Dummy linux / firewall

[Dev_BR]

I have no experience with linux, but I have notions about the command line.
Could someone give me information on how to see, edit firewall file ?

I know how to acess router with putty and I can reach firewall subdirectory

thanks

Google the command "vi"

You can also try Nano

From the command line

opkg update
opkg install nano

then to run just type: nano

Either way, make sure you backup the firewall file before you
start editing and/or making changes.

cp file1 file2

Should run you a copy of the file
