I have a two network interfaces machine, one is connected to the router and gets an automatic address via DHCP. The other has a static IP in a different subnet. I can ping both IP addresses, telnet to port 22 and see the "SSH prompt".. just fine. (trying them with switching the cable in my notebook)
Question: but when it comes to connecting to this machine via SSH I can only connect through the NIC that is connected via the router, not directly. It just timeouts when I try to connect directly. Why?
The firewall rules are the default, tried rebooting both sides, I only modified the "UseDNS to no" in the
sshd_config on the machine.
