Whenever I create a subdomain "or simply setting the hostname" I get a shared ip error. This is my setup I register my domains through 1and1 I set them all to the same IP address my server uses I created two subdomains on 1and1 The main domain site in ispconfig works which is jaikobcreate.com When I go to create new site -- i set the hostname to the subdomain part I want then the main domain name, and I have it create the records for me in dns. I am behind a router. but I am using different local IP addresses 10.129.0.2 -- local 10.129.0.3 -- local 10.129.0.4 -- local And my WAN address (which I used for my domains) id 71.13.92.xxx so in retrospect I have this setup: 1and1 Domains Registered: jaikobcreate.com 71.13.92.xxx xxx.jaikobcreate.com 71.13.92.xxx Router - WAN - 71.13.92.xxx LAN 10.129.0.xxx 3 static LAN addresses 10.129.0.2 10.129.0.3 10.129.0.4 my linux server box had virtual network interfaces with the local static IP's configured into it. ISPConfig see's the IP addresses When I make a new site in ispconfig I use one of the 3 local IP's for each domain i have. I never use 1 IP for more than 1 domain. When I want to make a subdomained host I make a new site, and change the hostname to the first part of the subdomain. then i fill out everything else. my main DNS record for jaikobcreate.com is set for 10.129.0.2 the A record - www is set to 10.129.0.2 in DNS the A records are set for the hostname of the subdomain, but they are a different IP address then the main record. why is it giving me a shared IP error, when indeed its not a shared IP?
