Clientless SSL VPN and ActiveX question
Hey All,
First post for me here, so be gentle. I'll try to be as detailed as possible.
With the vast majority of my customers, I am able to configure an IPSEC L2L VPN, and narrow the traffic down to a very minimal set of ports. However, I have a customer that does not want to allow a L2L VPN tunnel between their remote site, and their NOC center. I thought this might be a good opportunity to get a clientless (they don't want to have to launch and log into a separate client) SSL VPN session setup. Ultimately, this will be 8 individual sites, so setting up SSL VPN's at each site would be cost prohibitive from a licensing perspective. My focus has been on using my 5510 (v8.2(5)) at my corp site as the centralized portal entrance, and creating bookmarks to each of the other respective sites, since I already have existing IPSEC VPN's via ASA5505, (same rev as the 5510 )setup with each of the sites.
First issue I've run into is that I can only access bookmarks that point to the external address for the remote web-server (the site has a static entry mapping an external address to the internal address of the web server). I am unable to browse (via bookmark) to the internal address of the remote web server. Through my browser at the office, I can access the internal address fine, just not through the SSL VPN portal. I am testing this external connectivity using a cell card to be able to simulate outside access. Is accessing the external IP address by design, or do I have something hosed?
Second issue I face is when I access the external address through the bookmark, I am ultimately able to log onto my remote website, and do normal browsing and javascript-type functions. I am not able to use controls that require my company's ActiveX controls (video, primarily). I did enable ActiveX relay, and that did allow the browser to start prompting me to install the controls as expected, but that still didn't allow the video stream through. The stream only runs at about 5 fps, so it's not an intense stream.
I have researched hairpinning for this situation, and "believe" that I have the NAT properly defined - even going as far as doing an ANY ANY, just for testing purposes to no avail. I do see a decent number of "no translates" from a show nat:
match ip inside any outside any
NAT exempt
translate_hits = 8915, untranslate_hits = 6574

192.168.17.0, and 192.168.18.0 are two other private LANS behind the remote 5505
As you can see, I have things reasonably wide open - with no port restrictions on this one yet - this is for troubleshooting purposes, and it will get restrictive as soon as I figure this out Right now, the ASA5510 is pretty restrictive, and to be brutally honest, I'm not certain I'm even using the packet tracer 100% proper to be able to simulate coming from the outside of the network through my ASA5510, out to a remote ASA5505, and to a web server behind that 5505. I'm sure that the issue is probably going to be a mix of ACL's between the 5510, and the 5505.
I guess the main question, is Clientless SSL VPN really a good choice for this, or are there other real alternatives - especially since my client doesn't want to have to install, or use an actual client (like AnyConnect), nor do they want to have an always-on IPSEC VPN. Am I going about this the right way? Anyone have any suggestions, or do I have my config royally hosed?
Thanks much for any and all ideas!
Hey All, I appreciate all of the views on this post. I would appreciate any input - even if you think it might be far-fetched. I'm grasping at straws, and am super-hesitant to tell my customer this is even remotely possible if I can't have a POC myself. Thanks, in advance!!

ASA Clientless SSL VPN can't access login pages on websites
When I'm doing a clientless SSL VPN to my ASA and using the ASA to browse websites, I can pretty much go on to just about any website except specificly login websites. I can go on google and yahoo but when I click the "mail" button it just gives me an error message "Connection Failed - Server (site name) unavailable. When I go onto hotmail.com, it says server hotmail.com unavailable. When I browse by entering hotmail's IP address in, it says "Bad Request." Same happens on ebay, youtube, etc. Funny thing is, the ONLY login page I can get onto is Cisco's website's login page. I tried changing DNS servers, nothing changed. Here is my configuration:

Can anyone please help me? ThanksIn your crypto ACLs for the site-to-site tunnels, add the ASA's public IP destined to the remote network, and mirror this ACL on the remote end VPN device.
Example:
ASA public IP: 2.2.2.2
Remote network: 192.168.1.0/24
access-list vpn_to_remote_network permit ip host 2.2.2.2 192.168.1.0 255.255.255.0
Mirror the above acl on the remote end router.

SSL VPN and dedicated IP address
Hello
I have an ASA 5505 8.3 and i setup it with ADSL 6.3
I am trying to dedicate IP addresses to clientless SSL VPN user: is it possible ?
If not is it possible with Anyconnect client ?
If yes i can't perform it !
I have a user test and i want dedicated him an IP address . After authentification user can connect to a web application but when i see the netstat, it is the IP adress of the ASA which is connected ...
Could you help me ?
Regards
L.MalandainTwo ways -
Frist create pool with one IP address and assign that to group policy.
Second- modify the user atributes-
username test password xxxxx
username test attributes

Thanks

Port forwarding for clientless SSL VPN access
Hello,
I am currently trying to set up clientless SSL VPN access for some remote sites that our company does business with. Since their machines are not owned by my company, we don't want to install/support a VPN client. Therefore, SSL is a great option.
However, I'm running into an issue. I'm trying to set up port forwarding for a few remote servers. These remote servers are different and have distinct IP addresses. They are attempting to connect with two different servers here.
But my issue is that both servers are trying to use the same TCP port. The ASDM is not letting me use two different port forwarding rules for the same TCP port. The rules can exist side-by-side, but they cannot be used at the same time.
Why? It's not trying to access the same TCP port on a server when it's already in use. Is there anyway I can get around this?
If this doesn't make sense, please let me know and I'll do my best to explain it better.Hi Caleb,
if you mean clientless webvpn port-forwarding lists, then you should be able to get your requirments. even the same port of the same server can be mapped to different ports bound to the loopback IP.
CLI:
ciscoasa(config) webvpn
ciscoasa(config-webvpn)# port-forward PF 2323 192.168.1.100 23
ciscoasa(config-webvpn)# port-forward PF 2300 192.168.1.200 23
then you apply the port-forwarder list under a group-policy
Hope this helps

Cisco ASA Site to Site IPSEC VPN and NAT question
Hi Folks,
I have a question regarding both Site to Site IPSEC VPN and NAT. Basically what I want to achieve is to do the following:
ASA2 is at HQ and ASA1 is a remote site. I have no problem setting up a static static Site to Site IPSEC VPN between sites. Hosts residing at 10.1.0.0/16 are able to communicate with hosts at 192.168.1.0/24, but what i want is to setup NAT with IPSEC VPN so that host at 10.1.0.0/16 will communicate with hosts at 192.168.1.0/24 with translated addresses
Just an example:
Host N2 (10.1.0.1/16) will communicate with host N1 192.168.1.5 with destination lets say 10.23.1.5 not 192.168.1.5 (Notice the last octet should be the same in this case .5)
The same translation for the rest of the communication (Host N2 pings host N3 destination ip 10.23.1.6 not 192.168.1.6. again last octet is the same)
It sounds a bit confusing for me but i have seen this type of setup before when I worked for managed service provider where we had connection to our clients (Site to Site Ipsec VPN with NAT, not sure how it was setup)
Basically we were communicating with client hosts over site to site VPN but their real addresses were hidden and we were using translated address as mentioned above 10.23.1.0/24 instead of (real) 192.168.1.0/24, last octet should be the same.
Appreciate if someone can shed some light on it.Hi,
Ok so were going with the older NAT configuration format
To me it seems you could do the following:
Configure the ASA1 with Static Policy NAT
access-list L2LVPN-POLICYNAT permit ip 192.168.1.0 255.255.255.0 10.1.0.0 255.255.0.0
static (inside,outside) 10.23.1.0 access-list L2LVPN-POLICYNAT
Because the above is a Static Policy NAT it means that the translation will only be done when the destination network is 10.1.0.0/16
If you for example have a basic PAT configuration for inside -> outside traffic, the above NAT configuration and the actual PAT configuration wont interfere with eachother
On ASA2 side you can normally configure NAT0 / NAT Exemption for the 10.1.0.0/16 network
access-list INSIDE-NONAT remark L2LVPN NONAT
access-list INSIDE-NONAT permit ip 10.1.0.0 255.255.0.0 10.23.1.0 255.255.255.0
nat (inside) 0 access-list INSIDE-NONAT
You will have to take into consideration that your access-list defining the L2L-VPN encrypted traffic must reflect the new NAT network
ASA1: access-list L2LVPN-ENCRYPTIONDOMAIN permit ip 10.23.1.0 255.255.255.0 10.1.0.0 255.255.0.0
ASA2: access-list L2LVPN-ENCRYPTIONDOMAIN permit ip 10.1.0.0 255.255.0.0 10.23.1.0 255.255.255.0
I could test this setup tomorrow at work but let me know if it works out.

Cisco 1841 SSL VPN and Anyconnect Help
I am pretty new to Cisco programming and am trying to get an SSL VPN set up for remote access using a web browser and using Anyconnect version 3.1.04509. If I try to connect via a web browser I get an error telling me the security certificate is not secure. If I try to connect via Anyconnect I get an error saying "Untrusted VPN Server Blocked." If I change the Anyconnect settings to allow connections to untrusted servers, I get two errors that say"Certificate does not match the server name" and "Certificate is malformed." Below is the running config in the router at this time. There is another Site-to-Site VPN tunnel that is up and working properly on this device. Any help would be greatly appreciated. Thanks

Hi Everyone,
I was testing few things at my home lab.
PC---running ssl vpn------------sw------router------------ISP--------------ASA(ssl anyconnect)
anyconnect ssl is working fine and i am also able to access internet.
I am using full tunnel
i have acl on outside interface of ASA
1
True
any
any
ip
Deny
0
Default
i know that ACL is used for traffic passing via ASA.
I need to understand the traffic flow for access to internet via ssl vpn.?
Regards
MAheshAs you say correctly, the interface-ACL is not important for that as the VPN-traffic is not inspected by that ACL. At least not by default.
You can control the traffic with a different ACL that gets applied to the group-policy with the "vpn-filter" command. And of course you need a NAT-rule that translates your traffic when flowing to the internet. That rule has to work on the interface-pair (outside,outside). -
Does the ASA or IOS support an SSL VPN that includes the Cisco softphone like it does say RDP, SSH, etc? I'm trying to determine if I can have a user connect a soft phone to our parent company's SSL VPN so they can use their Cisco phone system, while simultaneously having a remote access vpn tunnel to our division's data network. In short, our employees need to use phones that don't exist on our network while having access to our data network. I've been able to test having an SSL vpn session open at the same time as an IPSec remote access session, but the softphone is not an option in my current code of 8.4 on the ASA. I thought I heard it might be available in 9.0. It seems like it would work in reverse, i.e. having my users connect to my SSL VPN to use my data network and then IPSec to our parent company for the client's locally installed soft phone, but that's not an option for me. The link below seems to suggest it's possible in IOS at least, but I haven't been able to find any details beyond the sales pitch it offers.

SSL VPN and Dynamic DNS - ddns on IOS
Hello,
I'm trying to configure a SSL VPN tunnel via SDM on a 877 Router. The router gets the public IP address dynamically from the ISP, so I have configured the DDNS to access remotely to the router. I would like to know if it's possible to configure the SSL VPN to support the dynamic IP via SDM o CLI.
Regards
GerardSeems like i have fixed the problem using:
webvpn gateway gateway_1
ip interface Dialer0 port 443
ssl trustpoint local
inservice
However when the router is rebooted, it results in this error:
Invalid ip address First configure an IP address for the gateway
Any idea how to delay the webvpn commands at startup until dialer0 gets a dynamic IP ? -
Clientless ssl vpn homepage after login problem
Hi all,
I have a problem with my clientless vpn portal.
I need to configure that when a user logs in through the portal, something that works just fine, that he ends up on the homepage.
Right now he ends up immediatly on the anyconnect button.
With the homepage I do mean the first button that says "Home".
Users must be able to click on the "Web Applications", below "Home".
Below "Web Applications" users must have their "Anyconnect" button aswell.
First of all I wasn't able to make the portal display the "Anyconnect" button in the menu.
Then after a while, I figured out that when de Dynamic Access Policy said "Unchanged" on the "Access Method" page.
When changing that parameter to "Anyconnect client" the portal is no portal anymore, I immediatly end up on the anyconnect client start.
When selecting "Web-Portal" I get the portal page, but the anyconnect menu is missing.
When selecting "Both-Default-Web-Portal" I get the anyconnect button, and all other menus, which is good.
But, I want the home button to be the default.
And not the anyconnect button, after logging in you immediatly get the start anyconnect page.
And then last but not least, when selecting "Both-Default-Anyconnect" you login to the webportal, anyconnect starts immediatly from the menu.
Something we want the end user to do manually (Click "Start Anyconnect") I mean!
I'm pretty sure the DAP is forcing that because of the options above.
But when selecting unchanged or anything that doesn't include Anyconnect, then the anyconnect button is gone...
I don't know what I can do to change that.
Am I missing something??
I would say DAP isn't needed, but when I set everything to default in the default DAP, then the anyconnect button is gone in the menu...
Kind regards,
Robin

I can't believe it, i serieously though I already did that... And that removed my anyconnect button from the menu.
Which is why I started playing with the DAP function in the first place.
I tried your suggestion and that now works..
Thanks!
The only new problem now is that my bookmarks aren't showing up anymore now.
But that must be a different problem I guess.
Might be DAP related again?
Result: I activated under the default DAP: "Bookmarks" ==> "Enable bookmarks"
Now everything works as it is supposed to...
Really strange though... I thought I did that already...
Thanks jportugu!!

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

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!
EvaHi,
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'.

JoeHi,
As mentioned by Guru, the recommended action is to format the flash: memory.
Sometimes some webvpn files get corrupted resulting in missing DfltCustomization objects or import errors.
Once you format it, it should work fine.
Thanks.

Client SSL Vpn question`
not sure if this is possible /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?I do not know if its just me but I do not understand what you mean with this:
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?
Can you try it to explain it one more time?
Now, I think you are saying the following, please look this:
HQ----ASA----INTERNET----------Office2
Now the Office2 will do a clientless SSL vpn to the ASA and afterwards you want the HQ to be able to contact some printers or servers on office 2 via the clientless SSL vpn, If that is the question the answer is NO. the clientless SSL vpn will only allow traffic to go from office2 to the HQ, and not all traffic, it will depend on what you use to configure the clientless ssl ( Smart tunnels, Port-forwarding,Plugins).
Again I am not sure if that was the question.

Julio
