Hi Ron, I am sorry that this isn't a reply to your question, rather it is a request for info. I notice that you have a home network. I'd like to set one up but haven't been able to make sense of networking. Would you mind explaining it to me it simple terms? I have 3 i486s with 8Mb Ram and 212Mb hard drives with 3-com Ethernet cards. My main box has an Athlon 900 MHz processor, 384Mb Ram, 20 Gb hard drive and a RealTek card. I basically don't understand much about this. Thanks a lot.

The LM8.0 box does very basic IP masquerading for the other computers. I've had a wonderfully easy time with it to date, but now need to reach out to this community for help. When using NetMeeting on a W98 box, the other party can hear us OK, but we can't hear them. However, chat works fine. Same thing with MSN messenger: text chatting works fine, but "Talk" fails to connect. However, when that W98 box is directly connected to the cable modem (i.e. not through the Linux box), I can get sound both ways! Interestingly, 2 W98 boxes on the home network communicate great with each other - sound AND video - even successfully using the directory to find each other! So, the only thing that seems to stop NetMeeting and MSN Messenger sound working properly appears to be the Linux box. I have no firewalling in place (I plan to, once I figure all this out!). No Bastille running, only 1 rule in iptables - the one to get masquerading going with NAT. I also know that the ISP hasn't got a firewall in place, as I've checked with them (plus it works directly connected!). What am I missing? I assume that all packets in and out the cable modem are passed through untouched (other than IP address), so port handling and other communication details should be handled by the W98 boxes. Of course, the IP address NetMeeting shows behind LM8.0 as a 192.168 etc. address, but (not sure of nomenclature) I understood that iptables changes that when it does the masquerading? I've tried putting in port entries in /etc/services as per various obscure MS "support" pages I've managed to find. I've looked at the xinetd man page, but can't figure out what service I'd need to set up to enable this. And as I said, I thought that with masquerading, packets get passed through unless there's a rule saying not to. Any help, guidance, etc. would be greatly appreciated. I've been having a great time dusting off my old Unix skills, but I have to admit that TCP/IP networking is an area that's a black art to me. Keen to learn, though (which is the point, huh!)
