Have you tried port forwarding yet?Here's a comprehensive post which helped me fix it once and for all. Good luck and please report back.. https://portforward.com/help/doublerouterportforwarding.htm
@ZaneP forgot to mention. A simple port forwarding resolved the double NAT issue there are plenty of results to guide through it on Google search (in case a newb reads this).
Time for an update.> NAS 1 : DS920+ : All clear now. I've resolved the access issue which was caused by a double NAT conflict (explaining below).> NAS 2: IX2-200 : Still not accessible but I'll tackle that a bit later.Why double NAT? Well like a psyc...
Thnks @ZaneP, I'm halfway there. Synology NAS can be seen and accessed however not from outside my network which is a bummer since it's my personal cloud. On the other hand my ix2-200's ip is available but can't be accessed. So more fun ahead.
