各位大家好小弟目前在測試IPv6 and IPv4 互相轉換問題 ------ _______ ------ | only | | Route | | Only | | IPv4 |-------------|(NAPTD)|-------------| IPv6 | |------| |_______| |------| v4 PC IP 200.200.200.200 gateway 200.200.200.254 DNS 8.8.8.8 v6 PC IP 2001:4432:5641:2:341:234:21:54 gateway 2001:4432:5641:2:341:234:21:254 DNS 2000:ffff::808:808 如果我從 IPv6(only) 端的PC 去Ping IPv4(only) e.x. ping 2000:ffff::8c8c:8c8c (200.200.200.200) 是正可運作的有Request 有Reply 但是如果從 IPv4(only) 端PC 去Ping IPv6(only) 卻無法運作出現 "目的不可達"的訊息再naptd 設定裡有設定靜態路由 Do you want to create a pool of public IPv4 addresses that will allow incoming connections to be dynamically mapped to appropriate IPv6 addresses? [y/N] y Enter the first public IPv4 address pool to use. starting IP: 192.168.1.123 ending IP (inclusive) [192.168.1.123]:(enter) Do you want to create static mappings of public IPv4 addresses that will allow incoming connections to reach IPv6 hosts? [y/N] y IPv4 address: 192.168.1.123 IPv6 address: 2001:4432:5641:2:341:234:21:54 但當我 v4 PC端 Ping 192.168.1.123 時出現 "目的不可達"的訊息去Linux 底層 tcpdump 看封包時發現都是問ARP的封包於是我嘗試過手動設定ARP 但是ip neigh 已經有相同MAC 的IPv6 IP 所以會出現已存在的錯誤訊息再去跟IPv6 ping IPv4 的封包相比初步研判好像是封包沒有進到naptd 這套軟體裡請問各位前輩是否有人有相同問題或是有解決方法可以參考?? 還是說Naptd 的設定有錯誤?? 謝謝 TOTD CONF forwarder 8.8.8.8 forwarder 168.95.1.1 prefix 2001:4432:5641:2:: port 53 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 114.35.110.23
