We have a number of business partners that have IPSec tunnels using CP firewalls to our clients WG firewalls. I've not worked with the "SecuRemote" client/tool, so I can't speak for it specifically.
Key things to remember: both networks need to have different subnets - you can not have 192.168.10.0/24 on both sides.
In the WG, forming the tunnel is only part of the task, you need to create a rule that permits access from the remote network to the local network (best done as IP to IP to limit exposure).
