Cisco :: ASA5520 - Implementing VPN For Remote Users?
Apr 25, 2012
I have roughly 50 users that are remote, and use VPN to access the resources in my network such as file servers, application servers etc. We currently use Microsoft VPN to authenticate those users. It works, but I am not a fan on Microsoft VPN.
I have purchased an ASA5520 to replace my crappy layer 3 HP core backbone switch, and plan on replacing my Microsoft VPN with Cisco VPN. I want to configure my ASA so my remote users can continue to VPN into my network securely?Is this possible?
i configured a remote VPN on cisco ASA 5520 and everythings seems to be working fine...DHCP IP were been lease to users that connect to the VPN. but the issue now is that our customer want a static IP to be given to a particular user when he connect via VPN.
We are trying to add an additional LAN-to-LAN IPsec VPN to our network. We currently have one remote office connected, when we configure the second VPN matching the first the tunnel never begins to establish. There is an ACL that is dening the static IP for our remote office.
The layout is as follows:
Main office = ASA 5520 Remote Office A = ASA (Unknown Model) Remote Office B = Adtran Router
All devices have static IP addresses.
We used the ASDM VPN wizard to create both VPN's.
We have created a rule allowing all traffic from our remote office IP, and that had no effect on the VPN aside from eliminating the following message from our logging:
We have verified that both sides are configured the same however the VPN never is initiated so as of right now the ASA is simply blocking all attempts from our remote office to connect.
best way to migrate to a new pool for remote access DHCP address assignment. We are currently using a /24 pool, allowing us 253 IP Addresses... during the recent hurricane we hit 250 IP Addresses used, and had to start asking users to connect to our backup ASA VPN device in another country, not an ideal solution. I'd like to expand our current VPN subnet to a /23, however I do not have a free /24 subnet above (or below) our current /24 subnet.
I can certainly allocate a new /23 subnet, but I am looking for the best migration plan with minimal downtime (no downtime would be preferred). Can I just add the new pool range to the tunnel-group RAVPN general-attributes section alongside the current pool, or should I just remove the old pool, log off all existing remote access VPN users and have them log on again to start using the new pool?We are running ASA Version 8.2(1).
in our VPN configuration (ASA5520, Anyconnect VPN Client), we have different VPN User Groups. These Group Policies are retrieved from an LDAP Server.We'd like to restrict the acess like this:
A Group "Home User" might establish a VPN from anywhere on the Internet
A Group "restricted 3rd party" should only be allowed to establish a VPN from their specific public Source IP Address on the Internet (the public IP Address of this 3rd party Company). When these Users try to connect from any other IP Address on the Internet(Home, hotel, etc), VPN Access should not work!
On our old solution, we were able to limit the remote access network, per user group, to some source IP's.
The IP Filters related to group policies in here seem only to be filters concerning the VPN Address (after the VPN is established: where can this user group connect to). But I did not find filters/access lists, where yoiu can define/restrict public access networks for some groups.Or is it possible to do that by Dynamic Access Policies? How?
We have an Active/Active ASA 5520 setup, as i know in Active/Active setup there is no remote VPN access, So i could overcome this limitations?I have a solution but i dont know if it is ablecable or not? we have a spare ASA 5510, so i can use it behind Active/Active Firewalls and assign a public static NAT IP address to it and open all IPSEC and VPN ports and let the remote users to connect to it, is this ablecable setup or not?
Our customer has an ASA5520 Security appliance, I have already config the remote vpn in asa , user can logon via internet by vpn client and can access internal network,customer hope us can make some configuration if the remote user logon asa by vpn and notify them someone login their vpn by email .
I have set this up on pre 8.3 code and 8.3 code as well. I have the following configured on the ASA, but it is not working and I am not seeing the ASA trying to NAT the VPN pool IP address that the client gets assigned.
One of our accounting administrators will be working in our server this weekend from his home remotely. He wanted to know if there was a way I could temporarily lock users from remoting in a few days to prevent them from messing up his work.The only way I could think of was disabling the accounts in Active Directory and then re-enabling them once he was done. Server is running Windows Server 2003 with the users remoting in via RDP. They all have accounts in Active Directory.
I have setup an SA520W and configured SSL-VPN for our small business. Everything seemed to go smoothly and I tested SSL VPN by logging in and playing around a bit which seemed to be fine. However, shortly after deployment I started getting complaints about it being much slower than our old VPN through the consumer grade router I just replaced. I investigated and tested with IE8 and Chrome on Windows XP 32-bit with several different machines, and in all instances it did seem very slow indeed. While looking around I noticed that the Task Manager under the Networking tab shows the SSL VPN connection as VirutalPassage at 64 Kbps. Going into Network Connections shows VirtualPassage under the Dial-up heading with device name Virtual Passage SSLDrv Adapter. Additional properties describe it as an ISDN channel. I have attached an image of the Task Manager pane.The router is running the latest firmware of 2.1.51. It is connected via a static IP that does not require a login, to our dedicated 5 Mbit / 5 Mbit ethernet over copper link to our ISP. We get great speeds and low latency through everything but SSL VPN connections. I haven't done anything fancy so the router certificate is the factory default. Currently we are using the existing 2 SSL VPN licenses that come with the router until we need more access, at which point I want to upgrade to the 25 user bundle. However, I don't feel comfortable upgrading until I get this resolved, because 64kbps simply cannot work for us for a VPN solution.how to configure the SSL VPN to not limit at 64kbps? My engineers are making fun of me for bringing us back to dialup, and I have to agree with them!
I need a way to block MAC OS X users connecting remotely to our coporate users over VPN. I know there is an option to block connections based on VPN client Version, but cant find a way to block users based on operating system.
We use Cisco ASA 5510 firewals one with v8.2(1) and other with v7.2(3). I need to do on both firewalls. They are both at diffrent sites.
can i have 2 pools each with diifferent subnet [code] i wanna put restricution on remote vpn users having address from pool-2,and just give them access to 172.16.10.0/24,is it possible on the asa 5510?
We have a high availability pair of ASA 5510's in Data Centre where we have configured remote access to allow users log in via SSL VPN, now we want to add further security to our environment we are adding endpoint assessment licenses...the question I have would I need two sets of the license ASA-ADV-END-SEC ?
I learned the hardway before with ASA SSL VPN licenses breaking other failover pair as it needed identical licenses on both units! Will I need 2 separate license sets to keep my firewalls in a HA pair?
I have a problem on a Cisco ASA5520 version 8.2(5). A customer has set up a syslog to keep tracks of tcp sessions made by vpn users. On the syslog we filter %ASA-6-302013 and %ASA-6-302014 log messages, respectively: Built inbound TCP connection and Teardown TCP connection. When the connection is made by a vpn user, at the end of the log line you see the vpn username which should be the same in both the messages for the same connection. I have verified that when a user, let's say UserA, disconnects from the vpn, their tcp sessions are not properly closed; if another user, let's say UserB, establish a VPN immeditaely after and gets the same IP address previously assigned to UserA, the log sessions are recored with UserA in the %ASA-6-302013 message and UserB in the %ASA-6-302014 message. I presume this is due to the fact the tcp sessions are not tore down when the first user disconnects and it looks like a bug to me but I didn't find it referenced anywhere. Is there a way to have all tcp session tore down when a user disconnects the VPN connection?
I am using my ASA 5505 to remote VPN. I use both windows and Macs. I use the Cisco VPN client software on the windows machine, on the Mac I have used both the Cisco VPN software and the built in OS X VPN client.
I am able to VPN with all machines, but randomly the VPN will disconnect all users. I know there is a setting that may fix this which I think I tested in the past and it did not work, but I have now forgotten it.
I was trying to access some computers in network via remote desktop. All those computers had been used by other staffs.What I noticed that, for some computers I can access via remote desktop by forcing them to log off (people who were using the computers)But for some computers, I got the message similar to "user is currently logged onto the computer, you are not allowed to connect"I want to force them too and access these computers. How I can do it?
I have five (5) sites all connected via static VPN tunnels. They are all using Cisco ASA 5510s running 8.4(4)1. Any internal IP on each site can ping any IP on a remote site, because of the static VPN tunnels. I have the external IP (routeable) addresses connecting to each other.
Site A: 10.1.0.0 /24 Site B: 10.2.0.0 /24 Site C: 10.3.0.0 /24 Site D: 10.5.0.0 /24 Site E: 10.10.0.0 /20
I have remote users who connect using Cisco AnyConnect 3.1 to Site E. They get a static IP within the 10.10.100.0 /24 subnet (vpnpool00) and can access anything in the 10.10.0.0 /20 subnet. So far, so good.No management wants users to access devices within the other sites, specifically Site A using teh same AnyConnect connection. In other words, they get an Ip address of say, 10.10.100.5 and now need to access a server on Site A's subnet or 10.1.0.5.I have checked my NAT statements and they appear to allow this, but so far when I do a ping I get the following: Routing failed to locate next hop for ICMP from outside: 10.10.100.5/1 to inside: 10.1.0.5/0 What am I missing? Is there a NAT statement that is wrong, or an access-list statement or possibly a static route?
I have a weird problem which I have already submitted a TAC ticket about. When users authenticate through AnyConnect into our HQ ASA 5510 they grab an address from 172.16.254.x. What we have been noticing intermittently is that when logged into our network through the client they are unable to access their resources at one of our remote offices which is connected over l2l to the HQ ASA. This problem just started randomly a week ago and we have been working with Cisco trying to create a solution.
My quick fix is logging into a device at the remote office which is trying to be accessed and pinging the gateway of the virtual subnet for AnyConnect users. When I ping 172.16.254.1 it goes through after a few dropped icmp packets and then the issue is resolved for about 8 hours or so.
how to disable XAuth for Remote VPN users on the ASA 5510 running 7.2(1)?
HPMFIRE(config)# tunnel-group vpn3000 general-attributes HPMFIRE(config-tunnel-general)# authen HPMFIRE(config-tunnel-general)# authentication-server-group none ERROR: The authentication-server-group none command has been deprecated. The isakmp command in the ipsec-attributes should be used instead.
--[code]....
I couldn't find anything under isakmp to disable it.
Currently we have a CISCO 3020 VPN Concentrator to terminate Lan-to-Lan tunnels and have our mobile workers connect via CISCO VPN client (300 users-employees and contractors-). Since this device is coming to an EOL this year we purchased a CISCO 5520 (below are the current licenses on it)
The licensing seems rather complicated, therefore this is my question:
- What VPN solution do you recommend for our users and contractors? it is my understanding the CISCO VPN client does not work with ASA 5500 series devices
- Is there a license needed to deploy VPN solutions for our remote users(employees/contractors)?
My company is using an RV016 router as a gateway to our internal network. My end goal is to allow remote users to access network shares via Samba.I've been trying to create a VPN using the router with absolutely no luck. I've tried QuickVPN. I've tried creating a client-to-site group vpn. I've tried creating a client-to-site tunnel vpn. I've tried pptp. Nothing will allow me to establish a VPN connection. Sometimes there is information logged in the router but most of the time there is not.
We have a Cisco secure VPN site to site tunnel between the 2 locations.Which ports are need to open on tunnel so that users can successfully use OCS over the site to site VPN tunnel.All the users are havning the main brach AD account.Using Wireshark captured the packets, found only port TCP 5060, after allowing this port over tunnel I can see the authentication window.The user authentication fails. Already port 3389, 80, 443 are allowed.The main requirement is to only have the Chat, Group Chat and file transfer. Not require AV traffic.OCS is using TCP. no TLS is configured.
we have two ASA 5510s one in 8.4(4) and one in 8.2(5) in a site-to-site VPN setup. All internal traffic is working smoothly.Site/Subnet A: 192.160.0.0 - local (8.4(4)) Site/Subnet B: 192.260.0.0 - remote (8.2(5)) VPN Users: 192.160.40.0 - assigned by ASA When you VPN into the network, all traffic hits Site A, and everything on subnet A is accessible.
Site B however, is completely inaccessible for VPN users. All machines on subnet B, the firewall itself, etc... is not reachable by ping or otherwise.There are also some weird NAT rules that I am not happy with that were created after I upgraded Site A ASA to 8.4
Site A internal: 192.160.x.x External: 55.55.555.201(main)/202(mail) Site B (over site-to-site) is 192.260.x.x External: 66.66.666.54(all)
I pretty much just have the basic NAT rules for VPN, Email, Internet and the site-to-site.What do I need to add for the VPN to be able to access the site-to-site network?
Remote-access users aren't able to reach our remote network through a site-to-site VPN tunnel between two ASA 5505's.
I've seen several threads about that here, I've run through the walkthrough at [URL] I've taken a stab at setting split tunnelling and nat exemption, but it seems I'm still missing something. Remote-access users can reach the main site, but not the remote site.
Remote-access (vpn-houston) uses 192.168.69.0/24. The main site (houston) uses 10.0.0.0/24 The remote site (lugoff) uses 10.0.1.0/24
We have a site-site and remote vpn configured in same interface in ASA 5520 ( software version 8.3 ). When Remote vpn users try to connect to computers located on the distant end of site-site VPN, their request failed. I tried No-Nat between remote vpn private IP to the remote site private IP, also stated the same in Split tunneling. I cant find even the tracert, ping also timed out.
Based on my diagram, my computer A (192.168.100.11) can ping and access my computer B (192.168.10.14). But, when i'm home and i use remote access vpn (192.168.200.x) in cisco asa 5520 to connect to my computer A is okay. But, when i try to ping my computer B is not okay. I already do the exemption for 192.168.100.x and 192.168.10.x in nat rules for inside interface (192.168.100.2) ...
Should i put routing from outside 1.1.1.2 to 192.168.10.x by using 192.168.100.1 as a gateway?
The desktop team has asked me to set up multicast in our network with building PC's as they will be deploying a few hundred of them starting in two weeks. We currently do not have multicast set up, and the only experience I have with it was during my certification studies, so I have a lot to catch up on quick. They will be sending the build traffic from a single server. The network environment is simple: a 3750 stack as the router/distribution layer and mainly 3550's as access. The PC's that they will be imaging will be on one VLAN that is already designated for PXE builds. This VLAN is across multiple switches. Is it possible to just enable the multicast features on a single VLAN? I have been reading around but not finding much other that very in-depth Cisco papers.
We have backup and other traffic over our vpn which is affecting our ip phone service between two sites. Our consultant suggested implementing QOS over the VPN to give the phone traffic priority. Is this possible with the rvs4000. Is there any good source saying how to do it. Is the setup of the QOS on this router similar to another router where this has been discussed.
I have a problem implementing a NAR for a specific device group. I am running Cisco ACS 4.2 and it works fine for all the other stuff I do but this issue is perplexing me a bit.
I have a device group with Juniper devices in it and I authenticate using RADIUS (Juniper) as the radius setting. I have a Administration user group set up.
I placed a NAR into the group "Per Group Defined Network Access Restrictions" specific to the device group with * for port and address
I placed this group into both the Define IP-Based as well as the Define CLI/DNIS-based section.
No matter what I do I keep getting authenticated.
When I go to the passed authentications page I see my login and the group-name is identified correctly and the network device group is identified correctly too. The filter says "no filters activated". So how can I get this NAR to kick in? I would like to restrict one device group from a ACS user group.
