ASA 5510 VPN dedicated Internet connection
I have a 5510 ASA with a second internet connection on his way. I would like to have an internet connection dedicated to my VPN Site to Site traffic and the other left to manage the public internet traffic. I know that I can do this with a static route, but today, I noticed the "tunnel" option How exactly does the tunnel option work mode and it works better for my situation?
Rob,
(Simplification) "Tunnel" option tells what to do with traffic, once it has been for example inbound VPN decapsulted.
In your case, static routes for remote tunnel endpoint + RRI points will do.
M.
Edit: I would advise yo forget about the end of the dynamics of peers (dynamic IP L2L or ezvpn) solutions on any interface that does not have a default route on this subject.

Cisco ASA 5510 VPN Site to Site with Sonicwall
I am trying to configure a tunnel between a Cisco ASA 5510 VPN (Version 8.2 (2)) and TZ200 Sonicwall. I rose tunnel and go and I am able to ping the internal IP address of Cisco ASA of the Sonicwall LAN but nothing work. When I try to ping a host behind the Cisco ASA of the Sonicwall LAN I get the following message "rules asymmetrical NAT matched for flows forward and backward; Connection for tcp src outside:10.20.10.x/xxxx dst inside:10.20.2.x/xxxx refused due to failure of reverse path of NAT"on the SAA
Googling the error above shows the problems with version 8.3 or later that resembled the nat commands have been changed SAA, train is still on 8.2 but I another common question does not add an exemption of NAT I have double-triple checked that I did add an exception rule of NAT of the hosts on the network from cisco for the guests of the Sonicwall network. Looks like I hit a road block so any help would be appreciated. Thank you
Here are a few excertps of the config file (10.20.2.0 behind the cisco) and 10.20.10.0 behind the sonicwall

Hello Manjitriat,
Okay, detected IPSEC parody is normal, that means you are trying to send unencrypted on a line of encrypted packets.
Now, if you see on the plotter of package that traffic will hollow the VPN channel all its fine in your site.
Now the packet tracer must be something like this:
entrance to Packet-trace inside private_ip_lan destination_private_ip_lan 1025 tcp 80
Please provide us with the result of the following instructions after you run the packet tracer.
See the crypto Isakamp SA

Hi all.
I search the internet to find a way or all first, whether it is possible to do what I want to do, but I can't find anything corresponding to what I'm looking for. Possible that I don't have the right keyword.
We change our old Pix 515e this weekend and for any new ASA 5510.
With this new facility, I want to implement Radius Authentication for the user remote vpn. Change the firewall of the company is an important factor and for the first phase, the user will keep authenticate locally but I need that in phase 2, they will be authenticated through a radius server.
Is there a way to configure both user authentication remote vpn?
For example.
All users will be authenticated locally unless the service member COMPUTER that is authenticated by the radius to the testing server.
I have remote vpn users anywhere in the world if I don't want these users are blocked by the radius authentication test. What I want is that users in Group1 will be authenticated locally on the SAA and users in group2 will be authenticated by the RADIUS. During the test will be done, all users will gradually transfer for radius authentication.
Is it possible
Thank you
Jonathan
Network administrator
Hi Jonathan,.
The best way to go about this would be that you set up another group strategy & corresponding tunnel group named Test and set up Radius Authentication for VPN group using the link below: -.
Ones you have done test and feel confident, you can change the type of authentication for the Production Group. The reverse could be implemented double authentication as RADIUS and if it does not use local but personally I'll put up a group of test and then those I am confident, that I'll change the strategy of Production Group to use the Radius Server to auth.

ASA 5510 VPN multiple tunnels through different interfaces
Is it possible to create VPN tunnels on more than one interface to an ASA (specifically 5510 with 8.4), or I'm doing the impossible?
We have 2 public interfaces on our ASA connected to 2 different suppliers.
We must work L2L tunnels of the SAA for remote offices through the interface that is our ISP 'primary' and also used as our default gateway for internet traffic.
We are trying to install a remote office use our secondary connection for its tunnel (office of high traffic we would prefer separate away from the rest of our internet and VPN traffic).
I can create the tunnel with the ACL appropriate for traffic tunnel, card crypto, etc., put in place a static route to force ASA to use the secondary interface for traffic destined for the public of the remote gateway IP address, and when I finished, traffic initiated by the remote site will cause the tunnel to negotiate and find - I can see the tunnel in Show crypto ikev1 his as L2L answering machine MM_ACTIVE , Show ipsec his with the right destination and correct traffic local or remote identities for interesting, but the ASA local never tries to send traffic through the tunnel. If I use tracers of package, it never shows a VPN that is involved in the trafficking of the headquarters in the remote desktop, as if the SAA is not seeing this as for the corresponding VPN tunnel traffic.
If I take the exact same access and crypo card statements list and change them to use the primary ISP connection (and, of course, change the remote desktop IP connects to), then the connection works as expected.
What Miss me?
Here is a sample of the VPN configuration: (PUBLIC_B is our second ISP link, 192.168.0.0/23 is MainOffice 192.168.3.0/24 is FieldOffice)
permit access list range 192.168.0.0 PUBLIC_B_map 255.255.254.0 192.168.3.0 255.255.255.0
NAT (Inside, PUBLIC_B) static source MainOffice MainOffice static FieldOffice FieldOffice
card crypto PUBLIC_B_map 10 corresponds to the address PUBLIC_B_map
card crypto PUBLIC_B_map 10 set counterpart x.x.x.x
card crypto PUBLIC_B_map 10 set transform-set ESP-3DES-SHA ikev1
PUBLIC_B_map PUBLIC_B crypto map interface
tunnel-group x.x.x.x type ipsec-l2l
tunnel-group ipsec-attributes x.x.x.x
IKEv1 pre-shared-key *.
Route PUBLIC_B x.x.x.32 255.255.255.224 y.y.y.y 1
If I take this same exact configuration and change it to use PUBLIC (our primary connection) instead of PUBLIC_B, remove the instruction PUBLIC_B route and change the desktop to point to the ip address of the PUBLIC, then everything works, so my access list and crypto map statements must be correct.
What I don't understand is why the ASA Head Office does not seem to recognize interesting for the tunnel traffic when the tunnel is for the second ISP connection, but works when it is intended for the main ISP. There is no problem of connectivity with the ISP Internet B - as mentioned previously, the tunnel will come and negotiate properly when traffic is started from the desktop, but the traffic of main office is never sent to the bottom of the tunnel - it's as if the ASA does not think that traffic of 192.168.0.x to 192.168.3.x should pass through the VPN.
Any ideas?
Hello
I think your problem is that there is no route for the actual remote network behind the VPN L2L through ISP B connection
You could try adding add the following configuration
card crypto PUBLIC_B_map 10 the value reverse-road
This should automatically add a static route for all remote networks that are configured in the ACL Crypto, through the interface/link-ISP B.
If this does not work, you can try to manually add a static route to the ISP B link/interface for all remote networks VPN L2L in question, and then try again.
The route to the remote VPN peer through the ISP B does not to my knowledge.
I would like to know if it works for you.
It may be useful

Hello
Seems to me that his dynamic State PAT shot meant for Internet traffic
Phase: 6
Type: NAT
Subtype:
Result: ALLOW
Config:
NAT (inside) 1 0.0.0.0 0.0.0.0
is the intellectual property inside everything outside of any
dynamic translation of hen 1 (WAN. IP. ADDR.162 [Interface PAT])
translate_hits = 6186208, untranslate_hits = 145616
Additional information:
Translation dynamic 192.168.21.100/0 to WAN. IP. ADDR.162/12936 using subnet mask 255.255.255.255
So you might miss the NAT0 configuration for this connection
Do the following
Issue the command "Display running nat" and you should see a NAT0 configuration for the 'inside' interface. Something like that
NAT (inside) - 0 access list
Next, you will need to check the ACL configuration
See the list of access running
You can add local and remote network that need to communicate through that VPN L2L connection to this ACL
So for examples sake lets assume that your ASAs directly related "inside" subnet needs to access the remote network, and then you would add
ip 192.168.21.0 access list allow 255.255.255.0 10.50.50.0 255.255.255.0
So use the above configuration format with good source and network of destination, as well as the correct name of the ACL and add the required ACL lines and then try to host LAN connections.
Hope this helps

ASA 5510 - VPN for DMZ with static rule?
I have a 5510 ASA with a number of virtual private networks to other sites, allowing the traffic to and from the Interior of the networks.
I need to establish a VPN rule to another site, but they have very little access to resources on my local network. Because I am not in control of the SAA on this end permanently, I need to control that access on my 5510.
(the following is not my real IP, but I use them for this example)
My network: 10.100.1.x
My DMZ: 192.168.1.x
Internal network of other sites: 172.16.1.x
I wanted to try to create a VPN between the site and the specific address of DMZ on my side and then allow access to internal addresses using static rules. I decided to use a static rule to enable http access to a specific server (for example):
static (inside, dmz) 192.168.1.200 tcp 80 10.100.1.200 80
I need allow traffic here:
access-list permits DMZ_IN tcp host 172.16.1.10 host 192.168.1.200 eq 80
Access-group interface dmz DMZ_IN
And of course, rules of access list which allow traffic that I can apply to the VPN:
toSite host 192.168.1.200 ip access list permit 172.16.1.10
And I don't want that traffic THAT NAT had between my DMZ and the other site:
nonatDMZ of the host 192.168.1.200 ip access list permit 172.16.1.10
NAT (dmz) 0-list of access nonatDMZ
NAT (dmz) 1 0.0.0.0 0.0.0.0
And, of course, the corresponding rules on their ASA must be in place, allowing traffic to 192.168.1.200, not NAT it.
Everything is in place, but 172.16.1.10 to 192.168.1.200 http traffic never reaches 10.100.1.200. I know the following:
1. the VPN is configured correctly. If I add rules allowing traffic to (and from) 172.16.1.10 and 10.100.1.200 directly, they work.
2 packet trace shows me that traffic is allowed.
3. the works of static rule: to access the 192.168.1.200:80 of another host on the same interface, DMZ, which brings me to 10.100.1.200:80
4. in the process of running a sniffer package on 10.100.1.200 shows 172.16.1.10 traffic does not reach it.
So I'm banging my head against the wall here. I'm sure it's something simple I'm missing. Anything else I need to check? Should I go about this a different way?
Thank you.
What you are trying to reach is not supported. You cannot configure NATing between the inside and the demilitarized zone interfaces while your VPN connection is from the external interface. The static NAT (inside the dmz) that you have configured will only work if the connection is initiated from the inside towards the demilitarized zone and vice versa.
I think that what you are trying to reach is only allowing access on TCP/80 to10.100.1.200 for the VPN tunnel.
You must configure your option 1:
1. the VPN is configured correctly. If I add rules allowing traffic to (and from) 172.16.1.10 and 10.100.1.200 directly, they work.
You can configure vpn-filter to limit the traffic to the only TCP/80, and he attributed to group policy that you have assigned to this particular tunnel group then.
Example:
web access list - allow permit tcp host 172.16.1.10 host 10.100.1.200 eq 80
internal group-policy-strategy web
attribute group web-strategy strategy
value of VPN-filter web - allows
global-tunnel-group attributes
Group Policy - by default-web-policy
Here is an example configuration for your reference:
Hope that helps.

R8000 Open VPN drops Internet connection
I have a router R8000 and sometimes when I go to connect by using the open VPN connection that it will show as connected but I don't have any internet access more. My connection log is below. The XXX is corresponding to my external IP address of the router.
I have the service defined on the port UDP 12970 type. Firmware version: V1.0.3.4_1.1.2
Journal will be in the next post, because there is a limit of 20,000 characters.
In fact, I found a way around the problem. If you change the Protocol to TCP UDP everything works fine. Don't know what the problem is with UDP though.

When I connect to the VPN on my laptop from home (using a wireless connection), I can't access the Internet.
Any help?
Hello
Depending on the system and its configuration, it is not always possible to solve this problem.
However, try this.
Make sure that the default route has NOT changed to the VPN server.
Open the properties of your VPN connection.
Go to 'network '. Double click on TCP/IP protocol. Use the button "Advanced".Disable the feature from default gateway.
For the best solution if you are using a cable/DSL router which is also home VPN endpoint you can take the 'Off' the computer VPN.

ASA 5505 <>ASA 5510 VPN Site to Site
Try to configure a vpn site-to site beetween an ASA 5505 and a 5510. I can't get anything thrown, there are now debugging messages or the other. I must have done something wrong, I followed this paper: http://www.cisco.com/en/US/products/ps6120/products_configuration_example09186a0080950890.shtml but I can't make it work. Anyone can have a peek at my configs, maybe I forgot something.
OK, if you go ahead and add this command to all two firewalls 'inside access management' and try to one side inside the 10.21.32.10 ping always nothing passing by?

Right answers. 'administrator' is not a valid dn connection in an ldap infrastructure. Follow what srue said and that will lead you in the right direction.

Hi Javi,
Please after the release of "see broadcasting DfltGrpPolicy of any political group." See if you have the "vpn-idle-timoeout" command configured in that. If so, please change to "vpn-idle-timeout no" and see if that stops at these popping up error messages.

Cisco's ASA 5510 VPN configuration suggestion
Hello
We have a cisco ASA5510 and our client has a device of Juniper. We already have a vpn tunnel between two locations and its working fine.
Now they have networks that are in a safer area, if we add these subnets of the current tunnel we are not able to access it.
so, what they suggest we can reconfigure the VPN to be a road based on VPN instead of policy based OR configure a second VPN tunnel.
not sure about cisco ASA supports route according to the tunnels? ... Can we create a 2nd tunnel between the same devices (asa5510 and thei Juniper device) as remainders IP that identical, only the internal remote networks will change for me. is this possible?
do I have to make changes to the current tunnel?
Thank you
Smail
Hello
Cisco ASA does not support database path tunnels.
You must add new networks to crypto ACL. They add new VPN policies.
