Web Access stop working

[skyagade]

Initial setup of LS2.0VL had Web Access (from internet) working for desktop and iPhone. Then manually updated firmware (update tab within NAS Nav did not update firmware) to 1.62; I think originally firmware was 1.61. Now Web Access via buffalonas.com no longer connects, nor does my iPhone app.  Have tried changing numerous settings in both NAS and E4200v1; except not sure exactly how port forwarding router setting should be...except if it default port settings worked intially then why would suddenly not?  Anyhwow, any simple suggestions/thoughts, that I am not thinking of, would be greatly appreciated. Thanks.
