Hi,
my internet provider gave me a wpad.dat to use a intranet proxy. I need to add it to my routing and I guess /etc/dnsmasq.conf is the correct file but I tried and added:
dhcp-option=252,http://www.xxxxx.com:80/wpad.dat
and I didn't work.
I tried to google and it didn't really help me.
I would really appreciate some help.
Thanks
System
Hostname OpenWrt
Model TP-Link TL-WR941N/ND v2
Firmware Version OpenWrt Chaos Calmer 15.05 / LuCI (git-15.248.30277-3836b45)
Kernel Version 3.18.20
Hey there.
There are hundrets of browsers out there, having an individual understanding of how to treat PAC, if at all. You might, for example, have no luck trying to make this work with smartphone browsers.
To my knowledge, the very best way (read: The way to work on the majority of browsers) would be to set up wpad.
https://en.wikipedia.org/wiki/Web_Proxy … y_Protocol
In short: Setup a host called "wpad" inside your network, make sure it can be resolved by DNS and make it deliver the file under the name of "wpad.dat".

Stephan.
1) Firefox and MacOS doesn't support dhcp-option=252. See http://findproxyforurl.com/browser-support/
2) Try to use DNS instead as golialive mentioned. You need a web server to host the wpad.dat script. The wpad script needs to be located in the document root of the web server. The web server must be configured for .dat files with a MIME type of "application/x-ns-proxy-autoconfig". See http://findproxyforurl.com/deploying-wpad/. You can use uhttpd, it's already contains MIME types for pac and wpad.dat
Add to /etc/config/dhcp:
config 'domain'
option 'name' 'wpad'
option 'ip' 'webserver IP address'
Make sure the client can access this file using the url http://wpad/wpad.dat
See also https://auth0.com/blog/heads-up-https-i … sing-wpad/ and https://nakedsecurity.sophos.com/2016/0 … erability/ about wpad attacks. It is better not to use web proxy auto discovery and manually specify the path to wpad.dat in network settings and browser settings.
