506th PIX and VPN client - multiple connections connections

• VPN client - multiple connection possibilities?

  Hi people,

  My basic question is, Cisco VPN Client allows two simultaneous VPN connections at the same time?

  I would like to implement the following:

  Customer user (remote access VPN via Internet)--> Head Office c/o ASA 5520 pair--> (VPN remote access via Internet)--> pair of Branch Office ASA 5510 S + a/s

  For example, to access the Branch Office system, the user must:

  1. connect to the peer of Head Office ASA via Cisco VPN Client (the user/password authentication)

  Head Office ASA peer gives an 172.16.1.x private IP address and is configured to route all requests for public office ASA IP through its own public IP address.

  2. once Head Office VPN is established, the user establishes a SECOND VPN tunnel of the Cisco VPN client (user/password and focused on the cert auth)

  I.e. branch sees the VPN connection try from the public IP address of Headquarters and therefore allows the VPN through the ACL traffic and allows the continuation of the VPN negotiations as usual.  Customer is given another IP address private, 192.168.10.x.

  Basically, I need to limit the remote access VPN branch to make it only accessible from Headquarters public IP address, no public IP address of the user (and therefore the entire internet).

  
  

  I know this is an unusual configuration, and some will say on the sensitivity of security to allow two simultaneous VPN connections.  These are the two networks of trust, strict ACL would be at stake and there is a long history behind this requirement...

  Thanks in advance!

  Alistair,

  You can limit the access of VPN connections to branch by blocking connections on UDP ports 500, 4500 UDP and ESP and allowing him only from your home office. In this way, only the explicitly authorized public IP address of your home office would be able to connect to your remote sites by using an IPSec tunnel.

  Now, on the second tunnel I don't think it's possible. As far I am aware you cannot have two connections to VPN at the same time of the same customer. The VPN will not let you do, it's mainly because when you have a VPN Client the VPN map session comes up and you can only one card virtual VPN.

  Because I don't think it is possible I would advice to try something like this:

  http://www.Cisco.com/en/us/products/HW/vpndevc/ps2030/products_configuration_example09186a008046f307.shtml

  Could provide you the connectivity that you are looking for without needing a second tunnel VPN from the client side.

  I hope this helps.

• Router vpn site to site PIX and vpn client

  I have two on one interface on the pix vpn connections that terminate VPN. client vpn and VPN site-to-site have passed phase one and two and decrypt and encrypt the packets. However as in another post I can not ping through the l2l vpn. I checked this isn't a nat problem a nd two NAT 0 on the pix and the NAT on the router access lists work correctly.

  I looked on the internet and that it points to a routing error when packets are being encrypted and decrypted, but you can't do a ping on the binding. However when I test the connection I did not enter any of the static routes that networks are connected directly on each side of the pix and the router. any help would be a preciated as I think there's maybe something is blocking the ping to reach the internal network at the end of pix with a configured access list.

  is ping failure of the only thing between the site to site VPN? and assuming that all other traffic works fine since it decrypts and encrypts the packets.

  If it's just ping, then activate pls what follows on the PIX:

  If it is version 6.3 and below: fixup protocol icmp

  If it is version 7.0 and higher: select "inspect icmp" under your political map of the world.

  Config complete hand and on the other could help determine if it's a configuration problem or another problem.

• PIX: Cisco VPN Client connects but no routing

  Hello

  We have a Cisco PIX 515 with software 7.1 (2). He accepts Cisco VPN Client connections with no problems, but no routing does to internal networks directly connected to the PIX. For example, my PC is affected by the IP 172.16.2.57 and then ping does not respond to internal Windows server 172.16.0.12 or trying to RDP. The most irritating thing is that these attempts are recorded in the system log, but always ended with "SYN timeout", as follows:

  We tried to activate and deactivate "nat-control", "permit same-security-traffic inter-interface" and "permit same-security-traffic intra-interface", but the results are the same: the VPN connection is successfully established, but remote clients cannot reach the internal servers.

  I join all the details of the cryptographic algorithms because the VPN is successfully completed, as I said at the beginning. In addition, routing tables are irrelevant in my opinion, because the inaccessible hosts are directly connected to the internal LAN of the PIX 515.

• VPN client, lost connection

  Hello

  I pix506e here... and vpn clients connected.

  But suddenly lost connection vpn client 40 minutes and then try to reconnect again but fail. If the vpn client restarts their pc/notebook...yes it can connected to vpn again... but the interruption of the connection again... then restart... and so on... What is the cause of this problem?

  Thanks for the help

  Tonny

  All remote VPN clients are having the same problem or is it limited to just a few. If the problem is seen with only a few, it is quiet possible that the problem is not with the PIX of the customer. In addition, the DPO is enabled or not. DPD will cause tips to know an IPSec connection over, where the SAs flusing, allowing new being negotiate quickly.

• VPN Client TCP connection to router IOS

  Hello

  I try to get a VPN client to connect via TCP to a router. I currently have the router put in place (and work) in using a VPN - UDP. Unfortunately one of the sites I visit will not allow VPN traffic outside of their firewall. I have searched all over the site of Cisco and can't find any information on the IOS configuration to accept TCP - VPN connections. I would like to change the TCP port 80, so my VPN traffic looks like just standard internet browsing my client firewall. Any links/pointer would be greatly appreciated.

  Thanks in advance!

• Cisco vpn client to connect but can not access to the internal network

  Hi all

  I have a VPN configured on cisco 5540. My vpn was working fine, but suddenly there is a question that the cisco vpn client to connect but can not access to the internal network

  Any help would be much appreciated.

  Hi Samir,

  I suggest that you go to the ASA and check the configuration to make sure that it complies with the requirements according to the reference below link:

  http://www.Cisco.com/en/us/products/ps6120/products_configuration_example09186a00805734ae.shtml

  (The link above includes split tunneling, but this is just an option.

  Please paste the output of "sh cry ipsec his" here so that we can check if phase 2 is properly trained. I would say as you go to IPSEC vpn client on your PC and check increment in packets sent and received in the window 'status '.

  Let me know if this can help,

  See you soon,.

• Binds two ISP ASA to remote VPN Client to connect to instead of creating two profiles on the remote client

  Hello

  just a quick,

  TOPOLOGY

  ASA isps1 - 197.1.1.1 - outside

  ASA ISP2 - 196.1.1.1 - backup

  LAN IP - 192.168.202.100 - inside

  I have configured Tunnel on the interfaces (external and backup), but is to link both legs public to serve a thare as redundancy for vpn users and users of the vpn tunnel leave pointing inside IP whenever they want to establish vpn sssion, we want it to be one, so if an interface fails vpn users will not know , but he will try the second for the connection. instead of creating the profile for the two outside of the leg on the vpn client.

  is this possible?

  Hi Rammany.

  In your case, you have only an ASA that connects with 2 ISP in another segment IP... 196.x.x.x (Link1) & 197.x.x.x (Link2). What your condition is you want to have the VPN client who must be consulted with backup. If 196.x.x.x link fails, it should automatically take 197.x.x.x link. That too we should not have the config set in the VPN client backup server. You don have the possibility of having standby active also in asa single.

  I think n so it will work with your current design.

  This option is if your VPN client supports host name resolution (DNS). You can have the VPN created for both the public IP address share the same host name keeping the bond as the primary address 1 and 2 a secondary address. It will work alone.

  Hope someother experts in our forum can help you with that.

• WAG-120N and static ip - wireless and wired clients cannot connect to the internet

  Greetings,

  I use the N WAG-120 AP and switch for 3 computers laptops and 2 Office. Our Department is assigned only a what IP static of our server, as well as a pc can connect to the server and the internet. I use the first lan port of the 120N Wag as a WAN port and I attribute the static IP address, and the subnet, default gateway, and DNS addresses. Connected clients receive an ip address from the DHCP (192.168.1.10x) router, but cannot connect to the internet. How can I configure my router to allow clients to connect?

  Thank you in advance!

  The default LAN IP of the WAG subnet is 192.168.1.0/255.255.255.0 belongs to 192.168.0.0/255.255.0.0. This means that 192.168.1.0 IP addresses exist side WAN and LAN of the WAG. What makes this configuration completely cannot be routed.

  Change the address LAN IP of the WAG to an IP outside the corporate network, for example using IP addresses private 172.16/12, for example to set the address LAN IP 172.16.1.1 with 255.255.255.0 subnet mask.

  The alternative would be to use the WAG as a point of easy access only, and not as a router. However, due to the 255.255.0.0 subnet in your network company you will not be able to access the web interface except from an IP address corresponding to the LAN IP address subnet of the WAG. Of course, this does not affect the wireless or wireline customers connected to the WAG...

  You must make sure that your internal traffic goes to the VPN client is NOT be NATT would be.

  You need to re - write acl 102 to something like: -.

  access-list 102 deny ip 192.168.4.0 0.0.0.255 192.168.4.0 0.0.0.255

• Firewall and VPN client

  What is the problem with the built-in firewall in which accompanies the VPN client? Is it good enuff to use with split tunneling, and it is always the same if the tunnel is not mounted?

  Nick

  The built-in firewall is a basic zone alarm firewall. No options to set it up, there you turn on or off. Default rule is rejecting all incoming traffic, it does not all outbound traffic. It is on the tunnel is up or not until you have it turned off. If you connect to a hub, you can configure the hub to push down her rules and require that its to connect. Yes its pretty good to use with the split in my opinion, tunneling but depend on your security policies.

• 1710 VPN and VPN Client - routing problem '' maybe. ''

  Hello

  I was able to get with 3DES and CISCO VPN Client 3.6.1 1710. with permission of local aaa.

  When I am connected to the VPN I can ping to the IP address of the VPN router

  (24.x.x.x.) and I can ping to the router's internal interface (192.168.x.x).

  The problem is that I can't ping anything else - for example: hosts in the enterprise network (192.168.x.x).

  Configuration:

  The router's internal IP address: 192.168.x.x

  The router's external IP address: 24.x.x.x

  ippool for customers: 10.10.10.x

  The IP address of the Client after the connection is correct: 10.0.0.x (from pool)

  Maybe I'm missing something in 1710 confg? I have NAT interface internal? The default gateway of the net is FreeBSD, not the router of 1710 system.

  All ideas are welcome.

  Miro Pendev

  Quite often, you will lose the first ping because an ARP must be sent and responded to, but if you get the subsequent pings, then it's OK.

  For what is able to browse the Internet while the tunnel is up, you must enable split tunneling. Add the following:

  > access-list 110 permit ip 192.168.1.0 0.0.0.255 192.168.1.0 0.0.0.255

  > isakmp crypto client configuration group my_usergroup

  > acl 110

  This means that the client will only encrypt the traffic to the 192.168.1.0 network, all other traffic shuts down in the clear on the Internet.
