I have latest MikroTik RouterOS and need help to setup two IPSec Tunnels in chain for communication.
SiteA <> SiteB <> SiteC
---- Tunnel1 ---- Tunnel2
SiteA - LAN: 192.168.1.0/24, ISP WAN: 184.108.40.206/30
SiteB - LAN: 192.168.2.0/24, ISP WAN: 220.127.116.11/30
SiteC - LAN: 192.168.3.0/24, ISP WAN: 18.104.22.168/30
SiteB is "central one/Headquarters" with latest stable MikroTik RouterOS.
Each Site has one local LAN subnet. IPSec tunnel from SiteA to SiteB (Tunnel1) is configured and working (over public Internet). Also between SiteB and SiteC (Tunnel2).
All IP>Routes are configured.
I need help to configure RouterOS on SiteB (HQ) to allow devices from SiteA to communicate to SiteC. So this packages (ICMP, TCP) should go through both IPSec Tunnels.
How to achieve this? How to configure IPSec>Policies in that case?
Also, if possible to have without implementation of NAT
