Please post your configuration. Without that, we're just guessing. To export and paste your configuration (and I'm assuming you are using WebFig or Winbox), open a terminal window, and type (without the quotes) "/export hide-sensitive file=any-filename-you-wish". Then open the files section and right click on the filename you created and select download in order to download the file to your computer. It will be a text file with whatever name you saved to with an extension of .rsc. Suggest you then open the .rsc file in your favorite text editor and redact any sensitive information. Then in your message here, click the code display icon in the toolbar above the text entry (the code display icon is the 7th one from the left and looks like a square with a blob in the middle). Then paste the text from the file in between the two code words in brackets.
