Cisco VPN :: 871 / How To Reduce IPSec VPN Connection Establishment Time
Aug 30, 2011
I set up an IPSec VPN with NAT-T between two cisco router 871. In particular one router acts as a SERVER and the other one as a CLIENT. All the traffic coming from the hosts connected to the CLIENT-router is sent over the VPN (no split tunnel). Everything works perfectly. The only problem is the amount of time the VPN takes to establish the first connection between the two routers. In particular it takes about two minutes. tell me if this amount of time can be reduced (with a partcular configuration instruction)? Or this is the minimum amount of time required for the first connection establishment?

I have set up an Any connect VPN client profile in ASA 5200. So, before creating an Any connect profile, i have uploaded the Any connect client image into flash (.pkg).It was successfully uploaded.While creating the profile, i have choosen the AAA server that i created (here its a RADIUS Server), specified the IP pool (192.168.2.x to 192.168.2.x),and assigned a group policy that i created.
So, in the client side i have installed the Any Connect VPN client in Win XP (version compatible with XP, same as the one that was uploaded into flash).Entered the IP of ASA in the "connect to" field of Any connect client. So, in the group field, it has auto detected the any connect profile which was created in ASA and i entered username and password and clicked on connect.It has authenticated the user credentials and has displayed the banner present in the group policy.
I accepted the banner, it displayed the security alert,clicked on OK on the alert, immediately after this it has thrown me a warning "VPN establishment capability from a remote desktop is disabled. A VPN coonection will not be established.".
When i click OK on the warning, it has thrown me another warning "Any connect wasn't able to establish a connection to the specified secure gateway.Please try connecting again".
When i searched for this warning, i got a work around which says "you will have to modify the "AnyConnectProfile.tmpl file", which can be found on the machine where the client was installed (its an xml file). You need to change the setting of "'WindowsVPNEstablishment' from "LocalUsersOnly" to "AllowRemoteUsers".Since i installed the any connect client in XP, i found this xml file in
"C:Documents and SettingsusernameLocal SettingsApplicationData CiscoCisco AnyConnect VPN Clientpreferences.xml" .
So, is this the same xml file where the change needs to be done? Because, i haven't found the setting "WindowsVPNEstablishment" in this xml file.

Is the WAG320N iPv6 compatable ? ,or could it be with a firmware update ?.Is the X2000 in the same boat in iPv6 terms as th WAG320N ?.Is there a way of retrieving "UPTIME" / "DSL connection time" information from the WAG320N and also line attenuation stats etc.Wouldn't need the above but poor isp needs keeping an eye on.

I am really not sure how to ask this question, but I will do my best. I have a Server running an application that I am connecting to via VNC app on my client. The app on the server is pushing 90mb down to the client, which is incredibly slow (3fps). I am curious if there is something that I can do/configure/verify to reduce the amount of data being pushed down?

I am trying to get a internet broadband connection through USB stick.. While speaking to the vendor. he said that they offer 3.1Mbps speed (no roaming charges)...all of this is understood...but they say that after 5GB of download the speed will reduce to 28Kbps....Can I know what do they mean by this.And how do I go ensuring how many GB have I completed my download.

I have a D-link Gigabit wireless router which works great but 1 particular wireless device of mine functions/works faster when i have a 100mbps Ethernet connection to it. Is it possible to slow down the wireless speed to a particular device?
Ideally i want my router to continue functioning as normal but i can't afford to have a 20m Cat5 cable running from my router through my hallway and into the living area. I want to slow the connection down to 100mbs for this one device.

I'm looking into upgrading our 4400 series controller to 5508's. Currently we have a few sites that have 8-9 4404 100AP controllers and I'm looking to condense these down to either 3 5508-500 or 5 5508-250 depending on cost. I'm wondering what a good port to AP ratio is for controllers with licenses that can handle over 100 AP's. I know the general rule of thumb is 25 AP's per port, but that seems to me to be 4400 way of thinking. I'm trying to also reduce the controllers overall footprint, i.e. ports on the uplink switch, power consumption, rack space etc.

I don't see any setting in the e4200 interface to reduce the transmit power. I only need to cover my small dorm room not the building. A friend has an e1000 and needs to do the same thing.

One of the file servers in your office is running out of space on the D: volume. There is unallocated space available on the same disk as the D: volume, as well as on other disks.What option should you choose to reduce administrative effort and minimize the chance of volume failure?

I'm having trouble with my internet the past few days, I'm connected to the internet via wifi and after browsing some minutes it will tell me unable to connect (using firefox and other explorers). In order to continue browsing I must refresh the page several times and it will load without pictures.I'm using win7 home premium and it's the only computer that presents this issue. I've tried pluging the computer directly to the router, but it gives me the same results. Also, I've scanned the computer for malware with MCafee, but it shows nothing.

I'm trying to setup a L2TP over IPSEC vpn connection on a PIX 501 that will use key sharing. In addition, I have a PPTP connection setup which allows connectivity. Two things, the L2TP vpn client I am using does not connect and times out. The second is that the PPTP client I use does connect, but cannot ping any resources on the network.
The config on the PIX is below:

I have remote access as I work at home on a government laptop that has Entrust( for security). My IP lapse time is set for 1 hour and every hour I am losing full connection due to having to sign back into Entrust. I need to be able to lenghten my lapse time on my work computer. My other two personal computers are fine with 1 hour as there is no Entrust on either of those laptops.....is it possible for me to change the lapse time to say 12 hours, 1 weeks, whatever??

I am using a desktop computer and have the router downstairs so I am using a wireless usb to connect to the internet. My router is a Linksys E1000 and the wireless adapter is a Netgear WG111v2. The problem is Every few mins I drop connection for may 5-30 secs and then the internet is fine. During that time it does not say I only have local connection or anything like that it constantly says I have internet connection even when I dont. It is very noticable when i am playing an online game on my computer. I will get a few mins in and then it will drop kicking me out of the game and by the time I get kicked out my Internet is reconnected and I can join again.

It is usually by a router or install a third party software without anyone saying if it works or not.
I have two connections at home. One is a Wifi ( public wifi for my village) that i use for my phone and the other one is a wired dsl. I have used both but not on the same time. I tried connecting them both ( phone have tethering) but I think they are interfering with each other making me lose connection. I am using vista home.
I have seen the merge connections( in network and sharing center) and i have seen this one [URL].. but I am a little bit wary of changing my registry.

At around 2:30 PM each day, the internet slows down, and it says its connected but with limited access. A few minutes later, it gets full connection again, but it is super slow, then the same cycle starts over again. It stops happening around 8:00 PM.
