G'day,
I am trying to configure a VPN (L2TP/IPSec) to run on my billion device but I cannot get a connection to work, whether I use PPTP or L2TP (with or without IPSec). I've tried a windows machine, iphone and android in every combination I can think of, and I just can't get it to work.
Note that I am using preshared keys as the billion doesn't support certificate based ipsec.
Can anyone point me in the right direction on how to get a VPN working with this device, or even just how I can reasonably debug it. All I get on windows 7 is Error 789, on the android I get errors ranging from server not responding, server hung up to wrong username and password (not correct).
