[Linux] Allow from localhost 失效 @ Ubuntu 14.04 / Apache 2.4.7

[Linux] Allow from localhost 失效 @ Ubuntu 14.04 / Apache 2.4.7

週末把某檯機器更新後，發現原先寫的 apache.conf 失效，主要是 Allow from localhost 這段：

<Directory /data/path>
AuthType Basic
AuthName "Password Required"
AuthUserFile /path/auth_pass

Order allow,deny
Allow from localhost
# Allow from DeviceIP


Satisfy any
</Directory>

直到我加上 DeviceIP 後才行。

$ wget -O /dev/null http://localhost/service/api
Resolving localhost (localhost)... 127.0.0.1
Connecting to localhost (localhost)|127.0.0.1|:443... connected.
WARNING: no certificate subject alternative name matches
        requested host name ‘localhost’.
HTTP request sent, awaiting response... 401 Unauthorized

Username/Password Authentication Failed.

追了一下，發現是 iptables 的設定，把這條拿掉就行了：

iptables --table nat --append POSTROUTING --jump MASQUERADE

此筆記是用來記錄，iptables 的影響 Orz
