In the page settings if you want to redirect to another page and pass a querystring to that page there are two ways to do it.

Both use the LinkURL setting in the Advanced|Other Settings section of the page settings.

The most common way is to place  a full URL in the location field e.g. "https://www.dnnsoftware.com/default.aspx?{Querysting}"
Where {querystring} is the querystring, including TabID you want to pass.

However if the current site has multiple portal aliases this isn't optimal.

The other way is to put the following in the location field "/{page}?{Querystring}&~". The addition of '&~' at the end stops DNN from adding 'http://' in front of the content of the location field. The "/{page}" portion should be a path name from the site root that is recognizable either from the name (friendly) or including a tabid identifier.
