Unable to connect to ssh server
I am having issues connecting to a remote host via ssh and I suspect that this is due to some security restrictions on their side. I can't be sure of that so I just come and ask for your advice.
The remote host is configured to allow only some specific IP addresses to connect. I have to connect to this server from two different places :
- my university room, where I have a fixed public IP address
- my parent's, where I connect with a local IP address, via a NAT router (a "box" provided by my ISP). The NAT router has a fixed public IP address.
I asked the administrator to allow access for the two IPs (the fixed public IP I have when I am in my uni room, and the fixed public IP of my parent's NAT router).
I have no problem connecting from my room at university, but I can't connect from my parent's (The server doesn't even respond when I ping it from there).
I have no problem accessing other SSH servers (without IP restrictions) from my parent's.
So I thought maybe this comes from the fact that my computer has a private IP address that is different from the NAT's public address which I gave to the sysadmin, and this could cause trouble at somepoint.
Anyone has a more precise idea so as to where this comes from ? And how I can solve the problem and connect to this ssh server from behind my NAT router ?
Thanks in advance for your help,
