• 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-

  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

• Cisco ASA - l2l IPSEC tunnel two dynamic hosts

  Hello

  I have two firewall Cisco ASA an i want to made a l2l between two ipsec tunnel, the problem is that both parties have a dynamic IP, on both sides I have configured dyndns, can I did an ipsec tunnel using dyndns name such as address peer?

  Hello

  ASA supports only the RFC compliant method for updates used with dynamic DNS, not updates HTTP, such as dyndns.org and others use.
  i.e. https://tools.cisco.com/bugsearch/bug/CSCsk25102/?reffering_site=dumpcr

  On ASA, it is not possible to configure the tunnel between two dynamic peers.
  You will need to have a static end to configure static to dynamic IP.

  For routers, you can follow this link.
  I hope this helps.

  Kind regards

• ASA VPN IPSec: MTU or CFG error Question?

  Hello

  I have a strange problem... If I created a tunnel IPSec the ASA vs, it goes up but doesn't work if the package + / less 150 bytes... case of exceeded the size of the packets, the ASA didn't send to client IPSec; The size is related to the type of configured tunnels:

  Thank you

  Arturo.

  This is much like the following bug:

  CSCsu26649    Big packages removed with enable configured ip-comp

  Can you confirm that you have 'enable ip-comp' in your config vpn file? If so, that que desactiver turn off and you should be ok.

  Better yet, go to 8.0 (5).

• No Internet VPN IPsec Tunnel access

  I use the Netgear VPN - Pro 5.51.001 client to configure and run a VPN Tunnel to a UTM10 (3.5.2 - 14). It works very well so far and my private network resources could be achieved.

  When the tunnel is established, the client (W7 x 64) loses connectivity to the Internet on LAN or WLAN port desired and expected.
  Now, the Internet connection must be provided inside my private behind the UTM network.
  Due to a DNS SERVER running on my private network addresses (even on the internet) are correctly resolved (use NSLOOKUP to check), but cannot be routed to my VPN client.
  I found, that the map virtual Green-bow had no entry for the gateway, but the entry door (my UTM10) could be ping from the VPN client.
  After you enter the internal IP address of the UTM in the field of "Redundant GW" of the client software and restart and reconnect to the customer,
  the entry door is now displayed in the properties of Green-bow (ipconfig on CMD-screen), but still no internet site can be reached.

  To test, I have disabled the firewall on my client PC.
  The tunnel use mode-config and receives the entries in DNS and WINS server according to the config folder. The client is configured to force the NAT-traversal.

  Customers should be able to connect from the offices at home (or mobile) to the network/domain of society and use internet as if they were connected locally.
  SSL - VPN is not an option.

  No, it doesn't work like that. If you want to "full-tunnel" support you need to stick with SSL VPN and select this option in the settings.

• Type of certificate for ASA VPN IPSEC

  Hi all

  I'm looking to set up an IPSec VPN connection that will authenticate users by certificate only. I configured everything successfully with the local AAA login, but seeks to convert a signed certificate and generate certificates user for users that are not part of a company or Active Directory.

  So here's my question. What kind of certificate I buy (lets say VeriSign aka Symantec)? And if I want to only use this certificate for my VPN and its customers, can I install it on the Cisco ASA and generate user certificates, or should I set up a Windows Server with CA and create all the certificates on this machine?

  My goal is to install the agent AnyConnect 3.1.x on laptop computer of the user, install the certificate user myself. No webVPN or on behalf of the user. I tried the local certification authority in the ASA in a dev environment, but have had no luck so I thought I'd just signed good immediately.

  Thanks in advance,

  BROKEN

  > Do you think I should have a 3rd party signed certificate

  If the VPN is not only used for internal staff, and then always opt for a public certificate. If you ask other users to install your root certificate, you ask them to allow you to be a man in the Middle for all their traffic. It's nothing that needs to be done.

  Registration is generally just to configure the trustpoint and install the certificate. It is very likely that the certification authority uses an intermediate certification authority, so you should install that also. (even keep the AC have howtos on various platforms).

  > I'm still learning here so I apologize if my questions seem to be amateur.

  And be assured, learning never stop... :-)

• IPSec Tunnel site to Site between ASA (static IP) to the firewall Microtick (dynamic IP) cannot telnet routeros and open https

  I purchased Mikrotik hardware devices and want to use routeros seat firewall cisco asa establish VPN. Aims to establish that a branch may be two IPSEC VPN access devices at the headquarters of the server via the public network.

  But now, I'm having some trouble, so I have cisco asa branches and headquarters to establish successful ipsec vpn.
  (1) branch routeros WAN port using a private IP address and is a member of the asa above outdoor sound created vpn ipsec, vpn successfully established internal servers and I ping the switch at the headquarters of the branch. However, there is a problem, I go through routeros visit that the headquarters of the https server pages can not be opened, telnet internal switches can telnet to the top, but were unable to penetrate into the character.
  (2) in addition, I left the branch routeros on a public IP address WAN port and asa VPN IPSEC created seat, said problems above are not, the server can also be accessed, telnet switch can also enter text and control.
  At the present time, I have encountered this problem of interface not CAN not because I need to create of very, very many industries and the need to establish headquarters communications branch offices so I have to use private IP addresses to access the Wan, unable to do wan are public IP address and headquarters to establish IPSEC VPN.

• 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.

  Steve

  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.

  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."

  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.

What did I DO WRONG (also, I don't have access to the Checkpoint Firewall (PE)) how their installation would be or how it should be to allow bidirectional routing?

  No, u certainly shouldn't allow 0.0.0.0 for proxy ACL. Again, your config is very good. In addition, package account, this show that traffic is going throug the tunnel in two ways:

  #pkts program: 3207

  #pkts decaps: 3417

  Also, looking at the meter, I can guess that some of the traffic comes from the other site, but does not return back (maybe that's where you can not connect from behing Checkpoint). If you say that 0.0.0.0 solved the problem, are there no other NAT rules for subnet behind ASA, so the server IP, for which you are trying to connect behind the checkpoint, translates into something else (not the beach, included in proxy ACL), when to come back?
