Hi Guys,
We have 3 branch offices A and B and C.
A is the master office and we want to build a IPsec tunnel from B and C to A in order to access the servers behind the Office A.
on the Office A we are already using openVPN tunnel for the users to access the servers when they are on the road.
on the 3 offices are using Opnsense A10 Hardware.
is this even possible to use ?
Sure, just install the tunnels and check that your networks doesn't overlap
Thank you for your answer,
do you mean we can have two SSL tunnels ?

Of course, you can configure as many servers as you want. You just need to be wary of the port number used.
In IPsec the port doesn't matter and you can also span multiple tunnels over one Phase 1 connection.
Cheers,
