[Fwd: 3C905B question]

[Erik D. Fields]

Not sure if this is the right place or not, but any help or pointers
would be greatly appreciated.

I am attempting to setup my ADSL modem.  My configuration before
had only 1 3C905B card in my system, which connected to my
local network (192.168....).  The /etc/conf.modules file had the line:
alias eth0 3c59x

With the network configuration I can hit my 192 network without a
problem.  My machine (acting as the gateway) has an ip address of
192.168.1.1.  In order to set up my ADSL modem, I needed to add
another network card into the system, to communicate directly with
the modem. Therefore, I installed another card (also a 3C905B).
Using linuxconf, I added another adapter to the system, which put
the following line into the /etc/conf.modules file:
alias eth1 3c59x

The eth1 ip address is set to 172.16.1.2

Now when I reboot I can no longer hit the 192.168 network.
Is there something special I need to do to get the 3Com NICs to
work together?  Or, am I missing something on the Linux network
configuration?  I have gone through all the documentation and searched
the web, but cannot determine where a conflict might be.


NOTE:  I am running Redhat 6.0 (2.2.5.15), with the following config:

PS:  This machine servers as the gateway to my home network
and also is running ip-masquerading and dhcpd (server).
