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.

I need to open a port in a Cisco 2911 router to permit the conexion to an equipment that is inside the LAN, but I my configuration doesn't workt.

I have a Cisco 2911 router and a Cisco 2960 switch at a remote location.I have a user who will work out of this office a few days out of the week and will need to obtain the same IP address everytime the user visits this office. This office has no file server, no dhcp server. I have the user's MAC address and for now, the user is getting an IP address that is leased for 30 days. I'm trying to find the best way to configure either the router or switch or both so that each time this user connects to this office, that user device will always pull the same IP address and of course no other device will use that IP.
I've did some research in creating a small vlan possibly, and assigning it specifically to the port# that the user's desk is at, but not sure if that's the best way or exactly sure how it'll work. I'm currently studying for my CCNA so this is all new to me and I'm trying to do research and test without obviously causing production issues especially given this is a remote site and I access these devices via putty. I can however drive to the site if needed for testing, but I'd like to have a good grasp on what method I'll be using that will work before I actually make the trip.
In my live VPN concentrator at work, my 5520 is showing a static route for each VPN client that is connected to my SSL vpn right now. This kind of confused me because wouldn't only one route to the address pools subnet be needed for my vpn users?
View 12 Replies View RelatedAfter trying to configure remote client VPN access to a Cisco 2911 ISR using the CLI I tried to use the Cisco Configuration Professional. However, either way I have the same problem. A client can successfully connect and access servers but just once. When the client disconnects and tries to connect again there is no access to the servers even though the VPN tunnel appears to be up. I've tried multiple versions of the Cisco vpn client SW and all behave the same: 1st connection can access servers, subsequent connections can't. I've also tried a second (different) client after the original connection and still no luck. If I reload the router the client can get the vpn connection and access the servers but if the client disconnects from the vpn and tries again there is no access to the servers.
I've also tried it with and without NAT but it doesn't seem to make any difference.
The config generated using CCP is as follows:
version 15.0

I have just purchased an ASA 5505 for my remote users to access our internal network. I have followed all the setup instructions I can find. I am able to establish a VPN connection using the Anyconnect client and can see some of my internal network. (Basically, only the subnet of the internal interface) However, I have several subnets inside my LAN which are routed by another switch inside my LAN. I have built in the correct static routes so that the ASA will send traffic to that intenal routing switch for any subnets not part of it's inside interface subnet. I can see and ping those subnets from the ASA itself but the AnyConnect clients cannot.
View 9 Replies View RelatedWe have a Highly available VPN infrastructure across two data centers. We also use ACS 4.2 servers for authentication. The ACS servers are in teh same "cluster" in a Primary and Secondary fashion. Site A has primary ACS and primary ASA 5550 IPSec VPN termination. Site B has secondary ACS and redundant ASA 5550 IPsec VPN termination. We also use InfoBlox for DHCP IP address assignments. The two IPSec VPN Head end devices, ASA 5550s, they use different subnets for IP pools for the VPN Clients. Site A uses x.x.24.0 and Site B uses x.y.24.0. As indicated VPN clients authenticate using teh ACS 4.2 Radiius server. I can assign static IPs per user on the ACS server but this can only work for the primary site. Once static IP address is assigned on primary ACS for a user, this status will be replicated to the secondary ACS on Site B. When the Primary IPSec VPN Head End ASA or Internet fails on Site A, Clients on DHCP will work fine seemlessly via Site B. But for the static IP users, you have to change the Assigned Static IPs to match the subnet on Site B. How I can assign static IPs to clients via both Sites without manual intervention. Either via DHCP or ASA. I was trying to stay away from creating multiple Groups for VPN and also avoidng creating local ASA users because these options will not scale well as static user base increases. I need users to get a static IP address from Site A subnet when connected to Site A and get a static from Site B subnet when connected through Site B.
View 1 Replies View RelatedWe already have IPSEC VPN connectivity established between sites but would like to introduce some resilience/redundancy at a remote site.
Site A has an ASA with one internet circuit.
Site B has a Cisco 2911 with one internet circuit and we have established site-to-site IPSEC VPN connectivity between the 2911 and the ASA.
Prior to getting the new internet circuit, Site B had a Cisco 877 with an ADSL line which are still available but aren’t currently in use.
The internet circuit at Site B has dropped a few times recently so we would like to make use of the ADSL circuit (and potentially the 877 router too) as a backup.
We thought about running HSRP between the 877 and 2911 routers at Site B and, in the event of a failure of the router or internet circuit, traffic would failover to the 877 and ADSL.
However, how would Site A detect the failure? Can we simply rely on Dead Peer Detection and list the public IP address of the internet circuit at Site B first with the public IP address used on the ADSL line second in the list on the ASA? What would happen in a failover scenario and, just as important, when service was restored – I’m not sure DPD would handle that aspect correctly?
I’ve read briefly elsewhere that GRE might be best to use in this scenario – but I can’t use GRE on the ASA. I have an L3 switch behind the ASA which I may be able to make use of? But I don’t want to disrupt the existing IPSEC VPN connectivity already established between the ASA and the 2911. Can I keep IPSEC between the ASA and 2911 but then run GRE between the L3 switch and the 2911? If so, how would this best be achieved? And how could I also introduce the 877 and ADSL line into things to achieve the neccessary redundancy?
I am having cisco 2911-sec-k9 router.
And I got 2 internet connections from isp one is static ip leased line and the other one i dsl dynamic ip one.
What I want is i need to configure internet load balance between these 2 internet and also i need to use static ip for remote access vpna and for my exchange port forwarding.
My dsl line in 100 mps and my leased line 2mb dedicated.
I configured the router as with some example config i got on internet my internet is fine but load balancing not happening and i configured the REMOTE ACCESS VPN . I am able to connect the remote access vpn but no communication through remote access . i cannot reach any device through remote access.
Note: if load balancing is not possible how i can configure for internet traffic use dsl line and for remote access vpn and live exchange port forwarding through leased line.

I am attempting to get a solid setup for a remote office we have going up and I am running into little issues that I cant seem to get around.
Basically, we have a remote office that will have dual ISPs, one hard wired circuit from a local carrier and the other will be a Verizon 4G router that plugs in via Ethernet and hands out DHCP to my Cisco router.The Cisco router is a 2911 with IP SLA configured. I have it setup to ping my DC out one interface and if that fails, it removes the default route and injects a new default route from the other ISP,
The problem I am having is with the VPN. I figured using EZVPN would be the only solution because the Verizon 4G only supports DHCP so I have to be able to connect from a dynamic remote host. The other caveat is that failover needs to be seamless as we have no person onsite that can troubleshoot. Its fine if it takes a few minutes, but the VPN just needs to come back up on its own without any intervention.
I attempted to setup two different EZVPN crypto maps on the router but realized you can only have one inside cryptomap per interface, which would cause a problem with the internal network. I thought I could just create subinterfaces off the router to have two inside interfaces to work with but that wouldnt have supported because they would now be on different subnets.
I decided that adding an ASA5505 behind the router may be the simplest solution. Use the router only for the purpose of handling routing between the two ISPs and performing NAT out the interfaces. Then use the ASA to do EZVPN from. This works well but there are some issues I am trying to work through.
First, when the ISP fails over to the backup, the NAT translations have to timeout before things start working again. For a constant ping, this is fine, I have the timers set down to 15 seconds for NAT timeouts and after 15 seconds the ping picks right back up again. However, this breaks the EZVPN. The ASA keeps trying to bring up the ISAKMP nearly every second, which keeps resetting the countdown on the NAT timeout for the remote EZVPN server. Because of this, the VPN will never come up until I manually clear the NAT translations on the router. So my first question is this; is there a way to adjust the timer that the VPN uses to try to bring the tunnel up? I tried the crypto isakmp keepalive command but that didnt work, it looks like it doesnt work with EZVPN.
The second issue is really with the IP SLA and is only an issue because of the first issue I mentioned. When the router first comes up after a reboot, both the primary and secondary interfaces come up. However, since the primary default route is only injected into the routing table once IP SLA is up and can reach its destination, the secondary route gets injected initially and the VPN comes up over the secondary ISP. In a few seconds, the primary default route is injected, changes the path and because of the NAT translation, breaks the tunnel and never comes up again because of the first issue with the VPN tunnel renewing the NAT translation continuously.
I could easily go out and purchase a $100 Linksys router that will do the failover and clear its NATs and everything, but I need better reliability out of the hardware than that. There has got to be a way to do this on a Cisco device since consumer level equipment can.

View 2 Replies View RelatedI've some strange problems with multiple ASA (NEM) VPN remote clients (v8.4.5). On the HQ I've an ASA5510 (v8.4.5) with multiple NEM's connected to it. The group policy used on the HQ is configured for split tunneling. Now here's the problem;
The remote ASA (NEM) constructs easily a VPN connection to the main location; it seems that everything works well. Traffic through most of the tunneled networks works perfectly. Traffic to certain subnets or hosts brings me into trouble, there is no traffic flowing through the tunnel at all!
When using the command "show crypto ipsec sa | i caps|ident|spi” I can see all of the tunneled subnets. The subnets that works perfecly gives me the correct "local and remote ident" output. The subnets with problems gives me wrong values in the "remote ident". The remote ident should be the IP address of the inside LAN (of the remote NEM) and not the IP address of the ouside interface (of the remote NEM). How is this posible?
Here's is the crypto ipsec sa output:
Result of the command: "show crypto ipsec sa | i caps|ident|spi"
local ident (addr/mask/prot/port): (10.200.60.0/255.255.255.0/0/0) <-- this is the good subnet of the inside interface (NEM)
remote ident (addr/mask/prot/port): (10.100.2.2/255.255.255.255/0/0) <-- this is the good subnet (HQ)

We have remote VPN setup with Cisco ASA 5510. By using VPN filter, I can follow the guide and make client to use all necessary server services. (dns, ssh etc). However, is there any way that allow inside server access remote VPN client's services, ex. let inside server ssh to remote VPN client? Consider remote access VPN filter ACL's syntax, I have to always let source be the "remote VPN client PC", the dest is "inside firewall server", how can I let the other way traffice going?

I have an ASA 5520 8.2(3) and allowing my remote client-to-site-vpn clients to access resources directly connected to my ASA on separate lower security interfaces (not the outside) besides just clients on my internal networks. Someone mentioned to me configuring 'VPN on a stick' however from what I've read this seems to be only applicable when it comes to split-tunneling back out the outside interface (could be off on that). Is this possible on other lower security interfaces as well, and if so what would a mock config that accomplishes that look like (acl's, nat, etc)? Also, if I want internal users to be able to connect to these remote clients once they are active, are there any nat statements necessary (such as nonatting them) or are the vpn clients just seen as internal clients from the rest of the internal network's standpoint by default?
