Cisco VPN :: ASA5510 / Change Split Tunnel And Not Allow Access To Internet From Remote Location?

Mar 28, 2010

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.

Cisco VPN :: 877 - Easy Internet Access Without Split Tunnel

Apr 20, 2011

getting internet access via a easy vpn tunnel on a cisco 877 router. Basically we would like roaming users to be able to use the internet via the vpn rather than using a split tunnel. The reason for this is we have multiple sites that are tied down via external IP access lists for some services. We would like roaming users to be able to interact with these sites through the central router and use the routers external IP address to acess the secured sites. I know we can use a proxy but we also use some other non proxy bases services at these sites so would rather direct routed access.

Cisco VPN :: 5510 - Internet On Stick No Split-Tunnel With Limited Internal Access?

May 9, 2012

Is it possible to configure remote access (IPSEC client) to force all traffic through the tunnel (no split tunnel) yet still limit the internal hosts that can be accessed?
 
I have been asked to provide remote access (via ASA5510) with the following requirements:
 
  - the client should have unrestricted internet access via the ASA (the source address will appear to be the outside interface of the ASA)
 
  - the client should have access to only two internal hosts (192.168.10.10 and 192.168.44.10)
 
Is there a way to limit access to those two internal hosts, while still providing secured internet access? The only way I can see is to use an access list on another device (for example our core switch).

Cisco VPN :: ASA 8.2 / No Split Tunnel / NAT For Internet Not Working?

May 27, 2013

I'm configurig a VPN profile with NO split tunneling. The tunnel is working to the inside, but I'm not able to get internet access. Below are the NAT statements that I created.
 
nat (outside) 2 0.0.0.0 0.0.0.0
global (outside) 2 (ip address) 
 
I'm familiar with 8.6 nat statements, but with 8.2 it's not letting me put in the same commands.

Cisco Firewall :: ASA5510 - Web Interface On NAS From Remote Site Across VPN Tunnel?

Dec 3, 2012

I have two routers on my internal network.

10.10.199.106 is a Cisco ASA5510.

10.10.199.108 is a Sonicwall NSA 3500
 
The sonicwall handles our site to site VPN tunnels.  The Cisco handles our client to site VPN connections.
 
I have a unit that points to 10.10.199.106 (Cisco) for internet access.  All other clients on the network point to 10.10.199.108 (Sonicwall) for internet access.The device in question, a Synology NAS, is using 10.10.199.68 as it's IP address.
 
I'm trying to hit the web interface on the NAS from a remote site across our VPN tunnel.  The IP scheme on the remote end of the VPN tunnel is 192.168.72.0/24.
 
Going through the VPN, I can hit every object on the network that uses .108 (Sonicwalll) as it's gateway.  However, I cannot hit the unit that uses .106 (Cisco) as it's gateway. 
 
I added a route statement (using ASDM) that routes all traffic destined to 192.168.72.0/24 to the Sonicwall so it can send it back down the VPN tunnel.  If I'm understanding routing correctly, this should allow responses from NAS destined for 192.168.72.0/24 to go back down the VPN tunnel.

Cisco Routers :: Rv120w VPN Tunnel From Internet / Cannot Access Remote Servers

Feb 23, 2012

I have setup a site-to-site VPN tunnel between 2 sites using CISCO rv120w.Everything works fine; any PC on one site can access all systems on the other site and vice-versa.The issue I have is when I start a VPN connection another site on Internet using IPSecuritas.I can initiate a VPN to site 1 and site 2; but when connected, I can only access servers that are located into the same site I'm connected to; I cannot ping the remote site.The Range of IP addresses on the internet during my tests is 192.168.11.0 (I 'm using a Mac)

-Systems with IP 192.168.1.1 and 192.168.10.1 are bridges
-Systems with IP 192.168.1.2 and 192.168.10.2 are CISCO rv120w

Cisco VPN :: Remote Access VPN With Split Tunneling 2600xm

Dec 29, 2011

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.

Cisco VPN :: ASA 5510 / VPN Remote Access Split Tunneling?

Sep 27, 2012

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.

Cisco VPN :: 5510 - Remote Access With / Without Split Tunneling Using External DNS

May 6, 2013

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.

Cisco WAN :: 857 - How To Route Traffic Over Remote Location Internet

Nov 18, 2011

I have a customer which has a main location office and a remote one. Recently we interconnect their facilities using a local ISP service called Virtual Connectivity, which basically is a private network which can be accessed over aDSL or any other data circuit. They are using Cisco 888 routers to interconnect both sites.At the main site the customer also has an Internet circuit (with a Cisco 857 router)and he wants to remove the Internet circtuit from the remote site and provide them access over their main location Internet circuit.At the primary offices, we installed Cisco 2811 router as a gateway to route the Internet and remote network traffic over the required data circuit. Everything is working fine, but we can not access Internet from the remote location over the circuit installed a the main site. I understand this is a routing issue, since the traffic hits the main office network it does not knows how to reach the Internet. I am assuming this routing must be set into the main office Cisco 888 router (installed by the ISP to interconnect to their private cloud) in order to properly route it over the Internet circuit.Since I already have access over the Internet router and the gateway router at the main site, but not into the ISP router, is there any other way I can make this configurtion over the routers I already have access?

Cisco VPN :: ASA5510 Unable To Access Some Segments From Remote Access VPN

May 17, 2011

We have an ASA5510 and a few days ago we were unable to access some segments from remote access VPN, the problem was not the config.  A few hours later the problem was resolved on its own and I suspect we have an IOS bug.  This has happened a few times in the past and its becoming an issue. How can this be confirmed and which IOS should we upgrade to?  Prefer not 8.3 given the syntax difference

Cisco Firewall :: ASDM Access Through S2s Tunnel Group On ASA5510

Feb 7, 2012

For years now we've had an ASA5510 running an old version of ASA/ASDM (7.0/5.0) and couldn't access ASDM through a modern system with a recent JRE, so we didn't bother with this.
 
However, we've recently upgraded ASA/ASDM for purposes of adding failover and want to be able to access ASDM through our site to site tunnel. The site to site tunnel gives us access to the VLAN that the firewall is the gateway for, but not access to the firewall itself.
 
This side of the network is the 10.1.55.0 subnet, and that side of the network is the 192.168.1.0 subnet. I can ping devices on the 192.168.1.0 subnet, but not the firewall, (not that I really need to) and devices can ping me back. I can access ASDM through RDP or ssh into a server on the 192.168.1.0 subnet, but not directly from the 10.1.55.0 subnet.
 
This is the current config relative to the 10.1.55.0 subnet:
 
access-list trust_nat0_outbound extended permit ip 192.168.0.0 255.255.0.0 10.1.55.0 255.255.255.0
access-list untrust_cryptomap_600 extended permit ip 192.168.0.0 255.255.0.0

[Code]....

As far as I'm aware, the tunnel comes into the firewall through the untrust (public) interface, because that is the destination of the tunnel on the 10.1.55.0 subnet side.
 
What am I missing here that would allow asdm access through the untrust interface for the 10.1.55.0 subnet?

Cisco VPN :: ASA5510 Remote Access Vpn

Sep 20, 2011

I have access to my enterprise network through Cisco VPN (software) client and it goes through remote-access ipsec vpn setup on an ASA 5510. Everything works fine.
 
But now users that connect to the enterprise network have in addition need to access remote sites networks that are connected through the site-to-site VPN tunnels: IPSec tunnels between mentioned ASA5510 and remote ASA5510s and ASA5505s in branch offices.
 
there is NAT exemption rule that exempts networks 10.1.10.0/24, 10.1.20.0/24, 10.1.30.0/24.All traffic from local network 10.1.1.0/24 have full ip connectivity with all the networks in branch offices. The PROBLEM is that remote vpn clients can reach only local network 10.1.1.0/24, but not the remote networks.
 
The ASAs in remote branch offices has set up NAT exemption towards both local network 10.1.1.0/24 and remote access clients network 10.0.5.0/28, but as I said, it doesn't go.

I like to create a remote access VPN in our company. But it already has a site to site VPN.
 
1. Can we implement it with existing ASA?

2. How many users can be logged in at a time?

3. Is the currently available bandwidth sufficient at a high traffic ? Current bandwidth is 2Mbps (Expect maximum 30 users at a time)

4. How can we make authentication using active directory?

5. Can we use default VPN client in windows with ASA?

6. How can we monitor user’s activity while logging in using VPN?

Cisco :: Split Tunneling / ACL On ASA5510

Jul 16, 2011

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..

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?

Cisco VPN :: ASA5510 - L2TP Remote Access Disconnects After Few Hours

Nov 17, 2011

Have a few users on Vista/7 using Windows L2TP to connect to our ASA5510. It is reported that after a few hours the connection drops. From what I have seen this can be anywhere around 5-6 hours. Of course my connection will drop after an amount of time has passed and no traffic has passed the tunnel. But the users are adament that this drops during large transfers; i.e. not a timeout issue. Before I spend anymore time on this I just want to know if this is normal behavior for a remote access L2TP using Windows to disconnect on it's own after this amount of time. Never had a reason myself to remain connected that long, and when I did I used a site 2 site tunnel.

Cisco VPN :: How To Enable Split Tunnel On PIX 501

I then set up a split tunnel access list. Since I've set that up, I'm now able to ping internet based addresses (www.google.ca), but no longer able to resolve internal host names. I can ping the ip addresses, just name resolution no longer works.
