Thanks for the response. It seems that we are quite similar setup-wise, but I must be missing something here.
I tried to follow that post as well, but still wasn't having any luck.
When you set yours up, did you set up any DNS zones, or did you just add the website since no-ip.com is your dns service? I think the problem for me lies somewhere between no-ip and the dns zones on ISPConfig. Just so maybe you can compare, on no-ip.com i have the domains set up like this:
website2.com IP: 18.104.22.168:8080
Each host is set up as a Port 80 redirect (I have to do this as my ISP blocks port 80).
I am trying to set up the server, so that each domain name points to its own website, which I am trying to create (unsuccessfully) in ISPConfig.
Honestly, I don't know exactly where the problem lies, and admittedly - I'm pretty much a noob at this. If someone can help me out, I would greatly appreciate it. Thanks in advance for your time and effort in teaching me.
