Hi,

I am doing masquarading using my Debian machine running
Sarge. Earlier I was running the default kernel that comes with Woody (2.4.18-bf14
or something). Today I upgraded to the new kernel:
/var/log# apt-get -u
install kernel-image-2.4.22-1-686 kernel-doc-2.4.22 kernel-headers-2.4.22-1
kernel-pcmcia-modules-2.4.22-1-686 pcmcia-cs hotplug usbutils fxload hotplug-utils

And after this, I lost one of the NICs. I have two NICs, one is 192.168.0.1
connected to the ADSL moden, and the other is 192.168.0.2 connected to the
internal LAN. So when I booted into the new kernel, the second NIC RLT8139
was not detected. But when I did pppoeconf, it listed only 1 NIC and asked
if I had more which were not detected. I said Yes, and it hen allowed me
to install the module for the RLT NIC. And after that it reported 2 NICs
fine.

So after configuring ppp0, I could browse the net, but my internal
LAN machine can't. I can't even ping that machine. I am running the same
iptables rules as before. Here is what I get:
/var/log# ping 192.168.0.10

PING 192.168.0.10 (192.168.0.10): 56 data bytes
ping: sendto: Operation

ping: sendto:

--- 192.168.0.10 ping statistics ---
2 packets transmitted, 0 packets received,
100% packet loss


I get this evenif I do "/etc/initd/iptables clear".




Here is my interfaces file:

Any idea what could
have gone wrong during installation of thsi new kernel? More information
