If I change router- do I need to reset up double VPN router system (pls read)

Hi all- I set up a double router using GLi net routers to mask my IP address when traveling. I use the travel router to connect to the router abroad and it automatically pulls in my USA IP address. I need to change my USA router (old router stopped working) do I need to reset anything up to keep the double router situation good/workinf? Will this be impacted?

I am not tech savvy at all so any help would be appreciated.

You will have to port forward again. Because your GL.iNet router will get a new local private IP.
