I'm having a problem running an win app through a ip masq gateway box, and was pointed to ipautofw. I tried to contact the author, but it bounced. I am running red hat 5.2 w/ stock 2.0.36 kernel. Since I will have to recompile my kernel to use this, I have a basic question to ask, but would also like to know if you think this will fix my problem based on the tcpdump output below. Ok, the basic and probably stupid question is, will this support multiple win machines through the ip masq box, all running this app and talking to the same server? This is the whole point of the exercise, and if this is not going to do it, I'll stop right here. I think the answer is yes, but want to make sure. Now my specific problem has me stumped. I can successfully ping, telnet and ftp to the server from the pc through the ip masq gateway. For the telnet and ftp, I just get as far as the login prompts since I don't have accounts, but I believe this is enough to show that the masqerading and routing is setup correctly. When I use the app, ( basically a front end to an oracle database I believe), it just times out with a variety of socket errors. Can you tell from this dump output is ipautofw will solve my problem? I don't fully understand this output, but I don't see the server trying to respond to s different port than the client is actually using. I'm really desperate to get this working. tia charles additional info: client install added service ih2000 2005/tcp to the services file It is using sql/net oracle7. I believe this is just straight tcp/ip server is aix v4 Here is the tcpdump output, (tcpdump -i ppp0 -l -n > /tmp/tcpdump.out) first showing a successful ping, telnet and ftp, then the failed attempt to use the client, followed by a successful ping.
