Cisco :: Can't Get Any Client To Establish DTLS Tunnel When Connecting
Nov 25, 2012
I've been labbing on my asa5505 at home, setting up different VPN solutions for testing purposes. However, I can't get my anyconnect client to establish a DTLS tunnel when connecting (anyconnect only shows tls, and does not display any errors about not connecting with dtls)I have set dtls port to 444 and this port is open on the other side.
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.
Can I configure a PIX (515), as PPTP client to establish a tunnel with non-Cisco PPTP server ? Can my PIX initiate this type of connection ?Today, I use a PC with PPTP client to establish this and I want replace this with a PIX and I don´t want depends of a PC.
I´m getting a dynamic public IP from my provider and what I´m trying to do is to establish a remote vpn tunnnel using IPSec which I achieve but every time the sessions resets or the ASA 5505 resets I get a new public IP and I need to put the new IP on the remote client so I can establish the vpn... How can I establish an ipsec vpn using DNS? For this scenario the remote vpn client is a vpn phone but it could be for any vpn client.
Private IP Public IP Private IP PBX ---- (LAN) ---- ASA 5505 ---( Internet ) --- Remote Site ( Router ) --- (LAN) -- VPN Phone
I have a client that needs to establish a IPsec tunnel to a large organization. They will not forward any traffic to an IP using private reserved IPs. However I am not finding another way to accomplish this. I tried ipsec to the router and using a second IP to a 1:1 Nat but it will not pass the traffic and would seem really insecure from the public internet. 1:1 Nat does work from the public internet but not over the tunnel.I have an RV042 a /29 block of IPs. I am at a loss of how I can accomplish what they want without allowing a private IP.
i'm triyng to establish a vpn ipsec tunnel between my cisco2801 and a cyberoam equipment, at the end point.Debugging isakmp, i have this output, where xxx.xxx.xxx.xxx is the remote peer address, and yyy.yyy.yyy.yyy is mine.What can i try?

Iphone 4S latest IOS5 V 5.1.1 installed?I'm not able to make native IPSEC VPN connection to work against my company Cisco 877 Instead, all my notebook and netbook with Cisco VPN Client installed work fine when they remotely connect to company's 877 Enabling 877 debug, it seems Iphone successfully pass the phase 1 ike connection (in fact Iphone asks me for phase2 user/pass) but it hung at phase2 giving me back the error "Negotiation with VPN server failed"
Here is how I configured my 877 VPN part :
R1(config)# aaa new-model R1(config)# aaa authentication login default local R1(config)# aaa authentication login vpn_xauth_ml_1 local R1(config)# aaa authentication login sslvpn local R1(config)# aaa authorization network vpn_group_ml_1 local R1(config)# aaa session-id common
It seems 877 even comes to allocate a local LAN ip address to Iphone (192.168.0.21) but then something goes wrong.....
Device asa 5550 - But can a Client establish a SSL VPN to remote network and devices on the remote network access local network printers? so you got one client one network A that creates a SSL VPN to network B , can network B be configured so that automatic job come across the same ssl vpn to a Different IP?
Does RV082 can establish PPTP VPN connection as CLIENT? (i'm aware it can provide function of VPN PPTP server but could not find if it can act as client).To explain further: I'm based in Europe and use US VPN to access some US services like Netflix, Pandora, etc.. (i'm paying for US VPN account as service so I have no other choice than PPTP). I would like to establish permanent PPTP VPN tunnel with remote server so all computers in the house can go through tunnel when i browse for Pandora or Netflix for example (is this router capable of routing policy too so not all the traffic would be routed through tunnel?)
As you can see i have problems with connecting 2 SRP521W together for an VPN tunnel. I tried as much as I can but now i dont know what to do or how and where is the mistake? the connection between these two devices was there last week, after weekend (nothing changed in configs) the connection suddenly was interrupted, without any reason or warning. another day it worked again and 20 mins later connection was dead again...and now it wont establish at all.. here are some screenshots from the vpnconfigs of my devices. one has a static IP the otherone uses FQDN. These are the IKE policies: Here the IPsec Policies: and the GRE policies:
We have configured a site to site tunnel from our ASA to another organizations Cisco 3030. It appears to have just one way initiation. We can do a ping to a device on the remote site and it will ping just fine. however, when the tunnel needs to be initiated from the remote site, it will not work until we have initiated the tunnel and then everything works.
I continue to see Error processing payload: Payload ID: 1 errors on the ASDM logs.It appears that all the configuration is in place because we can in fact establish the IPSec tunnel unidirectional. And once established, traffic can flow bidirectional.
Last week, I was able to establish a site-to-site VPN tunnel between an ASA 5505 and Cisco C881 router just fine. The tunnel was up and and running for a number of days but today the tunnel is no longer up. I was wondering how, if there are any commands to re-establish or re-initiate the tunnel.
I have implemented a Clientless SSL VPN solution with Smart-Tunnel feature on Cisco ASA 5520, software 8.4(4)1.I have been successful in making Bookmarks which employ Smart-Tunnel feature to avoid content rewritting (if any). And in reality it works fine with some links. However there are some links to an Oracle portal, it doesn't work.I was able to log into the Oracle portal with its username/password. However when i click into a button of the drop-down menu, nothing happens while normally there should be a box appearing. The Oracle portal runs with some Java stuffs which i don't really know as i am not a programming engineer anyway.
I would like to know whether I will be able to setup a VPN tunnel between a wireless router and wireless client on the same network. What I plan to do is to first setup up my router to use DD-Wrt as its OS. I have read some tutorials on the Internet, about how one can configure a VPN server when using this router OS.Now if I assume that I have a client on the same WLAN network who is already connected and so on; - can the client connect to the router's VPN server and then connect to the Internet using the VPN tunnel that has been established? The purpose of this configuration is to see whether if this setup (if it can actually be configured that way) would protect against wireless man in the middle attacks that use trivial tools such as Cain and Abel.
we use the Cisco VPN-Client to connect to our CISCO1921 Router and want to go out again on the same interface to the internet. We configured the connection with the IOS scurity package, have no split tunneling - so the client is forced with it's default gateway to our router - we also have pushed our local dns-server to the client and he gets dns results. Now I think we have to got out with some kind of NAT, because our client has a private IP from the IPSec Client pool. At the moment we have no NAT inside/outside, bacause we only use official IP addres in- and ouside (data-room usage).
- Is it possible to get the NAT function going in and out on the same interface with crypto_map IPSec user comming in and going out to the internet ? - Is it more secure to configure this with vrf ? - Has some a link to example configurations for this ?
I can connect to the router over VPN just fine, problem is that once I connect I can not access the 192.168.1.0 network... can't ping a workstation on the network 192.168.1.25, I can however Ping the Router which is 192.168.1.254.
FastEthernet 4 is my WAN
used this for setup: [URL]

I have a customer I've built a webvpn tunnel for.Users on this tunnel need to have http access to a server at 10.1.1.12 and nothing else.That's fine, but in order for name resolution to work properly they need to be able to send DNS requests to 10.1.1.9.I'm working with two different access lists, my non access list (nat 0) and my split tunnel access list. I can't specify ports in the nat 0 access list, but I did try writing my split tunnel access list as follows:
When I do that users can access the 10.1.1.9 dns server, but they can hit it on anything (ping, 3389, etc.).I'm trying to figure out how I can limit them so they will only be able to pull dns but nothing else.They have the Any connect Essentials license, so unfortunately a clientless VPN is not an option. Is there some other access list I can interpose that will limit things the way I want?
I am using a RV110W as a VPN client to establish a VPN conection since some months. So far everything works fine. But all traffic is routet thru the VPN tunnel. Now I try only to route specific adresses thru the tunnel but not the internet acess.
RV110W is in Gateway mode WAN interface is connected with internet I am using PPTP with PAP and MPPE for VPN so far no static routes (I could not set e.g. a route to 0.0.0.0 because web-interface says its not a valid adress)
Goal is to route only traffic for the target network thru tunnel and the rest direct via WAN interface.
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 recently purchased a Cisco 2911 to replace my Cisco 1711 router. I copied the configuration from the Cisco 1711 router to the Cisco 2911 router. Everything seemed to work correctly except when I VPN tunnel into the Cisco 2911 router using Cisco's VPN client version 5.0. I can ping the router LAN interface from my PC that is VPNed into the router but I can no longer ping or access the devices on the LAN side of the router as I did on the Cisco 1711 router. I don’t see errors in the log or hits blocking anything in the acls. It’s using the same configuration that I had on the Cisco 1711 router, and this did work on the Cisco 1711. The Cisco 2911 router is running IOS Software, C2900 Software (C2900-UNIVERSALK9-M), Version 15.0(1)M1, RELEASE SOFTWARE (fc1).
Here is the VPN clinet portion of the configuration: The LAN is addressed as 192.168.0.0/24. The router LAN interface is 192.168.0.1, which I can ping and access. I can't ping or access anything on the LAN (192.168.0.0/24) beside the router.

The ASA has one public IP on its outside interface and using PAT to the internet. It only has two interfaces, inside and outside using vlan. I created a IPSec VPN through CLI. My goal is for the remote client to browse the Internet throught tunnel.
Q1: Is it possible?
Q2: The remote side gets connected and has IP from the pool, with is part of inside network. But it cannot ping anything, including the gateway, which is the inside interface. I debug it, it shows the ASA receives the ping packages, but it doesnt send anything back to the client.
I have configured a lab for RA VPNs with a ASA5510 software version 8.2 and VPN Client 5 using digital certificates with Microsoft CA on a Windows 2003 server. I did the configuration based on this document from Cisco website: URL
Now the vpn works just fine, but now I need to configure different tunnel-groups so I can provide different services to different users. The problem I have now is that I don't know how to configure it so the certificate matches the tunnel-group name. If i do a debug crypto isakmp on ASA I get this error messages:
%ASA-7-713906: IP = 188.8.131.52, Trying to find group via OU...%ASA-3-713020: IP = 184.108.40.206, No Group found by matching OU(s) from ID payload: Unknown%ASA-7-713906: IP = 220.127.116.11, Trying to find group via IKE ID...%ASA-3-713020: IP = 18.104.22.168, No Group found by matching OU(s) from ID payload: Unknown%ASA-7-713906: IP = 22.214.171.124, Trying to find group via IP ADDR...%ASA-7-713906: IP = 126.96.36.199, Trying to find group via default group...%ASA-7-713906: IP = 188.8.131.52, Connection landed on tunnel_group DefaultRAGroup
So basically when using certificates I always connect the RA VPN only with the default group DefaultRAGroup. Do I need to use a different web enrollment template for certificate request instead of the user template??? How can I define the OU on the User certificate so it matches the tunnel-group???
I have just upgraded one of our 4400 to 184.108.40.206. Most of the AP re-registered with out issues. I have two AIR-LAP1142N-E-K9 on a remote site that will not re-register.I have pointed them to another 2125 WLC (220.127.116.11) and they register fine. Point them to yet another 4400 (18.104.22.168) I get the same issue.I am getting this error when the register on the 4400s.*Jan 11 14:39:24.000: %CAPWAP-3-ERRORLOG: Selected MWAR 'abzewwlc'(index 1).*Jan 11 14:39:24.000: %CAPWAP-3-ERRORLOG: Go join a capwap controller *Jan 11 07:05:55.000: %CAPWAP-5-DTLSREQSEND: DTLS connection request sent peer_ip: 22.214.171.124 peer_port: 5246*Jan 11 07:06:55.000: %DTLS-5-SEND_ALERT: Send FATAL : Close notify Alert to 126.96.36.199:5246 I suspect it may be as they both have In the client config.Then again maybe not.Configured Switch 1 Addr 188.8.131.52Configured Switch 2 Addr 184.108.40.206
Question 1 if I do a "clear config except static IP" will I still be able to telnet tp them or will they default to no telnet no ssh ?
Question 2 any idea how to get past this DTLS error ?
I have an ASA 5510 running 8.2.2 code with 30 VPN Phones connected. Of the 30 phones, I have 5 that do not negotiate DTLS and I'm having quality issues with these phones. I've checked the login process and I don't see any errors when these phone connect, they just don't even attempt DTLS. All the phones use the same VPN configuration.
My work laptop uses a Cisco AnyConnect VPN Client (Software Version 2.5.2006). The connection protocol is DTLS.I recently upgraded to a Cisco RV180 at home at it is running the latest software version (220.127.116.11).
Since the RV180 went into service the work laptop will connect intermittantly. Usually email works but web browsing and and other services do not. It is slight strange behaviour- and seems to defy what a VPN should do......
The behaviour is very repeatable. For example from the customers office the laptop connects perfectly via VPN and if I swap back to an older inferior make of router at home VPN also works normal without changes to the laptop configuration.
I work for a large company (70,000+ employees) and we use "standard" builds so altering the laptop configuration is not really an option.
It seems to me that the RV180 doesn't support the DLTS VPN connection (indeed DLTS passthrough isn't an option in the VPN passthrough list) and is possibly blocking some incoming packets on the WAN interface.
I haven't yet tried a firewall rule to allow a DLTS (or UDP perhaps?) connection back in from the WAN side (obviously from just the IPs at my work end) but this is the only option I can think of to make this machine connect "correctly".
Our internet connection changed and so did our public IP addresses, I'm trying to re-establish our VPN tunnel with our client, but we haven't be able to get the connection back up even though only 2 IP addresses have changed. Below is my ASA 5510 config file Our WAN from the ISP is: 65.xx.xxx.104/30 and our LAN is: 67.xxx.xxx.128/27, I'm trying to use: 65.xx.xxx.106 as the endpoint and 67.xxx.xxx.130 as the host via the tunnel.
How can I configure an ASA 5505 NEM client to allow access to the Internet when the tunnel to the headend is down? I am planning on deploying back to back ASA 5505s in network extension mode but I do not want to block Internet access on the client side if the tunnel to the server should go down.
i've configured Cisco VPN CLient on a router 2821, and it is working fine.I could access inside resourses normally>the problem is that when i connect with VPN i lost connectivity to internet? What is wrong with my configuration? Below the running config of the router.
