We have a Cisco router with SSH configured. If I am physically inside the LAN, I can SSH to it via the private IP 192.168.1.1, or alternatively via its WAN IP (provided by the DHCP of our ISP).
However I can't connect remotely using that WAN IP at all if I am not in the office LAN.
Why does it do that? Someone says NAT problem but I can't relate it.
All suggestions are welcomed, thank you.
