Re: [TriLUG] Internet connection Sharing

[Chris Bullock]

Thanks for all the comments. I think that I have my problem fixed, I replaced the compaq nic with another SMC, (therefore running the same NIC on both interfaces). I was able to dhcp on the public if. However, after this I could ping but could not resolve DNS entries. Internet connection sharing builds shorewall which I am assuming blocks everything by default. I shutdown shorewall and with some help from a collegue changed the IPtables to allow. When I get some time to learn it, I will use IPtables instead of ICS for security.

I am tring to set up Internet connection sharing for my home network. Hardware, Using a Compaq deskpro with dual nics, one compaq and one smc1211. Have broadband coming in from my modem to eth0 which is my compaq card. eth1 (SMC)card is going to a Netgear 4-port 10mb hub which will hopefully feed my internal machines. I am using Mandrake 9.0 with all the updates. I have tried this twice on two different machines with the same result. I goto Mandrake Control Center and click Internet connection sharing and go through the steps, download the needed packages and so on, Configure my eth0 as the Internet interface and my eth1 as the LAN interface. All seems well until it finishes configuring. At this point my eth0 (Internet if) goes down. No light on the card or the modem. service network start will not bring up external interface. ifconfig does not show external but does show the internal. What file(s) does the Internet connection file use so maybe I can look at to see anything that stands out? Or can someone help?
Thanks in advance,
