Cisco WAN :: 1941 - L2TP Client-Initiated Tunneling
Aug 12, 2010
I am trying to configure L2TP Client-Initiate Tunneling on a cisco 1941 with C1900 Software (C1900-UNIVERSALK9-M), Version 15.1(2)T0a, RELEASE SOFTWARE (fc1).
I have two 1941 and trying to tunnel the VLAN's across a point to point T1 connection. The reason for this is because one of the vlans on the remote end needs to be in a DMZ. The problem that I am having is that is allows me to setup the l2tp class but the pseudowire-class command is not available. Is there somthing I am missing? According to Feature Navigator L2TP Client-Initiate Tunneling is available in the IOS I am using

Is it possible to configure Layer 2 Tunneling Protocol (L2TP) over IPsec on a cisco router like 1921 ISR? This link shows basically what i want to achieve but instead of an ASA, i would like to use just a router with sec..

I am working with an ASA5505. I have configured a Remote Access IPsec Connection profile. This profile is configured to give clients a virtual ip address via DHCP as shown in this configuration example: url...When the DHCP request is sent from the ASA to the DHCP server, the hostname in the request is set to the name of the IPsec connection profile and a number. Is it possible to have the hostname set to the host name of the client that initiated the connection?Does the ASA support receiving a hostname as part of a IKE Mode Config Request?

I want a simple remote client-initiated VPN for employees to access corporate resources from home simultaneously with being able to access the internet. I am using CCP and seem to have several options including Easy VPN server, SSL VPN. I also can choose "Full Tunnel" or not.I have a 2911 router. I have a static range of internet IP addresses. The router is already functioning with inside to outside and outside to inside NAT, etc.

We have an ASA with software version 8.2(1) and ASDM 6.2 to use the VPN. We configure the anyconnect client with split tunnels for our vendors to access internal server and have access to the other resources in the web simultaneously. Windows XP client works fine however, the Mac OS x can only access the internal resource but not the web.we need to restrict the client to access and use only specific IP and http port.have internal and external DNS that are separated by ASA5520s all VPN terminate at the DMZ with192.168.xx.0/24 IP pool?

I'm having problem establish l2tp/ipsec vpn connection from Windows vista/7 vpn client to cisco 1921 ( ios 15.2 )
C1 --------> (internet cloud) ---------> (cisco 1921)----->LAN
Error that I'm retrieving is always the same: Error 789: "The L2TP connection attempt failed because the security layer encountered a processing error during initial negotiations with the remote computer"
But I'm able to establish l2tp/ipsec vpn connection to the same vpn server with my iPhone 4.
Below is isakmp debug log from lns router(cisco 1921) when I've tried to establish vpn with windows client. Anything useful from these logs to point me on the right direction to finally solve this problem with windows clients.
#debug crypto isakmp

I have configured the IPsec vpn between Cisco 877 and ISA server which is working fine and ok. But the issue is I have multiple subnet on the TMG "Treat Managmenet Gateway" side and only one subnet on the Cisco 877 side. I can only sending some subnet's traffics from Cisco 877 through the vpn tunnel to the other side which is TMG server and I have recieved teh timeout request for the rest of teh subnets.
However, if I initiated the ping from inside the ISA with different sources , I can reached the Cisco 877 and from then I can be able to send traffic.
So, the tunnel is up and active but it should be initated from ISA server to have a full connectivity.
Here is the IP sec configuration on Cisco side:
crypto isakmp policy 1
encr 3des
authentication pre-share

I have a Cisco ACE 4710 A5(1.2). Scenario: Inbound call from PSTN to SIP Phone. Call comes into the VIP and then load balances to sip server, the server then routes the call out via WAN to the SIP phone as below:
PSTN SIP Providor >(router)> ACE4710 > sip_server(s) > ACE4710 > (router) >SIP Phone
Note: Router is Cisco 3925 with "ip nat service sip udp port 5060" and Port 5060 mapped to the VIP of the ACE.If I put the sip server directly behind the router it works fine. From behind the ACE:
If I turn on sip inspect on the VIP the call setup (INVITE) and termination (BYE) work fine but the audio loops on the PSTN side from the mic to the speaker.If I turn OFF sip inspect then the audio is fine and mapped correctly but the call terminaton (SIP BYE) hits the VIP from the PSTN but never reaches the sip server.For ease and dianostics, I have turned off all sip servers except one meaning the load-balancer has only one server to choose from.SIP Call_id sticky is setup and seems to work, though irrelevent with one server only on test.How do I get the ACE to accept 'server initiated traffic' with sip inspect so it knows about the pending BYE when it comes back from the IP phone via the VIP?Config below, image attached. Bridged mode (also get the same result in routed mode)
access-list everyone line 8 extended permit ip any anyaccess-list everyone line 16 extended permit icmp any any

I have setup an ASA 5505 w/ Security Plus with three subnets. The subnets are as follows:
VLANSubnetWAN 10.0.0.80/29LAN192.168.1.0/24DMZ172.30.200.0/24 ]
The ASA is the gateway router at .1 for the LAN and DMZ networks. On the WAN network, the ASA occupies .85 and uses .86 as it's gateway to the Internet. Clients on the LAN are able to access the Internet without any troubles. I have a static NAT setup to map the DMZ server's 172.30.200.81 address to 10.0.0.81. I also have a general NAT that should allow other servers on that network to access the internet, but no machine at all on that network can route outside of 172.30.200.0/24. I used the packet tracer and had it trace traffic coming from the DMZ network to the Internet, and it did not show me any conflicts with any of the access lists or anything else. However, no matter what I do, I cannot initiate traffic from the DMZ and have it go out to the Internet successfully.I attempted to follow the directions in the article PIX/ASA 7.x and above: Mail (SMTP) Server Access on the DMZ Configuration Example; but I have obviously missed something, done something wrong, or perhaps the example assumes something about my configuration that I have not done. See the attached config file that I have scrubbed. I have removed VPN configuration information and other unnecessary parts of the config file to make it easier to read. I have setup an ASA 5505 w/ Security Plus with three subnets. The subnets are as follows: VLANSubnetWAN 10.0.0.80/29LAN192.168.1.0/24DMZ172.30.200.0/24 ]

I just moved our vpn over to using LDAP/DAP instead of the previous RADIUS we were using before. First of all, the group policy split tunnel is setup for Tunnel Network list Below Network list has a group of networks named "split-tunnel" setup with all of our internal subnets in it. Which seems to be working fine, users are hitting internal networks no problem.Where the issue lies is surfing the web while they are connected to the VPN.I think I know what one of the the issues are, I'm just not sure how to get around it. I have a proxy server setup that all domain traffic goes through say 10.20.30.40. That is obviously on our internal subnet. Our remote users has a policy on their laptops set to where if they can see/get to the proxy server then it pushes all traffic through there, however if they can not, it goes straight to the internet. That way they can still surf the web when they aren't connected to the domain network.
With the new DAP vpn policies, it seems as though they are trying to go through the proxy but failing so all http traffic is getting blocked on their computer as I can still ping say google.com...just can't open the web page.In my SALES-VPN access lists there isn't any acl that allows any traffic to 10.20.30.40(proxy server) so there isn't any reason their laptop would think it could get to it correct?I can't put an access-list SALES-VPN extended deny ip any any log critical at the end of the acl list because then it doesn't show up as an option to apply to the DAP since the acls have to be either permit or deny, not a mix.Also, if I just create an ACL access-list DENY-VPN extended deny ip any any log critical and apply it to the DAP *after* the SALES-VPN ACLs thinking all traffic would flow down as in go through all the permit acls first, and then hit the deny acl after, it just blocks all traffic.It almost seems that some traffic that isn't specifically being permitted by the permit acls is still getting through which is obviously not wanted. However, if I try to rdp into a server that isn't specifically permitted in the SALES-VPN acls it doesn't work so I'm kind of at a loss..

Is it possible to tunnel IPSec through a 6509 with an FWSM installed without the packets being interferred with?My question arises because myself and a colleague were attempting to form an IPSec tunnel in just this environment last week and no amount of resetting policies, key phrases etc would allow the tunnel to come up. The 2821 was complaining about Phase 2 not matching but the policies were definitely matching and configured the same on both ends. If there shouldn't be an issue with the 6509 and the FWSM then I will post configs from both ends. The 6509 is configured to all all ports through for the two IP addresses for now and is performing a one-to-one NAT for the PIX that is behind it.

I'm using an ASA5510 for remote access IP Sec VPN clients and it is configured for split-tunneling. The client computers are running Cisco VPN client software. All of the client computers running Win 7 work perfect, but the client computers running Win XP Pro cannot browse the internet, they only connect to the inside network.
1) Does XP Pro support split tunneling when using the Cisco VPN client software?
2) Does the ASA require a special config to support split tunneling with Win XP clients?

I am currently trying to configure an Easy VPN connection from an ASA 5505 to and ASA 5520. I have enabled split tunnelling and in the group policy defined the network to be tunneled but when I activate the VPN it tunnels everything from the host computer connected to the ASA 5505. I get no internet access. Have been trying to troubleshoot this for days.Hee are soe specifics, running version 8.2(5) on the 5505 and the 5520 and below is the local config on the 5505 for the Easy VPN:
vpnclient server **.***.***.**
vpnclient mode network-extension-mode
vpnclient nem-st-autoconnect
vpnclient vpngroup dbernstein-5505 password *****
vpnclient username dbernstein password *****
vpnclient ipsec-over-tcp port 10000
vpnclient enable
and the downloaded dynamic policy:
Current Server : 12.***.163.**
Primary DNS : ***.160.***.39
Default Domain : cisco.com
PFS Enabled : No
Secure Unit Authentication Enabled : No
User Authentication Enabled : No
Split Tunnel Networks : ***.160.***.0/255.255.255.0
Backup Servers : None

How to successfully run the dot1q tunneling on Cat4500 with Sup7L-E? I tried that on IOS XE 3.3 and newest 3.4. It is in feature navigator but i am not able to connect two access switching using trunk - only native vlan is translated. Apparently STP BPDU frames are dropped somewhere. I have the same configuration on 3750X with ip services licence and this works well.

my company has used Split Tunneling for all of our VPN uses, however we recently purchased 2 ASA5505s for use at various jobsites, and have been running into problems with Local Network Administrators blocking certain traffic that we need to operate. They allow full VPN connectivity to traverse their networks, so we are able to use our LAN Resources over the split tunnel no problem.
We have it set up as a Dynamic L2L Connection, and this ASA is operating flawlessly minus the traffic being blocked upstream by the network admin. Our VPN topolgy is Hub & Spoke. Below is excerpts from our config on how the VPN is set up: [code]
What we'd like to achieve is being able to pass ALL traffic (LAN & Internet) through the VPN tunnel, then be processed by the Hub ASA (192.168.9.1) on the other end. I am guessing crypto map + routing would have to be changed?
access-list to_hq extended permit ip 192.168.101.0 255.255.255.0 0.0.0.0 0.0.0.0route inside 0.0.0.0 0.0.0.0 192.168.9.1Disable NAT on Spoke. Is this how I would go about doing this??? We need ip address dhcp setroute so our ASA can find the other end and form the VPN tunnel, and I am not sure how this would affect things. [code]

I have some troubles configuring split-tunneling on ASA 5520.Number of remote users establish ipsec connection with ASA 5520 (in central office) using ubuntu vpnc-client.Split-tunneling is in use, to allow remote users to surf Internet using their ISP.The goal is to remove the possibility to ssh/telnet servers inside corporate LAN for remote users. [code]
There is nat enabled on interface, but there is special statement in nat0 ACL for 192.168.100.0 subnetwork access-list INSIDE_LAN_nat0_outbound extended permit ip 192.168.0.0 255.255.255.0 192.168.100.0 255.255.255.0.The problem is that remote users can easely ssh and telnet servers in INSIDE_LAN network. Whatever i put in INSIDE_LAN_in ACL, remote users still have full access to this network. Restrictions in REMOTE_split ACL don't work either.

I need to create a VPN and have split tunneling disabled, so that all traffic including internet traffic goes over the vpn back to the headquators and out that internet pipe or to the network. I will be using the Cisco VPN client software and connecting to a 2811 router running IOS ver 12.3(8r)T7. I am pretty new when it comes to these configurations

I would like to allow my remote users to access all resources behind the ASA and my remote branches. Here is my setup. ASA5510 as hub at data-center.
Internal network 172.21.x.x Directly connected
DMZ 172.22.1.x.x Directly Connected
Branch1 10.47.x.x L2L VPN
Branch2 10.47.y.x L2L VPN
Remote users 172.21.y.x L2TP Windows Client
I can access my internal resources connected to the ASA but not the DMZ or branch offices. Do I need routing and reverse route injection?

I have 2 computers in 2 different countries. The current country of residence (France) has some Internet restrictions that I want to bypass, so I need to pass all my Internet traffic to my home computer.The home computer is on Windows XP and the connecting computer is on Windows 7 (I also have a Windows XP laptop so that's not a restriction).
I created a vlan (or vpn?) using Hamachi, to have a static IP on the home computer. So now I have a connection to my home computer. The next step would be to direct all trafic through this connection. How do I do that? I tried using the windows wizards: on the home computer (server) I created a new incoming connections thingy and on the client computer I created a VPN connection using the hamachi IP. I finally succeeded connecting the two, but nothing happens. Once I connect to the VPN, I lose Internet connection, and with it the Hamachi connection. I don't think the server passes along the client's internet...

I am running OSX Leopard 10.5 and DDWRT is running on WRT54GL v24-sp2 (08/12/10) vpn.I have an SSH tunnel set up using DDWRT. So now I can surf securely when I am in a remote location.
The problem is after I am done browsing, I can't figure out how to close out the session in a proper manner. For example, I type ssh -p 2222 -N -D 8888 and it works with no problems. However, to kill the session I have to hit "CTR" and "Z". This is not the best solution because it leaves the session and port still open. how to tear down the session without using "ps aux" and then the "kill" command?

I've an ASA 5505, running at ASA 8.2(2). I'm using ASDM 6.2(5).ASA is set up with Split Tunneling and it works perfectly.However, for a few users, I want all traffic, including Internet traffic, routed through the ASA.The spesific users IP address at internet should then be the same as ASA Outside address, not the client local address.The question is therefore:How to simple override the split tunneling at user level?Alternatively set up an "tunnel all" group policy for the specified users?

I want to get a Cisco router for central point of 100 GRE tunnels and total 10G traffic coming from those tunnels. I used 6500 but its CPU became high in less than 2 G traffic. Can you identify me a suitable router for this purpose. I think the router must process the GRE in hardware.

My cisco router (2600XM) is connected with the core switch with the vlan 6, behind the core switch there are many vlans and a mac web server (also DNS and DHCP). I am using remote access VPN with split tunneling (i would like to keep it instead of Dynamic interface). I can connect to the VPN and ping the cisco router, the core switch and the web server (by using telnet from the router to the switch and then to the mac but i can't access directly from the VPN client) but from the web server i can't ping the VPN client.I tried many things such as, adding the 192.168.1.0 to the access list for the intersting traffic or allow the tcp port 8080 but i think my mistake is related to the routing and NAT but i can't figure it.

I have several RV082 routers in production, most of them on IPv4-only access. I want to roll out IPv6 on all these networks and have set up a test environment for this.I did start with a factory-defaulted router with a fixed public IPv4 address. IPv4 network access does work as expected.With the 6to4 option disabled, the RV082's IPv6 routing table contains several entries for local addresses, but not public ones, as expected. When enabling the 6to4 transition function as described in SBKB article #567, three new entries are created: [code]
With the router's diagnostic ping function I can ping the next 6to4 relay on IPv4 (192.88.99.1) and IPv6 (2002:c058:6301::). But I cannot ping that next hop address given as default route (::c058:6301).The RV does advertise routes with the correct 6to4 prefix on the LAN side, and the clients connected to it configure themselves with appropriate addresses. However I was unable to ping any IPv6 both in the 2002::/16 as well as in the 2000::/15 range from any system on the RV's LAN side. When trying to add a static route which routes the 2000:: prefix with prefix length 15 to next hop 2002:c058:6301:: with metric 1, I keep getting the message "Please input IPv6 Address with correct format!"could there something wrong with this default route? How can it be changed? And what is the problem with the route I am trying to add?

I have a cisco 2821 router. I currently have it setup to accept vpn connections from a cisco client which uses the 172.16.4.0 subjet for vpn connections. I also have nat overload setup for my local lan of the router so my internal servers on the 172.16.3.0 subnet can reach the internet. Every thing works great for that setup.However I have tried several methods I found for split tunneling and they have weird problems with the nat overload in place. If I take away nat overload the split tunneling works. If I take away split tunneling the nat overload works. I can't seem to get them to work at the same time.Config is below. This is the vpn/nat overload config with no split tunnel.

I have added these networks to the split-tunneling ACL's and added NAT exemptions for those networks.This doesn't seem to work.
