Hi all! I know there is a lot in this e-mail, but please read through the whole
thing. Here, I need to give some background, then describe the problem and list
out some configuration data...
I've been using Miami v3.0 for a while (yes, I'm registered) to connect to my
dial-up ISP.
I want to do something different now with Miami, and most of it is working, but
part is not.
I now have a new ISP, a cable modem service. Attached to my cable modem is a
cable router (linksys). Attached to the cable router are 2 of my PCs, one is a
Win98 box, the other Linux. These systems work great to connect to each other
and the internet using the cable router as their gateway.
Anyway, my amiga, I decided, I would like to have disconnected from my old
dial-up ISP and instead, be hosted by my linux box (which now has it's own
internet connection through the cable router). (i.e., not connecting the Amiga
to the cable router directly, but using PPP to connect the Amiga to the Linux
box which would run a PPP server.
So, now, I have a PPP server running on my linux box. I have the linux box
connected to my Amiga (Amiga 2000 '040 with O.S. 3.9, Miami V 3.0) box via
serial ports (no modems). One side has a null modem, the other side does not,
and communication is done with 4-wire telephone wire (pins 2, 3, 7, and 20).
Anyway, I was very successful in this endeavor. :) Using Miami, I am able to
connect my Amiga via PPP to my PPP server, the linux box! It really worked.
They can now ping each other. They can communicate with each other, transfer
files, etc.
[ I am *not* using DHCP on the Linux server to serve IPs. Nor is the Amiga
using DHCP to get the IP. ]
[ I've assigned the Amiga the IP address (192.168.1.4) that the linux box
(192.168.1.2) wants the amiga to have --set through the linux PPP server's
options file as you'll see below--, and have given the amiga a hostname (not
fully qualified). Miami seems to get and set the Amiga's IP properly. ]
Things look good so far... but...
I can communicate fully between the linux box and the amiga, however, the amiga
cannot see *past* thelinux box. The linux box uses the IP address(192.168.1.1)
of the Cable Router box as it's gateway tothe Internet and the other machine on
my local lan.
I need to somehow inform Miami what to use as it's gateway. In other TCP/IP
implementations, there's usually a section for entering a gateway or router IP.
But for serial PPP in Miami, I have not found a way to enter the gateway. Any
thoughts? Below is some more information and some things I tried.
(** Note that When I would connect my Amiga to my old *dial-up* ISP, the gateway
is set automatically from the ISP. I did not have to set anything on my Amiga
directly in Miami. Miami got it somehow from the ISP. ** Not so in the case
described here...)
My Linux box's IP is 192.168.1.2 (behind the cable router)
My Amiga box's IP is 192.168.1.4
My cable router box's IP is 192.168.1.1
On the Amiga side, here is the output from ifconfig:
lo0: flags=8009<up.loopback,multicast>mtu=2108
inet 127.0.0.1 netmask FF000000
HW Type: Loopback
mi0: flags=8011<up,pointtopoint, multicast>mtu=296
inet 192.168.1.4 --> 192.168.1.2 netmask FFFFFF00
HW Type: other
The Linux box's PPP serving options are:
asyncmap 0
local
xonxoff
lock
+pap
-chap
38400
192.168.1.2:192.168.1.4 # sets the gateway and ip address for dial-in
Using the above, I can communicate back and forth between my linux box and the
amiga, no problem, but my amiga cannot see outside the linux box (i.e., it
cannot see the cable router or anything else on the local lan.)
Now, if I change the last line in the linux box's PPP options to:
192.168.1.1:192.168.1.4 # sets the gateway and ip address for dial-in
Where now the gateway for PPP is set to the cable router IP, and restart the PPP
server on the linux box, the amiga can still communicate with the linux box (as
before), but can *NOW* also ping the cable router! That's a slight improvement.
However, the amiga can not ping anything else on my local lan, nor can it see
the Internet... It can only see it's PPP server host (the linux box) and the
cable router.
So, doing as above, and now seeing the cable router, still does not seem to
configure the Amiga (through Miami) to use the cable router as a gateway.
Here is the linux box's PPP server log file when I have the linux box as the
gateway and have the Amiga connect to it:
Using 192.168.1.2:192.168.1.4 in PPP's options file (PPP server -- LINUX)
192.168.1.4 is the amiga box connecting in. This works, but
no gateway.

Here is the linux box's PPP server log file when I have the cable rotuer as the
gateway and have the Amiga connect to it:
Using 192.168.1.1:192.168.1.4 in PPP's options file (PPP server -- LINUX)
but setting the cable router to be the gateway for ppp.
192.168.1.4 is the amiga box connecting in. This works, but
again, no gateway

Note that all the machines on the current lan including the cable router can see
each other just fine, and all the machines on the current lan use the cable
router as the gateway to the Internet.
It's just the Amiga that cannot see past what I've described above.
Thanks so much for any sugggestions any of you can offer. Again, I think it's
mainly being able to set the gateway through Miami that's holding this up from
working.
Oh, and does Miami 3.2b add the gateway setting option?
