The LAN setup is File Server RTL8139 LAN card, IP address 10.0.0.3 120 GB Hard Drive, and SAMBA to share the drives contents
Options Server (Two ethernet cards) Intel Onboard card, 100B, IP adress 10.0.0.2 (disengaged, as I dont use it) PCI 4 port internal switch (acts as a network card too, RTL8139), IP address 10.0.0.1 56K External modem, which is attached /dev/ttyS0 and a WVDIAL setup to drive it DHCPD which allocates 10.0.0.4 to 10.0.0.10/255.255.255.0 (keeps the two windows clients, and any guest machines, happy) IPTables firewall and NAT script ( http://morizot.net/firewall/ ) so that the server can dish out internet access via the 56k modem >From the Options Server (10.0.0.1) if I start ppp0 (WVDIAL) and ping my ISPs DNS server (203.97.33.14) it tries to ping from 10.0.0.1, not 203.isp.dhcp.address and the end result? Destination host unreachable. Destination host unreachable. Destination host unreachable. etc etc etc ad infinitum. Now, here's the way I got it to go... Kinda rudimentary but effective ifconfig eth0 down /etc/rc.d/rc.firewall wvdial ifconfig eth0 up This, as you can imagine, is a royal pain in the ass if the modem should get disconnected while I'm 400+ kms from home, and wife knows little/nothing about linux to correct the issue... it's a big toll call talking her through the many steps... ----- Original Message ----- From: "Volker Kuhlmann" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, October 23, 2003 9:31 AM Subject: Re: Networking issue > > if you've just got an ethernet card 90% of the time, which is attached to > > a single closed subnet, and occasionally dial up via a modem, then you > > really should not assign the default route to your ethernet card.
