araltan :
I have a lot of forwarded ports in my router(I don't remember the ports). The only problem is that I forgot the password for my router and I want to forward some other ports. I can reset the router in order to access it again but I'm afraid that my forwarded ports will get deleted. Any help would be appreciated.
If you reset the router back to factory state, it will indeed wipe out all of your existing settings.
The only way around this is to know the current password and document all of that.
For future use, most routers have an export feature, whereby you can export the current settings out to a file.
Save that, and if you have to reset it in the future...you can recover from that file.
