NIC 2 cannot accept incoming telnets !

[fonso]

Here you are the explain of my problem :

I have tested the two NICs separatly and the work well, but,
when I install the two NICs, I have problems :


This is the configuration with the NIC 1 only installed :
---------------------------------------------------------

With this configuration, it works fine !.
The router is configured in the 192.168.1.10 IP, and redirect the incoming telnets at
the 192.168.1.100 IP.
The SCO is the 192.168.1.100 IP.

I was connected from a remote site trougth the Internet (from the 213.99.166.81 IP).

The ethernet adapter works ok!:
The fea adapter (ADAPTER NOT FOUND) is the second NIC. Now its not installed.

Now, I have supressed the NIC 1, and installed only the NIC 2, with a new configuration :
-----------------------------------------------------------------------------------------
The router is configured in the 10.0.0.1 IP and redirect the incoming telnets at
the 10.0.0.61.
The SCO is configured in the 10.0.0.61 IP

With this configuration, it works fine too!.

The ethernet adapter was Not Found is the NIC 1 and it is not present.
The fea adapter is the NIC 2, it is alone, and it is the only adapter installed.

With this configuration, all works ok!.



!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

But NOW, HERE IS THE PROBLEM !!!!!!!!!!!!

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I install the two NICs in the system.
The NIC who was the 10.0.0.61 works well with my local network,
but the NIC who was the 192.168.1.100 cannot accept the incoming telnets
from the internet. I need to accept incoming telnets from the internet
in the NIC 192.168.1.100.

The router was configured in the 10.0.0.1 IP, and redirect the incoming
calls to the 192.168.1.100 IP (the second NIC in the SCO).

This is the information of the SCO :

I have do a "route add default 10.0.0.1"

The problem NOW iw when I need to connect from the Internet, it not respawn.

Whats wrong ?. What can I do ?.
How I can accept incoming telnet calls from the internet in
the 192.168.1.100 IP (second NIC) of my SCO ?

I presume you have some kind of device between your SCO box and the internet doing network address translation? What is it? Can you connect from that device to your SCO box using telnet? Can you ping the system from the internet, or is it only telnet that is not working?

I suspect you may have to set your default route to the 192.168.1.100 address, because that's where any traffic for the 'rest of the world' will need to go. Do a route add 10.0.0.0 10.0.0.1 so that your local traffic still goes to your local gateway. Annihilannic.
