I have a simple requirement but all guides out there are generally for passing client certain traffic over the tunnel rather than just for SSH access back in to the router.
What I want is to have an IPSEC VPN tunnel between a Cisco IOS router (IR829 with Cellular connection) and my third-party router at head office (Mikrotik) which supports IPSEC (we use for other stuff).
I do not need any outbound traffic from the Cisco router to flow over the VPN, I purely want to use it as a way to access SSH from my head office to the Cisco router.
SSH is configured on the Cisco router and working fine from the LAN.
I have the basic IPSEC commands set up on the Cisco router, but its the routing and which interface to put it on etc.
Thanks!
