I'm trying to build a "vpn" from my home network to my work network. So far I've managed to ge the ppp link (tuneled over ssh through socks) between a mchine at work, and a machine at home. I've added routes to the work network on the mahcine at home, and added routes back to the ppp machine at home from my default router machien for bothe the work network numbers, and the (192.168.x.x) addresses of bpth ends of the ppp link. So, I can access any machien at home from the machine at work that originates the ppp link, and I can access that amchien from any machine on my network at home. So far so good, however the remaining stumbling block is getting beyond thta machine at work. The packets it puts on the woek network still have a source address of 192.168.x.x. And of course amchiens at work don't have nay idea how to get packets back to that network. I need the machine at work to do something like "reverse NAT", thta is I need for all the packets that it puts on the work network to have a src address of thta machine, and I need it to be able to translate the reply packets back to 192,168.x.x. Can I do this with netgraph or soemthing? -- "They that would give up essential liberty for temporary safety deserve neither liberty nor safety." -- Benjamin Franklin
