How do I pass traffic through a central UTM from two separate sites?

Question

I currently have the following setup: Site B >>> Site A <<< Site C, with A-B and A-C being IPSEC VPN connections. I am looking to pass traffic from Site C to Site B through Site A, but I'm not sure how I accomplish this.

I tried to define static routes, and NAT, but I feel like I'm looking in the wrong place. Any suggestions on how to set this up? Currently, Site C cannot even ping Site B.

Hello MarkBruchkowsky1 , 
 you have to put the Remote Lan on the other site B/C from the vpn tunnel and also the local Networks on A 
 E.g. Site A/B 
 For Site A: Local Networks Site A Site C 
 Remote Networks Site B 
 For Site B: 
 Local Networks: Site B 
 Remote Networks: Site A Site C 
 
 The same thing you have to do for Site A/C 
 Afterwards you yust have to set firewall rules 
 Source: Site B Site C 
 Services: Any 
 Destination: Site B Site C
