Cisco VPN :: ASA5515X - Remote Access VPN Clients / Multiple DNS Suffixes?
Dec 13, 2012
I am setting up a new remote access VPN using the traditional IPSec client via ASA 5515-X runnning OS 8.6.1(5). We require to provide each client multiple DNS suffixes, but are only to provide a single DNS suffix in the group policy.I have tested using an external DHCP server, but using our Windows Server 2008 infrastructure and Option 119 the list is not provided to clients, and I have read that Windows 7 clients may ignore this option anyway.

I have 2 sites :
site A :
ASA 5510
VPN gateway for remote users
LAN 192.168.192.0/22
site B :
ASA 5505
LAN 192.168.208.0/22
Both sites are connected through a site to site VPN.Remote clients (AnyConnect/VPN client) can connect to Site A LAN and see machines on LAN A but cannot see Site B LAN.
Here is a part of my configuration :
On Site A (ASA 5510)
--------------------------------
name 192.168.192.0 SiteA_Internal_Network
name 192.168.208.0 SiteB_Internal_Network
name 192.168.133.0 VPNPool_AnyConnect
name 192.168.133.32 VPNPool_VpnClient

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?

I have a RV082 and several of my remote laptops cannot access my server using its domain name. It can be accessed using its internal ip address. The issue is that you can log onto the server using remote access and the ip however you cannot use any shortcuts using the domain name. You can see the server with the domin name however no access path is available. This is only on a few remote user laptops. Others work perfectly.

I have been asked to set up remote access VPN on an ASA 5505 that I previously had no invlovement with. I have set it up the VPN using the wizard, they way I normally do, but the clients have no access to anything in the inside subnet, not even the inside interface IP address of the ASA. Thay can ping each other. The remote access policy below that I am working on is labeled VPNPHONE, address pool 172.16.20.1-10. I do not need split tunneling to be enabled. The active WAN interface is the one labeled outside_cable. [code]

I've got a Cisco 1941 setup working fine for Cisco Anyconnect. Clients can connect to local resources fine. The issue I have is I need the remote clients to access a third party IP address but to do so they must do it through the VPN. At the moment only local resources are accessed across the vpn and if they need internet they use their own internet connection they are connecting with.I've added the below to make sure traffic going to the IP is going across the VPN.

Just installed ASA -5505 replaced cisco 851
My exchange server hosts remote outlook clients and remote web access
no one on the remote side can access my exchange server
internal mail flows in bound and out bound.
My iphone can not access the exchange server either.
When the Cisco 851 was online all the above worked great. Nothing changed on the remote client side just put the ASA 5505 in service.
I am new to the ASSA 5505 family. Had a reseller configure the router but unable to get them at this hour. Called Cisco support but they are closed at this time also.

I am not sure if what I am trying to accomplish is possible. On my internal network I have the following VLANs setup (102, 104, 106) and they map one to one to a subnet (ie: 102 = 192.168.102.0/23, 104 = 192.168.104.0/24, etc).All interVLAN routing is done on a 3560 via vlan SVI. Connected to the 3560 via a routed port is a ASA 5510. The routed port has IP 192.168.100.1 and the ASA interface on the other side of that routed port has IP 192.168.100.2. I use 802.1x on the wired network to assign users (based on their department) into a specific VLAN. I want to extend this concept to Remote VPN access. Therefore I setup multiple Group Policies (policy is applied based on an LDAP attribute) where each policy defines a different DHCP scope. This has successfully allowed me to login wtih different users who get assigned to different Group policies and they obtain the correct DHCP IP address from the internal DHCP server (ie: an engineering person logins remotely and gets an IP in 192.168.102.0 range). However the issue (and as I was planning this out I knew this would come up) is that traffic can be routed out from the VPN client to its destination but there is no return path.

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.

Is it possible to set up a pppoe client on a VLAN interface, or a switch interface associated to an VLAN?. For example, in a 881 ethernet router, could I configure a pppoe client on any of the lan interfaces in addition to the pppoe client configured on the WAN interface?.

I've inherited some ACS appliances from another part of my organization. I need to keep most of the settings but want to remove all the AAA clients; and preferably not one-by-one. I don't see a way in the documentation and web searches have proven fruitless.

I just want to keep one PC as a server and one switch connect to it (For LAN). I want to connect multiple client/screen to that server, so I can use single servers for multiple screen/client.(Client machine will not have any CPU, they will utilize servers memory.)

I have a 4402 which is connected to a 4506 Switch int Gig 3/1 via a trunk port. The Managment and AP-manger interfaces are on vlan 6 [code] I have a 1142N AP also connected to the switch and it pulls a DHCP IP Address and configs etc and registers to the WLC. It too is on Vlan 6 and it is connected to the 4506 on int gig 4/33 which is an access port. [code] I am doing local authentication, so i have added users to the WLC.. My problem is that the first client that connected was able to get an IP address and connect to anything internal and external.I then connected another client on another laptop and that client could connect but not get an IP address, it just self assigned.When i look at the clients i can see the MAC address of both Clients on the WLC, but doing a show mac address-table dynamic i only see the MAC of the client that works properly. The client that doesnt get an IP has no entry in the 4506 switch.I am stumped, from what I understand, is that the 2nd clients traffic is being trunked to the WLC , hence it has the MAC address. But I dont know why its not getting a DHCP assigned IP address.

I'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)
#pkts encaps: 54712, #pkts encrypt: 54712, #pkts digest: 54712
#pkts decaps: 31893, #pkts decrypt: 31893, #pkts verify: 31893
#PMTUs sent: 0, #PMTUs rcvd: 0, #decapsulated frgs needing reassembly: 0
current outbound spi: A4FA947A

All the SOHO routers I have used had a table which shows IP, MAC, Name, etc. In this table, I could easily put a check mark to a check box in a row that I would like to bind/reserve and IP would be reserved for that specific MAC.
In ISA570W, when I need to reserve/bind an IP to a MAC it asks me to fill out a table in which I have to manually type in the name, IP, and MAC.
Is there an easier way?Is there a way to do the reservation for multiple clients at once?If this is the only way, do I need to copy the mac address of each client somewhere and then reserve IPs for each one manually? This method looks very far from user friendly and efficient, unless there is a very logical reason that I cannot think of.

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 am trying to understand how to remote control a clients computer through the internet.
I have Symatec PCanywhere installed on both When i'm on the same connection (wireless internet).I can get it to work no problem.However when I try to remote in using a different internet connection it does not go through.
I've done some research and found out that instead of using the IP address it gives me (dynamically) [192.168.2.5] i need to aquire the WAN IP address from a website or through the router. As well as configuring virtual server through the router, and enable port forwarding in some way or another for specific ports.

I have a WPA2/AES network with PEAP MsChapv2 authentication. I have 2 ACS servers for authentication. The problem I have is dropped clients. Both ACS servers are setup identical. The database replcation has been preformed.A series of 10 clients connects wirelessly and they are all successful. ACS server 1 is the primary and ACS server 2 is the backup. We verified that the 10 users authenticated to the primary ACS. My time out to reauth is 30 minutes on the WiSM. 10 minutes into the test we took down the Primary server. This should have had no impact on the clients. 5 minutes later the clients lost thier authentication and were dropped from the network. They were able to reconnect by shutting down thier wireless client and reconnecting. The authentications were seen on the Backup ACS server.on a test of falling back to the primary the same thing happened again to the clients.

I.e. supporting these client options: "Send all traffic" (Mac/iOS), "Use default gateway on remote network" (Windows).

Im facing with some DHCP lease issue and its like this,Our Cisco 2951 edge router is configured with local dhcp pool for a set of remote users when they connect through Cisco VPN which was working fine until we planned to change it to a Windows box that is configured for DHCP.The basic idea now is to relay the DHCP requests that are coming from the remote clients through Cisco VPN to the DHCP Windows server. So we added the scope on the server and changed the client config on the router as follows (highlighted is the dhcp relay config). [code]

I'm working with AnyConnect for the first time (my prior experience is with IPSec client) and I have multiple remote users who connect to a 5520 via AnyConnect client; they need to print to each others' shared printers but currently have no connectivity between each other.
Can I configure the 'intra-interface' command to enable connectivity between remote clients, or is there more that needs to be done to enable this, presuming that it can be done at all?

I am installing 2 ASA 5505s at home offices with dynamic IPs. The EasyVPN server is a ASA585x. I am using the 5505s in NEM mode. I configured a unique DHCP scope on each 5505. I have a dynamic crpto map on the server. I configured unique tunnel groups, group policies and usernames for each site on the server. This seems to work fine. Is it normal to configure unique tunnel groups, group policies and usernames for each remote site?

I have an ASA5510, and site-to-site VPN with several remote clients. I have to add another client but their network range overlaps an existing tunnel. Both are using 172.16.0.0/16. I would like to 1-to-1 NAT them as 172.17.0.0/16.
Is it possible to perform the NAT on my device, post-decryption, or is it necessary that I have them perform the NAT at their end?
