Environment

• Liferay 7.1

Resolution

• In portal.properties, the redirection property is defined as below
  

  ##
  ## Redirect
  ##
  
  #
   # Set this property to "ip" or "domain" for the redirect security method. If
   # set to "domain", the portal will only redirect users to domains listed in
   # the property "redirect.url.domain.allowed". If set to "ip", the portal
   # will only redirect to domains whose IP address resolve to an IP address
   # listed in the property "redirect.url.ip.allowed".
   #
   #redirect.url.security.mode=domain
   redirect.url.security.mode=ip
  
  #
   # Input a list of comma delimited domains which the portal is allowed to
   # redirect to. Input a blank list to allow any domain. Specifying a domain
   # with a leading "*." allows redirects to subdomains.
   #
   redirect.url.domains.allowed=
  
  #
   # Input a list of comma delimited IPs which the portal is allowed to
   # redirect to. Input a blank list to allow any IP. SERVER_IP will be
   # replaced with the IP of the host server.
   #
   redirect.url.ips.allowed=127.0.0.1,SERVER_IP

• According to the stated information on each property, it can only be used in the following two ways. 
  1. IP: If set to 'IP' mode the property should be used as follows​ and redirection will happen based on defined IP address
  

  redirect.url.security.mode=ip
  
  redirect.url.domains.allowed=
  
  redirect.url.ips.allowed=127.0.0.1,159.113.202.96​
  
  SERVER_IP  is replaced by the IP address of your host machine

  2. Domain: If set to 'Domain' mode the property should be used as follows​ and redirection will happen based on defined domain
  

  redirect.url.security.mode=domain
  
  redirect.url.domains.allowed=dxp-test.myplanlink.com
  
  redirect.url.ips.allowed=127.0.0.1,SERVER_IP​
