I have a machine with linux 1.2.5, and two ethernet cards. It works as a
router for my lab. eth0 is for the internal network, and eth1 for external.
I will consider 4 machines: lab -> machine in my internal network.
router -> the linux router box
outside -> some machines outside the lab connected
by network.
(not all machines, some work and some
don't)
dial -> machine outside the lab and outside the
router domain connected by modem. (ppp)
It's a bit complicated, so i will explain by examples and replies from the
machine.
Everything I will explain happens with finger, telnet and ftp. Of couse, the
error messages are different.
From lab to router -> works
From router to lab -> works
From lab to outside -> works
From outside to lab -> works
From lab to dial -> works
From dial to lab -> works
From router to outside -> don't work
error message: connection closed by foreign host (telnet)
From outside to router -> work
From router to dial -> work
From dial to router -> don't work
error message: connection closed by foreign host (telnet)
Any ideas? Thanks in advance
