Cisco VPN :: 5520 / Unable To Use Proxy Server With MAC OS X Anyconnect Client?
Dec 13, 2012
I have a VPN setup thru a Cisco 5520, Windows clients connect just find and the end users configure there browser to use our internal proxy servers. Users with the MAC OS X Anyconnect client can connect, they configure their Mac to use our proxy server, but the broswers will not work, clients can reach networks and resources behind the VPN gateway and have access to the Proxy(Tried a telnet to that hostname/port). I am running ASA 8.3(2), Anyconnect(OS X) 3.1.01065.
I currently have a Cisco 5520 ASA which is up and running and the users are able to connect to Anyconnect to VPN into the network. However, users plugged into the internal network inside the ASA are unable to connect to the vpn address and download the Anyconnect Client. I think this may be to do with reverse NAT missing?
I need to activate AnyConnect SecureMobility client on an IPAD. I have an ASA with the below feature licenses:
This platform has an ASA 5520 VPN Plus license
As I've understood that I need the ASA-AC-M-5520 license for each IPAD used but they mentioned that we need also the Essential or premium license to be activated on the ASA as well. As shown above, I have the "VPN Plus license" activated on the firewall.
We are using an ASA 5520, running 8.4(3). We have users running the AnyConnect Secure Mobility Client 3.1.02026. I have the AnyConnect connection profile configured to authenticate users using LDAP over SSL. I enabled the password management and am able to get password change prompts to appear in the AnyConnect client. However, new passwords are rejected and changing passwords through that prompt does not work. I'm not sure what the cause of the problem is, since LDAP over SSL is enabled and working, which is required for the password management feature
I currently have 90 remote locations that have PIX501's. They are all running 6.3 on them. All of these locations are creating an IPSEC VPN to my ASA 5520 (8.4) at the data center. Web access at the remote locations is currently being handled with ACL thru split tunnels. This is getting increasingly not fun as I have to reach out and touch them one at a time whenever I have to allow more access to the net. Code...
I would like to keep my split tunnel (if possible) for ports 443 and 21. I allow access to "any" on those ports and have no plans to change it.
Can I send port 80 down the VPN tunnel to the Proxy/Web Filter and then return the results to the Remote Client.
We have an ASA 5520 with two VPN profiles working fine.Since some users are now working with Windows 8, VPN clients for Cisco ASA is not able to connect.I have read there are problems for such VPN Clients in that OS, and I should use now Anyconnect for them to connect. I thought we had anyconnect working also, because some users can connect to a web page they can do some kind of connections to internal servers, (web, telnet, rdp, etc) so I installed cisco anyconnect VPN client in a laptop and try to connect (same IP and port I used for that web page) but after signing I get the message AnyConnect is not enabled on the VPN Server.So I tried to follow a configuration guide for Anyconnect, but there's a step in which I am trapped, these are the steps: Click Configuration, and then click Remote Access VPN.
we have ASA5510 with version 7.x and asdm 5.X, i upgraded it to 8.3 and asdm 6.2, and i got vpn peers 250 and 2 ssl.when i try to connect through client software , i can see in the logs UDP 500 port is created as shown below. [code]
and currently in right panel of Active Algorithms i have only RC4-SHA1,
I would like to connect devices to my network so that their traffic passes through a proxy running on my computer. I figured the best way to do this is by setting the proxy on my router to the one I am running, but then I would need to have another connection to the computer running the proxy or else there would be an infinite loop ?? something like that. so:
Internet -> router (1) -> my proxy on comp A -> router (2) -> computer B
Profile in atthach-file. After this profile is uploaded to client Optimal Gateway Selection doesn't work propertly: When 'vpn1.mydomain.com/mygroup' (it best TTL server) is unreachable, then OGS try to be connected to other servers, but without group-url, for example 'vpn2.mydomain.com' (instead of 'vpn2.mydomain.com/mygroup')
I ve configures an asa 5505 for remote vpn with anyconnect. it works just fíne - from remote i can ping the Clients and Server inside, i can do RDP or Connect via SSH to any machine, map some volumes local and so on but: I can not connect microsoft sql server. It uses port 1433 for the first connect and establishes then a dynamic connection. So i am a Newbie - what rules or configs do i miss?
Few days ago I started to get the following error message while trying to connect to the internet using Chrome and IE:"Unable to connect to the proxy server..."I don't have a proxy server configured - nothing is checked in the LAN settings page.In Firefox I don't have that problem - it seems it gets the proxy configuration from elsewhere.
i configured cisco asa 5520 as cisco ezvpn server and cisco 891 as ezvpn client .the configurtion is working fine.i am using client mode on the ezvpn client side.but my quesion is , is it possible to communicate to ezvpn client side internal ip from the ezvpn server side?and one more thing what is the benefit of network extension mode on the client side and how it will work what are possible changes need to do in the server and the client side.
We have Cisco ASA 5505 with ASDM 5.2 We have one Proxy server in our Local Lab and pointed to Hosted service(Simple Signal)issue is, When our proxy server send register to hosted server, ASA change private IP and post with outside IP and src port as 1063 every time.
Here is debug log on real time monitoring.

We have ASA 5520 as SSL VPN concentrator so users can access internal web from outside. Our internal web also has several internet URL. What we want is when user click internet URL in our internal web, ASA forward those request to internal proxy server. I already config proxy using port 8080 and username "companyuser" and password, but always have authentication failed on ssl vpn browser. We uses forefront TMG as proxy. Username and password have right to access Internet.
recently i have install asa 5520 (8.2) in my networks.Earlier I was using my transparent proxy with 2821 by the following configuration access-list 120 deny ip host 192.168.112.12 anyaccess-list 120 permit tcp any any eq wwwaccess-list 120 deny ip any any route-map PROXY-REDIRECT permit 10match ip address 120set ip next-hop 192.168.112.12 ip policy route-map PROXY-REDIRECT and was working fine. How i can use my transparent proxy with ASA?
I have a problem with my asa phone proxy. i have two ASA 5520 in HA. I have 10 phone register with ASA active primary. if i execute the command show phone-proxy secure-session. i can see the phone session on the ASA.
if i perform the same command on the passive ASA i can't see the session replicated from the active member.
If i switch the cluster the phone enter in a registrating loop and can't connect to the ASA now active.
If i switch back immediately (the session are still present on the first asa) the phone register again and all works
the ASA have version 8.4(5)
the phone are a 7921g
is normal that the skinny don't start again and re-register the phone on the ASA that became active after failover?
Having some problems blocking users installing/using secure browsers proxy. Currently runing ASA 5520 ver. 8.3 & IPS SSM-20 7.0 (2) E4 & Websense web filtering. Able to block most proxy sites with Websense that use port 80 but recently found that some users using some products like Njutrino that use their own secure browser that use it's own proxy over SSL connection.
2 x ASA5520 with SSM20 . using AnyConnect 3 , users are not getting disconnected from ASA even after the vpn client is closed . Users would not be able to login from the same ip until the session is active. Manual clearing of the session enable the user to log back in .
I've got a short trouble running anyconnect client 2.3.254 under Mac OS X 10.5.6.If I use it to connect an ASA 8.0.4 through a proxy (squid) it doesn't work.If I use Win XP, with same proxy, it works.If I don't use any proxy, with my Mac OS X client (on another WAN access) it works too.So, is anyconnect client supported over proxy server on MAC OS X ???? or did I miss something ?
I have a query regarding MAC authentication for end systems on ASA 5520. Inspite of proving MAC address in endpoint authentication along with AAA, only AAA attribute policies are getting created. MAC authentication is not happening.
Is there any requirement like LDAP or AD is required for MAC authentication?
I have an ASA 5520 soft 8.2(3) when i try to configure the any connect I don't get the SSL and the telnet options for the connection. bare in mind that i don't have the any connect software on my asa nor do i have any certificate. is it essential to get a certificate. do i have to buy it knowing that it will only be used by our company's partners. if not how do i get it
I am using AnyConnect VPN 2.5.3054 on two different computers (Windows 7 and XP SP3) with Kaspersky Internet Security 2012. Upon successful connection, the client disconnects and goes into a continous loop of reconnection to no avail, a message at the bottom appears: "A VPN reconnect resulted in different configuration setting. The VPN network setting is being re-initialized. Applications utilizing the private network may need to be restarted."At times I also see after this loop of attempts to reconnect: "The VPN client agent SSL engine encountered an error. Please retry, or restart AnyConnect."Note: I added the VPN applications to the trusted zone of KIS 2012, unchecked the SSL and HTTPS 433 ports and added exceptions for the applications, again without use. I tried uninstalling and installing after disabling KIS but the problem persists.
Some of my VPN users are getting the following error on Windows 7 64 bit computer. I have uploaded the client to a website. The VPN users are supposed to download and install the client from the web-site. Then they enter the URL to connect to our VPN. This worked fine during the test and only some users are having issues. This seems like Windows issue.
Error “There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personal or package vendor”
We have a RA Vpn split_tunnel setup in one of our locations which is working fine in all areas except for traffic destinged for one specific website using https. This vendor only allows the HTTPS connections to them to come from certain outside IP addresses. ssentially it should work like this:RAVPN_client (10.4.4.0/27) --> https request to vendor_ip (208.x.x.x) ---> ASA55XX --> NAT_to_outside_ip --> https request to vendor_ip (208.x.x.x) need to understand how you would go about NATing ONLY this specific https traffic from the RA VPN while not having to alter the setup otherwise. Internal hosts (aka behind the ASA physically) do not have any issue getting to this site, as its nat'd to the outside ip address as we expect.Here is what we are using for the NAT Exemption list he 10.2.2.x, 192.168.100.x and 172.23.2.x are other remote sites that we have. RA VPN users are using the 10.4.4.0/27 do not have any issues connecting to them, no matter the protocol.
when it comes to IOS based SSL VPN setup, so have run into an issue which I can't seem to find an answer for.
What i'm after is a way to restrict access to an AnyConnect authenticated and connected client, on a specific profile, to a list of specific websites (all on the Intranet). Everything else must be blocked.
On the IOS device, I had it fudged to pretty much retstrict access to a certain IP and port, and used a mod rewrite in Apache to re-write a URL from that IP to the host the site actually resided on. It's cludged together and working, but it's not ideal (and it's not going to allow for scaling up to what I need).
I can find plenty of references here and on the net to using regex to create block lists based on a global policy to disallow specific URLS, but I need the inverse of that, and, only applied to a specific policy group.
Is this possible on an ASA5505? Is it possible on *any* ASA?
I am having an issue I need to have the outside interface terminate a ssl AnyConnect Client. I have several groups the will login and I need multiple inside interfaces to satisfy my security needs.
I have one group call ombudsman-mhdd and they need to go out interface g0/1.231 and another group called oet-router go out g0/1.232.This works on my 8.2 box but I am having trouble routing traffic out these interfaces.
I have noticed that the error "unable to process response from x.x.x.x" when using anyconnect is very common and that the actions to handle it are different. Right know I have the same issue. Let's name it "the message" =)
We are running: ASA 8.2(2) . AnyConnect 2.5.1025
In my scenario, we used to be able to connect to the ASA using AnyConnect but suddenly it stops to work showing "the message" =) We did this procedure, but it did not worked for us
My first question would be: How can I obtain more information so I can get a better idea to handle "the message"?
The next step I am about to do is upgrade the AnyConnect Cliente to 2.5.2019. According to the release notes, this versión is supported with ASA 8.2(22)
I also notice that the AnyConnect client can be install with a component named Cisco Diagnostic and Reporting Tool (DART). Does this tool could be usefull to troubleshoot "the message"? What kind of information does DART can give us? Were can I find the files it captures?
I'm trying to test Anyconnect VPN but after configuring the required configuraiton I'm not getting Anyconnect client downloading and it just log into the clientless webvpn. Below are my basic required configuration. I have tried with few other ASA the same configuration but it worked fine. I'm using the default SSL VPN base license (02) with the ASA5580 code running 8.2.2
We are currently using Cisco VPN Client. I'm looking to migrate to Cisco Any Connect. Our ASA 5520 has 750 IPSec and 2 SSL license. I also have approximately 40 IPSec site to site VPN's on this. ,Will anyconnect interfere with the site to site tunnels?,If I setup anyconnect with the IPSec instead of SSL do I still need to purchase the premium or essentials license?,Lets say if I do have to get the license and I get essentials will it cause any issues with the site to site VPNs?
My client is upgrading from anyconnect 2.5.2014 to 3.1.00495. The ASA is running ASA 5520 version 8.2(5)33 and is in an active/standby failover pair.when trying to push out the new 3.1 from the pair to windows 7 and XP machines, he gets the error "Failed to get configuration from secure gateway. Contact your system administrator". When he tries to push 2.5.2014 and 2.5.6005 out from the pair this works fine.When pushing the 3.1 out from a stand-alone test ASA 5520 it works fine.
