ipsec Services: Only one usage of each socket address protocol network address port is normally permitted.

I have a servers that would not connect to the Internet, if I ping the gateway it says that:

Destination unreachable.

i found that the IPSec service was not stated. And if I start it it say: Only one usage of each socket address protocol network address port is normally permitted.

i found that there have been some problems after install

After Installing MS08-037 (951746 and 951748)

The solution was to reserved som port in the TCP/IP protocol

Here is the list of ports that we have seen conflicts with services on the machine.

  • 1645-1646 – Used by IAS
  • 1701-1701 – Used by L2TP
  • 1812-1813 – Used by IAS
  • 2883-2883 – Used by AUTD
  • 4500-4500 – Used by IPSEC

For now we are suggesting customers be proactive and modify the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\ReservedPorts
