I have two Sophos UTM in two different networks. Both UTMs are sitting between external and internal subnet. I want both UTMs to be able to initiate connection.
For gateway setting gateway type for both is set to initiate connection and gateway is public ip of other UTM. Remote networks contains local ip of a host in another network, right now I want to tunnel to one host only.
In ipsec connection interface is set to external and local network is a local host who will be allowed to be a part of this tunnel. But connection is not initializing.
I have similar local ip configuration at both places.
172.16.0.0/24 public subnet
172.16.1.0/24 private subnet
172.16.2.0/24 Application subnet
Right now I have only one instance running in both application subnet, both having IP 172.16,.3.5
So I in gateway setting I have setup remote host- 172.16.3.5
Also in ipsec connection setting local network is set to 172.16.3.5
What is going wrong in setting up the connection ?
When I go to site to site it shows me-
