Impossible to establish L2L ipsec VPN

• l2l ipsec vpn - problem XAUTH need-based policy

  Hello

  I have a problem that I see a few solutions but they do not work.

  I have a p2p IPSec vpn, which worked until I added access remote VPN configuration (which works perfectly).

  According to the documents, I used isakmp policy allowing mixed tunnels. Now, whenever I try to send traffic through the l2l link I get the following debugging results telling me that the remote router is demanding XAUTH.

  It is a bit of a breakfast dogs because I'm at the time of implementation of policies.

  I managed to block xauth before I used policy by adding no_xauth the end of my speech key but I can't work out how to add this using the strategy.

  I'm something simple Paris that I missed.

  Thanks for your help!

  Hi Bruno.

  Thanks for the brief explanation.

  What crypto map is applied on the external interface?

  I think the "crypto isakmp profile" solution is the best way and they seem to be ok, however, we must remember that you cannot have a single card encryption by interface, so you should have something like this:

  1 - crypto dynamic-map outside_dynamic 10

  game of transformation-ESP-AES-SHA

  2-outside_map 10 ipsec-isakmp crypto map

  the value of xxxx.xxxx.xxxx.xxxx peer

  Map 3-crypto outside_map 65535-isakmp ipsec dynamic outside_dynamic

  4-interface f0/0

  outside_map card crypto

  * I'm not configure all of the cryptographic configuration, I wanted to give you a better idea.

  Please correct your configuration to accommodate one card encryption.

  Just to add more information on isakmp profiles:

  Let me know.

  Thank you.

• L2l IPSec VPN blocks SQL (ASA v8.4)

  Good evening everyone,

  I have an ASA 5510 8.4 (2) which has an IPSec VPN site to a 3rd party who run a form any checkpoint running.  VPN establishes and allows to access a server in our demilitarized zone on all the ports that we tested (so far HTTP, FTP, SSL, RDP), with the exception of SQL that does not even reach the server.  I've got Wireshark running on the DMZ server and if the 3rd party initiates a conversation of TCP of their server on any of the ports on the server I see all desired packages come with the correct IPs ETC (without NAT takes place through the VPN), but when an ODBC client attempts to query the SQL Server on our DMZ zone packets do not reach the level of the server.  What I see is the number of bytes of RX on the VPN increases whenever the query is run, but certainly not arriving on the SQL Server.

  Also if I come back to the ASA to the old PIX, it replaced with the same VPN configuration but on version 7.x, then it works fine.

  While I find some time to clean up the config this weekend, I have ideas.

  Thank you very much

  Simon.

  Hi Simon,.

  If you look at the options sys in the ASDM he advises that you still need ACL for traffic. As I understand it, in the old days, when you were in as you pointed out. If you set the ports in this group then Yes, it's a whole and potentially your only protection is the NAT or his absence.

  I would like to add an another ACE to the external interface, which allows the source to you DMZ host (see below)

  Object-group service GROUP SQL-tcp PORTS

  EQ port 1433 object

  EQ object Port 1434

  I only give your router cisco 892 because there is nothnig much to change on linksys wrv210 router.

  Hope someone can help me. See you soon

  You can run a "ip inspect log drop-pkt" and see if get you any what FW-DROP session corresponding to the traffic you send Linksys to the main site. Zone based firewall could be blocking traffic initiated from outside to inside.

• L2l IPSec VPN 3000 and PIX 501

  Hello

  I have a remote site that has a broadband internet connection and uses a PIX 501.  We wanted to connect them with our main office using our VPN 3000 via VPN site-to-site.

  I followed the following documentation:

  http://www.Cisco.com/en/us/products/HW/vpndevc/ps2284/products_configuration_example09186a00800949d2.shtml#tshoot

  However the L2L session does not appear on the hub when I check the active sessions.

  The network diagram, as well as the PIX config and the screenshots of the VPN configuration for the IPSec-L2L tunnel is attached.

  Any help or advice are appreciated.

  I just noticed that the PIX firewall, the phase 1 paramateres are not configured. You must configure the same PASE 1 and phase 2 settings on both ends of the tunnel.

  For example, on CVPN 3000, you have configured settings Phase 1 as 3DES, pre-shared key etc... We have the same configuration on the PIX firewall too.

  Here is an example of sample config

  http://www.Cisco.com/en/us/products/HW/vpndevc/ps2284/products_configuration_example09186a00800949d2.shtml

  I hope this helps!

• several L2L ipsec VPN to the same destination (ip address)

  Hi all

  im lookin to establish an a L2L ips multiple tunnels (a tunnel for each subnet) of my cisco asa 5510 to the same destination.

  should the cisco asa capable of this?

  How can I do?

  concerning

  You can do this if you want to say-

  Lets say site A - got 3 subnet and Site B has had a.

  In this case, you need to do is to add ACL to crypto.

  Thank you

• Dynamic to static L2L IPSec VPN

  Hello

  I've implemented a dynamic to static IPSec Site to Site VPN between a branch (ship) ASA5505 and headquarters. Now, this solution does not allow HQ initiate the IPsec connection.

  There is a router behind the ASA5505. I heard that if I want to keep the tunnel upward, so that the HQ customers can switch the traffic to remote clients through the tunnel, I would need to run ALS IP icmp probes on the router behind the ASA.

  Could someone explain how to implement it?

  Thanks for your help.

  Frank

  The ICMP probe can be done through any device that is able to do ping, not only of the router.

  The reason is that it is interesting traffic triggers the traffic is encrypted by the vpn tunnel, tunnel will stay up, so you will be able to open the connection to the AC to your remote site.

  Hope that helps.

  But now I want 192.168.55.0/24 access 172.24.0.0/16, some set up but does not work...

  Are there any suggestions?

  Thank you very much

  Hi the split tunnel, you add with the ASA2 network should allow vpn clients send the traffic through the tunnel when they want to reach the remote subnet.

  Can add you this too

  nonat_outside ip access list allow

  NAT (outside) 0-list of access nonat_outside

  Also in the config you have not added the crypto to ASA1 acl entry. who is 192.168.55.0 to 172.24.0.0

  See if that helps

• The poll by IPSEC VPN SNMP

  Hi all

  I am trying to add remote Cisco switches to our Analyzer from Solarwinds network performance and I'm unable to see the community strings of switches behind our Firewall ASA across L2L IPSEC vpn tunnels.

  First of all, I can ping and see all the traffic behind the firewall.   Configuration manager (NCM) works fine, it can download and download configs of the remote switches.  It's just the SNMP which does not seem to talk.  Here are the lines of configuration of the remote switches:

  SNMP-server community * RO

  SNMP-server community * RW

  This configuration works fine on the other our network switches that are not accessible via a VPN tunnel.  Y at - it another line I need to add that pointing to the server from SolarWinds SNMP traffic?

  When I try to add the switch to Solarwinds, he sees the IP perfectly but once I added community strings RO and RW it performs a test fails every time and will not let me continue to add the device.

  Any help would be GREATLY appreciated!  Thank you!

  Matt

  Exit to Windows firewall and check the Antivirus on Solarwinds as well. This may be the origin of the problem (a working time or does not not once). Another possibility (can be), if you have all IPS inline and inspect traffic, this could cause the issue. Check to see if any program/device in the path is kinetically limiting ICMP/SNMP packets #of.

  What version of NPM?

• Easy VPN with IPSec VPN L2L (Site - to - Site) in the same ASA 5505

  Hi Experts,

  We have an ASA 5505 in our environment, and currently two IPSec VPN L2L tunnels are established. But we intend to connect with VPN (Network Extension Mode) easy to another site as a customer. Is it possible to configure easy VPN configurations by keeping the currently active IPSec L2L VPN(Site-to-Site) tunnels? If not possible is there any work around?

  Here's the warning we get then tried to configure the easy VPN Client.

• Impossible to establish a VPN between AG241 and WAG54GP2 tunnel

  Hello

  This is my first post on this forum and I send my best regards to everyone!

  I signed up because I have a problem with establishing a VPN tunnel between an AG241 modem/router and a modem/router WAG54GP2 with wireless and VoIP.

  The scenario is simple: both ends have dynamic IP, so I set up an account with dyndns.org for both routers.

  WAG54GP2 has 192.168.1.1/255.255.255.0 AG241 has 192.168.3.254/255.255.255.0 IP and IP.

  In both routers, I turned block anonymous internet requests, so I can ping both routers.

  This is the configuration of WAG54GP2:

• ASA 8.6 - l2l IPsec tunnel established - not possible to ping

  Hello world

  I have a problem of configuration of the CISCO ASA 5512-x (IOS 8.6).

  The IPsec tunnel is created between ASA and an another non-CISCO router (hereinafter "router"). I can send packets ping from router to ASA, but ASA is NOT able to meet these demands. Sending requests of ASA is also NOT possible.

  I'm trying to interconnect with the network 192.168.2.0/24 (CISCO, interface DMZ) premises and 192.168.3.0/24 (router).

  The CISCO ASA has a static public IP address. The router has a dynamic IP address, so I use the dynamic-map option...

  Do you have an idea that I am wrong? Probably some bad NAT/ACL I suppose, but I could always find something only for 8.4 iOS and not 8.6... Perhaps and no doubt I already missed the configuration with the unwanted controls, but I've tried various things...

  Please, if you have an idea, let me know! Thank you very much!

  Hello

  I've never used "global" option in ACL, but it looks to be the origin of the problem. Cisco doc.

  "The global access rules are defined as a special ACL that is processed for each interface on the device for incoming traffic in the interface. Thus, although the ACL is configured once on the device, it acts as an ACL defined for Management In secondary interface-specific. (Global rules are always in the direction of In, never Out Management). "

  You ACL: access-list extended dmz_acl to any any icmp echo

  For example, when you launch the ASA, there is an echo response from the router on the external interface--> global can block.

  Then to initiate router, the ASA Launches echo-reply being blocked again.

  Try to add permit-response to echo as well.

  In addition, you can use both "inspect icmp" in world politics than the ACL.

  If none does not work, you can run another t-shoot with control packet - trace on SAA.

  I guess that you may need to remove these also

  Crypto-map dynamic IPSecVPNDM 1jeu reverse-road

  card crypto IPSecVPNCM 1-isakmp dynamic ipsec IPSecVPNDM

  And again with the sequence number of 65535 for example instead of 1

  Dynamic crypto map IPSecVPNDM 65535 define ikev1 IPSec transform-set

  Crypto-map dynamic IPSecVPNDM 65535 the value reverse-road

  map of crypto IPSecVPNCM 65535 - isakmp dynamic ipsec IPSecVPNDM

  Then use a different number of VPN L2L sequence. For example, the sequence number indicates where order ASA tries to find a match for a VPN connection. Also, it probably gives this error message because you have dynamic configurations already with this sequence number and try to use the same with VPN L2L configurations.

  Yet once if you can configure a second VPN L2L at some point then again would you use a different sequence number for this connection
