Route to remote subnet over IPSec tunnel - Cant get traffic to pass?

So, i have three routers:

1. RTR-A:
   • Lan subnet of 172.16.254.11/24 on Eth0
   • Wan subnet of 11.11.11.11/29
   • IPSec tunnel to RTR C
   • "Hairpin NAT" enabled (By default)
   • "Automatically open firewall and exclude from NAT" enabled
2. RTR-B:
   • Lan subnet of 10.1.1.254/24 on Eth0
   • Wan subnet of 172.16.254.1/24 on Eth1
   • Connected to RTR A throug a switch
   • Zero NAT enabled anywhere
   • Static route:
     • ip route 10.1.11.0 255.255.255.0 172.16.254.11
3. RTR-C:
   • Lan subnet of 10.1.11.254/24 on Eth0
   • Wan subnet of 22.22.22.22/30
   • IPSec tunnel to RTR A
   • NAT masquerade from lan to WAN
   • "Hairpin NAT" enabled (By default)
   • "Automatically open firewall and exclude from NAT" enabled

Here's the scenario:

1. RTR-A and RTR-C can ping eachother over the IPSec Tunnel using the route automatically created in Route Table 220
2. RTR-A and RTR-B can ping eachother over the switch. 
3. RTR-C cannot ping RTR-B. 

What i've tried (In no particular order):

• ip route add 10.10.1.0/24 via 22.22.22.22 dev eth1 proto zebra
• ip route add 10.1.1.0/24 via 22.22.22.22 dev eth1 proto static src 10.1.11.254 table 220
  • Did NOT work.
• Disabling all NAT on RTR-C 

I basically need to have traffic pass to/from RTR-C and RTR-B. Simple enough, right? 

Well aparently not for me!

How can i solve my problem?
