Hi i have configurate a maindomain.com to 192.168.1.110 to specific port 8080...

but now... i need use all ports... is it possible?

like... maindomain.com: 8081  maindomain.com:7568 maindomain.com:7896

and more to use ssh and etc?

Hi, one port = one domain/subdomain, multiple is not possible to one domain
