Gateway problem

Post by Eric CHOLE » Mon, 07 Jul 1997 04:00:00

I am trying to setup a FreeBSD system to act as a gateway to the
My assigned IP address block is Following advice from
ISP, I have subnetted this block as follows:  netmask  Internet lucifer cisco netmask  DMZ-1 lucifer netmask  DMZ-2 lucifer eden

'cisco' is the router to my ISP.
'Lucifer' is the gateway system, running FreeBSD 2.2.1.
It has 3 NICs with the following config: netmask netmask netmask
    defaultrouter =
    gateway = yes

'Eden' is a machine on DMZ-2 where I which to run my web server.
Its config is: netmask
    defaultrouter =

From Lucifer I can ping the whole world.
From Eden I can ping any of Lucifer's addresses, but nothing else :
'ping cisco' fails. 'traceroute cisco' shows that it's trying to
use the default gateway, but goes no further.

I'm new to this stuff, in case I'm not making sense.



1. Problem with TCP/IP: Gateway problem??

I set up TCP/IP on a machine, gave it a unique IP address, but now
I can't telnet to it from outside.
I can telnet from it TO outside [and by outside I just mean another
machine on the network]

all machines are running Linux 2.0.27, same setup, same cards

I can telnet between any of the other machines, BUT I CAN"T telnet from
the old machines to the new one [THe new one is just the one I installed

Could this be a problem with Gateway? I just set it to the IP address of
the machine.
