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.
object network VPNPool
subnet 192.168.70.0 255.255.255.0
nat (outside,outside) dynamic interface
same-security-traffic permit intra-interface
I've attached a document showing how this network is designed. A client on a guest vlan behind the ASA, nat'd to one address on the public subnet, needs to be able to get out to the internet, and still come back in for specific services, such as OWA, via the IP which the mail server is nat'd to. The drawing is pretty explanatory. Do I simply need to create a NAT statement and ACL to allow that client out and back in, or do I need to set up hairpinning? I'm working with a Cisco ASA 5505 Version 8.4(4)3.
Note: The drawing has public IP's substituted with 1.1.1.x with final octet being accurate.
I'm not sure if my terminology is correct when using hairpinning but i was wondering if there is any special config needed when you try to access a content rule VIP from a server that's configured as a member of a source group on the same CSS?
So say i have a content rule with a VIP 20.20.20.20 and i also have two servers 192.168.1.1 and 192.168.1.2 that are part of a source group with VIP of 20.20.20.21. My problem at the moment is if from the servers 192.168.1.x i try to ping the other VIP 20.20.20.20 that's configured on the same CSS then it doesn't work and ping fails. The same happens with HTTP traffic to the 20.20.20.20 VIP.
I would have thought that the NAT of the source group would happen before the routing so the 192.168.1.x IP's would be natted to 20.20.20.21 and then passed over for routing where the CSS would see that the VIP 20.20.20.20 is local and it would send it on it's way.
I thought it might be ACL related but i increased the verbosity of acl logging and couldn't see anything in the logs.The source group works fine on it's own and from the CSS itself i can ping the 20.20.20.20 VIP fine. It just seems that from the source group members i can't ping the VIP.
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?
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.
View 1 Replies View RelatedI 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 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?

View 6 Replies View RelatedI 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.

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 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)

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.

We have two ASA 5500 series Firewalls running 8.4(1). One in New York, another in Atlanta.They are configured identically for simple IPSecV1 remote access for clients. Authentication is performed by an Radius server local to each site.
There are multiple IPSec Site-to-Site tunnels on these ASA's as well but those are not affected by the issues we're having.First, let me start with the famous last words, NOTHING WAS CHANGED.
All of a sudden, we were getting reports of remote users to the Atlanta ASA timing out when trying to bring up the tunnel. They would get prompted for their ID/Password, then nothing until it times out.Sames users going to the NY ASA are fine.After extensive troubleshooting, here is what I've discovered. Remote clients will authenticate fine to the Atlanta Firewall ONLY IF THEY ARE USING A WIRED CONNECTION.
If they are using the wireless adapter for their client machine, they will get stuck trying to login to Atlanta.These same clients will get into the New York ASA with no problems using wired or wireless connections.Windows 7 clients use the Shrewsoft VPN client and Mac clients use the Cisco VPN client. They BOTH BEHAVE the same way and fail to connect to the Atlanta ASA if they use their wireless adapter to initiate the connection.
Using myself as an example.
1. On my home Win 7 laptop using wireless, I can connect to the NY ASA with no issues.
2. The same creditials USED to work for Atlanta as well but have now stopped working. I get stuck until it times out.
3. I run a wire from my laptop to the FiOS router, then try again using the same credentials to Atlanta and I get RIGHT IN.
This makes absolutely no sense to me. Why would the far end of the cloud care if I have a wired or wireless network adapter? I should just be an IP address right? Again, this is beyond my scope of knowledge.We've rebuilt and moved the Radius server to another host in Atlanta in our attempts to troubleshoot to no avail. We've also rebooted the Atlanta Firewall and nothing changed.
We've tried all sorts of remote client combinations. Wireless Internet access points from different carriers (Clear, Verizon, Sprint) all exhibit the same behavior. Once I plug the laptops into a wired connection, BAM, they work connecting to Atlanta. The New York ASA is fine for wired and wireless connections. Same with some other remote office locations that we have.
Below I've detailed the syslog sequence on the Atlanta ASA for both a working wired remote connection and a failed wireless connection. At first we thought the AAA/Radius server was rejecting us but is shows the same reject message for the working connection. Again, both MAC and Windows clients show the same sequence.Where the connection fails is the "IKE Phase 1" process.
