-The website is locally hosted on the LAN, which is available from the Internet
-From the LAN and using a web browser, I enter the FQDN of that website
-The packets goes to the default gateway, most likely out on the Internet but don't come back to the LAN. So therefore, from the LAN, I am unable to access the website.
I remember, a few years ago, I enabled something (I think it was a simple check box but not sure) in DD-WRT that was making the packets route back to the LAN were I was able to see a locally hosted website from the LAN. But I don't remember how I did this.
Thanks for your help,
