Hallo together,
I am trying to…
laptop (LAN 192.168.88.2) → Mikrotik haplite (Router1 - LAN 192.168.88.1 WAN 10.10.0.2 )–>Vodafone BOX (Router 2 LAN 10.10.0.1 WAN 31.99.2.1) → Internet → (Router3) telekom router (WAN -dyndns Firma.vpn.de LAN 192.168.0.1) → (Router2) Kerio control (WAN 192.168.0.100 LAN 192.168.33.0/24)–> Server 192.168.33.100
i try to Connect to Kerio vpn with the Mikrotik, but it doesnt work. if i use my vpn from windows it works fine. but i need serveral devices to connect so the router should do it.
I try also to find a howto but all of these didnt help me. Does anybody has a howto or know a link…
I think my problem is the NAT and my unawareness of ipsec
