Specific customer VPN - how to restrict to host/port?

Hello

I have a PIX-515 performer 6.3.5 code using Firewall/VPN device. I have a lot from site to site and VPN client works well. However, I'm looking for a way to split tunnel to the port grannularity level.

for example, vpn profile Fabricant2, limit access to the 192.168.100.210 on port 80 and 81 only. Here is my config.

object-group service tcp tcp-80-81

Beach of port-object www 81

object-group network consultant-vpn2-dst

host of the object-Network 192.168.100.210

object-group network vpn-clientpool-2

network-object 192.168.101.64 255.255.255.224

!

access-list consultant-vpn2 permitted tcp object-group consultant-vpn2-dst object-group tcp-80-81 object-group vpn-clientpool-2

access-list no. - nat permitted tcp object-group consultant-vpn2-dst object-group tcp-80-81 object-group vpn-clientpool-2

!

192.168.101.64 - 192.168.101.95 pool2-vpn IP local pool

!

NAT (inside) - access list 0 no - nat

!

vpngroup address vpn-pool2 pool Fabricant2

vpngroup Fabricant2 by default-domain mydomain.com

vpngroup split Fabricant2 consultant-vpn2 tunnel

vpngroup idle time 1800 Fabricant2

Fabricant2 vpngroup password *.

This config works fine but when connecting, I see the split tunnel which passes on the IP level. I am able to ping or pass another type of traffic to the host, even if the ACL is extended and only port 80/81.

Is there a way to limit the VPN client to a specific port only?

One solution would be to...

1. remove the allowed sysopt connection ipsec

2. write access you want in your list of outside access.

No ipsec sysopt connection permit

outside_access_in tcp object-group allowed access list vpn-clientpool-2-object-group consultant-vpn2-dst eq 80

outside_access_in tcp object-group allowed access list vpn-clientpool-2-object-group consultant-vpn2-dst eq 81

Access-group outside_access_in in interface outside

Note: the actual acl may vary depending on what you already have. Also if you have other virtual private networks, these subnets access should be allowed since the removal of the sysopt command block access.

  • Routing quirks SSL customer VPN - more

    I studied SSL VPN-Plus feature on NSX Edge Gateway and I noticed something really weird just how customer VPN traffic is routed. All client TCP connections are NAT'd to closest edge interface address, any other protocol is routed by using the IP address of the affected client Pool of IP.

    Example of

    Bridge Board with two interfaces

    -outdoor = x.x.x.x

    inside-a = y.y.y.y

    VPN client

    -IP address = z.z.z.z


    Ping ICMP customer VNP with IP address z.z.z.z arrives at its destination with IP address z.z.z.z

    UDP DNS queries to customer VNP with IP address z.z.z.z arrives at its destination with IP address z.z.z.z

    Application of TCP HTTPS client VPN with IP address z.z.z.z arrives at its destination with the IP edge gateway interface address y.y.y.y

    I have no NAT configuration defined by the user in place, only NAT rule is rule DNAT system default for the external interface (uplink).

    That's serious problem with SSL VPN-Plus, I filed a request for support if could, but since I am a student help on licenses NFR partner without support I can't.

    Ed. also tested the UDP

    There is a flag in configuration edge-> sslvpn-> private networks-> specific entry-> 'enable TCP optimization '.

    Disable that and you will see even the client ip TCP connections.

  • ASA 5505 like customer VPN simple AM _ACTIVE status

    Hi Experts,

    We have an ASA5505 which is configured to operate as a simple customer VPN. The output of isakmp #show his indicates the State of the tunnels as AM_ACTIVE.

    But we are not able to establish connectivity to one of the Interior knots.

    What does AM_ACTIVE mean? My understanding of all the Clients VPN easy hardware or software, use aggressive Mode and the tunnel is set up and works. Easy VPN server configurations is not under our management, which is most likely a router, and we believe that it is the problem of configuration at the server end.

    In addition, there is virtually nothing to do on one customer another easy VPN that specify authentication and tunnel group information in the client, and it must be connected. All other configurations are pushed from the end of Easy VPN Server, right?

    The output of ipsec #show his , noted the following

    dynamic allocated peer ip: 0.0.0.0 ---> is this to say that this isn't my ASA5505 assigned any IP by the easy VPN server?

    #pkts program: 3, #pkts encrypt: 3, #pkts digest: 3

    #pkts decaps: 0, #pkts decrypt: 0, #pkts check: 0 ---> no decryption, which probably means that there is no response from the remote end, right?

    compressed #pkts: 0, unzipped #pkts: 0

    This may possibly be due to a bad end of server configuration and the cause of not being able to establish connectivity to the end server nodes?

    Help, please! Sorry for the mess, but we want to just make sure that it isn't something wrong with the configuration on our side!

    Kind regards

    ANUP sisi

    There are 2 phases of IPSec: IKE (Phase 1), status of the AM_Active Phase 1 means is running, and IPSec (Phase 2), and if you have both figure and decrypts increment which means the tunnel past the traffic.

    Based on the output, the VPN tunnel is up and sends traffic to the network/VPN server, however, there is no response in return.

    You should check the end of the VPN server to see if there is no configuration issues. Discover the NAT exemption and ensure that you have configured on the network head. How do you set as? PAT/Client mode or NEM?

  • How to get the host name of the physical computer inside a virtual machine until the user logs in Windows?

    I don't know if this is the right place to post this question, I develop software to support VMWare PCoIP and need to know how to get the host name of the physical machine (which manages the virtual machine and View Client) within a virtual machine before the user logs in Windows of the virtual machine.

    I understand there are two ways to read the host name, via the HKEY_CURRENT_USER\Volatile Environment registry and environment variables, but they are available once the user is connected. I need info before the user connects.

    Is there a VMware API that can be called or asked the host name?

    Thank you.

    Not on the broker, but there are the startup scripts to log on to the computer virtual itself: http://pubs.vmware.com/view-52/topic/com.vmware.view.integration.doc/view_integration_startsession_script.9.2.html

    Note that these executed when a virtual desktop computer allocated connection, not to the point that the client connects - it is possible for the customer to not complete the connection (crash, cancel, network failure) and so any what solution you design must handle this.

    Hello

    This is probably the result of malware then do a very thorough check and when the

    If you need search malware here's my recommendations - they will allow you to do a thorough check and removal without ending up with a load of spyware programs running resident who can cause as many questions as the malware and may be more difficult to detect the cause.

    No one program cannot be used to detect and remove any malware. Added that often easy to detect malicious software is often accompanied by a much harder to detect and remove the payload. So its best to be now too thorough than paying the high price later. Check with them to an extreme exaggeration, and then run the cleaning only when you are sure that the system is clean.

    is it possible to prevent iTunes to change my hard drive? I just got a new iPhone 5 as a gift, and when I tried to put my music on the phone, I had problems, which culminated with iTunes in deciding to delete my collection of mp3 from my computer. She also somehow FUBARed a DVD - RW I had saved my collection on when I made the mistake of trying to copy them to the phone from the backup DVD (must have burned a DVD-R).

    Is it possible to limit the access of iTune hard disk read-only until I learn how to prevent FUBARing my music collection? Really, I hate having to get out of my backups. I am seriously thinking the iPhone back and get something less restictive does insist on managing my music for some reason any.

    All programs will not automatically modify or access the files, unless the program is asked to go to the location, you may have set some options in the iTunes software. Given that the Apple support would be better suited to help you with this problem. Refer to this link and ask the question
