I just tried this setup with iOS 4.2.1, the require-mppe-128 option works fine:

pppd[18791]: MPPE 128-bit stateless compression enabled

and tcpdump shows that packets are encrypted. Maybe something has been changed between the earlier versions of 4.x and 4.2.1.

Nice article! Helped me through the dns issue I had.

Looking at the questions about not being able to access internet via VPN: Yo might want to enable ip forwarding on the pptpd server. If you define a range of vpn client addresses outside our own subnet, you need to route packets between the ppp0 and eth0 iface:

To enable:
echo 1 > /proc/sys/net/ipv4/ip_forward

Thx, Guido

Raul,

Try changing the lines
–
ms-dns 208.67.222.222
ms-dns 208.67.220.220
–
with the dns services of your provider or try 8.8.8.8 (google dns)

Hi, I’m following your guide and now i’m able to connect my iphone to the pptp sever.

I get the right client IP address, and i can access the internet perfeclty but only using IP address, the name resolution is not working.

Any tips about the push of the DNS server addres?

I have the ms-dns line on options.pptpd but seems to do nothing.

Regards

[...] 比较简单，没有特殊安全性需求的，推荐优先选择这种。搭建方法直接参照此文就行。一个 pptpd 就搞定了。注意别忘了打开 [...]

I have found that u must connect to Wifi first before anything else (naturally). VPN takes some time to negotiate. This gives your bandwidth hungry iPhone 1-15 seconds to roam free on the insecure network.
I guess just makes sure EVERYTHING on the iphone does not store any passwords which gives you the few seconds necessary to connect securely and then type your passwords in when prompted (mail, chat, FB etc..). If you do have stored passwords the iPhone will spill its guts before you have time to connect the VPN.
Apple should make a feature in the VPN section that forces all traffic over VPN regardless of network status (i.e. as soon as there is network – connect VPN – surf) to make it truly a secure option for jumping on evil Wi-Fi networks.

Kevin, copy the options.pptpd right from the example I put here. it probably should work then. It’s a virtual network so the ip settings don’t have anything to do with the external ip
