Hello and thank you for your swift reply.
Ok, in that case the suggested approach won't work. Since there's no "real" way to set the port used in links generated by PRTG, you won't be able to effectively resolve this, but you can implement some workarounds.
For instance, if you're worried about alert/notification E-mails, you can define any custom content if you switch to "Text with custom content" alerts. You can then manually create the links in your E-mail. For instance for a link to the sensor:
More details about placeholders are available here:
For HTML E-mails, changes to the content are not officially supported. But you could modify the files in this folder to customize HTML E-mails:
|C:\Program Files (x86)\PRTG Network Monitor\webroot\mailtemplates|
Keep in mind that PRTG updates will automatically overwrite these files, so you may want to back-them-up before updating, otherwise you'll lose the changes when when you update. And keep in mind that this change is not officially supported.
