the logging for snapins is done in the database in the snapinTasks table. this is where snapin tasks are created and when completed the stState is set to 2, stReturnCode tells you if it reported success or failure.
sorry i didn’t make it very clear - this is what i meant, i’m using a port say :25280 but doing an internal rewrite (so u don’t have to specify port in web address) but ALL traffic fitting the pattern for fog gets directed to apache/fog box using the port:25280 and have no issues… with ur port-translation it seems the initial traffic i.e. /fog/ is going to apache but further traffic is not… try looking into apache config, also check logs they will give u a clue with what is wrong and whether apache is seeing the request. like tom said it is environment/routing issues not fog gui, fog gui doesn’t care what port it’s ur apache doing the listening u could test the theory by getting apache to listen on 25280
