Not quite sure what you mean here... the linux box is 192.168.1.2 and I (through the
ppp
server options file) have given the amiga an IP still in the same subnet (amiga IP =
192.168.1.4) as the linux box. So, how do I give the PPP interface on the linux box
another IP to be used for PPP? I shouldn't be using it's normal ethernet one? Must
PPP
be actively running for me to assign this address? I figured it would all be taken
care
of by the gateway:client line in /etc/ppp/options.
A question for you and for Soyeb (who just wrote me too). WHen I have the
gateway:client line read 192.168.1.2:192.168.1.4 doesn't that indicate to the Amiga
that
the gateway for the Amiga to use is 192.168.1.2 and that it's own address is
192.168.1.4
? OK, then I guess IP forwarding would come in, so that I can really see the router
192.168.1.1
But, where do I tell Miami to use the 192.168.1.1 (cable router) as the gateway as
opposed to some other device on my lan... or does IP forwarding tell the linux box to
take the amiga packets and forward the ones not for the linux box over to the linux
box's gateway/router (the cable router, 192.168.1.1) ?
OK, but what about the case when I tried having the gateway:client line in
/etc/ppp/options look like 192.168.1.1:192.168.1.4 , where the first part is *not* the
linux box, but rather the cable router? In this case, I can (without IP forwarding)
ping both the linux box and the cable router from the Amiga, but cannot ping further
within or outside the lan from the Amiga. The fact that IP forwarding is not present,
yet I can still reach the router in some form still seems odd, right?
Next question...
> same host). For kernel 2.2.x you can enable this by:
> echo "1" >/proc/sys/net/ipv4/ip_forward
Doing the echo sets a flag so that bootup will always initiate IP forwarding? Or must
I
do this after each boot (i.e., have a script run that line each time on the linux
server
at boot time?)
Thanks again!
