SSH connection through the firewall with no ports open
PC1- 10.128.14.12 (linux)local network
PC2- 10.248.12.100 (linux) in DMZ PC1 can ping PC2, no ports are forwarded so I can't SSH on each other. Workaround (but silly) is - PC3- 10.248.12.2 (Win2k3) port 3389 open on firewall (Cisco PIX) PC1 -> RDP -> PC3 -> Putty -> PC2 With this configuration I am not able to use tunnel VNC from PC2(KVM) to PC1. I have admin rights for PC1 and PC2, cannot install anything on PC3 Is there any available solution to this? Eg. use Putty to forward the ports etc... Please don't advise anything like "tell your admin to open the ports", I am neither hacker or networking expert, just need to access my KVM server and dealing with silly people here. Thanks |
If I understand you correctly the putty session is between PC3 and PC2, both of which are in the DMZ. RDP is only giving you the remote desktop and is not forwarding or tunneling ports. Any SSH tunneling would be between PC3 and PC2 so no use to you.
Perhaps a temporary solution would be to have the VNC session run over port 3389 as you know its open? |
Are VPN ports PC2<->PC1 open?
|
does PC3 have an ssh server running on it? If so you could do an ssh bridge

on PC2 have you tried having an ssh server running on port 3389 since the pix allows it to pc3 it might have a general rule allowing access to the rdp port

do you have a list of the rules on the pix?
