Cisco VPN :: ASA5510 / Win XP Pro - Split Tunneling
Aug 23, 2011
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 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..

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

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.

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 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'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?

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 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.
Current configuration : 2236 bytes
!
version 12.4
service timestamps debug datetime msec
service timestamps log datetime msec
service password-encryption

I have a ASA 5510 configured for IPSec remote access VPN.It works nicely and can see the private LAN behind the ASA.My problem is that I have other networks connected to this ASA via site-to-site tunnels that I would like to open up to remote access.
I have added these networks to the split-tunneling ACL's and added NAT exemptions for those networks.This doesn't seem to work.

(ASA5510, ASA version 8.2(3)) I have set up split tunneling for one of our suppliers. When testing the setup the local computer with the VPN Client connects to the dedicated services it has access to behind the ASA, and the local computer can ping any computer on the local LAN and it can also access the internet and webpages on the local network
But the supplier complaints that he cannot run a local Navision session on the remote computer while connected to the VPN tunnel. I am not able to run a test that mirrors this.
I have followed the descriptions in document ID: 70917 in setting up the split tunneling, and as far as I can see, the setup works. But is there any restrictions laid on the local computer running the VPN Client in what services on the local network it can connect to?

I've set up a remote access group for Anyconnect on a 5510 running 8.4.5. Our company security policy prohibits split tunneling, but this particular location has no internal DNS (so I have to use a public DNS like google or something). How do I get this to work, I'm assuming I need to do a NAT exemption but I'm not sure how this would look, especially under 8.4.5.

8 Port G Switch = SBS2008 / Win2003 with Citrix / Win2K8 Management Server - plus a couple of desktops for Gig to server accessIs it possible to configure a PIX 501 to allow internet access for a Cisco VPN Client 4.8 without Split tunneling.The idea would be to have all raffic traverse the tunnel, be routed out the local WAN link on the PIX and then have the reply be forwarded back to the client over the IPSec tunnel.

I've just deployed a SRP527W that I've had lying around for a while.Everything on the unit runs as well as can be expected, however I have a requirement to run split tunneling for VPN users.
Currently the only route that the VPN client receives is a default route. I noticed that on site to site VPN's and GRE tunnels you can specify secured routes, however I can't find anything that relates to the VPN remote users. This can be done on IOS without a problem but would be nice for the SRP.
I'm running the latest firmware 1.01.26, so if I haven't overlooked something would this be likely for a future release?

I run a cisco asa 5510 and I want to know how to configure the asa to let some of AAA users navigate through the remote gateway (with remote public ip).I've already configure ipsec, ssl group policy, and I know I can disable split tunneling. I do it but remote users (connected with ipsec vpn cisco client) could access remote LAN but when they try to navigate through internet, there's no ip connection.
Do I have to configure some NAT ? I've already configure some rules to let the vpn ip pool go to the internet.I just want my remote users to navigate on internet through the vpn tunnel and the remote gateway (the asa).Do I have to setup some proxy ?

Trying to setup split tunneling over Site-to-Site (Gateway To Gateway) VPN between RV082 and Win 2008 server. Tunnel seems to be ok, I can ping/access by IP hosts from both ends. But I can't get split DNS to work. Here is the setup
10.10.100.2 is the DNS server for xyz.local zone. It is at remote network.
The tunnel and routing work properly. I can ping 10.10.100.2 either from RV082 (system management - diagnostics) or from hosts at local network.
Moreover, I can run nslookup on a host from RV082 side (local network), set 10.10.100.2 as server to be queried and test dns resolution. names of hosts from xyz.local are resolved correctly. But. If I use nslookup on host to query RV082 as a DNS server and query for a host from xyz.local it responds that xyz.local is nonexistent domain. The same result I get trying to resolve/ping same name on system management - diagnostics page. Resolution of names from xyz.local fails. But Internet names are resolved
just fine.
I've tried to reboot the router, connect/disconnect the tunnel, set Domain Name fields of split DNS configuration pagein different ways including fqdn of hosts from xyz.local No effect. Just the same situation.

I have successfully setup the AnyConnect VPN (connecting to our ASA5510) and have split tunneling configured. My remote users can access inside LAN servers as well as the Internet from their remote location. What I would like to know is is it possible to change the split tunnel and not allow access to the Internet from the remote location but force the remote client to go through the VPN and out our internal edge firewall to the Internet? Basically I need my remote clients to access the Internet but I would like for their Internet traffic to go through the VPN and out our edge firewall. This will allow the same security as if they were sitting in the office.

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.

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.

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?
