Thanks. I was reading pptp wasn't as secure as openvpn (i guess open on uses l2tp or whatever it is). Also some locations such as china block pptp, so wasn't sure if to use pptp, as I had come across that article you posted earlier

| Post subject: | iPad & VPN |
Hi, I have an iPad and am looking at getting a Linode (I used to have one previously) for multiple uses. What I would like to be able to do is setup a VPN on a Linode, to which the iPad could then connect to when I'm not in the UK or an a public network. What I would like to know is if someone has has some experience of this and what VPN service they have used on their Linode. Thanks, |

I took the simple route and installed PPTPd on my Linode in London. And I've successfully connected my iPad to that VPN and surfed around, so I know it works. If I remember correctly, I followed this tutorial (feel free to replace the "nano" commands with your editor of choice): http://akensai.com/linode-vpn/ |

PPTP is a broken security protocol. Originally cracked way back in 1999, with minor "fixes" over time that made it marginally "less cracked" but still not secure, and then recently totally cracked once again (via ChapCrack and other tools). MS has no interest in maintaining MS-CHAPv2 and no security person worth there chops would even consider using it. That said, security is always a tradeoff. How much is "good enough" depends on what you're protecting. You don't install a million dollar safe to protect a hundred thousand dollar ring. |

I wouldn't go for pptp although as for alternatives, there is an article in the Linode Library about installing and configuring OpenVPN which would be a better choice over pptp. |

OpenVPN is nice, but it doesn't solve the OP's problem, since it's not natively supported by iOS. Valid options are: - PPTP - L2TP/IPSec - Cisco IPSec - Juniper JunOS Pulse (via app) - Cisco AnyConnect (via app) The PPTP and L2TP options support RSA SecurID or CryptoCARD as an alternative to MS-CHAPv2 iOS does support third party (non-integrated) VPN solutions via an API, hence the two apps I listed. However, the API is undocumented, and only available to vendors on invitation. This is why there is no OpenVPN client despite it being technically possible without jailbreaking. |

Thanks Guspaz. I'm running CentOS on m Linode, so what solution do you suggest out of pptp and l2tp and what's the name of the service I need to install on my vps? I'm not familiar with tsa and crypto. |

Unfortunately, I've never used the VPN support on iOS myself, so I can't really recommend something specifically. PPTP is likely to be blocked by most mobile carriers since it uses GRE (and not TCP or UDP); I think one of the other options is more likely to get through. |

I've used VPN on iOS before (and android) L2TP/IPSec works well on the server side I use openswan. The downside is you're stuck to using set ports which are often blocked unless you pay to have VPN access in hotels/airports etc. |
