How can I get RPC over HTTPS to work initially from outside a watchguard firewall? I have configured Outlook Anywhere on a WIndows 2003/Exchange 2007 server. Outlook anywhere works fine if it is initially configured on the private side of the firewall but I am unable to connect "new" clients from outside the firewall. Once a connection is started the firewall blocks the IP and thats all she wrote. It will however work perfectly if the client connecting from outside was initially connected and configured inside the firewall.
