The issue is still happening

So, my friend and I decided to start a server for Attack of the B Team.. We gathered our resourses and created a nether portal.. We then decided that it would be a good idea to create seperate "Bases". As I created the "base" I added a nether portal. Now everytime I go to the nether and return, I get sent to the first portal we created together instead of the one built on my own. Note: I am a good distance away in the overworld but, the portal I build keeps taking me to the original portal in the nether.. Any help? Thanks in advance!
