Alerting works through the Management Gateway just fine, however, distributing the rulesets is where the challenge arises. When creating a task in the 32-bit console to distribute the ruleset it appears to do a multicast distribution. Through the Gateway pushes will not work so a policy task needs to be performed. What is actually happening with the distribution is an executable called "alertsync.exe" is being called and it performs a "pull" of the ruleset. To put it more simple...you should be able to create a script to call alertsync.exe to download or update the ruleset you want. The script of course will need to be a policy distribution.
Here is a list of parameters for the executable.
C:\Program Files (x86)\LANDesk\LDClient>AlertSync.exe /?
Usage: alertsync [options]
-c port Notify collector
-r URL URL for ruleset to download
-e Erase managed rulesets before download
-f First sync (obtain rulesets from configuration)
-n No redirection
-p Peer only
-b percent Allowed bandwidth
-d dir Ruleset directory
-V level Change verbosity level
Here is the log alertsync from PC

i Still not recive any alerts from PC directly via gateway
In alert log im only see alerts from core.xxxxx.local - core server.
If alertsync.exe is having problems downloading the XML file then the client doesn't have the rulesets yet which would be the next problem to be fixed. The error:
2014-01-20 14:18:00(3240-3244) alertsync.exe:Error downloading rulesets: Error downloadinghttp://CORE.XXXXX.LOCAL/ldlogon/alertrules/ldms.default.ruleset.xml 0x-7279FFEA
The client rulesets (after they are configured) are stored in the directory the error mentions. Distributing files through the Gateway has some requirements but the XML file mentioned isn't required to be on the core as well. You can also store the file on a public web server (or a web server local to the client) and reference the XML file that way. Once the XML is distributed to the client then it can follow the rules outlined in the XML, monitor the system, and alert back to the core.
