Restricting traffic through a VPN IPsec
I have a lan-to-lan IPsec VPN (PIX501) work, but I would like to limit access to LAN A LAN B I tried to use the command 'no permit-ipsec sysopt connection' with a few changes in the ACCESS LIST bound to the external interface. I did not work. Donkey help would be welcome (doc, experience, etc.).
I think in ACL 101 line 3 must be:
line 3 of the access list 101 permit tcp FAA 255.255.255.0 192.168.0.0 255.255.255.0 eq citrix-ica

An ASA inspect traffic through a VPN?
The ASA did inspect the traffic through a VPN using the default inspect the rules?
Hi Justin,
The SAA can inspect traffic encryption before or after decryption. The ASA cannot inspect encrypted traffic.
This means that if the VPN tunnel ends on the ASA, ASA can inspect traffic sent through the prior encryption tunnel and could inspect the traffic post decryption when received.
If the tunnel is not over on the SAA but pass instead through the ASA, ASA cannot inspect traffic encapsulated inside.
It will be useful.
Federico.

How to send all traffic through the VPN, RV082 material v3
Hello
I found this guide to send all traffic to RV042 branch to the RV082 of central office:
But this guide is for the material of v2. I tried and did not work, so I wonder if there are new modules for hardware v3 (firmware v4.2)
I have a RV042 brach office connected through the VPN Tunnel work to a central office RV082. I want to route all traffic
Office of brach in the RV082 from the central office.
Thank you very much
Oliver
Hi Oliver, this is called esp wildcard forwarding (full tunnel).

Send all traffic through the vpn tunnel
Does anyone know how to send all traffic through the tunnel vpn on both sides? I have a server EZVpn on one side and one EZVpn client on the other. I'm not natting on each side. I use the value default 'tunnelall' for the attributes of group policy. On the client side all traffic, even if not intended for the subnet of the side server, seems to pass through the tunnel. But if I ping the side server, the same rules don't seem to apply. Traffic destined for rates aside customer through the tunnel, but the traffic that is not pumped on the external interface in the clear. That's not cool.
Hello
Clinet traffic to server through tunnel, that's right, right?
Traffic from server to client through tunnel, but the rest of the traffic is not, no?
This works as expected because in ezvpn, politics of "tunnel all ' is for traffic is coming from the client., do not leave the server.
Side server, customer traffic will pass through tunnel, the rest used.

No traffic through the VPN tunnel but at the same time
Hey everybody,
Good enough at the end of my VPN configuration but I have a question. The VPN connection is established and the remote computer can set up a VPN with my router (phases 1 and 2 are ok) but I can't ping all devices on both sides. I think it might be something about the acl. I created an acl that I linked with my group of vpn, what should I do something with the card?

Sylvain,
Let me explain again:
IP nat inside source list 10 interface Dialer1 overload
overload of IP nat inside source list 110 interface Dialer1
Here you are from two ACL, but they are the same with the difference, that NAT 10 110 also but WITHOUT user VPN and everything inside. Problem is that 10 matches first, if the connection will not work. You can disable entry NAT with 10 110 because that will also:
no nat ip inside the source list 10 interface Dialer1 overload
That should be enough.

Problem passing traffic through the VPN tunnel
With well over 150 VPN lan-to-lan tunnels configured, I can usually get tunnels upward. However, this one is stumping me, unless the ISP is to give false information. Using a router Cisco 871 on-site a Cisco 3005 concentrator in my data center, I have set up my tunnel. The tunnel will go up but won't traffic. I am sure that the configurations on both devices are correct because I use a lot of "cut-and - paste." So, the only question seems to be the modem/router provided by your ISP. Usually, when this happens, the problem is with NAT enabled on their equipment. According to them, that it is not enabled on their NAT router. Where can else I check? Any ideas?

Go simple traffic over the VPN tunnel
Hi Pros,
We have a problem with the traffic through the VPN. Specific subnets is not able to reach a specific HOST in the HQ, however, the host in the HQ can reach this subent on the remote database. Interresting to traffic to the vpn are mirrored on the other. Here is the partial config of the remote vpn router.

You really set one of the following routes, and it seems wrong that it should really be directed to the jump to next to the router. It should just route through the default route if you have configured listed routes. PLS, delete them if those are all you have configured and left the default route in the configuration.
IP route 1.0.10.0 255.255.255.0 210.199x.2xx.xx (public IP address of the router vpn HQ)
IP route 4.0.x.0 255.255.255.0 210.199x.2xx.xx

IP route 10.254.254.56 255.255.255.255 210.199x.2xx.xx
Also, if it works in a way, it is more likely an access-list or a firewall that blocks traffic in one direction.

WRT 1900 ACS - Impossible to carry web traffic through openvpn
2.3.11 OpenVPN windows 7 X 86. Router information
Firmware version: 1.0.0.169041 Serial number: 18E1060B503339 By default, OpenVPN only sends traffic over the VPN, which is intended for the VPN. Normal traffic to Web sites, for example, is not sent by the VPN. Which can be modified to send all traffic through the VPN?
Router WRT1900ACS is a SOHO router. It doesn't have a feature of access rule where the web traffic can be managed and regulated. The tool of Parental control of your Linksys Smart Wi - Fi account is designed for local customers only.
Note:
OpenVPN can create the tunnel from the remote host to the main network and thus web traffic cannot be routed through the router firewall.

Hi people
I want to ask you, how to put all of the server the easy vpn client VPN traffic through.
I mean, I have a server vpn at home, and if I connect to the vpn from outside server, to be with an IP address of my home.
There is the configuration up to now. Where is the problem?

To do this you must make the following changes:
(1) disable split Tunneling by deleting the ACL of your configuration of the client group.
(2) enable NAT for VPN traffic by adding 'ip nat inside' to your virtual model of the client network to the ACL that controls your PAT.Edit: Theses are the changes to your config (also with a little cleaning):

Configuration of the router to allow VPN traffic through
I would like to ask for assistance with a specific configuration to allow VPN traffic through a router from 1721.
The network configuration is the following:
Internet - Cisco 1721 - Cisco PIX 506th - LAN
Remote clients connect from the internet by using the Cisco VPN client. The 1721 should just pass the packets through to the PIX, which is 192.168.0.2. Inside of the interface of the router is 192.168.0.1.
The pix was originally configured with a public ip address and has been tested to work well to authenticate VPN connections and passing traffic in the local network. Then, the external ip address was changed to 192.168.0.2 and the router behind.
The 1721 is configured with an ADSL connection, with fall-over automatic for an asynchronous connection. This configuration does not work well, and in the local network, users have normal internet access. I added lists of access for udp, esp and the traffic of the ahp.
Cisco VPN clients receive an error indicating that the remote control is not responding.
I have attached the router for reference, and any help would be greatly apreciated.
Manual.
Brian
For VPN clients reach the PIX to complete their VPN the PIX needs to an address that is accessible from the outside where the customers are. When the PIX was a public address was obviously easy for guests to reach the PIX. When you give the PIX one address private, then he must make a translation. And this becomes a problem if the translation is dynamic.
You have provided a static translation that is what is needed. But you have restricted the TCP 3389. I don't know why you restricted it in this way. What is supposed to happen for ISAKMP and ESP, AHP traffic? How is it to be translated?
If there is not a static translation for ISAKMP traffic, ESP and AHP so clients don't know how to reach the server. Which brings me to the question of what the address is configured in the client to the server?

Split of static traffic between the VPN and NAT
Hi all
We have a VPN from Site to Site that secures all traffic to and from 10.160.8.0/24 to/from 10.0.0.0/8. It's for everything - including Internet traffic. However, there is one exception (of course)...
The part that I can't make it work is if traffic comes from the VPN (10.0.0.0/8) of 10.160.8.5 (on 80 or 443), then the return traffic must go back through the VPN. BUT, if traffic 80 or 443 comes from anywhere else (Internet via X.X.X.X which translates to 10.160.8.5), so there need to be translated réécrirait Internet via Gig2.
I have the following Setup (tried to have just the neccessarry lines)...
interface GigabitEthernet2
address IP Y.Y.Y.Y 255.255.255.0! the X.X.X.X and Y.Y.Y.Y are in the same subnet

With the above configuration, we can get to the Internet 10.160.8.5, but cannot cross it over the VPN tunnel (from 10.200.0.0/16). If I remove the two commands «ip nat inside source static...» ', then the opposite that happens - I can get then to 10.160.8.5 it VPN tunnel but I now can't get to it from the Internet.
How can I get both? It seems that when I hit the first NAT instruction (overload Gig2) that 'decline' in the list of ACL-NAT-outgoing punts me out of this statement of NAT. It can process the following statement of NAT (one of the 'ip nat inside source static... ") but does not seem to"deny"it in the NON - NAT ACL me punt out of this statement of NAT. That's my theory anyway (maybe something is happening?)
If this work like that or I understand something correctly? It's on a router Cisco's Cloud Services (CSR 1000v).
Thank you!
Your netmask is bad for your 10.0.0.0/8. I worry not about the port/protocol or since that can screw you up. A better way to do it would be to deny all IP vpn traffic.

Hello
I am configuring site to site connection using the pre-shared key VPN. The VPN connection is getting up and running, but I'm having problems on information routing between subnets.
Our subnet is 192.168.1.0 and we cannot use that subnet for VPN. Because of this, we use 10.240.86.33 for are created the IPSec traffic and destination network (PC) is on 164.2.107.56.
We cannot connect to the 164.2.107.56 computer network, can someone help us acomplishing this \windows\system32\conifg\system?

It is the router that ends the VPN tunnel? (I don't see the VPN configuration).
Since you can't use your real address LAN, you need to NAT before you send the traffic through the tunnel.
First, you apply the NAT rule to translate 192.168.1.0/24 to 10.240.86.33 when you go to 164.2.107.56
NAT 192.168.1.0 ip access list allow 0.0.0.255 host 164.2.107.56
NAT route map
corresponds to the IP NAT
IP pool local VPNPool 10.240.86.33 10.240.86.33
IP nat inside source overload map route NAT pool VPNPool
Next, you create the ACL list for interesting traffic to address coordinated at the address of the site to another
VPN ip host 10.240.86.33 access list permit 164.2.107.56
We will see the results.

Could someone tell me if and how it is possible to
keep a vpn tunnel open permanently.
Thank you very much
Keith
Hi Keith,
A remote access IPsec tunnel or a tunnel IPsec Site to Site?
Normally, the tunnels were demolished after a period of inactivity (idle) for security reasons.
To keep a tunnel upward, you can keep a constant traffic through the tunnel (so it is never idle and so never back down).
Just out of curiosity, why would keep you the tunnel upward constantly (even if there is no interesting traffic through the tunnel)?

VPN/IPSec-L2L - Question?
Hello!
Recently, I was doing some troubleshooting on a connection VPN/IPSec Lan-to-Lan between a Cisco PIX515E and a Linux firewall. My question concerns the configuration and is not the problem itself.
Traffic interesting (encrypted traffic) defined and configured the LAN of PIX (inside) and the distance public IP? Which means that the Peer IKE and the interesting remote control LAN/IP are the same... and it works!
Any ideas?
Thank you
JP
As long as you source the package from the local network of Pix to remote public IP, the tunnel will work well and works :-)
So, if you really look at the fluidity of the traffic, you're sourcing traffic from Pix LAN intended to public IP remote that corresponds to the defined access list. Thus, the pix knows he has encrypt traffic and now seeks the cryptographic endpoint points (pix outside IP public IP remotely) and sends the encrypted packets. So, this configuration works perfectly.
In fact, Pix will not allow Telnet the external of the pix interface unless the traffic is through an IPSEC Tunnel and it was one of the establishment who gave a telnet access to the external interface of the Pix, it's LAN to the public IP of Pix through an IPSEC Tunnel.
Kind regards
Arul
