Please, how to open my port 51000 and 50000 inside router ?

Sucess open port 22 and 49000.

The port for OSCAm not open !

I try this comand !

uci add firewall rule
uci set firewall.@rule[-1].src=wan
uci set firewall.@rule[-1].target=ACCEPT
uci set firewall.@rule[-1].proto=all
uci set firewall.@rule[-1].dest_port=50000-51000
uci commit firewall
/etc/init.d/firewall restart

Is possible to remove all firewall and open all my ports ?

hi

basically for NAT you have to specify a source and a target
  http://wiki.openwrt.org/doc/uci/firewall?s[]=firewall

for a range use 'port-port'
for single port use 'port'
for every single port you have to make a rule(seems comma separated doesnt work)

nano /etc/config/firewall

  config redirect
        option target 'DNAT'
        option src 'wan'
        option dest 'lan'
        option proto 'tcp udp'
        option src_dport 'port-port'
        option dest_port 'port-port'
        option name 'starcraft'
        option dest_ip 'LAN_IP'

/etc/init.d/firewall restart
