EZVPN public internet split tunnel with dialer interface
I have a job on where I need to be able to use EZVPN with split tunnel but still have access to an external server from the corporate network as the external server will only accept connections from the corporate public IP address.
So I have not only included the corporate C class in the interesting traffic but also the IP address of the external server.
So all good so far, traffic for the corporate network goes down the tunnel as well as the IP address for the external server.
Now comes the problem, I am trying to send the public IP traffic for the external server out of the corporate network into the public internet but it just drops and does not get back out the same interface into the internet.
I checked out this procedure and it did not help as the route map counters do not increase with my attempt to reach the external router.
http://www.cisco.com/c/en/us/support/docs/security/vpn-client/71461-router-vpnclient-pi-stick.html
And to just test the process, I removed the split tunnel and just have everything going down the tunnel so I can test with any web site. I also have a home server on the network that is reached so I can definitly reach into the network at home which is the test for the corporate network I am trying to reach.
Its a cisco 870 router and here is the config

Thanks for the response.
Not sure how that would help as I can connect into the internal network just fine, but I want to hairpin back out the interface and surf the internet from the VPN client. The policy route map makes the L10 the next hop and it has NAT.

CISCO ASA 5505 Split Tunnel DNS with Site to Site VPN
I have a working configuration for Site to Site VPN between our head office and a private AWS VPC instance.
The tunnel is active and I can ping the IP address of the remote network and connect to the remote machines using the IP address, but we need to use the FQDN and not the IP. We have a DNS server set up in AWS for any DNS queries for the remote domain name.
My question is whether or not the ASA 5505 supports a DNS split tunnel for Site to Site VPN and how it can be configured.
I can not find where I can interogate the DNS query to be redirected to the VPN tunnel when our domain name is used in a DNS query. Thus, any pings I try with the FQDN of our servers in AWS are failing as they are going to the default DNS, which is the internet.
Can any one point me in the right direction on how to configure this DNS rewrite so that we can access our AWS private cloud using FQDN from our AWS domain rather than an IP address?Jose, your fix to problem 1 allows all access from the outside, assuming you applied the extended list to the outside interface. Try to be more restrictive than an '...ip any any' rule for outside_in connections. For instance, this is what I have for incoming VOIP (access list and nat rules):
access list rule:
access-list outside_access_in extended permit udp any object server range 9000 9049 log errors
nat rule:
nat (inside,outside) source static server interface service voip-range voip-range
- 'server' is a network object *
- 'voip-range' is a service group range
I'd assume you can do something similar here in combination with my earlier comment:
access-list incoming extended permit tcp any any eq 5900
Can you explain your forwarding methodology a little more? I'm by no means an expert on forwarding, but the way I read what you're trying to do is that you have an inbound VNC request coming in on 5900 and you want the firewall to figure out which host the request should go to. Or is it vice-versa, the inbound VNC request can be on port 6001-6004 ? -
Split Tunnel VPN and routing public ip traffic
Hi Everyone,
I have my split tunnel vpn working well but I need to make an adjustment. We have a few systems in the "cloud" and we only allow access from our corporate WAN IP to those servers. I need to be able to access those servers via VPN connection to the office. I added that public IP subnet to my interesting traffic and the vpn client is sending the traffic across the VPN as expected. The issue is that it somehow drops out inside the firewall it seems. Almost like it doesn't know how to route that request back out to the internet using it's own default gateway. Any thoughts as to what I may be missing, here is some of the relevant code

Let's do it this way, this should fix the problem. Put the NAT command the way it was as follows:
nat (Outside) 1 10.1.10.0 255.255.255.0
Now we add a NAT0 for the Outside interface. You can reuse the ACL we made if you want or make a new one, your call since you have to administrate it.
no access-list VPN-NAT
access-list VPN-NAT0 permit ip 10.1.10.0 255.255.255.0 10.0.0.0 255.0.0.0
nat (Outside) 0 access-list VPN-NAT0
Now, this should properly NAT the traffic going to the Internet while excluding the traffic destined for your 10.0.0.0/8 subnet using the Nat 0.
Sorry for the round about fix, but that should take care of it. -
Remote Access VPN, no split tunneling, internet access. NAT translation problem
Hi everyone, I'm new to the forum. I have a Cisco ASA 5505 with a confusing (to me) NAT issue.
Single external IP address (outside interface) with multiple static object NAT translations to allow port forwarding to various internal devices. The configuration has been working without issues for the last couple years.
I recently configured a remote access VPN without split tunneling and access to the internet and noticed yesterday that my port forwarding had stopped working.
I reviewed the new NAT rules for the VPN and found the culprit.
I have been reviewing the rules over and over and from everything I can think of, and interpret, I'm not sure how this rule is affecting the port forwarding on the device or how to correct it.
Here are the NAT rules I have in place: (The "inactive" rule is the culprit. As soon as I enable this rule, the port forwarding hits a wall)
nat (inside,outside) source static any any destination static VPN_Subnet VPN_Subnet no-proxy-arp route-lookup
nat (outside,outside) source static VPN_Subnet VPN_Subnet destination static VPN_Subnet VPN_Subnet no-proxy-arp route-lookup
nat (outside,outside) source dynamic VPN_Subnet interface inactive
object network obj_any
nat (inside,outside) dynamic interface
object network XXX_HTTP
nat (inside,outside) static interface service tcp www www
access-group outside_access_in in interface outside
route outside 0.0.0.0 0.0.0.0 xxx.xxx.xxx.xxx 1
Any help would be appreciated.Try by changing the nat rule to nat (outside,outside) after-auto source dynamic VPN_Subnet interface

Cisco AnyConnect SSL VPN no split tunnel and no hairpinning internet access
Greetings,
I am looking to configure a Cisco ASA 5515X for Cisco AnyConnect Essentials SSL VPN where ALL SSL-VPN traffic is tunneled, no split tunneling or hairpinning on the outside interface. However users require internet access. I need to route traffic out the "trusted" or "inside" interface to another device that performs content-filtering and inspection which then egresses out to the internet from there. Typically this could be done using a route-map (which ASA's do not support) or with a VRF (again, not an option on the ASA). The default route points to the outside interface toward the internet.
Is there no other method to force all my SSL-VPN traffic out the inside interface toward LAN subnets as needed and have another default route point toward the filtering device?
OR
Am I forced to put the ASA behind the filtering device somehow?Hi Jim,
You can use tunnel default route for vpn traffic:
ASA(config)# route inside 0.0.0.0 0.0.0.0 <inside hop> tunneled
configure mode commands/options:
<1-255> Distance metric for this route, default is 1
track Install route depending on tracked item
tunneled Enable the default tunnel gateway option, metric is set to 255
This route is applicable for only vpn traffic.

Thanks!!!Hi,
When you are using Full Tunnel VPN (which is the default setting) you will have a couple of things that you need to configure on the ASA.
First, the ASA by default won't allow traffic to enter through an interface and then leave through that same interface. This is what essentially happens when the traffic from the VPN Client comes to the ASA and then heads out to the Internet. In your case the traffic comes through the "outside" and leaves through the "outside" interface.
You will need this command
same-security-traffic permit intra-interface
You can check if its enabled at the moment with the command
show run same-security-traffic
Second, the VPN users will need to have NAT configuration just like any LAN users behind the actual ASA. So you will essentially have to configure Dynamic PAT for traffic from "outside" to "outside"
You can accomplish that with the following configuration
object network VPN-PAT
subnet 10.4.1.0 255.255.255.240
nat (outside,outside) dynamic interface
I would imagine that this should do it for you to be able to connect to the Internet and to the LAN network when the VPN is active.
Hope this helps
Let me know how it goes.

Help with Easy VPN client split tunneling.
Can someone please help me with my config for Easy VPN Client split tunneling. At the moment when the VPN is up I have NO access to the Internet from any host.
Here's what I am attempting to do. I want only certain host to route all there traffic thou the tunnel and the remaining host to use the default route.
I created an object-group and access list with the hosts I want to route thou the VPN :-

access-list 111 permit udp any any eq 3074
access-list 111 permit tcp any any eq 3074
access-list 111 permit udp any any eq 88
I Then applied the access list to the Virtual interface of the VPN in both directions:-
interface Virtual-Template1 type tunnel
no ip address
ip access-group 101 in
ip access-group 101 out

Now when I connect to the VPN I have no access from any host to the Internet either thought the tunnel or not.
I must be doing something very wrong. Much appreciate any help.

Help With split tunneling and multiple subnets behind asa
Hello All,
our vpn clients can no longer access internet while connected to vpn.
I was hoping I could get an answer on here for an issue we are having. let me explain this with as little words as possible.
here was old network layout:
ASA
192.168.1.1 ----> the rest of the internal subnet (was only subnet in network)
now
ASA 3560
192.168.254.1/24 ----->192.168.254.2/24-->192.168.1.1/24
192.168.2.1/24
so what we did was route from 3560 to asa so we would be able to have multiple subnets since our asa has base license.
Our vpn with easy connect worked with our split tunneling before and now we made the change above and it no longer works. Can someone help me out as to why it no longer works and what changed need to be made to make it work.
Thank you.

VPN split tunneling does not work with filtering enabled
I restricted our Windows VPN clients to reach only certain IPs and ports using filtering in their group policy. It works but I would like to add split tunneling for client's local Internet access. I temporary disabled filtering, unchecked the 'user default gateway on remote' box in properties of Windows VPN client, configured networks to be tunneled and it works. The moment I configure filters, my split tunneling does not tunnel the networks - they are not listed in Windows 'route print'. I change filtering to inherit or NONE and reconnect VPN and the tunneled networks show up again. I change filtering to a simple testing ACL/ACE and reconnect and they are gone again. Can I have split tunneling and filtering working simultaneously? Any help would be appreciated.
I'm not aware of any method named tokenize and there isn't one listing in
the alphabetic list of methods in the J2SE API. Perhaps you were thinking
of java.util.StringTokenizer, whose API contains this note:
StringTokenizer is a legacy class that is retained for compatibility reasons
although its use is discouraged in new code. It is recommended that anyone
seeking this functionality use the split method of String or the java.util.regex
package instead. -
VM with remote access VPN without split tunneling
Hello experts,
I have customers who require to use VM in their laptop. These users also require to VPN to Corporate network to do their job. However when they do remote VPN to corporate Network (ASA VPN concentrator) from their VM host machine, they loose their access to their VM guest machines. This problem was not happening when they used cisco VPN client which has gone end of life and support as of end of July 31, 2012. In Cisco VPN client (IKEV1) if we set the protocol to udp they had no problem to keep their connectivity to VM machines while connected to corporate with remote access VPN. However this feature does not work in new Cisco VPN client which is called AnyConnect. ( NOTE: I am using IPSEC IKEV2. NO SSL at this time).
My Question to Experts:
1. Was the ability to maintain connection to VM guest machines, while connected to VPN without enabling split tunneling a security flaw in the old cisco VPN client?
2. Is there a way to maintain connectivy to VM machines installed in a computer and still connect to remote access VPN concentrator through host machine? (My question is about AnyConnect client only using IPSEC IKEV2 and I do not want to enable split tunneling)
Thanks for your help,
RaziDid you figure this out?

Script for internet connect with dial up modem, check email & log off
I am looking for a script to connect to the internet (with dial up) external apple modem, then check email and then log off and disconnect. I don't want any other applications opening internet connect? A would use this script file with ical and could have my email checked and open up in the morning before I leave for work....being that we have dial up the entire process of connecting to the internet and checking email is time consuming. Any help is greatly appreciated. thks
You need some additional logic in there - as written, the script will launch mail, then immediately disconnect the internet connection.
At the very least you need to add a delay before disconnecting to allow for Mail to download awaiting messages.
Since you cannot predict how long a delay you'll need, a better approach would be to query Mail.app and wait until it's idle, like:
tell application "Mail"
launch -- doesn't need to be frontmost
check for new mail -- get all mail
repeat until (get background activity count) = 0
delay 2 -- wait 2 seconds before checking again
end repeat
end tell
In this way the script forces a check of new mail (don't assume that Mail.app is set to auto-check, especially for dialup users who often compose mail offline and may have automatic checking disabled), and it hangs around until Mail.app has finished downloading all the messages. -
Can you help? Two dialer interfaces with IP SLA for default route failover - issues
I have an issue with a Cisco 2821, it has an ADSL2+ HWIC whose ATM interfaces is linked to dialer 1 and a Gi0/1 interface with a pppoe client which is linked to dialer 2. Both dialer interfaces are up with their respective IP addresses. If the ADSL on dialer 1 fails i want the IP SLA to kick and and replace the default route for dialer 1 with one for dialer 2.
This config works if you manually shut down the dialer 1 interface, it injects the default route for dialer 2 and then when you unshut the interface, the default route for dialer 1 comes back. The problem i have is if you take out the cable for the ATM interface and take it down, it does not take the route out the routing table and the default route for dialer2, which works if you just shut down dialer 1 does not appear.
whats the difference between shutting down dialer1 and it fails over the default route and taking the cable out then it does not?
Here is my config, i'm sure its something simple i'm doing wrong, can anyone help???

endSure that EEM can shut/unshut interface...you have "event track" in EEM for monitoring track events...for example:
event manager applet test
event track 1 state down
action 1.0 command "enable"
action 1.1 command "conf t"
action 1.2 command "interfac dialer 1"
action 1.3 command "shut"
action 1.4 syslog "Dialer 1 down!!!"
action 1.5 end
This would be an example from head :)
You would need another EEM similar to this one for unshutting interface with "event track 1 state up" for bringing interface up again.
Again as I said you would need to test this before putting in production and you would maybe need to tweak this a little bit acording to your needs...

Still after update to 5.0.1 same problem with the 4S with dial out, connecting to internet, echo in reception. It is the second phone.
Try deleting the account(s) you're having problems with, resetting your phone (hold on/off and home buttons simultaneously 10-15 seconds until Apple logo appears, release buttons and wait for it to restart), then add back your mail accounts. I've read that this has worked for some.
