VPN access to several local networks virtual asa8.3
you are looking for assistance. This one goes batty.
I have ASA 5510 8.3 running
It serves as a router, firewall and vpn.
the underlying network works fine.
When I connect via VPN, I can only access my reseau.41 and not on the reseau.42. When I try to do a ping.42 I get this error:
5 October 18, 2010 00:33:13 192.168.42.11 3389 rules asymmetrical NAT matched for flows forward and backward; Connection for tcp src Outside:192.168.43.200/2916 dst servers:192.168.42.11/3389 refused due to path failure reverse that of NAT
If I flip through these rules in order to config then I can acceder.42 through the vpn but pas.41
NAT (servers, all) static source any any destination static obj-vpnpool obj-vpnpool
NAT (iscsimgmt, any) static source any any destination static obj-vpnpool obj-vpnpool
I'm confused because it's all a new config and I used the wizard in asdm and couldn't access squat (perhaps he does not know how to manage the VLAN)?
the ASA may well ping of all networks.
devices on the network can ping each other fine
just via ipsec vpn, I can't access both networks.
thoughts?
Please configure a more specific NAT statements as follows:
object obj-iscsimgmt network
192.168.42.0 subnet 255.255.255.0
NAT (servers, Outside) source static obj-servers obj-servers destination static obj-vpnpool obj-vpnpool
NAT (iscsimgmt, Outside) source static obj-iscsimgmt obj-iscsimgmt destination static obj-vpnpool obj-vpnpool
And pls Remove the following:
NAT (servers, all) static source any any destination static obj-vpnpool obj-vpnpool
NAT (iscsimgmt, any) static source any any destination static obj-vpnpool obj-vpnpool
Then "clear xlate" after the changes described above.
Hope that helps.

ASA5505 can transfer clients to remote VPN access to the local network
I have currently ASA 5505 and 2911-router and I am trying to configure the VPN topology.
Can ASA5505 you transmit to remote VPN access clients LAN operated by another router?
These two cases are possible? :
(1) ASA 5505 and 2911-router are separate WAN interfaces, each connected directly to the ISP. But so can I connect an other interfaces LAN of ASA 5505 in a switch managed by 2911 router customers to distance-SSL-VPN to inject into the local network managed by the router?
(2) ASA 5505 is behind router-2911. May 2911 router address public ip or public ip address VPN-access attempts have directly be sent to ASA 5505 when there is only a single public ip address address available?
Long put short, ASA 5505 can inject its clients to remote-access-VPN as one of the hosts on the local network managed by 2911-router?
Thank you.I could help you more if you can explain the purpose of this configuration and connectivity between the router and ASA.
You can activate the reverse route on the dynamic plane on the SAA. The ASA will install a static route to the customer on the routing table. You can use a routing protocol to redistribute static routes to your switch on the side of LAN of the SAA.

Cisco ASA 5505 remote VPN access to the local network
I have installed two ASA 5505 VPN site to site that works perfectly. Now, I also need to have 1 customer site to remote access VPN with Cisco VPN dialer. I can get the VPN dialer to connect the VPN and get a VPN IP address, but I do not have access to the remote network. can someone take a look and see what I'm missing? I have attached the ASA running config.
Apologize for the misunderstanding.

Yes, you will need to either configure split tunnel so that internet traffic goes out through your local Internet service provider, GOLD / directed by configuration current you are tunneling all traffic (internet traffic Inc.) to the ASA, then you will need to create NAT for internet traffic.
To set up a tunnel from split:
split-acl access-list allowed 192.168.30.0 255.255.255.0
attributes of the Group mull strategy
Split-tunnel-policy tunnelspecified
Split-tunnel-network-list value split-acl
I hope this helps.

Ipad Cisco ipsec VPN connects but not access to the local network
Hi guys,.
I am trying to connect our ipads to vpn to access network resources. IPSec cisco ipad connects but not lan access and cannot ping anything not even not the interfaces of the router.
If I configure the vpn from cisco on a laptop, it works perfectly, I can ping all and can access resources on the local network if my guess is that the traffic is not going in the tunnel vpn between ipad and desktop.
Cisco 877.
My config is attached.
Any ideas?
Thank you
Build-in iPad-client is not useful to your configuration.
You have three options:
(1) remove the ACL of your vpn group. Without split tunneling client will work.
2) migrate legacy config crypto-map style. Here, you can use split tunneling
3) migrate AnyConnect.
The root of the problem is that the iPad Gets the split tunneling-information. But instead of control with routing traffic should pass through the window / the tunnel and which traffic is allowed without the VPN of the iPad tries to build a set of SAs for each line in your split-tunnel-ACL. But with the model-virtual, SA only is allowed.

Any help or pointers greatly appreciated, I have do this config after a long interval on Cisco of the last time I was working it was all PIX so just need to expert eyes to let me know if I'm missing something.
And yes I don't have a domestic network host to test against, all I have is a switch that cannot route and bridge default ip helps too...
Hello
The first thing you should do to avoid problems is to change the pool VPN to something else than the current LAN they are not really directly connected in the same network segment.
You can try the following changes
attributes global-tunnel-group RAVPN
No address RAVPN pool
no mask RAVPN 192.168.200.1 - 192.168.200.254 255.255.255.0 ip local pool
local pool RAVPN 192.168.201.1 - 192.168.201.254 255.255.255.0 IP mask
attributes global-tunnel-group RAVPN
address RAVPN pool
no nat (it is, inside) static source NETWORK_OBJ_192.168.200.0_24 NETWORK_OBJ_192.168.200.0_24 static destination NETWORK_OBJ_192.9.200.0_24 NETWORK_OBJ_192.9.200.0_24
In the above you first delete the VPN "tunnel-group" Pool and then delete and re-create the VPN pool with another network and then insert the same "tunnel-group". NEX will remove the current configuration of the NAT.
the object of the LAN network
192.168.200.0 subnet 255.255.255.0
network of the VPN-POOL object
192.168.201.0 subnet 255.255.255.0
NAT (inside, outside) 1 static source LAN LAN to static destination VPN-VPN-POOL
NAT configurations above adds the correct NAT0 configuration for the VPN Pool has changed. It also inserts the NAT rule to the Summit before the dynamic PAT rule you currently have. He is also one of the problems with the configurations that it replaces your current NAT configurations.
You have your dynamic PAT rule at the top of your NAT rules currently that is not a good idea. If you want to change to something else will not replace other NAT configurations in the future, you can make the following change.
No source (indoor, outdoor) nat Dynamics one interface
NAT source auto after (indoor, outdoor) dynamic one interface
NOTICE! PAT dynamic configuration change above temporarily interrupt all connections for users on the local network as you reconfigure the dynamic State PAT. So if you make this change, make sure you that its ok to still cause little reduced in the current internal users connections
Hope this helps
Let me know if it works for you

Have problems with the IPSec VPN Client and several target networks
I use an ASA 5520 8.2 (4) running.
My goal is to get a VPN client to access more than one network within the network, for example, I need VPN client IPSec and power establish tcp connections on servers to 192.168.210.x and 10.21.9.x and 10.21.3.x
I think I'm close to having this resolved, but seems to have a routing problem. Which I think is relevant include:

When a user establishes a VPN connection, their local routing tables have routes through the tunnel to the 10.21.0.0/16 and the 192.168.210.0/32.
They are only able to communicate with the network 192.168.210.0/32, however.
I tried to add the following, but it does not help:
router ospf 1000
router ID - 192.168.210.1

Can anyone help me please with this problem? There could be a bunch of superfluous things here, and if you could show me, too, I'd be very happy. If you need more information on the config, I'll be happy to provide.
Hello Kenneth,
Based on the appliance's routing table, I can see the following
C 10.21.9.0 255.255.255.0 is directly connected, DeviceManagement
C 10.21.3.0 255.255.255.0 is directly connected, servers
C 192.168.210.0 255.255.255.0 is directly connected to the inside
And you try to connect to the 3 of them.
Politics of Split tunnel is very good, the VPN configuration is fine
The problem is here

RVS4000 private networking, establishment of local networks virtual need help!
Hello
I live in a two family dwelling house and we share a common Internet fiber connection. In the basement, we have a modem/router (zyxel) which is in mode "bridge." Therefore, only not as DHCP.
Behind this zyxel, we have a Cisco RVS4000 router. Ports 1 and 2 go to the family, and the Ports 3 and 4 go to the B family.
Family A and B have separate routers which are both set to "access point mode. Family has a router ASUS RT-N66U, whereas family B has a dlink DIR-615. The asus has a point "access" mode, while the dlink must be configured manually to achieve this goal. The dlink must also have a static IP address. The asus can receive the ip address.
I have tried without success to reach and beg currently to get help are separate networks for the two families can access Internet, but at the same time, it must be impossible to access VLAN1(Family A) from VLAN2(Family B) vice versa. Which means no communication between the two families through the local network.
I tried different options but I don't know how to deal with the trunk, tag, no tagged etc etc etc. It seems every time that I managed to create two different networks there is accessability/communication between two VLANs, and whenever I managed to give different IP addresses for different ports, i.e. 192.168.10.xx and 192.168.2.xx it is always possible to communicate. What is also happening usually, it's that the Internet is interrupted at the same time.
-What someone would be kind enough to help out me? Since I'm quite not seasoned networking, I need a detailed guide indicating all the actions that I take. If possible also with illustrations.
Any help will be much appreciated.
Hi Andreas, there is no need to configure any trunks or tag all traffic for what you are trying to reach. Circuits and the marking would be only required if family a (VLAN 1) or B (VLan 2) of the family set up the additional VLANs on their access points. Lets say VLan1 of family and the family then wants a Setup VLan 3 and 4 of VLANs on their AP, then you would need to set the line going to the family as trunk and label all traffic. If A family uses only 1 VLan, then it is useless to set up as a trunk line.
I want to suggest to configure all 4 ports of the router as "Untagged" and disable routing between Vlan1 and Vlan2 InterVLan. This should do what you're trying to do.

Client VPN cause loss of local network
When you use the CISCO VPN Client to a remote network, we lose connectivity to the LAN. We RDP on this server and then establish a VPN connection to another location. Once the VPN connection is established, the RDP connection is lost and you cannot ping the local IP of the server, but it is connected through the VPN newly created to a remote site. I know this has something to do with the split tunnels? How can I configure my NIC or properties so that the new VPN connection does not break the local connection? The application is that the local server is running an application that has an ODBC connector to a report data source.
The administrator of the VPN gateway has set up the Tunnel of split for your connection. Then it will work as you need.

virtual vSwitchs & VM with several local networks
Hello. I'm deployment on a tagging environment vSphere VLAN.
I have a lot of blade with 2 network cards Gbps, configured to form a team and connected to the vSwitch0. My port of Service Console´s group is on VLAN2, then I have a few Windows VMs that need to have access to different VLANS. How we configure it?
I have a port group for the VM traffic, with access to the VLAN2, but if some of the VMS need to access a VLAN 2 different, they fail to do so.
The thing is that you cannot configure several VLANS to a port group, and allowing 4095 (all the VLAN) I get no connectivity to the virtual machines.
Any help is appreciated. Thanks in advance.
Why not add virtual nic, then a more virtual machine which needs more access then a VLAN?
VM
-virt. NIC0 - PG VLAN2 - vSwitch0
-virt. NIC1 - PG VLAN10 - vSwitch0
Help?

Remote VPN with PIX without access to the local network
Hi @all,
I ve running into problems and I have not found any solution. Can someone check my config?
Facts:
PIX 501 6.3 (3)
4.04 VPN client
Wanted solution: access to HO via VPN
VPN tunnel will be established, I get an IP address, but I can´t the systems behind the pix and the pix of access itself.
To the VPN Client Staticts, I see outgoing packets, but no entrant (if I send a ping to peer behind the pix)
I hope someone can help me
Attached is my config:
PIX 501 and 506/506e pix are not supported in v7 due to the fact that the cpu is not able to deal with the extended features of v7.
PIX 520 is not supported I guess it's because of the fact that the model is discontinued.

Cisco router access outside the local network interface
Hi all!
I have Cisco router 892 (c890-universalk9 - mz.154 - 3.M4.bin) with firewall area and based on routing strategies.
Everything works fine, but now I need to have the ability to access external router interface IP LAN addresses.
For example, I PAT 192.168.4.1 port 8443 to the outside interface IP (93.93.93.2 for example) and I need to check LAN 93.93.93.2:8443.

It is due to the fact that they do not allow "hair pinning" by default, once this is configured, it will work.

Cannot access files between local network PC
I have 2 computers ethernet under XP Home SP3. They are of type ethernet connected behind a router wireless Airllink 101 a Vista laptop is connected on the wireless (the Vista laptop cannot access files either). At the same time as I had a third ethernet PC connected without SP and I was able to access his files for at least one of the other PCs. I tired remove firewalls (temp) and Virus check without success. In the network section, I can see the computers and shared files on the PC but when I try to open directories is said I can't have permission to use this network resource. Memory: server to process this command. Server? Here is the esentiallly peer computers back-to-back. I have 50 + GB on each PC. I believe that this has happened after that I installed SP2 or SP3.
See the article in the Knowledge Base Microsoft Antivirus software may Cause Event ID 2011 for a likely solution.

Multiple VPN tunnels to a local network
Could someone advise if the PIX will in future support the ability to configure several tunnels which will end on a number of PIX that are all on the same remote LAN? In other words, all the cryptographic access lists will point to the same remote LAN address. The intention is to use another tunnel, if for some reason any tunnel at a site goes down. The main goal wouldn't be redundancy and load balancing.
Thank you very much
Walter Rogowski.
Oh, and it's purely for redundancy. The PIX won't balance the load on both peers or something like that, the 2nd peer never be used if 1 is not available.

Needs inventory of local network VIRTUAL the virtual computer for each network adapter
Hello
I'm looking for VLAN VM inventories for each network adapter, the script lists the following details at the exit of the CSV file.
VMname | Cluster name | Name NIC-1 | Name of VLAN. NIC name-2 | Name of VLAN.
Thanks in advance!Hello
$(gkulikowski #08: 15:06 > get-vm | %{$clustername = ($_ | get-cluster) .name; $_ |}) Get-NetworkAdapter | Select @{N = "Name VM"; E={$_. Parent}},@{N='Cluster'; E={$ClusterName}},NetworkName,@{N='NetworkCard'; E={$_. Name}}}). Export-csv-path c:\out.csv
but it will be output that
Name of the computer Virtual Cluster NetworkName card
------- ------- ----------- -----------So if you have more than 2 NICs for you will see them as well. not in the form of columns but as rows.
OK, and if you want to have in the columns, I wrote like this:
$(get-vm testgk | %{$clustername = ($_ | get-cluster) .name; $ntwkcards = $_______ |}) Get-NetworkAdapter; » » | Select @{N = "Name VM"; E = {$ntwkcards [0].} Parent}}, @{N = "Cluster"; E={$ClusterName}},@{N='NetworkCard 0'; E = {$ntwkcards [0].} VLAN Name}},@{N='NetworkCard 0'; E = {$ntwkcards [0].} NetworkName}},@{N='NetworkCard 1'; E = {$ntwkcards [1].} Name}},@{N='NetworkCard 1 vlan'; E = {$ntwkcards [1].} NetworkName}}}). Export-Csv c:\out-file.csv
It will be the exact release you requested.
'Virtual machine name', 'Cluster', 'Map' 0 '', 'Card 0 vlan' map 1 ","map 1 vlan.
You mentioned the name of vlan, so I guess that you think of the name of portgroup.
