SAMSUNG ACE - L2TP over IPSEC

Hi my friends,

My first round was with IPHONES using cisco vpn, so far I could connect only 1 iphone, I haven't luck with the rest of them. 

Now, I´m trying to connect a Galaxy ACE with android 2.3.4. . I've been checking each parameter according to threads from astaro.org but I´m getting an error message " can´t connect with network ". I´m using L2TP over IPSEC with PSK. 

Here is what I did:

On ASG:
Remote Access->L2TP over IPSec
Interface: External (WAN)
Authentication: Preshared key
Preshared key: any PSK of your choice
Repeat: repeat PSK

Assign IP address: IP address pool
Pool Network: VPN Pool (L2TP)

Authentication via: Local
User and Groups



Network Security->NAT->Masquerading

Network: VPN Pool (L2TP)
Interface: External (WAN)
Use address: >

Enable the masquerading rule.

Network Security->Packet Filter

Source: VPN Pool (L2TP)
Service: Any
Destination: Internal (Network)
Action: Allow
Time Event: >

Enable the packet filter rules.

On the phone:
VPN Name: Any name you choose

Set VPN server: hostname.astaro.com

Set IPSec pre-shared key: whatever key you chose on ASG

Enable L2TP Secret: leave unchecked

DNS search domains: not set

IPSEC logs are showing this:

    I think you want 'Destination: Internet'

    Enable L2TP Secret: leave unchecked

    I'm not sure what they mean by that.

    DNS search domains: not set

    Again - not sure what they mean.  However, that reminds me - do you have 'Remote Access >> Advanced' configured?

    Cheers - Bob
