VPN GRE QOS tunnel how do i ?

i have two sites connected by VPN, i run a GRE tunnel between both so that eigrp works. This is fine for data but voip is poor.
I would like to prioritorise the voip traffic over the GRE tunnel but can't find any examples where this has been done.
Has anyone done this?

Mark the packets coming into the router at the LAN interafce. Add the command QOS pre-classify to the Tunnel interface and Crypto-map. At this point you can either enable Fair-queueing on the WAN interface or build a Service policy and add that to the WAN interface. Fair-queueing, by default will use the precedence bits to prioritize traffic. So the packets will already be in the correct order (prioritized) by the time they enter the tunnel. You can also use a service policy and guarantee bandwidth to certain classes. The policy also uses Fair-queue to prioritize the highest TOS bits first.
In the attached sample:
#Policy "LAN" would go on the LAN interface
interafce FAST0/0
service-policy input LAN
#Policy "QOS-128-Port" would go on the WAN interface
interface s0/0
service-policy output QOS-128-Port
*You cannot have fair-queue enabled on an inbound service policy

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
With Regards,
Safwan

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.
HTH,
Shetty

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 :-
object-group network VNPCLIENTS
description HOSTS ALLOWED ACCESS TO THE VPN
host 192.168.3.204
host 192.168.3.42

access-list 1 permit 192.168.3.0 0.0.0.255
access-list 101 remark Hosts allowed access to VPN
access-list 101 permit ip object-group VNPCLIENTS any
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
tunnel mode ipsec ipv4
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.
Thanks
Gordon

I do not see where to enter IP addresses in the Open VPN setup. Also, how can I set it up so that I can choose different servers in the same way as I can currently choose them with my VPN app but for PPTP?

I think I have it working on my iPhone 5. But, I do not see how I can control the exit point that I would like for the VPN. Are all the exit points shown in the VPN setting now going to work with Open VPN, or do they remain PPTP? If I am reading correctly, they look like they remain PPTP. If I cannot control the exit point for open VPN, which exit point is the default in the profile you provided me?I note that Open VPN Connect does not work with any of the new 64 bit devices like the iPhone 5S, the iPad Air, and the new iPad MIni. Is there any chance that you guys will come up with an update for your app so that open VPN can be made to work on all iOS devices? That would be nice, particularly if the Open VPN Connect app does not give me a choice of exit points.Thanks,

Just a quick note to tell you that Open VPN has updated their app so that it is compatible with 64 bit ARM devices like the iPhone 5S, the iPad Air, and the iPad Mini Retina.That does not resolve the problem of how to easily choose among the various possibilities for the exit server. We need to find an easy way to choose.

Thank you for trying the new Firefox. I'm sorry that you’re unhappy with the new design.
I understand your frustration and surprise at the removal of these features but I can't undo these changes. I'm just a support volunteer and I do not work for Mozilla. But you can send any feedback about these changes to http://input.mozilla.org/feedback. Firefox developers collect data submitted through there then present it at the weekly Firefox meeting
I recommend you try to adjust to 29 and see if you can't make it work for you before you downgrade to a less secure and soon outdated version of Firefox.
Here are a few suggestions for restoring the old design. I hope you’ll find one that works for you:

What does VPN DO? And how to use it ?

What does VPN DO? And how to use it?

http://en.wikipedia.org/wiki/Vpn
Or Google 'what is a vpn' or 'how to use a vpn' many people have explained this better than me.
In short it wraps your traffic in to an encrypted link to a server (normally on the internet). Then the traffic leaves that server & goes onto the public internet. It is possible for the link to reveal information about you, but a VPN can protect you on open wifi or on bad networks etc.
Sometimes the VPN terminates inside a corporate network, so users can do work at home securely.
It is similar to using https for web browsing (secure http makes traffic difficult to intercept & read).

URGENT - tag-switching over gre-tunnel - how ??

hi,
my problem is that i want to connect two pe-router
over a gre-tunnel.
this is because between the two pe´s i unfortunatly have two cisco828 router as modemrouter inbetween which do no tag-switching.
so i decided to use a gre tunnel between the two pe´s to do tag-switching.
but if i want to forward packets greater than 1492 bytes and the df-bit is set - no chance.
here is the figure and config of the two tunnels:

please help - thanks

Here's at least two options you could try:
1) Lower the MTU on the tunnel-interface and let PMTU on the endpoints take care of the fragmentation. This could have some serious implications all depending on the systems and applications/protocols used on the network, but in most cases it'll work just fine.
2) Simply remove the DF-bit on incoming packets to the router and lower the MTU on the tunnel-interface and let the router do fragmentation regardless of what the endpoints says. Since you have a 3640 on each end and 828's in the middle, I think it should be capable of this..
You should do a MSS-modification as well in both cases.
Change the MTU like this:
interface Tunnel65052
ip mtu 1488
tag-switching mtu 1500
Then you have set all IP-packets to maximum 1488 bytes (including headers) and let there be room for 3 MPLS labels...
At least I think it should behave like this... please don't kill me if i'm wrong.. :)
Remove the DF-bit with route-map's on the inside interfaces:
interface FastEthernet1/0.100
description inside interface
ip policy route-map clear-df
ip tcp adjust-mss 1424
route-map clear-df permit 10
set ip df 0

AnyConnecy VPN and Split-tunnel ACL - Strange...

Hi,
I have ACL as follows and applied on AnyConnect VPN group as split-tunel value ACL.
access-list SPLIT-ACL extended permit tcp host 192.168.200.63 172.16.1.0 255.255.255.0 eq www
access-list SPLIT-ACL extended permit tcp host 192.168.200.63 172.16.1.0 255.255.255.0 eq https
When I connected with AnyConnect client, I can ping to 192.168.200.63 and also telnet to port 80. However I can not telnet to port 443. Strange thing is I do not see any hits on above ACL, morever I'm wondering how cam the ICMP is working and why it does not stop on this ACL..?
Phase: 4
Type: ACCESS-LIST
Subtype:
Result: DROP
Config:
Implicit Rule
Additional Information:
Forward Flow based lookup yields rule:
in id=0x78e03140, priority=11, domain=permit, deny=true
        hits=113713, user_data=0x5, cs_id=0x0, use_real_addr, flags=0x0, protocol=0
        src ip/id=0.0.0.0, mask=0.0.0.0, port=0, tag=0
        dst ip/id=0.0.0.0, mask=0.0.0.0, port=0, tag=0 dscp=0x0
        input_ifc=outside, output_ifc=any
When I did the packet-tracer both ICMP and http it just drop on Phase 4..as bellow, I just want to know what this ACL and where its been applied to..?
What is the correct syntax for packet-tracer command when troubleshooting AnyConnect VPN to check access inside/dmz server..?
I have used as follows:
packet-tracer input outside icmp 172.16.1.1 0 8 192.168.200.63 details
Appreciate if someone can help me out on this..
thanks

To start with it is not ideal to configure a port based split tunnel. It is not support and will give you weird results like one you are experiencing. You should use standard access-list for the split tunnel and to restrict the users to the following port use vpn filter.
As far as packet tracer is concerned for the VPN client if you use the outside interface as source it will never work the reason is the connection between the ASA and the client is of real IP address (Public) and the traffic that you are testing with is a VPN encrypted traffic your ASA's outside interface doesn't know what is 172.16.1.1, he will check it against the outside access-list and will drop it.
So in your case i would strongly recommed that use standard access-list for the split tunnel and to restrict the user to specific port use vpn filter. Following are the links to configure the same:
Allow Split Tunnel for Anyconnect:

We are setting up an old office building as an offsite data center. The network cosists on a PIX 501 firewall and a 2811 router. I am attempting to setup a GRE tunnel over IPsec back to the main office. The main office consists of a PIX515, a 2821 router, and a 2921 router.
There is also an ASA5510 in our main office that is used as our primary connection for all of our external services and as a GRE endpoint for our other offices. The PIX515 is used to connect our main office clients to the internet and we would like traffic between it and our offsite data center to go across it as well.   The default route is to use the ASA.   We used policy based routing on the 2821 and 2921 routers to direct the appropriate traffic to the PIX515.
I have attached a PDF that shows a general overview.
Right now I am not able to get the tunnel setup. It appears that the offsite datacenter is sending packets but is not receiving any when I issue the “show crypto ipsec sa” commands on both firewalls. I will show the output of that command below.

I'm not sure where the issue lies and have beat my head on this for awhile so any help/insight is greatly appreciated. If there is anything else you'd like to see please let me know.

Hi Joe,
This should be moved to a VPN forum, however, something comes up Really quickly from the problem. Here:
   #pkts encaps: 0, #pkts encrypt: 0, #pkts digest: 0
Thats from the Pix on the Main office, so I think the GRE traffic is not either getting or being encrypted. I am assuming this is the IP address of the router behind the main office 10.254.10.6 is that correct?
If so, I would put a capture on the Pix to see if the GRE traffic is getting to that PIX on the inside (Unencrupted but Encapsulated on GRE) and make sure that it is not being dropped. To ensure that, you can see the logs on the PIX and see if the firewall is dropping the GRE previous being encrypted.
Also, a packet tracer can be run to ensure that the Traffic has a VPN phase which would indicate that it is following the correct phases and it would be encrypted.
Let me know.
Mike Rojas.

VPN and QOS

Hi,
Just installed a WRT610N and am connecting my Cisco Softphone through the VPN. Can I still set up QOS priorities? Since it is a softphone, does it have a MAC address or is that the MAC for my laptop running the phone?
Thanks!
Paul

As an edit to my previous post, I've done some more searches and come up with additional details.
From what I've been able to tell, establishing QOS rules for a softphone is not as simple as choosing a port. Instead I've read about things like GQoS, DSCP, and TOS. At the moment I have no idea if my current softphone (vbuzzer) supports any of these things, but I've installed X-Lite 3.0 which does support QOS packet tagging. So, then, which of these does the WRT610N recognize? How should I configure its QOS settings in combination with the X-Lite settings?
For what it's worth the X-Lite 3.0 manual does a good job of describing its support of these features; see page 40. Also helpful was this post.
Thanks very much for any assistance you can offer.

IP Phone SSL VPN and Split tunneling

Hi Team,
I went throught the following document which is very useful:
https://supportforums.cisco.com/docs/DOC-9124
The only things i'm not sure about split-tunneling point:
Group-policy must not be configured with split tunnel or split exclude. Only tunnel all is the supported tunneling policy
I could see many implementation when they used split-tunneling, like one of my customer:
group-policy GroupPolicy1 internal
group-policy GroupPolicy1 attributes
banner value This system is only for Authorized users.
dns-server value 10.64.10.13 10.64.10.14
vpn-tunnel-protocol ssl-client
split-tunnel-policy tunnelspecified
split-tunnel-network-list value split-tunnel
default-domain value prod.mobily.lan
address-pools value SSLClientPool
webvpn
anyconnect keep-installer installed
anyconnect ssl rekey time 30
anyconnect ssl rekey method ssl
anyconnect ask none default anyconnect
username manager-max password XTEsn4mfYvPwC5af encrypted privilege 15
username manager-max attributes
vpn-group-policy GroupPolicy1
tunnel-group PhoneVPN type remote-access
tunnel-group PhoneVPN general-attributes
address-pool SSLClientPool
authentication-server-group AD
default-group-policy GroupPolicy1
tunnel-group PhoneVPN webvpn-attributes
group-url https://84.23.107.10 enable
ip local pool SSLClientPool 10.200.18.1-10.200.18.254 mask 255.255.254.0
access-list split-tunnel remark split-tunnel network list
access-list split-tunnel standard permit 10.0.0.0 255.0.0.0
It is working for them w/o any issue.
My question would be
- is the limitation about split-tunneling still valid? If yes, why it is not recommended?
Thanks!
Eva

Hi,
If you're not using certificates in client authentication then the SSL handshake will complete before the user is requested to authenticate with username/password. If this authentication request fails you will see the SSL session terminated immediately following this failure (as in the logs you provided). Notice the 5 seconds between the SSL session establishment and termination, this is most likely when the user is being authenticated against the aaa server. If the phone is failing authentication against an external aaa-server you'll want to investigate the logs on that server to determine the root cause of the failure. The ASA can also provide confirmation of the authentication request/reject with the command 'show aaa-server'. If you want to see what's going on at an authentication protocol level you can enable several debugs including "debug aaa authentication|common|internal' and protocol specific debugs such as 'debug radius user|session|all' or 'debug ldap'.

Can you create a Remote Access VPN connection to tunnel DMZ LAN and Inside Networks simultaneously?

I have a customer that has a ASA 5510 version 8.3 with IPSEC Client Access that includes some of their networks on the Inside interface. The issue they are having is when their mobile users connect with the vpn client (which is using split tunneling), they can no longer access their web server applications that are running in the DMZ. Without the client connected, they access the web servers via the external public IP. Once they are connected via vpn, their default dns server becomes the internal AD DNS server, which resolves the DNS of the web servers to the private DMZ ip address.
Can a Remote Access VPN client connection be allowed to connect to both the DMZ interface and the Inside Interface? I had always only setup RA VPN clients to connect to networks on the Inside Interface.
I tried adding the DMZ network to the Split Tunnel list, but I could not access anything it while connected to vpn using the private IP addresses.

Yes, you should be able to access DMZ subnets as well if they are added to the split tunnel ACL. You could check the NAT exemption configuration for the DMZ and also check if the ASA is forwarding the packet through DMZ interface by configuring captures on the DMZ interface.
Share the configuration if you want help with the NAT exemption part.

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,
Razi

Did you figure this out?
