由Nokia IntelliSync年代試玩 OpenLDAP LC CentOS 5 試驗機,到變成Squid Proxy 已經用超過十年。基於CentOS 5 已經EOL一段時間。係時候準備新嘅Proxy作為replacment
因為目前需要試iOS Device 經Proxy, 只需要用Proxy Server黎試iOS嘅Global HTTP Proxy。所以唔需要大費周章去再起新Linux。pFSense呢啲Soft Router正正做到自己需要嘅Test
pFSense setup相信唔需要講啲咩,因為真係好簡單。Mount起ISO,Boot機,噤制,等完成安裝。
唯一提係安裝係VirtualMachine,估唔到 係到呢家仍然要選IDE HD。好在係pFSense可以config行RAM Disk。
下面嘅URL有好好嘅Setup Procedure作參考。
唯一唔同係自己唔係要Setup Transparent Proxy。
目標Proxy Set up而係Standard HTTP Proxy 加 Proxy Pac file
以下PAC 係好好嘅Sample
Sample PAC pattern
- function FindProxyForURL(url, host) {// If the hostname matches, send direct.
if (dnsDomainIs(host, “intranet.domain.com”) ||
shExpMatch(host, “(*.abcdomain.com|abcdomain.com)”))
return “DIRECT”;// If the protocol or URL matches, send direct.
if (url.substring(0, 4)==”ftp:” ||
shExpMatch(url, “http://abcdomain.com/folder/*”))
return “DIRECT”;// If the requested website is hosted within the internal network, send direct.
if (isPlainHostName(host) ||
shExpMatch(host, “*.local”) ||
isInNet(dnsResolve(host), “10.0.0.0”, “255.0.0.0”) ||
isInNet(dnsResolve(host), “172.16.0.0”, “255.240.0.0”) ||
isInNet(dnsResolve(host), “192.168.0.0”, “255.255.0.0”) ||
isInNet(dnsResolve(host), “127.0.0.0”, “255.255.255.0”))
return “DIRECT”;// If the IP address of the local machine is within a defined
// subnet, send to a specific proxy.
if (isInNet(myIpAddress(), “10.10.5.0”, “255.255.255.0”))
return “PROXY 1.2.3.4:8080”;// DEFAULT RULE: All other traffic, use below proxies, in fail-over order.
return “PROXY 4.5.6.7:8080; PROXY 7.8.9.10:8080”;}
而 Proxy PAC 係今次嘅主菜,相對pFSense / Squid 嘅 Setup,花係PAC試嘅時間係更多
今次目的係iOS Device 行Proxy,經MDM Push Global HTTP Proxy Profile。所以PAC 係Set到Mobile Network會用Proxy,反而係Internal Network唔經Proxy
跟住嘅Post會講經MDM Push左Global HTTP Proxy profile發現嘅 古怪問題
