Enable Jumbo Frames Causes External Hostname Problem
I use my ReadyNAS to host my web page. If I enable jumbo frames on my NAS and my PC then I can no longer access my web page using my external hostname (dyndns.org address) while on the LAN. I have to ...
Well, its not a naming issue, since you can reach the webserver and it has the same DDNS name.
Are you using https or http to access the NAS? Maybe try both, just to help isolate.
One challenge is that just because jumbo frames are enabled doesn't necessarily mean that packets > 1500 bytes are being used.
Maybe load up wireshark on the PC and take a trace while you are accessing both the webserver and the NAS. Most routers don't do jumbo frames, and certainly your ISP won't. Using the ddns name means that your traffic will be going through your router.
