[Optical Network Terminal]----[Huawei VoIP Gateway]--LAN--[SGW]----[Switch]----[Cisco Wireless Router]
- So HW VoIP Gateway acts as an router and has a public IP address.
- Then, the Security Gateway was connected to the gateway with private IP address but has been demilitarized (DMZed), that makes all traffics goes to SGW. (I know you're gonna say why not put SGW after the ONT instead of the VoIP gateway, but ISP configured that ONT is to work with VoIP gateway only; even with mac addy clone)
and now i wanna setup IPSec for iPhoneand Android, not L2TP over IPSec.
so now i want to setup pure IPSec from iPhone by only going to Settings > General > Network > VPN > Add VPN Configuration > IPSec.
So i filled up description, server (hostname), account, password, and secret which is under
Authentication type: Preshared key
then VPN > On
But all i've got is
The VPN server did not respond.
my config for IPSec is:
Interface: External
Local Networks: Internal (Network)
Virtual IP pool: VPN Pool (IPSec)
Policy: AES-256 PFS
Authentication type: Preshared Key
Preshared Key: ****
Confirm: ***
Enable XAUTH: Ticked (Yes)
