VPN OK on 1812 - not on 2811!
Hello
I'm losing my mind... I configured a remote access of the IPSec VPN client on 2 routers 1812. It works like charm.
I take the same configuration and apply it on a 2811, it does not work... Error during phase 2 of IPsec.
I re-re-re-re-double checked the config, it perfectly matches the config on the 1812. (and I use the same model for 876, 1841,...)
I tried 4 different IOS 12.2.24T3 Adventerprise, 12.2.15T13 adventerprise and Advipservices and 12.2.25c adventerprise. Nothing changes... still the same error...
I apply this config on an another 2811, the same question. Is there something wrong with this model for IPsec VPN client config? Or should I use a specific IOS?
Thanks for sharing your experience,
Kind regards
Olivier

Oliver,
Should work as you said.
What is the error you're getting about the phase 2?

Original title: unable to connect to the internet
Whenever I connect to my computer and get it on my desk, it goes on to say that Cisco AnyConnect VPN Service not available. How can I fix? I am not connected to the internet and I can't connect to the internet as well. He said also Cisco AnyConnect VPN service agent is not an answer. Please restart this application after a minute. Also, I can't use my firewall for some reason, if I try to allow its loading and the greenbar's going that far - then stops and says that there is an error. I forgot where I tried to activate.
Oh thanks for the help but I fix it myself. I just did a system restore to a month before

Hello
I looked at the configuration of your router RT-897VA once again, and I don't know if static NAT statements in there are supposed to work or not, but they won't because you have not specified any inside and outside interfaces. Configuration changes below correspond to the configuration of your router RT, check if their implementation makes a difference (the changes are indicated in bold):

I appreciate any help or advice on your part.

First of all your cryptographic domains do not match, correct so that the first. They are the same on both sides.
That's what they say.

VPN access to the not directly connected networks
Hello
I have a 5510 which is used for Client VPN access and there is something simple that I can't work.
The VPN part works very well with AAA on a CBS.
But what does not is access to networks that are not directly connected to the inside interface.
That is to say the VPN users can connect to the network within the Interface (say 192.168.0.0/24) but not a 10.0.0.0/8 network which is connected through 192.168.0.1 router.
I have the static routes in Routing and firewall all showing the way back to the firewall on all the other networks, but I don't get more far the 192.168.0.1 router...
I use split tunneling and pass all of the private over the VPN - internet networks is used through the own local access to clients.
Can someone help me out here?
Thank you.
Fraser
PS: have the same type of access on a 7206VXR and soft, everything can be consulted and which is necessary - but I would like to move this service to the ASA.
Fraser
I don't understand the ASDM parts as you suggest. The code would be great.
I would also recommend control ACL applied to the inside interface (if any) that it allows traffic as
inside_access_in list of permitted access 10.0.0.0 255.0.0.0 vpnsubnet vpnnetmask
If still no joy, attach your config sanitized, would be useful for me to diagnose.

PIX of VPN to Pix does not allow navigation from one end.
Hello
We went an office of a router to connect to the internet (do Nat) our Pix VNP company. Now from this office, I can go through all our corporate network, but I can't browse them from our corporate network. I read a few cisco docs and I installed WINS, still no luck.
Technicians from the isp for this office recommended disable Nat on this router (its doubly from). I have to change this Office Ip address external PIX and the default gateway to match any Ip subnet, they give me.
This change will affect our current VPN IKE and IPSEC policies and connection to that office?
Thank you
Mario Cabrejo
Network engineer
You will need to use an external (visible ip internet) on the external interface of the PIX and disable the NAT on the router. You have to re-create the tunnels they will point to a new ip address and not the router.
Hope this helps

AnyConnect VPN full tunnel could not access the site to site VPN
I have a set of AnyConnect VPN upward with no split tunneling (U-turning/crossed traffic), running 8.2.5 code.
It works fine, but I want to allow customers to AnyConnect VPN site to site, which I was unable to access.
I checked the IP addresses of network anyconnect are part of the tunnel on both sides.
My logic tells me that I must not turn back traffic from the network anyconnect for the site to site VPN, but I don't know how to do this.
Any help would be appreciated.
Here are the relevant parts of my config:
(Domestic network is 192.168.0.0/24,
the AnyConnect network is 192.168.10.0/24,

How to set up VPN on the router via ASA5505 2811
Hello everyone
I apologize for the possible triviality of my question. The current configuration of our society considers appropriate for the edge, two ASA5505 below that are installed two routers configured with the CCME 2811 Express. When the two AS5505 is configured a VPN connection for the transmission of data in our network traffic. Given the presence of several public addresses available on our two sites, I was wondering if you could (and if so, how) to set up a VPN between two routers 2811, except that when existing data traffic, dedicated exclusively to the voice traffic. It give me a document that teach me how can I solve my problem?
Thank you very much
Damiano,
If you want an IPsec VPN for only separate voice and termination traffic on routers, there are several possibilities. Especially if you have a spare IP addresses:
IPsec VPN endpoints on the routers.
GRE over IPsec routers ending (gives you that soften what and where can be routed, in particular, identify voice traffic)
Termination of free WILL on the routers and unloading IPsec to ASAs. (Benefit of the foregoing + ASAs making encryption).
There is no problem to close the tunnels through the ASA, the only warning is that even in the case of static NAT you should probably use NAT-Traversal.

VPN works locally but not remotely
I our ASA 5510 put in place to create a vpn for our users. When I test locally it works fine, but when I try to use it remotely, it will not work. In addition, port 500 is open locally but not remotely. What Miss me? I was told that there is no firewall in place that would affect me.
Dan
You say port 500 (UDP) is not open remotely.
How do you as a customer to connect if UDP 500 is not open on the client side?

VPN Site to Site not upward Tunel on a router
Hello
First time I try to configure the VPN Site to Site on the two routers X and Y. I use cisco SDM
X router that I have set up on this path http://www.tekkom.dk/mediawiki/images/e/ee/IP_sec_site-to-site_sdm.pdf
Then I create a mirror and spent on router Y I tunel up VPN router Y.
But I have problem with router X. When I try to the top of Tunel, I have two problems:
The peer must be routed through the crypto map interface. The following host is routed through the non-crypto map interface. (1) 79.*. * **. **
(79.* *-it is the WLAN router address Y)
Destination of traffic of the tunnel must be channelled through the crypto map interface. The destination following (s) is routed through non-crypto map interface. (1) 10.*. * **. **
(10.* *. *-is router LAN address Y)
Configuration of routers in the files.
Apologies for the lack of your answer.
You have the same card encryption applied to the physical interface and dialer0 interface. You can try removing it from the dialer0 interface and a new test.
If it does not can try you backwards IE. remove physical and apply to the dialer0 only.

Return VPN traffic flows do not on the tunnel
Hello.
I tried to find something on the internet for this problem, but am fails miserably. I guess I don't really understand how the cisco decides on the road.
In any case, I have a Cisco 837 which I use for internet access and to which I would like to be able to complete a VPN on. When I vpn (using vpnc in a Solaris box as it happens which is connected to the cisco ethernet interface), I can establish a VPN and when I ping a host on the inside, I see this package ping happen, however, the return package, the cisco 837 is trying to send via the public internet facing interface Dialer1 without encryption. I can't work for the life of me why.
(Also note: I can also establish a tunnel to the public internet, but again, I don't can not all traffic through the tunnel.) I guess I'm having the same problem, IE back of packages are not going where it should be, but I do know that for some, on the host being ping well, I can see the ping arriving packets and the host responds with a response to ICMP echo).

Hi Eric,.
(Sorry for the late reply - needed some holidays)
So I see that you have a few steps away now. I think that there are 2 things we can try:
1)
I guess you have provided that:
IP nat inside source overload map route SDM_RMAP_1 interface Dialer1
Since the routemap refers to ACL 100 to define the traffic to be translated, we can exclude traffic that initiates the router:
Access-list 100 category SDM_ACL = 2 Note
access-list 100 deny ip 123.12.12.185 host everything
access-list 100 deny ip any 10.10.148.0 0.0.0.255
access ip-list 100 permit a wholeWhich should prevent the source udp 4500 to 1029 changing port
OR
2)
If you prefer to use a different ip address for VPN,
Then, you can use a loop like this:
loopback interface 0
123.12.12.187 the IP 255.255.255.255
No tap
map SDM_CMAP_1 crypto local-address loopback 0
I don't think you should apply card encryption to the loopback interface, but it's been a while since I have configured something like that, so if you have problems first try and if still does not get the crypto debugs new (isakmp + ipsec on the vpn, nat router on the router of the client package).

Authentication of VPN 3000 Client does not
Get the following error trying to authenticate on VPN 3020: Xauth required but winning proposal does not support xauth, of audit priorities of the xauth list proposal ike ike proposals
Not really sure what it means.
Find the proposals on the VPN3020 IKE (location varies depending on the version, so I can't tell you where). You will find some are active, others do not. Make sure that one is active when the authentication method is "pre-shared keys (xuauth)" with something like MD5, 3DES, DH group2.
If you see a proposal named "CiscoVPNClient-3DES-MD5" that will do the trick.

Help: Customer Cisco VPN &; Split Tunnel but not Internet
Hi Forum.
We are faced with this problem: after having successfully open a VPN connection with the Cisco VPN Client to a router Cisco, the rest of the world are not properly available more.
This is what has been verified / so far attempted to identify the problem on a Windows Vista computer:
-Router: Split Tunneling is allowed according to sysop
-On the VPN-Client: "allow Local Lan access" is checked
-On the Client (statistics): only STI VPN-rout configured listed unter "guarantee routes." "Local Lan routes" is empty.
-Calling 'http://www.google.com' in IE fails
-Call ' 74.125.232.116' (IE IP) IE works / ping the IP works.
-nslookup properly lists the current DNS server
-nslookup www.google.com resolves correctly the name of intellectual property
It seems that it is not that the connection with the rest of the Internet is deleted, but DNS resolution fails somehow, even though all signs point to the appropriate DNS server is in force and although the command line can resolve the name.
does anyone have a tip how to debug this correctly?
No worries Pat...
