I have 5 differnt locations, all of which have a Sophos UTM9 firewall. To connect our telephony system, all 5 locations need to be reachable.
I have to possibilities
a) Build an IPSEC tunnel for each location on each firewall. This makes 4 Tunnels on each Sophos UTM9
b) Build a single IPSEC tunnel on each Sophos adding the remote networks accordingly in that tunnel
What is best practice?
Thank you, Matthias
