VPN – Ports

L2TP uses UDP 1701.

For IPSEC to pass through your firewall you will need two things:

1. UDP 500 open for ISAKMP. This will allow the key negotiation to take place between the two IPSec

endpoints.

2. The firewall must recognize IPSec traffic. IPSec is an IP based protocol like UDP, TCP, ICMP,

OSPF, GRE, etc. Seems to me that they are IP protocol types 50 (ESP) and 51 (AH). Your firewall must

be able to recognize and/or filter ip types (not tcp/udp ports).

XXCOPY – Backup Your Hard Disk

USING XXCOPY TO CLONE\BACKUP

A good way to back-up your system is to get a second hard disk of the same or greater capacity, and use the

free XXCopy from http://www.xxcopy.com/

to make a clone of your system. If the BIOS allows it, you can

then set the BIOS to boot to the alternative drive to run the cloned system, format the drive containing the

defective system, clone the cloned system back to the main drive, set the BIOS to boot from the main drive,

and you are back in business. You can keep the spare hard disk drive stored in a safe place ready to be

reinstalled in an emergency, or to update the cloned system.

You install XXCopy according to the instructions that come with it. To clone the C: drive to a D: drive

enter the following command in the Start => Run box

xxcopy c:\*.* d:\ /clone

It is as simple as that XXCopy will open a DOS window and clone the c: drive to the other drive specified

in the command.
