NethServer Version: NethServer release 7.3.1611
Module: Ipsec tunnels
My silly NethServer installation use this kind of setup.
3 network adapters
1 Red Static IP 172.20.1.99/24, GW 172.20.1.254
1 Green Static IP 172.31.3.1/24
1 Blue Static IP 172.31.251.1 (cable not connected).
At the same DSL router it's also connected an USG20W appliance by Zyxel, capable of different things... IPSec tunnel for instance.
WAN 172.20.1.252/24, GW 172.20.1.254
I cannot use two public connections so i were trying to create an IpSec tunnel between them for test.
NethServer fully updated, USG20W Firmware Version 3.30 BDR9, the latest available.
(A little reminder for all: I used IpSec for connecting Zyxel USG's between them several times, also for connect USG with IpFire or DSL consumer routers, TP-Link and NetGear among others. Be kind, I'm still a newbie on the task but non that noob...)
The tunnel was created as DNS Local/Remote ID, with a passphrase, AES128 as algorithm and SHA1 for checksum (Ike and ESP). Time key exchange was triple checked (86400/3600), PFS was enable on both side for Phase1 and Phase 2 (DH2, default for NethServer).
Obviously, still not working.
Italian interface of the Tunnel setup of Nethserver says
Task completato con errori
# (codice d'uscita )
(for non-italian speaking people...)
Task completed with errors
# (exit code)
but obviously exit code is missing... And i cannot understand whats' going wrong.
The strangest think for my little experience is... i have no kind of dialog between devices into Zyxel's Log.
I'm not used and skilled enough for correctly reading and understand the logs from Linux/NethServer, but i'm quite used to understand the Zyxel appliance's log, and seems no kind of data exchange/messages between two installations.
So: what i'm doing wrong?
