Due to security reason, I have disabled the ICMP ping on my PIX. Afterwards, I find that the Exchange server couldn't route my domain users's e-mail to other Exchange server (hosted in other country). I then review the queue in the Exchange and find that the connector to the other Exchange server is not available. According to my memory, it normally use this queue to route my internal e-mail. However, when I enable the icmp ping on PIX, everything work fine after few minutes.<br />
<br />
Two sites are connected through VPN through PIX. In fact, only ICMP is blocked. Other than that, two Exchange could be pinged each other and POP3, SMTP is working fine through the PIX.<br />
<br />
Why does this happen ?<br />

Disable ICMP ping on PIX will disable SMTP Virtual Connector ??

The term "Backup" means the methods and processes involved to copy computer data (system data as well as application data) to media other than the ones where the data originally live (disk, tape, optical, cloud). "Restore" in turn means the methods and processes involved in data recovery, i. e., bringing back copied computer data to their original location. Backup/Restore primarily serves as a means of protection against data loss, be it due to disaster, corruption or sabotage. It can also be used for recovering data from an earlier point in time and even for cloning machines or applications. There is a wide variety of backup/restore software available, from expensive commercial products to free or open source tools.
