Can't figure out this one? Am I overlooking something way basic?
To allow server (W32Time service) to synchronize time with external SNTP
server (the famous tock.usno.navy.mil at 192.5.41.41) I have set up the
following IP Packet Filter:
------------------------------
Filter Type:
IP Protocol: UDP
Direction: Send receive
Local port: All ports
Remote port: Fixed port
Remote port number: 123
This computer:
This ISA server's external IP address: wwww.xxx.yyy.zzz
Remote computer:
This remote computer: 192.5.41.41
------------------------------
Then in the Firewall logs I see the packets to UDP port 123 blocked:
Date: 2002-09-30
Time: 02:44:20
Source-ip: wwww.xxx.yyy.zzz
Destination-ip: 192.5.41.41
Protocol: Udp
Param#1: 50111
Param#2 123
Filter rule: BLOCKED
Interface: wwww.xxx.yyy.zzz
Why is it blocking them???
