• Wireless and VPN RV042 router WRT54G

  Respected member, please help if you can! I have an ADSL with dynamic connected with the wrt54g router, I recently bought RV042 and want to connect the wire coming from wireless with ports. so, basically, I want to use RV042VPN for help after the router, is there a way I can use vpn behind with port using RV042 router wireless

  I can't be able to connect to the vpn as he seeks is not an ip or WAN/LAN.

  It may be possible if you're lucky. But I highly recommend not to connect the RV042 after the WRT. A VPN server must always have a public IP address. Running a VPN server behind a router NAT (such as WRT) makes it extremely difficult and often it won't work at all. Connect the RV042 directly to your modem, configure it to your internet connection. In this way the RV042 has the public IP and VPN should become much easier. Then implement the WRT as simple access point in your network by changing the address LAN IP of 192.168.1.1 to 192.168.1.2, disable the DHCP server, and connect a LAN port of the WRT on a LAN on the RV042 port.

• Any java API to delete profile wifi and vpn

  Hi, I am trying to API seeks to delete the wifi and vpn profile after searching autour and read the documentation of the API, I found nothing. I think that there is no such API. Could someone give a confirmation on that? Thank you very much.

  never heard of an API for that

• WRVS4400N with AG300 and VPN connections

  I bought a WRVS4400N router hoping to add wireless and VPN capability at a remote office LAN. I want to be able to establish a VPN connection from my PC to the central office to the WRVS4400N to remote desktop, access and administer systems at the remote office. Remote desktop systems is unnecessary access to systems to the central office.

  Before you deploy the WRVS4400N to remote desktop, I'm stable and by configuring it to our central office.

  Our central office is a router Linksys AG300 and ADSL service for Internet connection. It works well and I don't want to change it.

  I have connected the WRVS4400N to our central office LAN and it has an IP address on its WAN port assigned by the DHCP server on the AG300.

  What I do not understand how to establish a VPN connection to a system on the Internet at the WRVS4400N on the local network. I have a laptop with the QuickVPN software installed. If I connect my laptop to the AG300 (i.e. the same switch as the WAN port on the WRVS4400N) I can establish a VPN connection to the WRVS4400N but if I connect to my laptop to the Internet (via my ADSL service at home), I am unable to set up the VPN. I don't know how to configure the AG300 so that the VPN from my laptop reaches the WRVS4400N.

  I transfer ipsec enabled on the AG300, but this does not seem to run the VPN with the WRVS4400N.

  Can someone tell me what I need to do?

  Is there some other DSL modem I could use that facilitates the connection? There is another DSL modem (I don't know make/model until I visit the site) used in remote desktop, but I could replace it if I knew that the replacement work.

  Update: I got it to work. See https://supportforums.cisco.com/thread/2108785 for the advice that has been most useful.

  The essential steps have been before the ports indicated in this article (and UDP 500) to the WRVS4400N and I dropped a bit of the MTU (do not know if this was really necessary). Now I can establish connection QuickVPN, except when the Windows Firewall interferes.

  Hello

  Thank you for posting. In the AG300, transmit the following ports to the IP address of the WAN WRVS4400N port: 443, 500, 4500, 60443. This allows you to establish a QuickVPN for the WRVS4400N using the WAN IP of the AG300.

• Can fast VPN and VPN Cisco coexist (WRVS4400N)

  I am looking to buy a WRVS4400N to take care of my home network.  While I get out on the road I want to VPN in my home network to my laptop (on which I installed Cisco VPN for the company's mobile access to my corporate network).  In this spirit, I have three questions:

  1. is the Cisco VPN client on my laptop be able to establish a VPN connection to unity WRVS4400N?  I suspect not, and instead, I have to use fast VPN.

  2. I understand there are problems in co existence with different suppliers, VPN clients (when I tried before with a Netgear router, the VPN Netgear client broke the Cisco VPN client).  Quick VPN client Linksys can coexist with the Cisco VPN client without any problems?

  3. a last resort, if Cisco and Linksys VPN can coexist, install the client quick VPN Linksys inside a VM Ware image would work (while the Cisco VPN client is still installed in the host operating system).

  Thanks much for any help.

  (1) correct.  For WRVS4400N QVPN

  (2) I run the Cisco VPN CLient and VPN fast on my laptop and seems fine

• GANYMEDE + for the unified management of ASA and VPN auth

  Hello, I have ASA 5540 and 4.2 ACS (AD backend), I want authentic unified management and vpn access.

  For example, I have two groups in ACS (mapping AD): Admins, VPN access.

  I wish that Admins have full access (shell, VPN) and "Access VPN" only vpn, without shell of any kind.

  I understand how to do with RADIUS - use 'Service-type' and network access profile, but how to do it with GANYMEDE +?

  There is something

  I explained to him almost the same scenario in the post of 2008

  https://Cisco-support.hosted.Jivesoftware.com/message/853751#853751

  To achieve this, you should have even ASA added to GANYMEDE and RADIUS AAA cleint.

  

  Since you want to group admin must have FULL access so don't change anything on this group.

  Now vpnaccess Group on ACS must have only access to the VPN, then here you need to implement IP-based NAR

  Go into the setup of the Group > ip based NAR

  

  I hope this helps.

  The sequence number of card crypto for the static mapping crypto (site to site vpn) should be higher (ie: sequence number must be lower) than the ezvpn (map dynamic crypto).

  In your case, you must configure as follows:

  map easyvpn 10 ipsec-isakmp crypto
  defined by the peers (deleted)
  Set transform-set vpn
  game site address

  map easyvpn 150 - ipsec-isakmp crypto dynamic easyvpn

  Hope that solves this problem.

  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.

• How to configure NAT for Hyper-V on laptop with wifi, wired and vpn connectivity

  Me, as I suspect a lot of people, I have a laptop with WiFi connection, cable connection and VPN connection (Cisco AnyConnect), which

  also uses a virtual adapter (activated when active). I searched for some time a way to be able to move to

  Hyper-V in VirtualBox. Blocker full for me is the need for a lot of my virtual machines to be able to connect to the

  Internet through 'the connection active' in the way that VirtualBox and VMWare Workstation/Player through their NAT feature.

  I'm not a networking wait, but after looking around, can't seem to find something that is simple enough for me to configure,

  with a minimum of resources, which allows me to connect a Hyper-V virtual network via a simple NAT device adapter

  all three potential network connections - most seem to not assume that one connection out of the machine, which of course does not

  me what I want.

  Three questions:

  1. is there a Windows application available that an adapter (like loopback) internal which acts as a real NAT device to one of the surfaces

  external access via the active network connections and through the Windows Firewall and any other antivirus, components etc. for

  the road to (i.e. behaves like a "normal app" inside Windows for internet access)? It would be the best option, because it would be

  "always there" when I run virtual machines

  2. display of my lack of knowledge around this feature, don't RRAS (and I know that this is not an option "minimum contact") allow you to

  Connect an internal network adapter to several external network adapters?

  3. on the Linux/OpenBSD various base/NAT routers, are everything that allow several external adapters and who are

  relatively easy to set up (by an independent expert of the network)?

  Really, we could do with this feature for Hyper-V on the desktop, but willing to work around him, if there is a way to at least the

  use virtual machines, once it is easy to install.

  Hello

  The question is more suited in the TechNet forums. So I would say you mention the link and send the request in this forum for better support.

• VMware Fusion 5 with Windows 8 and VPN

  Hi, I'm new to VMware. I am connected to my company via wifi VPN. I configured the VMware to connect through NAT. VPN seems to work fine on OSX, but in windows (VM) it says "no internet access. Internet works fine when I'm not on the VPN, but as soon as I connect to the VPN connection is lost. I tried to reload the OSX and Windows number of times. I tried ipconfig/release, ipconfig / renew on windows as suggested by other posts.

  Please let me know if you have any ideas to get this to work.

  In addition, the VPN was working fine until recently on another Terminal Wifi. I'm traveling now and I am facing this problem with wifi again. Not sure if there is wifi problem. Although I doubt that because the internet seems to work fine without a VPN and VPN seems to work fine under OSX. It's just VPN on VM that has a problem.

  I agree to what Akotsur said. Probably, you might consider configuring VPN Windows separately keeping in bridged mode.

• By PAT and NAT VPN

  We have a place where you want to set up a tunnel VPN to our headquarters.

  In this place, there is a router that PAT (NAT overloading), and then a few jumps more, there is a firewall that makes the NAT.

  Is this could pose a problem for the VPN tunnel?

  Here's a "pattern" of what looks like the connection.

  Customer--> PAT - router-->--> Internet--> CVPN3005 NAT firewall

  I hope you can provide me with an answer.

  VPN tunnel will not work in your scenario. NAT second change address and the ports you want to use for the vpn tunnel. So the port 500 wil be translated to top port and will be rejected at HQ.

• PIX, VPN, PAT and static

  I want to activate an incoming and outgoing VPN on a PIX configured with PAT. I enabled ESP and UDP/500 on the appropriate access to the lists, but must provide a static for inbound traffic. I already use a static for incoming SMTP traffic, and I don't see how to do the same thing for udp/500, but how do I ESP traffic?

  Any suggestions gratefully received.

  If you are referring to a static port, you can create one for ESP since static port can only be created for TCP/UDP and ESP is located just above the intellectual property, it is NOT a TCP/UDP protocol. You will need to create a one-to-one static for this internal VPN server and have your clients to connect to this address. This will chew global IP address to another one, sorry.

• PAT/NAT and VPN through a PIX

  "PPTP through the PIX with Port address translation (PAT) does not work because there is no concept of ports in GRE"-this is an excerpt from a config PIX version 6.2 and below.

  1. how this problem has been fixed in 6.3? GRE is encapsulated in udp or tcp to use ports to follow the connection?

  2. is it "fixup protocol esp-ike" use the same technology - the source port created by the IKE protocol? -ISAKMP cannot be enabled when you use this command

  3. What is "isakmp nat-traversal? How is this different from fixup protocol esp-ike"

  Thank you

  RJ

  1. when the PIX sees outgoing PPTP (TCP 1723 port) packets it now opens holes for them to return, as well as opening a hole for the GRE packets, it has never done this before. The PPTP TCP packets can be PAT would be fine because they are TCP packets. GRE packets, I believe, are followed by the id field only tunnel in the package.

  2. we use the source port of the ISAKMP packet for ESP packets as well. The current limitation is that if you have this option, you cannot use the PIX to close the IPSec sessions, so you can not turn on ISAKMP any interface. You can also have only a single IPSec client internal to use this feature.

  3 NAT - T is a new standard for IPSec to work through a NAT device peers, because they detect changes of address during the negotiation of tunnel and automatically encapsulate packets in UDP 4500. This market allows the PIX and the other device (if it supports it) to automatically detect a NAT/PAT device between them. This differs from the "esp - ike correction '' that the PIX ends not in fact the IPSec tunnel with esp - ike, but it is the endpoint in nat - t.

• 506th PIX and VPN client - multiple connections connections

When the second user connects, the first is finished and the second works very well. The product turned on States I should be able to have 25 simultaneous connections or site to site or customer.

  Any help will be greatly appreciated, Kyle

  Are these two users on the same site, behind a device that makes PAT? If so, then this device is causing the problem, not the PIX. The device is unable to correctly translate the IPsec packets. Unfortunately nothing you can do about it on the PIX, although the next version of the software (6.3 to your calendar of March) will have NAT - T support (which the client currently supports). Once that support NAT - T both ends, they'll be able to say that there's a PAT instrument between the two and they will automatically encapsulate everything in the UDP packets, which your PAT instrument will be able to translate correctly.
