The above L2TP one-button installation package is also based on Openswan + XL2PTD source code compiled, I was also reference GKP build VPN, at that time with the 64-bit CentOS 6.2, has been unsuccessful. Now the space moved, I simply put the Linode system reinstall the 32-bit CentOS 5.6来 do the experiment.

Based on Ipsec-tools installation
Some say there is a problem with Openswan to install L2TP vpn,android connections. (Original: As Openswan is reported has issues with Android ICS (byte 7 of ISAKMP Nat-oa Payload must to zero))

So I built this method, build process than Openswan + xl2ptd smooth, iOS can successfully connect VPN, but just can't access the extranet. Individuals previously suspected the IP settings of the Linode LAN, but after testing the above methods, the idea was denied.
