Date: 22 Mar 1996 04:28:35 GMT Organization: University of Michigan Lines: 24 Message-ID: <4ita9j$14r@lastactionhero.rs.itd.umich.edu> NNTP-Posting-Host: stargate.rs.itd.umich.edu NNTP-Posting-User: 14125 X-Newsreader: TIN [version 1.2 PL2] I have a local e-net that I want to have internet access. The problem is that I have access to only a single *real* IP number (via PPP). I know that there are firewall/proxy packages out there (SOCKS?) that in theory should allow me to access the outside world through the NetBSD machine that has the PPP line. The problem is that I would have to access it through proxy interfaces. I noticed that linux has something called "IP masquerading". From what I have gathered this is what I want. It allows a single host with one IP to serve many hosts with *private* IP numbers (10.x.x.x etc.) It does this by changing the packet address on the packets it routes, so that the outside world can only see the gateway IP address. This seems like the ideal solution since it doesn't require that a special proxy enabled client be used. Is there an equivalent to this for NetBSD? Thanks Todd Ferris tferris@umich.edu
