since your have a router you have to set you ips in a different way like this:
*********************************************************
CONF configuration files - save the files once you change the settings
*********************************************************
open login_athena with notepad
login_ip: LAN IP < Dont write the word LAN IP. Write the numbers.
port : 6901
*********************************************************
open char_athena with notepad
// Login Server IP
login_ip: LAN IP
port: 6901
// Character Server IP
char_ip: WAN IP < Dont write the word WAN IP. Write the numbers.
port: 6122
*********************************************************
open map_athena with notepad
// Character Server IP
char_ip: LAN IP
port: 6122
// Map Server IP
map_ip: WAN IP
port: 5122
*********************************************************
in lan_support
// put here the LAN IP of your char-server
lan_char_ip: LAN IP
// put here the LAN IP of your map-server
lan_map_ip: LAN IP
// put here the Subnet mask of your LAN
subnet: Subnet IP read here for details >

EDIT: Instead of using those ports use the default qrRO server ports instead
