IPSec over TCP works on VPN 3030 interface (3) external?
I configured the third external interface and can connect with the ESP and UDP tunnel, but not with IPsec over TCP.
The customer says:
Unexpected TCP control packet received a.b.c.d, src port 10000, port dst 4408, flags 14: 00
the hub said nothing, although I tried several event classes
the document said "IPSec over TCP works with the VPN client software and hardware VPN 3002 client. It only works on the public interface. It is a client to the function of hub only. It does not work for LAN-to-LAN connections. "
This means - it works on the public interface real, physical?
or it should work on the external interface if I click on the checkbox to its public interface?
Thanks for any advice,
Martin
IPSec over TCP is designed to operate only on the real public interface #2.
There were a few technical reasons behind it, among them:
(1) some clients cancel their tunnels on the private interface (one-arm-config) and that would cause a headache when trying to HTTP through the VPN 3000 if IPSec/TCP has been installed for Port 80/443. We decided to pull out of the private Interface.
(2) that the external interface #3, we have chosen not to enable IPSec/over TCP Dynamics fielterso n it mainly because of the load balancing.
Since the LB only works on real public interface #2, even once, we chose to leave
IPSec/TCP out of it.

Nice day
I would like to know if there is the possibility of configuring IPSEC over TCP on the pix Firewall.
This features are supported by the latest Pix OS (6.3.3)?
Thank you
Diego
The pix does not support ipsec over tcp. It supports NAT Traversal that is ipsec over udp. IPSEC over tcp is compatible with the VPN concentrator. The next link talks about NAT traversal.

Difference between IPSec over TCP and UDP IPsecover
Hello world
I'm testing the VPN to the user's PC.
When I test the PC of the user using IPsecoverTCP it uses protocol 10000.
When I check on ASA - ASDM under connection details
ike1 - UDP Destination Port 500
IPsecOverTCP TCP Dst Port 10000
using Ipsecover UDP
IKEv1 - Destination UDP 500 Port
IPsecOverUDP - Port of Destination UDP Tunnel 10000
Therefore when using TCP or UDP uses the same port 500 and 10000.
Is need to know what is the major difference between these two connections just TCP or UDP?
Concerning
MAhesh
IPSec over TCP is used in scenarios where:
1 UDP port 500 is blocked, resulting in incomplete IKE negotiations
2 ESP is not allowed to cross and encrypted traffic thus do not cross.
3. network administrator prefers to use a connection oriented protocol.
4. IPSec over TCP may be necessary when the intermediate NAT or PAT device is stateful firewall.
As there are IPSec over UDP with IPSec over TCP, there is no room for negotiation. IPSec on the TCP packets are encapsulated from the beginning of the cycle of implementation of the tunnel. This feature is available only for remote access VPN not for tunnel L2L. Also does not work with proxy firewall.
While IPSec via UDP, similar to NAT - T, is used to encapsulate ESP packets using a UDP wrapper. Useful in scenarios where the VPN clients don't support NAT - T and are behind a firewall that does not allow the ESP packets to pass through. IN IPSec over UDP, the IKE negotiations has always use port UDP 500.

When you set this option on the SAA, that affect all VPN? It is an element of configuration global, if I work with UDP VPN, but I am to set up a VPN using TCP, the other VPN still use UDP, or that they do not fail as the other end isn't the same configuration?
IPSec over TCP is supported only for the connection to access remote vpn client for the SAA. It is not supported for VPN LAN-to-LAN tunnel.
And Yes, it will affect all the client connection to access remote vpn for the SAA once you activate it in the world.

IPSec over TCP on PIX 501F to the catalog
Hello
Is there a way I can configure IPSec over TCP as default configuration in the PIX firewall. I'm under 6.3
The PIX does not support IPsec over TCP. It doesn't support NAT - T, which is IPSec over UDP/4500, which houses also of the Cisco VPN client. Just add the following command on the PIX:
ISAKMP nat-traversal
The PIX and VPN client auto-négociera if necessary IPSec encapsulation. See http://www.cisco.com/univercd/cc/td/doc/product/iaabu/pix/pix_sw/v_63/cmdref/gl.htm#wp1027312 for more details.

3.5.1 to 506th Pix VPN Client using IPsec over TCP
Is it possible to do when there is a device in the path of the VPN tunnel that will make the static NAT?
The reason is that the external interface of the Pix will have a private address, and it is the endpoint of the tunnel. The performance of NAT device has a public address, who thinks that the VPN client is the end of the tunnel, the static NAT will result the incoming packets on port UDP 500 for a destination of the Pix.
Thank you.
The Pix can not do TCP encapsulation. He can do UDP encapsulation.
You can create IPSec tunnels to the external of the Pix even if address he addresses NATted provided that it is NOT of PAT and NAT.

IPsec over UDP - remote VPN access
Hello world
The VPN client user PC IPSEC over UDP option is checked under transport.
When I check the details of the phase 1 of IKE ASDM of user login, it shows only UDP 500 port not port 4500.
Means that user PC VPN ASA there that no device in question makes NAT.
What happens if we checked the same option in the client IPSEC VPN - over UDP and now, if we see the port UDP 4500 under IKE phase 1 Connection Details
This means that there is now ASA a NAT device VPN Client PC, but he allows IKE connection phase 1?
Concerning
MAhesh
Hello Manu,
I suggest to use the following commands on your ASA have a look at these ports as the test of VPN connections. The command that you use depends on your level of software as minor changes in the format of the command
View details remote vpn-sessiondb
view sessiondb-vpn remote detail filter p-ipaddress
Or
View details of ra-ikev1-ipsec-vpn-sessiondb
display the filter retail ra-ikev1-ipsec-vpn-sessiondb p-ipaddress
These will provide information on the type of VPN Client connection.
Here are a few out of different situations when connecting with the VPN Client
Dynamic PAT - no Transparent on the Client VPN tunnel
- Through the VPN connections do not work as connects via PAT without Transparent tunnel

Above are examples for your reference. I must also say that I am absolutely not an expert when it comes to virtual private networks in general. I had to learn two firewall/vpn basically on my own, as during my studies, we had no classes related to them (which was quite strange).
While I learned how to set up VPN and troubleshoot them I think I missed on the basic theory. I had plans to get the title Associates CCNA/CCNP certifications but at the moment everything is possible. Don't have the time for it.
I guess that you already go to the VPN security CCNP Exam?
Hope this helps and I hope that I didn't get anything wrong above

I realize that it is a long title. It could be useful describe my problem.
Recently, I downloaded something (not sure if I can't talk about website) and with download received 4 bad files found by Malwarebytes named: PUP. OfferBundle and PUP. ToolbarDownload. These 4 files were quarantined and then removed, but this does not solve my problem. I ran Microsoft and other spyware, but nothing more has been discovered.
I have Norton Internet Security, which extends constantly and I always have these terrible files.
I can not access Google search engine. I get this message: error 404 (not FOUND)! 1

Impossible to get WebVPN working on chassis VPN 3030
This v4.1.7P chassis works perfectly for our installation of the client vpn Cisco, no problem. We have decided to extend its usefulness by turning on and configuring WebVPN.
I did it on a router IOS, Cisco 1841, works very well, so I'm following the same basic procedure to activate it on our vpn 3030.
But when trying to connect to the vpn 3030 to the public interface of an internet ISP, I even don't get a login window, error, same no nothing. Finally the browser times out and stops.
I did all the usual steps to enable WebVPN, yet nothing seems to work. I can't admin the box fine internally via https, so I know that work self-signed certificates.
Any ideas where the attack of this of?
Thanks, Jeff
Hi Jeff,
Try to upgrade to 4.7.x

Hi all
Asked me to configure the load balancing between two hub Cisco VPN (Cisco VPN 3030).
I set up two such boxes mentioned in the cisco Web site
[url] https://www.Cisco.com/en/us/products/HW/vpndevc/ps2284/products_tech_note09186a0080094b4a.shtml [url]
After you enable VPN load balancing, I get the error described for 30 seconds.
Quote:
Master double detected LBSSF [0003a 0889463] and going to SLAVE
One of my friends said me that try with encryption active but not different.
I searched in google but did not get any solution. I am now hlepless. If any of you guys have met this kind of problem before could you please help to solve this problem...
Thank you
Please set each device to have different priorities and then charge two devices.
If this does not work then you can confirm your settings of the VCA have been properly configured and applied to the public interface? The following links provide more details on how to configure filters VCA:

Using TCP on the second ethernet interface
Hello
I use a PXI 8109 Pharlap module running.
I try to use the second my PXI ethernet interface to send UDP and TCP packets. The main interface is used to manage channels Veristand.
Here is the configuration of my two ethernet interfaces:
-eth0 (primary):
IP: 10.0.0.3
subnet mask: 255.0.0.0
-eth1:
IP: 192.168.10.9
subnet mask: 255.255.255.0
For UDP, I have no problem, the packets are sent to the second interface as I want to. I think it works because there is an entry "network address" on the "Open UDP" VI so that the system can choose the right interface.
For TCP, I use the VI "to open a TCP connection" but there is not that kind of entry. And it does not work: I suppose that the system tries to use the main interface, but it can route packets...
For more information, my two networks is physically independent.
Can you help me find out what is happening? Is it possible to use the TCP protocol on the second ethernet interface?
Thank you very much
Kind regards
