GET overhead VPN
Hi all
We are looking for overhead represented due to GET VPN. Is there a table of comparison or the value.
Thank you
Concerning
Anantha Subramanian Natarajan
Anantha,
As mentioned by Lloyd, GETVPN the new IP header is a copy of the original IP header. So, who's going to be 20 bytes (without options). Please keep in mind that the size of the package may vary depending on the options of encryption and authentication as AES, SHA, etc.. Basically, around 52 to 56 bytes. Thus, with the new IP header, looking at 72 to 76 bytes.
I will quote the ESP RFC 4303 for more details.
I have not seen a document of specific performance GET VPN on cisco.com. But, since the Original IP header is copied and placed in front of the ESP instead of a new IP as the traditional IPSEC header, I don't think he'll be a lot of difference in the performance of encryption between traditional and GET VPN.
I hope it helps.
Kind regards
Arul

What ports should I use to get the VPN RA worked?
Hello
I have a few tunnels l2l. I don't use "vpn sysopt connection permit" command. I prefer to activate the required ports for specific source IP. So they can establish the VPN tunnel with me.
Recently, I have configured remote access vpn. It is work very well... But only when I activate "vpn sysopt connection permit.
Question:
1. what ports need to be activated to get RA VPN work? (without vpn sysopt connection permit)
2. How can I restrict the access of remote when clients they connected to my private network?
Thank you
Leo
Hi Leo,
When you are not using 'connection sysopt... '. ", you must explicitly permit udp 500 and udp 4500, traffic esp on the outdoor access list.
Let's say that public intf outside ip address is x.x.x.x and pool customer, we use y.y.y.0 and you want to allow 'only' traffic for port 80 through the tunnel.
In the ACL on the outside, you need the following instructions:
access-list 101 permit udp any host x.x.x.x eq 500
access-list 101 permit udp any host x.x.x.x eq 4500
access-list 101 permit esp any host x.x.x.x
access-list 101 permit tcp y.y.y.0 255.255.255.0 eq 80
access-list 101 deny ip 255.255.255.0 y.y.y.0

Get the VPN without dedicated key server
Hi all
We plan to implement Get VPN in our collection company and place the pieces necessary to complete setting up VPN access. And I have a question about the present.
Do we really need a dedicated server key? I mean I know that the key server cannot be a member of the group, but here's my question. I have a router that is configured for some voice features. And I do not want to be a member of my VPN infrastructure get (but it will be on the network and available to offices and remote sites). If this router can be configured as a server key and still perform other services such as speech or other things? I really need to know if this can work.
I'd appreciate a quick and accurate answer that this forum is my last resort. Thanks in advance.
-Jay
Hi Jay
You must be a key server, as is the router that will push the political security to members of the group. But it cannot be part of IPSec connections that is, not a member of the group.
You can run other services and features on this router. But it should not affect the ISAKMP and GDOI traffic among the members of the group.

How can I get the Client VPN or NAT - ted connection
I installed a router on a customer site to replace a PC that made the NAT on a cable modem connection.
On the router THAT NAT is done to get all the s PC on the LAN to access the Internet.
But... one of the users use a VPN client to get to his office. With the PC, there is no problem, but given that the router is in place it can not connect.
Because I specialized on switched networks my knowledge; edge of NAT and VPN clients.
Is there anyone who knows how to get this VPN client-session user to be NAT - ted?
Kind regards
Martijn Koopsen
If you have some onfigured of overload, then you tap the traffic. In all cases, you should at least be able to establish a connection, as IPSec uses UDP 500 for the negotiation of the tunnel. If you are not able to pass all traffic, it is another question. Once the tunnel is established, the traffic can be encrypted using the Protocol ESP who cannot be tapped under normal circumstances. If this is a cisco IPsec client, then you must discover which is the feature of termination. If it's a hub 3K, you could activate IPSec over UDP to the problem of circumvention the ESP
Hope that helps

VPN connection: An unexpected error has occurred.
I am suddenly unable to get my built-in VPN connection works on my iMac with OS X 10.11.5. I get the VPN connection message: an unexpected error has occurred. I have been using this VPN configuration to connect to work for several months with success.
But last week (and I do not know if it had nothing to do with it), I went on vacation and used a free wi - fi setup of Tim Hortons. I had a LOT of trouble getting the next login page, and I checked all playing with different settings of network without success. When a change did not work, I put it to its original setting. Finally, I learned to use Safari to access the free WiFi connection page of Tim. Then once connected, everything was OK.
But when I returned a week later and if necessary, to start my VPN connection to access the work, it wouldn't start. I checked and recheck all my settings preferably of different network, but did not find those who were wrong. I even deleted and re-entered my VPN service definition without solving the problem.
Thinking that the problem could be the newly installed ISP of Bell equipment (we went from Rogers while I was away), I used my BlackBerry smartphone (issued by my employer) to create a wi - fi hotspot and accessed to the internet using this connection which completely ignored my home ISP equipment. But still, I was unable to establish a VPN connection.
I then tried my iPad VPN connection, and it worked! Then, I defined a VPN service on the iMac to my wife and the iMac to my daughter and was able to successfully establish a VPN connection to my work very well, using exactly the same VPN configuration. This led me to the conclusion, it was a problem on my iMac (and not with my new ISP or VPN system of my work that had none of the changes you made), but I still can't find what is "broken". I run Onyx for my iMac OS X 10.11.5 and repaired permissions and clean the cache and all the rest she is doing to "solve" problems. But the problem persisted.
Is there a preference file corrupted somewhere (scan option is no longer on the current version of the Onyx for a reason any)?
I still have a network setting wrong somewhere I need to go back to the system is correct value?
Here is the attempt to VPN from the file system.log (with some hidden values in the case where they display my work VPN access):

I finally found my VPN problem.
There is a 'racoon' file that is generated when I connect to the VPN to my work site.
I have created a modified version of this file so that my connection does not expire in 3600 seconds (changed in 24 hours).
Apparently, there are some slightly different settings (such as certain IP addresses other than VPN IP of my work) in this file under our new ISP Bell from the former FAI Rogers.
And if I connect to the WiFi Hotspot from my BlackBerry, it does not once again because these settings in the file are different again. I must return the file generated instead of my modified file.
Bad luck!

I want the password protect the VPN toggles
IM aiming to put a lock on the VPN code switches as a means of Internet security. So far, using a VPN internet filter was the best method of filtering * sites because the restriction in iOS setting is either
(1) too broad - the parameter filters too many sites that are not 'bad' according to my criteria and Internet which uses a hassle or
(2) not wide enough and inefficient - if I have to enter each unique web address, that I want to block by hand, I'll never be able to get all of them.
OpenDNS umbrella VPN is inexpensive ($20 years OLD!), relatively fast, be online most of the time and is effective. The only problem is, as many have said, Apple provides no way to get the VPN settings.
Jailbreaking would provide tweaks to do this, but I don't want to go this way (although I feel that apple encourages this line).
I looked in other methods, like the Ciscos Maraki new mobile device management. As a professional IT Tech. tool, maybe it's the best option, but it is not always easy for a novice to networking semi guy like me to understand.
Fundamentally, I believe that Apple needs to work on its policy of the device settings. They need develop a control system easy to use and easy to use. Families and small businesses are ever needing management tools complete device for all levels of mobile devices. access to the network, access app, followed by the app, ext.
I want to control and monitor the use of my family, it's so dangerous content out there and new ways to hide profane and damaging activities opens too quickly for an individual to find ways to control us needed tools to help us.

I can't get my VPN to work. It connects, but not change my IP address and allow me access to my network home.
Here is my configuration:
Comcast - router in Bridge mode
-Nighthawk R7500
-Macbook pro with tunnelblick (tried both viscosity)
I have a dynamic DNS, which has been well updated, I tried all the options VPN configurations (tcp, udp, auto, home network only, all the network domestic sites and internet, even made manual configurations in the vpn file to try to force something.)
The problem is; I can connect to the VPN server, but that's all. Nothing changes, I can't access my home network, my IP address does not change, I don't know what it is even made or connect to. I installed a dozen files configuration doing this, and one of the reasons why I bought this router was due to the VPN. Any help would be greatly appreciated, I really want this VPN to work.
OK I thought about it. I went the subnet of my
Network servant 172.16.x.x and it works fine now. -
Cisco VPN problem with security update KB3057839 for Vista
Someone had problems with any connection Cisco VPN works after the installation of update of security KB3057839 for Vista? When this update is installed, the pop-up to enter the password and user id not come, need to use the Task Manager to close the program. The first time I went back to the restore point to get my VPN to work, this time I tried to reinstall the VPN but that doesn't work anymore. I started to uninstall updates (had 7 of them), when I got to it, KB3057839, the VPN began working again.

Connect to the router VPN using PPTP (Ubuntu)
Hello
As I mentioned in other post, I try to get the VPN works for my Ubuntu workstation. I'm not an expert of VPN, so I need help.
So far, people seem to agree that pptp is easier to config that IPSec (under Linux platform). Select the PPTP Protocol and add a user account for the Linksys router.
Now, the Linux part.
I have pptp-linux installation (it is the best client for linux pptp seams). I try to set it up, but I missed something relatd to coding or something.
I try to follow this documentation: https://help.ubuntu.com/community/VPNClient#PPTP
When I run this command: pon myvpn nodetach
I get the following error:
Using interface ppp0
Connect: ppp0 <-->/dev/pts/2
MPPE required, but not executed [v2] MS-CHAP authentication.
Connection down.Here is the log of the router:
15 Oct 21:51:02 2008 Client Remote System Log [] disconnect PPTP server.
Kind regards
Hello
Thanks for your help and this useful link.
I have change my configuration file and I managed to set up the pptp connection.
Here the configuration file that I use (for people with the same problem):
RemoteName until-vpn
LinkName until-vpn
ipparam entmd-vpn
Pty "pptp exemple.dyndns.org - nolaunchpppd.
name budderball
usepeerdns
require mppe
garbage-eap
/noauth
file /etc/ppp/options.pptpAlso, I change the contents of/etc/ppp/chap-secrets:
Budderball until vpn-based *.
With this configuration, I can launch the tunnel and communicate with the gateway and LAN.
Here the command line I use to establish the connection and than create road so that any request for 192.168.1.0/24 use the ppp0 interface.
sudo pon entmd-cpn debug dump logfd 2 nodetach
sudo route add - net 192.168.1.0 netmask 255.255.255.0 dev ppp0
Finally, by reading the documentation, I found a plugin for Network Manager. It's a work like a charm.
For ubuntu: sudo apt - get install network-manager-pptp
An installation, you must restart to 'activate' the plugin. (this is a bug)
You can use the network - manager to configure your pptp connection. I intend to post a wikiw on the Ubuntu Wiki page.

I looked at the configuration of your router RT-897VA once again, and I don't know if static NAT statements in there are supposed to work or not, but they won't because you have not specified any inside and outside interfaces.

Client VPN 3.7.2 on Redhat 7.3
Hello
Try to get the VPN 3.7.2 caces charged under Redhat 7.3 with kernel 2.4.18 - 10.
I downloaded the kernel.org kernel (2.4.18) and it located in usr. I have then run, do, make dep, and make install to create all the necessary files (including autoconf.h, version.h etc.).
I then installed the Cisco VPN client - taking of the default values for all the locations of files etc. The module seems to compile fine with no error messages, however when I try to run a 'start vpnclient_init' de/etc/init.d, I get the following:

Research on the release notes for the 3.7.2 looks like there may be a bet caveat with Linux which is the origin of the current problem. Take a look at this link http://www.cisco.com/univercd/cc/td/doc/product/vpn/client/rel3_7/clint372.htm#xtocid22

PPTP VPN or IPSEC for Android and iPAD
Being new on the RV180 (and routers VPN besides) I had trouble getting a VPN's, supporting my iPad and Android devices. However, I understand that an IPSEC connection would be a safer sollution. Unfortunately I can't find a clear statement anywhere to do it.
I found descriptions/parameters in the different RV180 of the setting of the (few) in mobile platforms. So far not managed to get the installation program.
Little help to start would be great!
Thank you very much.
Ronald
Hello Robert.
My name is Chris and I work at the Cisco Small Business Support Center.
The PPTP option will be much easier to install, and most devices have a built-in capability of PPTP.
The RV180 supports the IPSEC tunnels, but only for links from site to site or a remote user with the client software. Some of the other features of our support SSL VPN connections, which would allow you to use the Cisco Anyconnect client available for android, but SSL VPN is not a characteristic of the RV180.
On my Android (Droid X running Android 2.3.4) phone he built in VPN, IPSEC and PPTP client. Yours is probably as well, but if not there should be a few apps available.
If you decide to go with PPTP you can configure it like this on the RV180:
1. go to the router admin page and click on VPN > IPsec > VPN users.
2. check the box to enable the PPTP server.
3. complete the range of internal addresses for your customers to use PPTP (192.168.1.200 - 192.168.1.210 for example)
4. click on save.
5. Once you click on save, you should be able to edit the table of parameters of VPN client.
6. click on add, check enabled, enter a user name and password for the PPTP user to use and for the protocol type, select PPTP.
7. click Save to add the user.
Once this is done, you should be able to go into the settings on your Android device and add a VPN for PPTP connection. Fill in the same information you setup of the RV180 and you should be able to connect.
The server address will be the WAN IP of your RV180.
As far as IPSEC goes, the process is similar but a little more complicated.
1. on the router admin page go to VPN > IPsec > Basic VPN configuration.
2. choose the VPN client for peer type.
3. name connection (it is used on the router)
4. choose a pre-shared key to be used with this connection.
5. for remote WAN IP address, you can leave the default remote.com
6. for the Local gateway Type, you'll want to choose IP
7. to Local WAN IP select IP and enter the IP address of the RV180 (WAN IP)
8. for LAN Local, enter the local network for the RV180 ID (default is 192.168.1.0)
9. to the Local LAN subnet mask enter 255.255.255.0
10. click on save.
The steps above create a VPN IPSec tunnel using the default values of the router, which you can view by clicking on default settings under VPN > IPSEC.
Now you just set your phone. On my phone, I have an option for Advanced IPSEC VPN, but yours may be different, or you may need to use an application like a customer, if your phone does not have built-in IPSEC VPN.
On my Droid X, I want to go wireless and networks, VPN settings, Advanced IPSEC VPN, add a new virtual private network.
My phone uses models of connection, so be sure to choose one that fits your tunnel on the RV180 parameters.
Enter the RV180 WAN IP address as the VPN server, as well as the pre-shared key, install you on the RV180.
Make sure that all connection settings that you have configured on the RV180.
You will also be asked for an internal subnet IP address, and for this, you must enter the Local LAN and subnet mask, that you configured on the RV180 in steps 8 and 9 above.
I wish I could be more specific, but it seems that there are several different menus and options depending on what Android phone using your.
I hope that this helps, but if not feel free to respond and I'll try to explain.

I've set up a site to site VPN and I can't seem to get the VPN filter works. I've followed this document:
http://www.Cisco.com/image/gif/paws/99103/PIX-ASA-VPN-filter.PDF
I created an ACL and created an ACE with only traffic I want to allow. Then, I went to the site to site group policy and apply this filter. However, I can still ping remote network from a customer who should not be allowed. Remote network is 192.168.2.0/24.Here is my partial config:
permit Test access extended list ip 192.168.2.0 255.255.255.0 192.168.1.2 host
Trying to deny a range ip extended access listGroup Policy internal Test
Test group policy attributes
value of VPN-Filter Testtunnel-group Test_tunnel type ipsec-l2l
attributes global-tunnel-group Test_tunnel
Group Policy - by default-TestHello
First of all I would like to clarify that the group name used for one site to the other tunnel tunnel must be the ip address of the host "at least for the tunnels l2l static" it's tunnel-g were you must apply this "Test" group policy, configuring the filter seems perfect, but you must make sure that you apply the strategy of Group accordingly. Now, once you apply group policy to the correct you have to bounce the tunnel tunnel-g otherwise the new filter will not take effect, you can use the command "erase the crypto ipsec his counterpart x.x.x.x" generate some traffic and bring up the tunnel is again he should have the filter.
If you apply correctly and bounce the tunnel it will work.
You can check if the filter is applied with the command "show vpn-sessiondb detail l2l" and find the name of the ACL
Best regards, please rate.

NAT, ASA, 2 neworks and a VPN tunnel
Hello. I have a following question. I am trying to establish a VPN tunnel to a remote network used to be connected to our via a VPN tunnel. The problem is that the previous tunnel their share has been created for the x.x.x.x our coast network which will serve no more time a month, but is currently still active and used. As I'm trying to get this VPN tunnel as soon as possible without going through all the paperwork on the other side (political, don't ask) is it possible to make NAT of the new network in the network x.x.x.x for traffic through the VPN tunnel.
Something like this:
new network-> policy NAT in old x.x.x.x fork on ASA-> VPN tunnel to the remote network using x.x.x.x addresses
It is possible to add the new policy, but sometimes it can conflict with the former.

Using Cisco IOS Firewall VPN clinet
Hello
I configured RTR1 to support VPN Clients. RTR1 has a site 2 RTR 2 site VPN tunnel.
Customer VPN connected to RTR1 have RTR1 LAN IP connectivity. How can I get the VPN Client LAN to access the local network RTR2?
I've included the VPN Client LAN to be ecrypted in the VPN tunnel to the LAN RTR2 and Vice Versa. I also tried a static router configured on RTR2 for the LAN of Client VPN IP WAN RTR1 serving of next hop.
Still doesn't work is not for me. Any ideas?
Thank you
The other side added your remote VPN client pool to its configuration? The remote site must know its interesting traffic as well. Is RTR2 NAT'ing? Cleaned the configs for the two routers would help a lot.
