IPsec over HTTPS
Is there a way to create an IPSec connection on port 443 (for example if the UDP Port 500 is blocked by outside firewallrules). I noticed some other routers are able, or if it will support on Netgear UTM in futured upgrades?
Thank you...
Never. 500 is integrated with IPSec.
You can use SSL VPN to 443.
You see what routers supporting VPN IPSec on 443?

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.

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.

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.

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.

I download a XML over HTTP. The extension is .php, but it fully contains XML data. The Chrome browser, it shows me - exit iterpreted content defined in XML instead of the Tags etc. However, on IE, I can see XML.
Now in my BlackBerry (curve 8900) application in the connectivity of BIS - B, I get the result interpreted as in Chrome and it of course cannot be parsed.
But if I save the same PHP file (with XML inside) as .xml and do the process above, it works fine - I get XML proper.
Could you please someone indicate why this is happening and how can I solve it?
Well it's rubbish isn't.
Because I assume that your server sends the same data, it appears then that is to be converted by the BIS-B gateway.
You can check all the Http headers you receive to see if you can see a difference. I suspect that the server sends a different Content Type in each case, and the gateway that uses to decide that it can reformat the data.
Otherwise, you might be able to define a header on your application which will stop the bridge BIS-B change the answer. You might find something like those coded in this Thread to work for you.

Taking over Http in Blackberry
Hello
How to reach the socket on the connection Http (SOHT) connection in Blackberry devices?
Help, please
My understanding of this is not an outlet running over an http connection. Who uses an http request to transfer the payload to the device rather than using a power outlet. So, these are some alternative mechanisms, treated differently on the server and the device, not the layers of alternative communication.
A difference between a socket connection and http is connection - socket is continuous, http is not. You will see from here:
http://www.operamini.com/Help/FAQ/#http-socket
If Exchange you it for an http connection, you lose the connection continues. This confirms, as far as I'm concerned, that Opera mini did not use the socket over http.

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.

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

- VPN Client connections to the LAN work because our VPN Client has a static NAT configured for its local IP address. This allows the ESP without encapsulation through the device doing the static NAT. You must allow the ESP traffic through the NAT device of management of the device VPN or configure VPN connections inspection if there is an ASA acting as the NAT device.

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
