if I put accept all 0.0.0.0/0 means this server is totally open for any ip ?

ACCEPT     all  --  0.0.0.0/0            0.0.0.0/0

is this means allow all ip from all port?

but I still can not visit the server except I go through the allowed ip address

and if I put this line in any line, did I make this server totally open for any connection?

the full iptable list is below
