Hi,
Anyone knows what needs to be done in order to play SMAC on a machine that has a masqueraded connection (NAT) thru a linuxbox?
What ports need to be forwarded, udp/tcp etc.
Thanks,
OE.

These are the lines that work for me. Please note that the IP address needs to match that of your machine on your network. To get this information, select Run from the Start menu, type "winipcfg", and look on the resulting dialog box. Then, change the address in these lines to match.

Enter the lines one by one (except the first, which is a comment) at the command prompt, then try a multiplayer game once all of the lines are entered - or, to enable this configuration, place them in a file executed every time your Linux box boots.

For me, this is /etc/rc.d/rc.local.

I'm not entirely sure if the first port forwarding line is necessary, but it doesn't seem to hurt anything.

If you don't have ipautofw, try looking at http://www.linux.org to find out where to get it.

ATTN FIRAXIS: I highly recommend posting this information permanently on the SMAC web site, as I'm sure it's a common query. I looked for a while, unsuccessfully, before I found the configuration that worked properly with DirectPlay.
