I configured my server as github sends. And I can connect normally when the <address> of my clientinfo.xml is set to my local ip. But when I switch to ip WAN I can't connect. I have already opened and redirected ports 6900, 6121 and 5121 on the router. When I check if the ports are open, the website https://www.yougetsignal.com/tools/open-ports/ shows that they are open. conf/import/char_conf.txt login_ip: 192.168.15.4 char_ip: ragnarokserver.duckdns.org char_del_delay: 0 pincode_enabled: no conf/import/map_conf.txt char_ip: 192.168.15.4 map_ip: ragnarokserver.duckdns.org clientinfo.xml <?xml version="1.0" encoding="euc-kr" ?> <clientinfo> <desc>Ragnarok</desc> <servicetype>korea</servicetype> <servertype>primary</servertype> <connection> <display>Local</display> <address>ragnarokserver.duckdns.org</address> <port>6900</port> <version>55</version> <langtype>1</langtype> <registrationweb>www.ragnarok.com</registrationweb> <yellow> <admin>2000000</admin> <admin>2000001</admin> <admin>2000002</admin> <admin>2000003</admin> </yellow> <loading> <image>loading00.jpg</image> <image>loading01.jpg</image> <image>loading02.jpg</image> <image>loading03.jpg</image> <image>loading04.jpg</image> <image>loading05.jpg</image> <image>loading06.jpg</image> </loading> </connection> </clientinfo>
