VPN connected, stream out of VPN tunnel
I mean that we have in place of the VPN Sites manage to sites with 2 RV042 router but it seams not as I wanted. Are you sure that each transfer of data through Router 2 will go into the VPN tunnel or it shuts down the VPN tunnel. I checked the routing table and saw that:
Sources mask Gateway Interface
2 1 or wan wan IP 255.255.255.0 ipsec0 private
By default 0.0.0.0 (ip wan 1 or 2) wan1 or wan2
.........
So what you think what sense data will pass through the line, it will go through the ipsec section or through wan1 or wan2. Ofcouse each data will pass through wan1 or wan2, but it can go inside the ipsec tunnel or ipsec outside tunnel. If she goes inside the ipsec tunnel, everything is ok, but if this isn't the case, transfer of unsecured data. I'm trying to access some website is not in private ip and it was outside ipsec tunnel go, I can capture and now that you have access.
Why with linksys have 2 work as draytek product even photos follow:
Can someone help me to answer this question, thank you for your attention
1. it depends on what the tunnels of your business allows. As I've written before, there are other protocols that allows you to route traffic through the VPN tunnel. Only IPSec cannot do this. For example, if your company uses GRE over IPSec then they can route traffic through their tunnels. Your RV does not support this.
2. If it's really plain IPSec then you cannot configure several subnets. You can try to implement the security group remote as a subnet more grand, such as 10.0.0.0/8. Of course the groups must match on both sides.
3. If you want to route all traffic through the tunnel, and then try to set the local/remote security to 0.0.0.0/0.0.0.0 group. Maybe it works.
The configuration of IPSec in the RV042 does not allow extremely complex configurations. It's mainly to connect two subnets between them.

Connectivity on the VPN tunnel problem.
Hello
I have a site to tunnel between the PIX506 and Cisco VPN 3000 Concentrator. I'll be spending it again ASA5510, so the tunnel will be established between the ASA and PIX. After inistial tests, I found only one box of remote network (time clock lol) is down by connectivity while tunnel between Pix and ASA (works fine with the hub). All traffic is allowed through the VPN tunnel built on SAA is? I understand it should be as long as the tunnel is running, correct? (Note: the remote clock uses ports TCP 8888 and 8889 to communicate with the server)
Thank you
If there is no filter, again all traffic should be allowed.
You need not choose L2TP connection is pure IPsec.
If you wish, you can post your configurations to check them out (you can remove sensitive information)

VPN tunnel via PPPoE connection
The remote site uses a PPPoE DSL connection on a wic etihernet. We have the work of setting up PPPoE, but we are unable to establish the VPN tunnel. When the tunnel is activated, since the PIX debugging logs show the following:

I tried setting the IP MTU size to 1492 and 1500 on the interface of the router Dialer but I still get the same case. You have any ideas or places to look. We are able to establish a VPN tunnel from this location with a Linksys VPN router or router Drakor. This same router also works when you are using a DSL connection, requiring no PPPoE.
Thank you
JUan
Remove this line on the router:
IP nat inside source list Dialer1 160 interface overload
because this would cause the NAT router all encrypted packets which you don't want. On the PIX, you must change this:
NAT (inside) 0-list of access splittunnel
to reference the ACL sheep or add the 192.168.50.0 subnet in the ACL splittunnel.
On the PIX, enter in the following (I know they are there already):
Outside 1500 MTU
Within 1500 MTU
MTU 1500 dmz
then save the config and rebooting, it must get rid of the MTU messages.

2 VPN tunnels between 2 devices on separate links
Hello
I have a 2811 connected to two different ISPS, which means I have 2 separate interfaces for the two links. Initially, I set up a VPN tunnel to a 3rd party remote site on one of the links/interfaces. I'm now required to configure a VPN tunnel to additional on the same remote site on the other interface/link. When I finished the config and run tests, I get an error saying that the card encryption does not apply on the correct interface and that the peer is routed through a non-crypto map interface.
One thing I would like to know is if it is possible to configure the router to establish these two tunnels on the different links and interfaces of the same peer. Please note that the first VPN tunnel is still active, but the other comes to refuse to come. Please see excerpts of my router config below:

Therefore the tunnel running on isps1 it's very good, while the tunnel on ISP2 does not come to the top.
While this sticky if I realized that there is no default route to ISP2, this could be the problem and adding another default route would not create a sort of loop?
Kind regards
Femi
Femi,
You don't need to put the two ISPs in the VRF, Anthony I'm not seeing something it does not require in your case.
But anways for config ipsec check the Nico cheat sheet:
https://supportforums.Cisco.com/docs/doc-13524
Special attention around bunch of keys.
You will notice that bunch of keys is defined by prior VRF.
Note also that "FFS" set out in isakmp profile shows where are the clear text packets, generally it should be the same VRF as your LAN interface.
HTH,
Marcin

Site to site VPN tunnel - cannot ping the second interface of the firewall peer inside2
I have two ASA 5505 firewall each with a basic license: FWa and FWb. currently there is a VPN tunnel between them work. I added a second (inside2) interface to the firewall, FWb, but I can't ping firewall FWa, so that I can ping the inside interface of FWa.
I can ping the FWb inside interface 192.168.20.1 from the FWa inside 172.16.1.1 interface, but I can not ping to the 10.52.100.10 of the FWa FWb inside2 interface. I can not ping the gateway host FWa 10.52.100.1.

Hi odelaporte2,
Is very probably the "access management" command is not applied in the second inside, only inside primary (see the race management) which will confirm.
This command can be applied to an interface at a time, for example, if the law is now applied to the inside, it can not be applied to the inside2 at the same time.
It may be useful

Unable to pass traffic between ASA Site to Site VPN Tunnel
Hello
I have problems passing traffic between two ASA firewall. The VPN tunnel is up with a dynamic IP and static IP address. I have attached a diagram of the VPN connection. I'm not sure where the problem lies and what to check next. I think I have all the roads and in the access lists are needed.
I've also attached the ASA5505 config and the ASA5510.
This is the first time that I've set up a VPN connection any guidance would be greatly appreciated.
Thank you
Adam
Hello
Regarding your opinion of configuration Remote Site ASA that you have not added the internal networks of the Central Site VPN L2L configurations at all so the traffic does not pass through the VPN.
access-list outside_1_cryptomap extended permit ip 10.1.1.0 255.255.255.128 10.182.226.0 255.255.*.* access-list exempt extended permit ip 10.1.1.0 255.255.255.128 10.182.226.0 255.255.*.* access-list exempt extended permit ip 10.1.1.0 255.255.255.128 10.182.0.0 255.255.*.* access-list exempt extended permit ip 10.1.1.0 255.255.255.128 192.168.170.0 255.255.*.* access-list exempt extended permit ip 10.1.1.0 255.255.255.128 192.168.172.0 255.255.*.* access-list exempt extended permit ip 10.1.1.0 255.255.255.128 140.15.0.0 255.255.*.*
Take a look at ACL configurations above. The 'exempt' ACL is used in configurations NAT0 and tells the ASA what traffic of exempting from NAT. "outside_1_cryptomap" ACL is used to tell the traffic between the subnets should be using the L2L VPN connection.
So in short on the Remote Site ASA these ACLs should be identical. Make additions to the LIST of VPN L2L, then try again.
I would also like to point out that to ensure that the Central ASAs L2L VPN ACL Site contains the same networks. The ACL on the Central Site will, of course, its internal subnets as the source and the site LAN remote destination.
THW out of ' crypto ipsec to show his " shows you that only the SA between binding Site Central network and the Remote Site LAN was established. Others have not formed as the configuration is lacking at LEAST on the Remote Site ASA. Can also be the Central Site.

Authentication of ACS in the VPN tunnel
We want to enable the ACS authentication to connect to different routers (Cisco 881 s) we have obtained who are communicating with our WAN via VPN tunnels. We want to avoid using public IP of the router to communicate and pass information to user/password with the ACS server and rely on the IP of the server private instead. The problem is that external interfaces of the router connect to the Internet using public IP addresses and when the router wishes to communicate with the ACS server it will use its IP of the interface to the public and which will fail. We can ping on the server of course when we set the source to the internal LAN IP.
The question is are there any way to have the router contact ACS through the VPN tunnel using a private IP address?
config is used and tested with success on local equipment:
AAA new-model
RADIUS-server host 10.x.x.x single-connection key xxxxxx
AAA authentication login Ganymede-local group local Ganymede
AAA authorization commands x Ganymede-local group Ganymede + if authenticated
AAA authorization exec Ganymede-local group Ganymede + authenticated if
See the establishment of privileges exec level x
line vty 0 4
Ganymede-local authentication login
authorization controls Ganymede-local x
-ACS ping to the router (WAN via VPN connection) when using public IP address of the router as the source address:
RT881 #ping 10.x.x.x
Type to abort escape sequence.
Send 5, echoes ICMP 100 bytes to 10.x.x.x, time-out is 2 seconds:
.....
Success rate is 0% (0/5)
-ACS ping to the router (WAN via VPN connection) when using IP private of the LAN as source address:
RT881 #ping source 10.x.x.1 10.x.x.x
Type to abort escape sequence.
Send 5, echoes ICMP 100 bytes to 10.x.x.x, time-out is 2 seconds:
Packet sent with a source address of 10.x.x.1
!!!!!
Success rate is 100 per cent (5/5), round-trip min/avg/max = 72/72/76 ms
Looking forward to your responses and suggestions.
Thanks, M.
Hey Maher,
You can use the command 'Ganymede-source interface ip' or 'RADIUS source-interface ip' for your scenario.
I hope this helps!

IPSEC VPN tunnel on issue of Zonebased Firewall
Help, please!
I'm trying to configure a router lab ISR1921 to build the VPN tunnel with vmware vshield edge. The configuration of the 1921 is pasted below. There is not a lot of adjustment on the side of vshield really and I'm sure both sides are adapting to phase 1 & 2.
The question I have: the tunnel can be built correctly and I also see from show crypto ipsec release encap and decap counters. However the devices on each side can communicate. That said, I can ping from 1921 to the IP of the internal interface of the vshield with IP source specified. But just no communication part and other...
I did debugs and only "error" messages are:
01:58:03.193 20 February: ISAKMP: (1001): error suppression node 1656104565 FALSE reason 'informational (in) State d1.
...
01:58:03.193 20 February: ISAKMP: (1001): purge the node-1657220080
I hope that I did a stupid thing to configure error, but I spent too much time on it. It is supposed to be a really simple installation... Please help!

NAT looks fine.
Please create an ACL with bidirecctional ACEs and add it as a group of access to the interface of penetration:
IP access-list extended 180
IP 192.168.100.0 allow 0.0.0.255 192.168.1.0 0.0.0.255 connect
ip permit 192.168.1.0 0.0.0.255 192.168.100.0 0.0.0.255 connect
allow an ip
interface GigabitEthernet0/1
IP access-group 180 to
IP access-group out 180
Generer generate traffic, then run the command display 180 access lists .
Also, if possible activate debug ip icmp at the same time.
Share the results.
Thank you

How to get specific IP through VPN tunnel
I've implemented remote access via VPN Cisco VPN.
We use the tunneling split at the tunel internal IP of VPN tunnel only range.
Now I need to get a specific IP address on the Cisco VPN Client
through Internet and internal network.
I added this specific IP address to split tunnel ACL
I can check it out using Cisco VPN Client, status > statistics, details of the itinerary.
but when I traceroute to that specific IP address it ends on
first jump, ASA public interface.
ASA road 0.0.0.0/0.
I need to put in place?Hello
If you need to allow the VPN client to connect to the ASA and you--turn to the Internet, you must:
permit same-security-traffic intra-interface
Also, make sure you NAT traffic:
NAT (outside) 1 VPN-range
Global 1 interface (outside)
Be careful with the above NAT commands (is just one example and depends on your configuration).

Interpret what is allowed on the VPN tunnel
Hello
I work with Cisco PIX equipment for the first time and I'm trying to understand what is allowed on one of the VPN tunnels which are established on the PIX.
I interpret this PIX did by reading the running configuration. I was able to understand most of it (with the help of the cisco site), so I'm starting to get comfortable with it. I'm looking for more help in the interpretation of what is allowed by a good VPN tunnel. Here are some details:
map Cyril 2 ipsec-isakmp crypto
Cyril 2 crypto card matches the acl-vpntalk address
access list acl-vpntalk allowed ip object-group my_inside_network 172.17.144.0 255.255.255.0
So, if I interpret it correctly, then the traffic matching ACL acl-vpntalk will go on the VPN tunnel.
As far as the lists others access dedicated, my inner interface I have:
Access-group acl-Interior interface inside
With ACL-Interior:
access list acl-Interior ip allow a whole
So nothing complicated there.
Now, just because of all this I conclude I encouraged all remote network traffic in my site. If all traffic 172.17.144.0/24 is allowed to join my network.
However, I don't know if this conclusion is correct.
This ACL is also applied:
Access-group acl-outside in external interface
And it looks like:
deny access list acl-outside ip a
I'm not sure if this ACL applies to vehicles coming from the IPSEC peer. It's for sure inbound on the external interface, but if it is valid for the IPSEC traffic I don't know.
If it is valid, then am I had reason to conclude that only connections initiated from my inside network to the remote control can come back?
Thanks in advance for your ideas.
With sincere friendships.
Kevin
Hey Kevin,
Here are my comments, hope you find them useful:
1. the ACL called "acl-vpntalk" sets traffic who will visit the IPSec tunnel, so you got that right. All traffic from the group called "my_inside_network" will 172.17.144.0/24 will pass through the tunnel, and there should be a similar to the other VPN end opposite ACL.
2. the 'acl-inside' applied to the inside interface allows any ip traffic coming out of the isnide to any destination.
3. the 'acl-outside' rejects all traffic from entering your home network, but the IPSec traffic is free and will cross because you will find a "sysopt connection permit-ipsec' configured on your PIX command that tells the operating system to allow all traffic destined for VPN tunnels without explicitly enabling it through the inbound ACL. If you have stopped the "sysopt" should stop your traffic and you will have more control on your tunnel traffic.
Personally, I usually disable the "sysopt" and control the VPN traffic in my incoming ACL.
Just a quick note, if you look more deeply into the ACL on the PIX functionality, you will find that no traffic moves inside, if she is not allowed on the external interface. For example, you can allow traffic between "inside" and "dmz" interfaces by adding an entry 'allow' on one of the ACLS applied to one of these interfaces. But when you want to allow traffic from the external interface (security level 0), you will need to allow in the inbound ACL applied on the external interface.
I could have written something vague, but I hope you get my point.
Thank you.
Salem.

Site to Site VPN tunnel between two ASA
I use the Site Wizard to Site on an ASA 5520, and ASA 5505 of the ADSM. Both are using 8.4 (5). When you create configurations. You follow the wizard configurations with manual what ACL s to allow the traffic of every subnet connected to talk to each other? Or they are automatically generated in the configuration file? Have not been to school yet to understand how to create the CLI VPN tunnels and what to look for.
Thank you
Carlos
Hello
First, I would like to say that I don't personally use ASDM for the configuration.
But you should be able to configure all the necessary elements for a connection VPN L2L base through the wizard.
I guess that typical problems to do so could relate to the lack of configuration NAT exempt or might not choose the setting "Bypass Interface Access List" that would mean you would allow traffic from the remote site in the 'external' ACL of ASA local interface. Like all other traffic coming from behind the 'outer' interface
If you share format CLI configurations and say what networks must be able to connect via VPN L2L then I could give the required CLI format configurations.

I was wondering if there is a way to allow only one side of a vpn tunnel to create connections?
Example I have a vpn tunnel going to a site with servers that I manage. I want to be able to get on the servers (via rdp, ssh, etc.) and allow the return of traffic but I don't want the servers to be able to reach me (via rdp, ssh, etc.).
Any ideas?
I use a cisco ASA5540
Hello
You have alteast 2 possibilities
- You can configure a filter ACL on the L2L VPN connection VPN
- Long-term a solution a little messier. Mainly due to the ACL filter of VPN L2L having a slightly different configuration than the usual ACL interface format
- You can turn off (if not already disabled) feature that allows to bypass your 'outer' interface ACL all traffic entering from a VPN connection. In this way, you can control incoming VPN L2L with ACL 'outside' interface traffic.
- connections are allowed as any other Internet connection in the "outside" interface ACL if its fairly simple to manage.
If this is something you are looking for I can tell you how to get to one of them.

ISPS double and two redundant ASA 5520 VPN tunnels
Hi all
I have a requirement that looks like this:
-with two ISPs (of course public IP of different subnets), I have two firewalls that we have to do 2 l2l VPN tunnels.
Virtual private networks will be redundant to each other and in the case where one of the links is congested, traffic should pass through the other tunnel.
Did someone do something like that?
Thank you
Vlad
Hi Vlad,
To have redundant connections, I suggest the following link:
ASA/PIX 7.x: example of redundant Configuration or backup ISP links
To find out when the link is congested? I don't think it could be possible at all on the SAA, with a UDP IP SLA jitter, but I think that it is supported only on IOS routers.
Analysis of IP Service levels using the UDP IP SLA jitter operation
Thank you.
Portu.

LRT224 impossible to deal simultaneously with more than one VPN tunnel?
We have configured a client to gateway VPN tunnel group and six in the tunnels of single user gateway on a LRT224. Each unique connection works perfectly using Shrew soft client. But when we try to connect with a second tunnel, the first tunnel disconnects. It seems that the LRT224 cannot process more than one VPN tunnel at the same time? Is there any configuration, that we would have missed?
TLR log seem to indicate that the Shrew Soft customers use all 192.168.30.0 that their IP address instead of a random IP address in this range.
Try to set each Shrew Soft client with a specific IP address in the 192.168.30.1 - 50 rank instead of ' use virtual adapter and address randomly.

I need to establish a vpn connection between my office and a computer over the internet, allowing access to the internal of the outside lan. I have a problem with my router and I am looking for a new.
Can I use x 3500 to establish a pptp vpn tunnel or it can work only as vpn passthrough?
This modem/router supports VPN passthrough for IPSec, PPTP and L2TP only. Try VPN Linksys Gigabit routers like the series of the LRT.
