Hi, I've recently installed FreeBSD 2.2.5 on my ThinkPad 560, and now I'm trying to get the network interfaces set up properly. I have been running ppp over a PCMCIA modem successfully for some time now, but I need to add support for ethernet access to my local LAN. I have a 3Com 3C589D PCMCIA ethernet card installed in the machine, and pccardd seems to recognize it properly as device ep0. I'd like to be able to use the ethernet card in three different situations. First, I'd like to be able to use it as the only network interface on the machine to access a stand-alone LAN (of about 5 nodes). In this case I assume that I need the following set in my rc.conf file: pccard_enable="YES" pccard_mem="DEFAULT" pccard_ifconfig="ep0" tcp_extensions="YES" ifconfig_lo0="inet 127.0.0.1" ifconfig_ep0="inet 10.20.30.1 netmask 0xffffffff" # IP address on local LAN defaultrouter="NO" router_enable="YES" Do these look right? In this case should I set the network_interfaces parameter like this network_interfaces="lo0 ep0" or should I leave out 'ep0'? It seems that when I have 'ep0' in this line the ifconfig is performed before pccardd is run, so the ifconfig fails. But, when I leave 'ep0' out of this line, pccardd doesn't configure that interface for me when it recognizes the card. What am I missing here? Second, I'd like to be able to use the ethernet card to access the local LAN while using ppp to access the rest of the Internet. For this I need to allow two different IP addresses - the one on my LAN and the one assigned dynamically by my ISP. I guess that I can define one in the ifconfig_ep0 line of rc.conf, and ppp will negotiate the other with the ISP, but will this all work together? Will I need to statically define the other nodes in my LAN? Again, do I put the 'ep0' device in my network_interfaces line? Will my local 'routed' conflict with ppp's routing of packets? Finally, I'd like to be able to use the ethernet card to connect directly to a real ethernet drop on a live network when one is available. Same questions about when/how the interface gets configured apply here. I guess that in this scenario I'll need to set defaultrouter to the gateway as well. Any help that you can offer me would be appreciated.
