IIGS/Networking/Marinetti buffs please help (long!)

[Robert Flossmann <rfka01@gmx.de>]

Hi all,
I think I'm getting closer to TCP/IP networking my IIGS 
over Appletalk.
I'm asking for some Marinetti help here, but I'll 
describe my setup first.
Internet connection is: DSL modem-cum-router on 
192.168.178.1

A Performa 630 obtains it's TCP/IP-adress via DHCP and 
is 192.168.178.25. This machine runs IPNetRouter 
creating a MacIP interface on 192.168.2.1 and bridging 
those.

A MacPlus connected via appletalk can access the 
internet as is proven by running NSCA Telnet. I have 
setup MacIP as follows (TCP/IP-Panel): Adress is 
192.168.2.2, Obtain Adress manually, Router adress is 
192.168.2.1 (the adress given in IPNetRouter), and my 
DSL modem plus the two DNS servers of my provider as DNS 
server.
The procedure is: Mount the shared volume on the 
Performa, fire up Telnet, connect e.g. to syndicomm.com

Once I had this setup running I moved over to the IIGS 
running Marinetti and tried the same procedure:
Mount the shared volume of the Performa, Setup Marinetti 
as follows: Link layer is MacIP, Configure window: Local 
IP Adress 192.168.2.3, Gateway IP Adress: 192.168.2.1, 
DNS servers are: my router+one of the provider'S;
username and password are empty.

On hitting "Connect to network" in Marinetti, I get the 
messages "Registering named IP Adress, Looking for IP 
gateway"
When I try to telnet to, e.g. syndicomm.com, I get the 
"timed out" message.
Any parameters I have missed?

Thanks for staying with me that long,

Robert
