Well, I'd say that VPN is the most obvious solution for this problem, but since you haven't done that already, I assume you aren't doing this above the radar, or without network competent administrators. An SSH tunnel is feasible as long as the client side doesn't need to use the work IP for the protocol to function. Maybe if you gave some details on this 'license server' we could get a better idea on what we're working on. Is this plugging into something like LM Server? -----Original Message----- From: Brent Gregersen [mailto:gregerse@xxxxxxxxxxxxxxxxxxxx] Sent: Wednesday, October 22, 2003 10:08 AM To: netfilter@xxxxxxxxxxxxxxxxxxx Subject: work ip address at home I need help with the following setup. I have one machine at home that gets an IP address (say 1.2.3.4) by DHCP from an ISP. However, I would like applications on my home machine to think it has the ip address of my machine at work (say 4.3.2.1). I would then like to forward a specific port of my home machine to my work machine, and then forward that to a license server at work. Thus, application thinks I'm at work, license server thinks Im at work, but Im really sitting comfortably in my own home. Is this possible? Should this be done with netfilter/iptables or should I be looking at another option? If it is possible, I could get some extra work done at home, without having to use certain graphics intensive programs over a tunneled X connection to my work machine(which is extreamly slow).
