Maybe a networking / ssh guru can explain this one: ssh connections from my home net thru a Dlink router work to a Mandrake box, but not to an FC4 box.
- I have an FC4 box 'phoenix' and a Mandrake box 'insecure' attached to the Internet (outside my office firewall).
- I can ssh to phoenix and insecure w/no problem from my Win 2k PC on the same exposed subnet and from within my office firewall.
- From my HOME network I can ssh into insecure but NOT into phoenix from a variety of machines (win2k, XP, FC4). My home LAN is behind a DLink firewall.
Phoenix is running an iptables firewall, but I can prove that it's accepting the ssh connections by logging the 'accept' rule, and in fact it doesn't matter if I turn the firewall off altogether. I've also turned off SELinux with no improvement (except that my iptables logging stops)
My hosts.allow file on phoenix is allowing all incoming ssh (sshd:ALL), but when I turn on debugging in sshd it logs no messages when connecting from boxes behind my DLink f/w.
The connection from my home LAN to phoenix seems to be getting lost between iptables and sshd. Can anyone tell me what's happening here? In fact, if anyone wants to try ssh to 216.214.99.171 and let me know if they get a login prompt, I'd appreciate it!
