i m using r7800 with 19.07 for past 2 years. i did a change to firewall config which turns out to be the dumbest move anyone could make.
I have 3 zones, lan, wan and dmz. i have set reject to input and forward traffic on all three zones and lost access to the router. with access being lost, i'm not sure how to reset the router config and revert to last backup either. please help me get out of this mess i created.
