Main issue is i need to access outside always when I'm overseas. But Buffalo the "cloud" system is doggy at best and half the time unable to access
or is it due to my network setting issue?
Any advice appreciated...
Direct access to NAS. instead of relying on cloud.
Cloud is convenient but dependable on the bandwidth available by the cloud provider. Usually it is congested
Synology cloud storage is decent but i would still prefer directly connecting to my NAS than adopting the use of cloud.
Just my 2¢ opinion below:
User 'batniss' has already advised you...
When "outside", to connect to your NAS -- use direct access method instead of using cloud method.
IMHO, this is already the most relevant -- one single sentence only -- advise.
DIRECT remote access (method) will usually give you BETTER connection reliability + performance compared to cloud method.
For direct remote access, there are a few connectivity type/options: FTP, WebDAV, VPN (server/client) etc.
No particular type/method of direct access connection is the BEST -- every type of connection has pros & cons.
Some of these direct remote access methods requires (relevant) functions to be supported by your NAS and/or router.
Regardless of whichever type/method of direct remote access connection you use -- it is likely you need to (at least) configure port forwarding at your main router.
(at least search/Google how to do port forwarding for your router model)

IMHO, FTP has higher chances of success for novice / non-network savvy users.
(nowadays, some people prefer to upgrade from FTP to use FTPS for more encryption/security).
Why FTP?
- Almost all NAS -- regardless cheap or expensive NAS -- usually will support FTP (or even FTPS).
- Almost all routers -- regardless cheap or expensive routers -- supports port forwarding.
- For the most basic config to allow FTP to work -- JUST only one (1) single port forwarding (Port: 21) entry is needed to be added in your router.
Whatever device you use when "outside" to access your NAS (Windows/MAC notebook or Android/Apple phone/tablet) -- there are MANY choices of FTP apps/software available (both FREE or paid).
Below is AS SIMPLE AS I CAN SUMMARISE -- for the steps:
(1) Enable/Start FTP service on your NAS + check home network IP address of your NAS.
(2) Set port forwarding in your router -- for Port 21 -- to the home network IP address of your NAS.
(3) Find out the WAN IP address of your Internet connection (too many methods, go search/Google).
(4) Install an FTP app in your phone/tablet/notebook.
Now you can go "outside"...
(5) In the FTP app, add a FTP server by using: your Internet WAN IP address + your NAS user account ID & PW.
(6) Try to connect to this new FTP server you just added in the FTP app; if can access means you've SUCCESSFULLY connected to your home NAS from "outside".
(7) Optional (but highly useful): Because Internet WAN IP for most people changes from time-to-time, some people use FREE DDNS services to map Internet WAN IP to a predefined hostname.
Go search/Google what is DDNS (hint: Dynamic DNS)
