Configure the firewall to allow VPN connections to a remote site

Hi all

I do a lot of how to configure VPN servers, so please bear with me if I explain a bit wrong!

If all goes well a quick question, I am trying to connect a VPN client that is located behind a firewall at a remote PIX server using RADIUS authentication. I am able to ping remote IP of VPN server, but cannot connect - errors are "peer remote unresponsive" for UDP and "has not established TCP connection" for TCP.

Topology of the short...

Local PC, fixed IP 192.x.x.1, using VPN Client 4.0.3

Connect through firewall type unknown to the Internet

This firewall has outgoing ping enabled, and temporarily all UDP and TCP ports open for pc local ip above fixed.

VPN client configured with access to the group, and I tried to use UDP and TCP, with and without transparent tunnel.

Does anyone have any suggestions as to why the connection cannot be made even if the IP of the target can be crazy?

Thanks in advance,

Dave.

  • 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?

  • Cannot configure the firewall using vSphere client (access to ESX 4i)

    I can't acess the firewall by using the client vSphere connection to a host of 4i ESX.  I select the host & gt; configuration & gt; Safety profile & gt; and it flashes firewall briefly, but then watch as services (two) (VMware vCenter Agent (arrested) and NTP daemon (started).

    Clues?  I restarted services (and the host itself).

    ESXi should be behind a firewall because there is no firewall integrated its own.

  • Is there a way we can configure the oracle database to accept connections from particular type. For example, we may limit Server Oracle don't not to accept applications for connection to the JDBC thin driver?

    Very similar to the question of the configuration of the switch. You should check if there is no specific roads on the switch outside the default gateway. The switch should route the subnet pool ip to the firewall (10.0.2.254).

  • VPN clients cannot access remote sites - PIX, routing problem?

    I have a problem with routing to remote from our company websites when users connect via their VPN client remotely (i.e. for home workers)

    Our headquarters contains a PIX 515E firewall. A number of remote sites to connect (via ADSL) to head office using IPSEC tunnels, ending the PIX.

    Behind the PIX is a router 7206 with connections to the seat of LANs and connections to a number of ISDN connected remote sites. The default route on 7206 points to the PIX from traffic firewall which sits to ADSL connected remote sites through the PIX. Internal traffic for LAN and ISDN connected sites is done via the 7206.

    Very good and works very well.

    When a user connects remotely using their VPN client (connection is interrupted on the PIX) so that they get an IP address from the pool configured on the PIX and they can access resources located on local networks to the office with no problems.

    However, the problem arises when a remote user wants access to a server located in one of the remote sites ADSL connected - it is impossible to access all these sites.

    On the remote site routers, I configured the access lists to allow access from the pool of IP addresses used by the PIX. But it made no difference. I think that the problem may be the routes configured on the PIX itself, but I don't know what is necessary to solve this problem.

    Does anyone have suggestions on what needs to be done to allow access to remote sites for users connected remotely via VPN?

    (Note: I suggested a workaround, users can use a server on LAN headquarters as a "jump point" to connect to remote servers from there)

    with pix v6, no traffic is allowed to redirect to the same interface.

    for example, a remote user initiates an rdp session for one of the barns adsl. PIX decrypts the packet coming from the external interface and looks at the destination. because the destination is one of adsl sites, pix will have to return traffic to the external interface. Unfortunately, pix v6.x has a limitation that would force the pix to drop the packet.

    with the v7, this restriction has been removed with the "same-security-traffic control intra-interface permits".

    is there any software to install so I can get this laptop on the network?

    The software is available, but you need... or power borrow for 10-15 minutes... a former Mac running Leopard (10.5.x), Snow Leopard (10.6.x) or a PC with the utility AirPort 5.6.1 for Windows installed on the device.

    Sometimes users ask to see if the software is available from another source. Software not allowed is available on the Internet, but it is written by an 'unknown' author to Apple, which will provide no. help or support if you have problems with your Mac. In addition, the installation of the software without permission will require that you change (lower) some of the security settings by default on your Mac.

    Apple will not post the link to the software on this forum, even if you are willing to assume the risks of trying to use it.

  • Configure the firewall on the esxi host 4

    Team Kia Ora

    I built an esxi host 4 on a piece of the material I had to hang around, as you do!

    I'm eager to open ports in firewall on the host.  I can't tick all the ports incoming and outgoing, I need tab of safety profile VC client (configuration of the host), and then select Properties.  Also the esxcfg-firewall command is missing, even when I use a UMA VMware to place orders RCI to the host, there doesn't seem to be available.   ?:|

    See attachment "... - nzwlg - stack - 1.png".

    On esx 3.5 or esx 4, I use the host configuration SecurityProfile tab, select Properties, click on the appropriate ports and in and facts. This feature seems to have moved/missing?

    Also, strangeness, is that I have another esxi installation 4 which has the parameters display correctly under the Securityh profile | Properties tab. ?  (attachment "... - nzwlg - pile2.png")

    Any help greatly appreciated and have a great week! =)
