Cisco VPN :: ASA 5520 - Mac OS X Client Can't Use Split Tunneling
May 10, 2011
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 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.

Is it possible with ASAVPNSERVER 5520 and an EasyVPN 5505 Client to have the client do split tunnel to a single public IP address? Both devices are on 8.2(5) 33. Could you possible provide sample config for split tunnel?

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'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

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 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

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.

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 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

I have configured my ASA5520 to act as VPN server. It accepts connections from the internet and then it authenticates the user to a Windows 2008 Server via Radius.Everything works fine if I use the VPN client embedded in Microsoft Windows. Conversely, if I try to configure Cisco VPN Client, I cannot find where to define the PSK string.

I have made the following change to my ASA 5520 using ASDM to try and force VPN clients to use a self assigned certificate from the ASA. I made the following changes Remove Access VPN > Certificate Management > Identity Certificates > Add Certificate.Then I made the following change.. Remote Access VPN > Network (Client) Access > IPSec(IKEv1) Connection Profiles > Connection Profile > Edit > IKE Peer Authentication > Pre Shared key and pointed the identity certificate to the one I created in the step above.Having made this change I am still able to VPN without a certificate configured in authentication settings.I was expecting that the VPN would attempt to issue the self assigned cert to client machine?

I have remote branches that connect to the corporate office as a site-to-site VPN. Now the clients at the branch are getting an application that is using an unsecured port (tcp/23). I would like to use a set of ASA 5520's that I have at the corporate office, with the AnyConnect license on them. I want the client machines to establish a tunnel from the client to one of these ASA's. The ASA' then would have a connection to the VLAN that the receiving server is housed on. The trick is to just establish the tunnel from the client to the ASA that will allow the IP of the client to not be translated. So I would use the ASA as a security 'pass-through' for the clients that use this new application.

My basic question is, does Cisco VPN Client allow two simultaneous VPN connections at once?I want to set up the following:User Client (Remote Access VPN via Internet)--> Head Office ASA 5520 A/S Pair --> (Remote Acces VPN via Internet) --> Branch Office ASA 5510S+ A/S Pair,So, in order to access the branch office system, the user must:Connect to Head Office ASA peer via Cisco VPN Client (user/password authentication),Head Office ASA peer gives a private 172.16.1.x IP, and is configured to route all requests to Branch Office's public ASA IP via it's own public IP address. Once Head Office VPN established, user establishes a SECOND VPN tunnel from Cisco VPN client (user/password and cert-based auth).

I currently have a Cisco 5520 ASA which is up and running and the users are able to connect to Anyconnect to VPN into the network. However, users plugged into the internal network inside the ASA are unable to connect to the vpn address and download the Anyconnect Client. I think this may be to do with reverse NAT missing?

All routing in the network is Ok My customer want to access a server @ ip 10.194.70.1 in https on the interface Interco with his nat address as 10.97.0.11 .This server must be accessible with the address 10.97.0.11:443 from interfaces inside, outside and other sites.And source address must be nated with original destination address 10.97.0.11 to be redirected on 10.194.70.1.
