IPSec VPN between Cisco and Mikrotik

RouterOS General
1

Hi Guys,
I am new to Mikrotik and struggling doing IPSec VPN between Cisco ASA and Mikrotik RouterOS v6.7. The main problem is that both Sides Site A and Site B have same LAN subnet 192.168.0.0/19.

Below is the scenario :

Site A :

LAN IP : 192.168.0.0/19
Tunnel IP : 94.200.X.Y
Device : Cisco ASA 5515-X

Site B: 192.168.0.0/19
Tunnel IP : 83.111.A.B
Device : Mikrotik RouterOS v6.7

Please suggest the configuration at Site B where we are using Mikrotik.

Regards
Harish

Don’t think you can have the same LAN subnet on both ends…

maybe you can ip-ip them and bridge the two segments, but you cannot ipsec tunnel two same subnets
