how to hide OpenVPN handshake fingerprint with obfsproxy?

Post by hadi_83 » Wed Dec 25, 2013 6:49 pm

my ISP blocked OpenVPN. I understand SoftEther does not provide any configurable options for OpenVPN.

OpenVPN handshake is very recognisable. I managed to install obfsproxy on windows. is there any way I can use it?

if not, is there any other way to hide my OpenVPN traffic from my ISP?

PS: I can't use SoftEther client as it's not available for Mac OSX :( now me and all my friends are blocked having access to free information in IRAN.

MAC OSX, is a Unix-like system, it should work, since the softether server supports linux...

I can't compile the linux client. it may be linux look-alike, but it needs a little time to test and adapt to OSX. without SoftEther client, I cannot use their propiatery vpn protocol (which by the way works just fine in Iran).

for that very reason, why not just port it to OSX? it's not open source, so I can't do it myself. Anyone from SoftEther can help? that could pave the way for iOS as well.

Install any Linux/Windows to VirtualBox, connect to SE server and use it as gateway.

that's actually impossible. My laptop has router as a gateway and consequently the virtual linux will have my laptop as gateway.

if I change my gateway to virtual linux IP, then It would be a loop between my laptop and the virtual linux.

Hello hadi_83!

Use hardware router and it is becomes possible.

Hi hadi_83!
I have made some mistakes)
You can do it without router, with VirtualBox.

1. Install any Linux on VirtualBox with 2 virtual netcards:
- Bridge to real netcard(link to your provider)
- Virtual Host-Only Ethernet adapter
2. Download and install SoftEther client for linux
3. Clear all settings on real netcards on laptop.
4. Configure Bridge virtual netcard as your internet connection to your provider
5. Connect to SE server.
6. Use Virtial Host-Only Ethernet adapter(default 192.168.56.0/24) and use linux address from this subnet as gateway.

it's not possible mate. just think about it for a second. I need a dedicated hardware to use as router, which is too complicated. why doesn't SoftEther support mac? it's more popular than Linux and most of linux client code doesn't need changing.

if it was an open source protocol, someone would've done it.

Someone from SoftEther team?

Try, it is easy. I have made it with VirtualBox, without any hardware router.
