我正在尝试将端口80转发到8484
sudo ipfw add 100 fwd 127.0.0.1,8484 tcp from any to any 80 in
这适用于我的本地计算机（OS X 10.6），但不适用于我的服务器OS X 7。
每当我添加我获得的规则后尝试连接到任何URL时 找不到
在此服务器上找不到请求的URL /login.htm。
这是添加规则后ipfw show的输出：
00100 0 0 fwd 127.0.0.1,8484 tcp from any to any dst-port 80 in
01000 0 0 allow ip from any to any via lo0

添加规则时，我无法确定转发是否确实有效。有没有办法测试这个？此外，什么可能阻止转发规则被识别。
我尝试刷新所有规则并添加一条规则
00100 0 0 fwd 127.0.0.1,8484 tcp from any to any dst-port 80 in
但这也没有效果。
