I need some help to shed me some lights over an IPsec tunneling. Here I will explain on my current setup.
Site A <-------IPSEC------> Site B (HUB) <------IPSEC------> Site C 10.1.1.1/24 10.2.2.1/24 10.3.3.1/24
Tunneling from Site A to Site B & Site B to Site C are working fine. However Site A is not able to reach Site C directly and vice versa.
On Site A the phase 2 entry: Local: LAN Subnet Nat / Binat: None Remote: Network (10.2.2.1/24)
On Site C the phase 2 entry: Local: LAN Subnet Nat / Binat: None Remote: Network (10.2.2.1/24)
On Site B there are 2 IPSec Tunnels:
Site A Phase 2 entry: Local: LAN Subnet Nat: None Remote: Network (10.1.1.1/24)
Site C Phase 2 entry: Local: LAN Subnet Nat: None Remote: Networ (10.3.3.1/24)
Note: FYI we do not have the access to Site C. Therefore any adjustment only could be made on Site A and Site B.
Kindly let me know if you may require any other information. Thank you in advance.
