Hello,
We took up a VPN with a partner between a Sophos UTM 9 and firewall under Openswann.
This VPN seems totally functional for us and for our partner (No IPSec errors) but we cannot reach the web application they host.
The most disturbing, it's because when they make a ping on a machine in our LAN, we succeed in reaching the application but only in that case! As soon as they stop the ping, the application is not accessible any more.
We don't understand any more and look in vain for a solution for weeks...
Here is the topology of the VPN:
192.168.8.0/22 - > 83.X.Y.Z ( public IP) - > 195. X.Y.Z (public IP) - 10.107.10.0/25
192.168.8.0/22 is our LAN and 10.107.10.0/25 is their LAN.
IPSec policy :
IKE encryption algorithm: 3DES
IKE authentication algorithm: SHA1
IKE SA lifetime: 28800
IKE DH group: Group2 MODP 1024
IPsec encryption algorithm: 3DES
IPsec authentication algorithm: SHA1
IPsec SA lifetime: 3600
IPsec PFS group: Group2 : MODP 1024
Strict policy NO
Compression NO
I hope you can tell me where we are wrong...
Thanks !
Reuter
