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.

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

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)

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

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.

It’s a virtual network so the ip settings don’t have anything to do with the external ip
