NAT Port Forwarding有錯誤 - BBS

先感謝之前大大幫忙 NAT終於架成功了

目前配置是 外網-------FreeBSD-------XP
(140.115.208.168) (192.168.112.168)
(192.168.112.254)

可是我現在想要從外網遠端到XP那台

查了一下資料 XP的遠端桌面連線是用port 3389

所以我想用IP FORWARDING把140.115.208.168:3389轉到192.168.112.168:3389

照著一些網上教學文件 卻不得其果

爬了版上的文尋求解答 卻看不太懂

只好自己PO一篇

目前的設定

---------GENERIC--------------

options IPFIREWALL
options IPDIVERT
options IPFIREWALL_DEFAULT_TO_ACCEPT
options IPFIREWALL_VERBOSE
options IPFIREWALL_VERBOSE_LIMIT=10
options IPFIREWALL_FORWARD
options DUMMYNET

---------/etc/rc.conf---------------

----------/etc/natd.conf--------------

redirect_port tcp 192.168.112.168:20 140.115.208.168:20
redirect_port tcp 192.168.112.168:21 140.115.208.16821
redirect_port tcp 192.168.112.168:3389 140.115.208.168:3389


然後natd有錯誤訊息

natd: Unable to bind divert socket.: Address already in use

試過版上的方法砍掉服務再開 還是不行

繼NAT之後 搞這個又搞了兩三天 囧
