Here's the situation: One Penium 60 (no PCI slots), and a couple of other PC's being a mixture of different pentiums 100+ mhz I used to have them on a 10mbps hub, but now I bought a 100mbps (not a switch) one. All of the sytems have a 10/100mbps nic, except for the Pentium60. I use the P60 as a firewall/gateway to the outside world. I wanted to save some money and not buy an extra 10/100mbps hub, so I put second nic in my main fileserver, which is always switched on anyway. I hooked it up to the 10mbps hub to let it connect to the P60-firewall. Still with me? So now the situation is as follows: P60: 1 isdn card connected to outside plus 1 nic 10mbps connected to 10mbps hub p500: 1 pci nic 100 mbps connected to 100mbsp hub and one nic 10 mbps connected to 10 mbps hub All others are connected to 100 mbps hub. P60 hub10 P500 hub100 ----------- ------- ----------- ------- ISP <----->| ISDN | |10mbps |<----->|192.168.2.1| |100mbps|<--> others |192.168.2.5|<----->| hub | |192.168.1.1|<---->| hub | (192.168.1.*) ----------- ------- ----------- ------- P60 does nothing but firewalling and gatewaying. (Very small HD) P500 does DNS, YPserver, Samba, mail etc. All others are just clients (win and SuSE) Now there are two problems: 1. I can see (ping, telnet etc) P500 from P60 and from all other PC's. I can also get to P60 from P500. But to everybody else P60 is invisible. 2. I cannot get ypclient to work on P60 (domain not bound), but it does work on other machines connected to the 100mbps hub. And a question: Is it true that with two hubs you have to use a different 3rd part of the ip-address? (eg .2.5 vs .1.5) I've tried the roaming the howto's, but to no avail. Can anybody point me in the right direction? I feel it would be a waste of money to go out and get a switch hub altough timewise... :-) <p>thanks for any help! keep up the good work Jeroen Verstegen jeroen@jota.nl http://www.jota.nl
