3 firewalls and 1 VPN

Mbaray
Hello,

We use a Netgear UTM9S in our LAN and a Sophos UTM9 in our cloud to make a VPN connection. The VPN is up, no problem with that. But, in our cloud, we have 2 UTM9, one for the VPN connection and the other which protects our datacenter in the cloud.

The VPN connect our LAN in 192.168.1.0/24 to the UTM9 in 192.168.0.0/16. We can ping its interface. The other UTM9 have an interface in 192.168.0.2 and an other in 192.168.3.1. So both UTM9 can see each other, but we can't ping the interface in 192.168.0.2. Both UTM9 authorize our LAN network and the public address of our ISP.

I join a representation of this architecture.

What we forget to do?

Thanks for your help.

Best regards,

Mehdi BARAY

    Yup everybody!

    No idea? That's really weird because, the first time I changed the netmask of each network, everything gone fine... The VPN just go down and re-up one time after that and nothing work after.
