Ok. first message board post so be gentle.
also some times cant spell for jack. i know this.

Ok. here goes.
redhat 7.1, local net setup behind a nat router (sygate on nt box), cable modem. 2 nicks in linux box. eth0 is local ip (static). everthing works ok.
now along come bright idea and install 2nd nic. it works. tested as static first. no probs. i want to pull a ip from cable modem. after some digging and lots of learning i have found that i am getting the IP from modem. I found it in a file in /etc/dhcpc/dhcpd-eth1.info. so i am pulling ip info into this file but the eth1 nic will not start. what am i missing. id i take the ip addres and hard code it (i use linusconfig or network admin) it works fine, but that is not a good idea. so what am i missing?

Could you be a little more specific in describing your setup? Where does the cable modem fit in your network's configuration?
Like this:

Code:

Internet
   ^
   |
Cable Modem
   ^  
   |(DHCP)
   |
NT Router (performing NAT)
   ^              ^
   |(eth0,        |(static IP)
   |static IP)    |
Linux Box      Other Internal Boxen

Or:

Code:

External Network
   ^
   |
NT Router (performing NAT)
   ^              ^
   |(eth0,        |(static IP)
   |static IP)    |
   |           Other Internal Boxen
   |
Linux Box-->(via eth1, using DHCP)--> Cable Modem-->Internet
