I have my wordpress multisite setup in LAN network. I also setup dynamic DNS (eg. www.mysite.com) which is directed to my router's public IP (eg. 10.10.10.10). My router will port forward any request to my server's IP (eg. 192.168.0.100).
When I tried to view the wordpress site from another device in my LAN network by typing in my server's IP in the browser, the site showed up nicely. But when I tried to view the site from a device outside of my LAN network by typing in the dynamic DNS name or my router's public IP, the browser showed that there was an error. Sometimes it show timed out error and sometimes it show that a network change has been detected.
The site URL and wordpress URL was set to (http://192.168.0.100) for this example.
Is there any way I could configure so that the site could be viewed from outside the LAN network? Any solution is much appreciated.
