Hello, i have a project at home i want to portforward my 2 DVR device so i can view it from outside. i want to use ddns because i have to 2 ISP just in-case one of the ISP is down i can still view it, but my problem is there is no dual wan option on edge router like in pfsense. is there any solution that i can try ?

You can do dual wan on an edge router, but as far as I know, the setup is all done from the command line.
