Cisco VPN :: ASA5520 Client-less SSL VPN With Smart-Tunnel
Sep 12, 2012
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`ve setup smart tunnel with different applications. (mstsc.exe, putty.exe). This works fine. I`ve now tried to add the vSphere client appliaction (VpxClient.exe). But i don`t get it working.

Our firewall expert has gone off on long term illness leave and I am trying to pick up the pieces :-(
We have an ASA 5520 (local office) talking to another ASA (remote office) via a VPN Tunnel.
My 1st problem is that I cannot ping from my inside network (local) to the outside interface of my remote ASA.
My 2nd is that I have debug enabled on my rules but am not logging anything.

I have asa 5505 configured with smart tunnel for mstsc.exe only. It work fine only if I use IP address of Terminal Server(192.168.1.1 for example) in Terminal Client(mstsc). But it does not not work if I try to use fqdn of Terminal Server (servername.domain.name for example). Is it possible to use mstsc.exe with smart tunnel with FQDN of Terminal Server?

Two part question: First is there a way to create a smart tunnel link on a user's home page like you have on the main portal page of the ASA 5550? I see the code that it is using but have not been able to get this to work. Here is that code;
<a href="javascript: parent.doURL('756767633A2F2F70676B636562712E7070757A702E6265742F50766765766B2F4B72614E63632F6E6867752F79627476612E6E66636B',[{name : 'user', value : 'CSCO_WEBVPN_USERNAME'},{name : 'password', value :
[Code]....
Second question when will MACs be able to auto start smart tunnel when the user first logs into WebVPN? Right now the only way I know of starting a smart tunnel on a MAC is a link on the main portal page. I am running code 8.3.2.13

I was recently tasked with adding a redundant internet connection for one of our remote sites. this new connection was to be used as the primary connection for the VPN from the site with the existing one being configured as a failover controlled by an IP SLA tracker on the new interface.
The existing connection uses a PPPoE connection configured under Dialer1 associated with FE0 to connect to our ASA. Duplicating this wasn't an option given the hardware that the second ISP provided. They provided a /29 for use; I configured FE2 using a Vlan interface with a host on that subnet.
I duplicated the connection profiles and tunnel groups on our ASA, changing only the Peer IP. Both interfaces on the 1811 are using the same crypto map.
The new connection seems fine and I can reach other hosts on its subnet from both the router and hosts on the inside of the NAT.
The issue happens when I change the default route to use the new connection.
I'm able to reach internet hosts using the new connection and I can see the VPN being established on the ASA while the VPN from the old connection drops, but I can't get traffic to route over the tunnel.
If I remove the default route that uses the new connection the VPN comes back up on the old connection just fine. There's no problem routing over the VPN when it uses that connection, just the new one.
Relevant config from show run:

We have an ASA5520 version 8.3(1) We have an existing VPN tunnel between us and our partner site. We need to add a new vlan to our existing VPN tunnel.
Where do we need to add the new vlan to in ASDM interface? Looking through using ASDM, I found 3 places.
Site-to-Site VPN:
1) Connection profiles
2) Advanced > crypto maps
3) ACL Manager

We have ASA 5520 running 8.2(3) software and we're trying to make Remote Access VPN (l2tp/ipsec) working from Android. We succeeded in making IPSEC tunnel (ending "Phase 2 completed"), but we cannot make L2TP tunnel working.We're using RADIUS for L2TP authentication, but ASA doesn't even try to check credentials entered by use. The same set of credentials entered on Windows {XP, VISTA, 7, Mobile} works ok. Which debugging options should we turned on?

My remote VPN device (static IP address) is setup to connect on the ASA5520 DMZ interface.
Peers performing L2L IPsec VPN with pre-shared keys sync-up regardless of which identity mode selected. If I set the router to “crypto isakmp identity address” or “crypto isakmp identity hostname” the ASA still accepts the connection. Also tunnel mode on initiator (router) is set to “TRANSPORT” but negotiates to TUNNEL mode with ASA.
I am able to successfully ping and telnet from a remote device through the router -- ASA5520 VPN tunnel into the HQ hosts so I can see communication is working.Initial ISAKMP negotiation debugs on router (below) shows the differences but the ASA accepts anyway.
-ASA5520 8.0(4) running in router mode
-ASA should only answer, never initiate VPN sessions
-Cisco 2800 router IOS 12.4 Adv Security should always initiate the VPN session.
-Cisco 2800 router does not have option of key-id, only address, hostname and dn.

A lot of times our users will have a bad connection from where they are connecting in from. Their Internet connection will drop and the VPN Client disconnects but on our Cisco ASA5520, the connection will still be connected and when their Internet connections comes back, they are not able to connect as the session is still up on the 5520. Is there a way to make the connection clear quicker? I have IKE Keepalives on the RA Profile (Confidence 300 seconds, Retry Interval 2 seconds) but it seems to keep the session longer than that. Is there anything I can do to make the connection clear quicker?

I am using an ASA 5520 running 8.2(4). My objective is to get a VPN client to access more than one network on the inside of the network, i.e., I need to VPN in with an IPSec client and be able to establish tcp connections to servers at 192.168.210.x and 10.21.9.x and 10.21.3.x, I believe I am close to having this resolved, but seem to have a routing issue.

I have a Cisco ASA5520 that I have setup to allow a GRE tunnel through from a router at site B. This all works fine when I use the below NAT with associated router object on the inside
object network SWTEST nat (inside,outside) static interface
My problem comes in that this kills off my Cleintless VPN connection to the same firewall, I changed my NAT to point at another of my statically assigned IP addresses, and then nothing works. Can anyone help with what I've done wrong, or what i should do? My rule base allows any GRE in from the source, and rules all look fine.

Cant seem to get around this one yet. I have a remote ASA that I can VPN into. It has 2 dmz's, outside and inside interface configured.
Inside subnet is 192.168.11.0 / 24
DMZ2 is 192.168.13.0 / 24
VPN client pool is 192.168.15.0 /24
I login in fine. But have no access to the DMZ2 subnet. I get the failure listed above.

How can I NAT the same set of four hosts and give them access to two different networks across an IPSEC site-to-site VPN tunnel? I'm using an ASA5520 running 8.04.
I have four hosts say: 10.240.1.1-10.240.1.4
They need access to two different networks:
205.100.150.0
140.175.200.0
I woud like to NAT them as something like:
7.5.210.1
7.5.210.2
7.5.210.3
7.5.210.4

I have a site-site VPN tunnel between my location and my remote office. My remote office is changing their ISP, so the VPN GW is getting changed. do i need to create new site-site tunnel again or changing the remote peer VPN GW in my FW is enough? FYI, i have cisco ASA5520 and my remote office has check point UTM-1 edge box.

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.

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.

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.

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 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:
-access-list split permit ip host 10.1.1.12 172.16.4.0 255.255.255.0
-access-list split permit udp host 10.1.1.9 eq 53 172.16.4.0 255.255.255.0
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.

how to setup a both ends of an IPSEC VPN tunnel using a software client such as shrewsoft vpn and an 800 series router?
I've tried following the instructions on cisco's site, but I don't really understand which interface I should use? Dialer, VLAN1 or UnNumbered to a Loopback?
I'm OK with most basic features of the router, but never had any luck with VPNs?

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.

inside network----ASA5505========internet===========Remote VPN client.
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.
