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

Yes… The server only has an external/remote ip….. Its on a dedicated line… 71.43.227.78……

option /etc/ppp/options.pptpd
localip 71.43.227.78
remoteip 71.43.227.78

Kevin:

Jul 23 18:10:10 rrcs-71-43-227-78 pppd[4437]: local IP address 71.43.227.78
Jul 23 18:10:10 rrcs-71-43-227-78 pppd[4437]: remote IP address 71.43.227.78

doesn’t look right, same ip for remote & local?! did you edit /etc/pptpd.conf described as above?

Kevin, do you use a custom kernel or one deliverd with your distributions? and did you make sure your external interface is eth0 ? iptables -L (capital L) as root

eeh.. No errors now.. i moved “RELATED,ESTABLISHED” up to the line like it was supposed to be now no issues… iptables -l still has the same outprint

iptables v1.3.5: Unknown arg `–state’
Try `iptables -h’ or ‘iptables –help’ for more information.
/etc/rc.local: line 10: RELATED,ESTABLISHED: command not found

hmmm
