Fiddler2 direct download

Posted by jpluimers on 2017/06/06

For automated installs that cannot have UI interaction:

The install is “per user” as it is a user-local application; it installs in %LocalAppData%\Programs\Fiddler\Fiddler.exe.

Docs

Note that Fiddler acts as a HTTP proxy. When Fiddler starts, it hooks itself into the default WinINET proxy (which is used by any tool using the WinINET API, including Edge, Internet Explorer, Chrome, but not FireFox).

If you kill your Windows machine before stopping Fiddler, it cannot restore the WinINET proxy, so you have to do that by hand (otherwise you cannot browse web pages any more).

Manual restore:

  1. Run "C:\Windows\System32\rundll32.exe" shell32.dll,Control_RunDLL inetcpl.cpl,,4
  2. Press “LAN settings” (Dutch: “LAN-Instellingen”)
  3. Uncheck the proxy server checkbox “Use a proxy server for your LAN” (Dutch “Een proxy-server voor uw LAN gebruiken”)
  4. Confirm
  5. Close the control panel wizard

Reminder to self: when your PPTP server is behind a NAT, forward both GRE protocol and TCP port 1723

Posted by jpluimers on 2017/06/06

The WAN sides of my Mikrotik CCR1009 are partly behind Fritz!Box routers that do NAT and contain a truckload of port-forwards.

A while ago, I wanted the CCR1009 to do PPTP as Fritz!Box 7360 and 7490: static routes over VPN don’t work (so I could only VPN to the WAN side of the CCR1009). However, it would not pass through the Fritz!Box from the outside.

It appears you need to forward both:

Maybe one day I will ditch the Fritz!Box 7490 and directly hookup the Mikrotik to the NTU: xs4all ftth en Mikrotik router – Google Groups.

But preferably I should follow Don’t use PPTP, and don’t use IPSEC-PSK either (via: CloudCracker blog)

Forward both PPTP TCP port 1723 and the GRE protocol
