I'm assuming you are establishing the VPN from a client PC to a server. If that's the case, I don't think multicast will work over IPSec. I think it has to be done from a routing/router with some sort of GRE Tunnel, etc. through the router-to-router VPN.
This isn't AccessGrid related, but it may help. http://support.microsoft.com/kb/293855 -----Original Message----- From: owner-ag-t...@mcs.anl.gov [mailto:owner-ag-t...@mcs.anl.gov] On Behalf Of Mustafa Varank Sent: Tuesday, January 11, 2005 11:43 AM To: ag-t...@mcs.anl.gov Subject: [AG-TECH] AG over VPN Hello Everybody, Does anybody know how to get AG work over VPN.
