IPSec Connections PSK

Hi,
i have serveral problems to establish a connection between to lans.The Lans have both dynamic ip´s. The PSK is allways the same.I use the IPSEc Policy: 3DES.In addition to,the configuration is on both sides the same.But if i open the VPN Conn. i come different error messages:

"roes_1": 192.168.xxxx/xx===xxx.xxx.xxx.xxx...xxx.xxx.xxx.xxx===192.168.xx.xxx/xxx
000 "roes_1":   ike_life: 7800s; ipsec_life: 3600s; rekey_margin: 540s; rekey_fuzz: 100%; keyingtries: 0
000 "roes_1":   policy: PSK+ENCRYPT+TUNNEL; interface: eth1; unrouted
000 "roes_1":   newest ISAKMP SA: #0; newest IPsec SA: #0; eroute owner: #0
000 "roes_1":   IKE algorithms wanted: 5_000-1-5, flags=-strict
000 "roes_1":   IKE algorithms found:  5_192-1_128-5,
000 "roes_1":   ESP algorithms wanted: 3_000-1, flags=-strict
000 "roes_1":   ESP algorithms loaded: 3_168-1_128,

Both firewalls have the same config.,the same ipsec policy and the same psk.
What is possible for a correct connection and why does`nt work it.

Thanx and regards

did you read the manual at http://docs.astaro.org/guidebooks/Guidebook-US-ASL-V4_psk_net-to-net.pdf

Hello...

Have a question.. are the Internal networks in the same Subnet? Like...

192.168.1.0 > 192.168.1.0 ?

When its true, then you must change one of this subnet to another subnet like..

192.168.1.0 > 192.168.2.0

We had the same problem like a B - Class Network

172.16.0.0 > 172.16.0.0

This doent work by us, we have the greatest problems and malfunctions in the Tunnel, but the Tunnel itself works..

We have fix this problem, that one of the two internal Networks go in another subnet like..

172.16.0.0 > 172.17.0.0

I hope this are the problem that you have and wish you enough power to fix the problem ;-)

Yes,my Internal net is in the Same Subnet.But the tunnel worked perfect.But since the last Update from Astaro 3 to 4,to tunnel is established but no communication available. The Properties on both sides are exactly the same.

Hi christianwitty,

there was something new from ASL 3 to ASL 4.
When I'm right, there was the need for paketfilter rules which allows the traffic pass trough the tunnel.
Have a look at your logfiles please.
Are you sure the connection is established?
Did you have a automatically generated route on both sides?

HTH
