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. 
telneting to ssh port works, but SSH not
