPN. The only thing to note is the router that you have as the gateway to the RV042. You must define a port forward for all IPsec services be able to overcome the problems with the NAT device.

RV042 configuration is easy, create a name of user and password and that's it. The problem/challenge will get your NAT connection to allow VPN pass.

Cisco's VPN IPSec help please

Hi all

I have 3 sites, the main site has a cisco firewall mikrotik router.

There is a vpn ipsec existing between the cisco router and another router cisco on the site of the 2nd and it works well.

Now, I've added an another vpn between a 3rd site and main site. The router on the 3rd site is a mikrotik firewall.

I had the vpn on the main site and the 3rd site where the mikrotik firewall is and it worked well.

then for some reason, the vpn with the 3rd site has failed and I could not get it working again.

When looking for answers, I see that the vpn for the 3rd site States the following:

#pkts program: 46, #pkts encrypt: 46, #pkts digest: 46
#pkts decaps: 0, #pkts decrypt: 0, #pkts check: 0

It seems that no traffic is coming back to the cisco

I also found the following output below to diagnose the problem.

It seems that there is communication, but if I read this right, it looks like the cisco established a new number but the other end is not the new number

Comparing encrypt of 46 to 47436 counters, it seems that router is ecncrypting the traffic, but we do not get any interesting traffic on the remote side.

Most likely, you might want to check on the remote site, if you see counters increment in parallel decryption and encryption of the counters are incrementing or not.

On the router IOS, if are incrementing counters encrypt, and confirm that you have not any tunnel existing before the router can be seen same proxy IDs, which is already negotiated with other peer.

Finally, please make sure that the ESP, 50 protocol traffic is not blocked in transit.
I hope this helps.

Here are a few suggestions:

change this:

radius of group AAA authorization network groupauthor

for this

AAA authorization groupauthor LAN

(unless you use the group permission for your radius server you need local)

Choose either on ISAKMP profiles and if you decide to go with and then get rid of these lines:

map clientmap client to authenticate crypto list userauthen

card crypto clientmap isakmp authorization list groupauthor

client configuration address map clientmap crypto answer

AND change the following items on your profile isakmp:

Crypto isakmp VPNclient profile

ISAKMP authorization list groupauthor

Also if you'll use a list for user authentication, I advise you to avoid using the default list so go ahead and change it too much under the isakmp profile

client authentication list userauthen.

If you do not use isakmp profiles change the following:

No crypto isakmp VPNclient profile

Crypto-map dynamic dynmap 10

No VPNclient set isakmp-profile

GRE tunnels will not come on VPN IPsec/GRE

Hi all

We have 400 + remote sites that connect to our central location (and a backup site) using Cisco routers with vpn IPSec/GRE tunnels. We use a basic model for the creation of tunnels, so there is very little chance of a bad configuration on each router. Remote sites use Cisco 831 s, central sites use Cisco 2821 s. There is a site where the tunnels WILL refuse just to come.

Routers are able to ping their public IP addresses, so it is not a routing problem, but gre endpoints cannot ping. There is no NATing involved, two routers directly accessing the Internet. The assorded display orders seem to indicate that the SAs are properly built, but newspapers, it seems that last part just don't is finished, and the GRE tunnels come not only upward.

The attached log file, it seems that both its IPSEC & ISAKMP are created @ 00:25:14, then QM_PHASE2 end @ 00:25:15.

I don't have the remote router log file, and is very long, so I joined her. Before that I captured the log file, I enabled debugging ipsec & isakmp and immediately authorized the SAs.

VPN ipsec Cisco 877 <>- iphone

Hi, I'm trying implement the vpn ipsec between my cisco 877 and his iphone/cisco vpn client. First of all, what is the difference between remote access vpn and vpn installation easy? The phase 1 and the phase2 are completed but I don't have much traffic between peers.

Maybe I missed something conf? Should I add the roadmap with acl 101?

Here is the configuration of isakmp/ipsec.

no access list 101
Note access-list 101 * ACL sheep *.
access-list 101 deny ip 10.0.77.0 0.0.0.255 192.168.69.0 0.0.0.255
access-list 101 permit ip 10.0.77.0 0.0.0.255 any

Should I apply this acl 101 loopback? Ex:

overload of IP nat inside source list 101 interface Loopback0

Should I apply an acl to permit as access-list 169 allow ip 192.168.69.0 0.0.0.255 any in my Dialer interface 0?

Other tips? Best regards.

Hi Alessandro,.

The access tunnel split list is great!

If you are NAT on public and private interface that is ip nat inside and ip nat outside etc.

You must add the command ip nat inside source list 101 interface Dialer0 overload

+++++++++++++++++++++++++++++++++++++++

Or you can create a new roadmap

new route map permit 10

ACL #match 101

command: ip nat inside the interface Dialer0 overload route map

Thank you

VPN/IPSec-L2L - Question?

Hello!

Recently, I was doing some troubleshooting on a connection VPN/IPSec Lan-to-Lan between a Cisco PIX515E and a Linux firewall. My question concerns the configuration and is not the problem itself.

Traffic interesting (encrypted traffic) defined and configured the LAN of PIX (inside) and the distance public IP? Which means that the Peer IKE and the interesting remote control LAN/IP are the same... and it works!

Any ideas?

Thank you

JP

As long as you source the package from the local network of Pix to remote public IP, the tunnel will work well and works :-)

So, if you really look at the fluidity of the traffic, you're sourcing traffic from Pix LAN intended to public IP remote that corresponds to the defined access list. Thus, the pix knows he has encrypt traffic and now seeks the cryptographic endpoint points (pix outside IP public IP remotely) and sends the encrypted packets. So, this configuration works perfectly.

In fact, Pix will not allow Telnet the external of the pix interface unless the traffic is through an IPSEC Tunnel and it was one of the establishment who gave a telnet access to the external interface of the Pix, it's LAN to the public IP of Pix through an IPSEC Tunnel.

Kind regards

VPN ipsec and port 500

Hello world

I connected connection VPN IPSEC.

Connection works fine.

Here's the Setup program

PC---R1---R2--R3---ISP---ASA

I check on R3

The R3 CBAC is configured.

R3 # sh ip inspect sessions | 96.51.x.x Inc.
65719DB4 (192.168.98.6:59936)-online (96.51.x.x:4500) SIS_OPEN udp session

What vpn ipsec connection is established, it shows that it is plugged into the port 4500 not 500?

What is default behavior?

Initially when he formed theVPN connection it showed both udp, ports 500 and 4500.

Concerning

MAhesh

It has NAT/PAT between R3 and ASA. like address (192.168.98.6) private IP allows you to configure the ipsec session. IKE detects NAT/PAT exist in NAT - D payload. IKE uses UDP 4500 to negotiate ISAKMP rather than UDP 500. Subsequently, the ESP traffic is also encapsulated in UDP 4500, in this way it can cross the NAT/PAT safely.

If this behavior is expected.

IOS router VPN Client (easy VPN) IPsec with Anyconnect

Hello

I would like to set up my router IOS IPsec VPN Client and connect with any connect.
Is it possible to configure an IPSec and SSL VPN Client on IOS router? I use for example a 1841.

It would be perfect to give the user the choice of SSL or IPSec protocol. And the user needs that the Anyconnect Client.

I think it's possible with a Cisco ASA. But I can also do this with an IOS router?

Please let me know how if this is possible.

Also is it true that the IOS routers are not affected to hear bug bleed? SSL VPN and SSL VPN with Anyconnect page is also save?

http://Tools.Cisco.com/Security/Center/content/CiscoSecurityAdvisory/CIS...

But I am in any way interested in using IPSec and SSL VPN on a router IOS...

It's true - CCP does not yet offer the options to configure a VPN IPsec with IKEv2.

The configuration guide (here) offers detailed advice and includes examples of configuration.

QNS vpn IPsec

Hello

I have 2 questions about vpn IPsec

I have an asa, vpn ipsec (l2l) running on a remote site with 192.168.0.0/24 network

1 > I can ping 192.168.0.1 but not 192.168.0.111. I had observed "Recv errors" whenever I have ping to 192.168.0.111.

I had observed recevied errors of "crypto ipsec to show his" exit; but not because the tunnel to reconnect (after timeout) and w/o any changes made to the configuration.

What could be the cause and how can I fix just in case where the returned errors? I can't find much info on "recv errors."

2 > I understand there are 2 acl required for a vpn ipsec typical; 1 for no NAT, 1 correspondence address card crypto

can I implement an acl to allow tcp 3389 only from the remote network on my local network on the asa?

Thank you

cash

Salvation of cash,

There is not a lot we can do here in what concerns this isuse.

You can talk to your service provider and see if they do not modify the packets somehow.

Also ask them to check for any problem on the circuit.

See you soon,.

Setup for use with Cisco Anyconnect VPN IPsec

So, I had trouble setting up VPN on our ASA 5510. I would use IPsec VPN so that we don't have to worry about licensing issues, but what I have read you can do with and always use Cisco Anyconnect. My knowledge on how to set up VPN especially in iOS version 8.4 is limited, so I've been using a combination of command line and ASDM.

I am finally able to connect from a remote location, but once I log in, nothing else works. What I've read, you can use IPsec for client-to-lan connections. I use a pre-shared for this. Documentation is limited on what should happen after have connected you? Shouldn't be able to local access on the vpn connection computers? I'm trying to implement work. If I have VPN from home, should not be able to access all of the resources at work? According to me, because I used the command-line as ASDM I confused some of the configuration. In addition, I think that some of the default policies are confused me too. So I probably need a lot of help. Here is my current setup with the changed IP address and other things that are not related to deleted VPN.

NOTE: We are still testing this ASA and is not in production.

Any help you can give me is greatly appreciated.

Statistical accounting of user

I would recommend buy AnyConnect Essentials. The cost of the license is nominal - list of US $150 for the 5510. (piece number L-ASA-AC-E-5510 =)

Meawwhile you can use the Cisco VPN client inherited with IKEv1 IPSec remote access VPN using profiles *.pcf.

I believe you can also use the client Anyconnect client SSL or DTLS transport access remotely (non-IPsec) without having to buy the license Anyconnect Essentials for your ASA focus.

As an aside, note that if you want to use AnyConnect Mobile (e.g. for iPhone, iPad, Android, Blackberry etc.clients) you will also get the additional license for it (L-ASA-AC-M-5510 =, also price US $150)

ASA ASA from Site to Site VPN IPSec Tunnel

Any help would be greatly appreciated...

I have two devices Cisco ASA with a Site for the configuration of the tunnel VPN IPSec Site as follows: -.

Site #1 - Cisco ASA running version 8.2 (1) with an internal range of 10.0.0.x/24

Site #2 - Cisco ASA running version 8.2 (1) with an internal range of 10.1.1.x/24

Site #1 is simple and has a dynamic NAT rule which translates all of the inside and the outside (public IP) of the SAA.

Internet access works very well in all workstations of this site. A static route is configured to redirect all traffic to a public router upstream.

Site #2 is slightly more complicated; the Cisco ASA is configured with 10.1.1.254/24 as its interior IP address and 10.1.2.254/24 as its external IP address. A dynamic NAT rule is configured to translate everything inside as the 10.1.2.254 (outside) address of the ASA. A default static route is then configured to redirect all traffic to a Draytek device on 10.1.2.253. This device then performs its own private Public NAT. Again the Internet works fine all hosts inside the Cisco ASA (10.1.1.x)

The IPSec tunnel is created with the networks local and remote endpoint as above (10.0.0.x/24) and (10.1.1.x/24). The Draytek at the Site #2 device is configured with a form of DMZ that allows essentially ALL traffic toward the front directly on the external interface of the ASA (10.1.2.254). The Phase 1 and Phase 2 negotiation of the tunnel ends correctly, and the tunnel is formed without any problem. However, all traffic passing on networks ICMP does not end and the Syslog reports the following-

Site #1-

6 January 19, 2011 15:27:21 302020 ZEFF-SB-01_LAN 1 10.1.1.51 0 Built of outbound ICMP connection for faddr 10.1.1.51/0 gaddr ZEFF-SB-01_LAN/1 laddr ZEFF-SB-01_LAN/1

6 January 19, 2011 15:27:23 302021 10.1.1.51 0 ZEFF-SB-01_LAN 1 Connection of ICMP disassembly for faddr 10.1.1.51/0 gaddr ZEFF-SB-01_LAN/1 laddr ZEFF-SB-01_LAN/1

Site #2-

6 January 19, 2011 15:24:47 302020 10.1.1.51 0 10.0.0.30 1 Built of outbound ICMP connection for faddr gaddr laddr 10.1.1.51/0 10.1.1.51/0 10.0.0.30/1

6 January 19, 2011 15:24:49 302021 10.0.0.30 1 10.1.1.51 0 Connection of disassembly for faddr gaddr laddr 10.1.1.51/0 10.1.1.51/0 10.0.0.30/1 ICMP

It's the same for any form of traffic passing over the tunnel. The ACL is configured to allow segments of LAN out to any destination. At this point, I left scratching my head, as my original theory was to blame the Draytek, but after reading the documentation given to the DMZ host configuration, it appears this parameter is configured all traffic is simply forwarded to the IP address (in this case, the Cisco ASA interface outside).

Anyone can shed light on a possible cause of this problem?

Thank you

Nick

did you bypass the vpn traffic between 10.0.0 and 10.1.1 to be NAT - ed on the two ASA?

Please provide the following information

-set up the tunnel

-show the isa cry his

-show the ipsec cry his

-ping of the site 1 site 2 via tunnel

-capture "crypto ipsec to show his" once again

-ping from site 2 to 1 by the tunnel of the site

-capture "crypto ipsec to show his" once again

-two ASA configuration.

Site-to-Site VPN IPSEC falls intermittently

Site-to-Site VPN IPSEC falls intermittently

I am currently having a problem with a VPN from Site to Site traffic not only not intermittently. When the problem occurs, I can't Ping the remote site to the AC Site. But I can solve the problem by Pinging from HQ at the Remote Site. My network is currently configured as follows

-------HQ------

7.0 (4) version of pix 515 with card Ethernet 4 ports.

Outside of the interface connected to the Broadband DSL link.

Outside2 Interface connected to the second link DSL broadband

-Distance-

I have 4 Remote Sites. 2 sites connect you to each connection to wide band at HQ to spread the load to HQ

6.3 (5) pix 501 version

# The problem #.

All VPN establishes successfully to the HQ Pix

Intermittently, a remote site will report that they cannot connect to servers/services in the HQ. When I do a show crypto ipsec's and see the crypto isakmp his headquarters there is no entry for the remote site. However when I do the same on the remote site there is an entry for the HQ. With debugging on the remote site pix I try to ping from a pc to the HQ server and I get the following (see below). If I do a "ipsec Isakmp security association claire crypto ' and ' clear crypto ipsec his ' on the pix of remote site, then I can successfully ping all servers in headquarters.

This problem seems to have taken place only when I upgraded the pix of a 501 to 515 and added another 2 remote sites and a second broadband, as described above. I'm afraid that there is a problem with software version 7 Pix. Any advice would be greatly appreciated.

Can force you the ISAKMP Keepalive, value from IPSec Security Association idle time and on the other. The problem should be solved

ISAKMP crypto keepalive 30

Crypto ipsec security association temps_inactivite 60

Let me know if it helps

Site to Site VPN IPsec IPv6 on issue of routers-Tunnel

Hi, I am experiencing a problem can any one address the question below and let me know the solution. I have two routers and try to build "Site to Site VPN IPsec IPv6". I followed orders from Cisco and community document but when I apply my profile of ipsec for tunnel interfaces, that the tunnel is down.

Ali,

VTI tunnels are meant to be broken when there is no active negotiated spinnakers.

The tunnel will go towards up/face upwards when there is a means of transport of packages - i.e. the SPIs are present.

You can control the order spinnakers 'show peer's crypto ipsec '.

For debugging:

Debug crypto isa

Debug crypto ipsec
