AmiTCP: multiple interfaces?

[leofoe]

Is it possible to run AmiTCP 4.2 with 2 adapters at a time? I have an A1200 connected to my router. Then I have the A1200 connected to an A2000 through a parallel cable, via the magplip device (TCP/IP). I would like to connect to the internet from the A2000 through the A1200 and the router. Both machines have OS3.9 installed.

At least it's possible with AmiTCP/IP Genesis. I don't remember if I've used it with older AmiTCP's, but I'd guess it's possible. And if it isn't for some reason, you have OS3.9 which comes with Genesis, so why wouldn't you use it?

Genesis allows multiple interfaces, but there is no routing between them. AFAIK MiamiDx is the only IP stack which allows routing.

AmiTCP can use multiple interfaces and route between them - ie act as a gateway, but it cant do NAT, which nowadays often is what people mean when they talk about routing.

Is it possible to shed some more light on this? If I use startnet, I can reference only 1 interface. How do I configure and start the extra interface?

[leofoe]

OK. I managed to get both interfaces run simultaniously with bootpconfig. With the A1200 I can connect to the internet and to the A2000. With the A2000 however I only can connect to the A1200, not the internet.  :-?

Probably there is no routing between the two interfaces. You need a TCP/IP stack which supports routing.

Sorry my mistake. I take it you have configured routing on the A1200's TCP/IP stack. Perhaps it would help if we could see your IP configuration for each interface.

A1200:
AmiTCP.config: GATEWAY=YES
interface1: bootpconfig Orinoco IP=192.168.1.15 GW=192.168.1.1 (this is my router)
interface2: bootpconfig magplip1 IP=192.168.1.17 DEST=192.168.1.16

A2000:
bootpconfig magplip0 IP=192.168.1.16 GW=192.168.1.17

[motorollin]

I think the two interfaces on the A1200 have to be on different networks, otherwise nothing will be routed.

E.g.

A1200:
AmiTCP.config: GATEWAY=YES
interface1: bootpconfig Orinoco IP=192.168.1.2 GW=192.168.1.1
interface2: bootpconfig magplip1 IP=192.168.2.1 DEST=192.168.1.2

A2000:
bootpconfig magplip0 IP=192.168.2.2 GW=192.168.2.1

Subnet mask on all of them should be 255.255.255.0

--EDIT - various mistakes :roll:

@motorollin:
This gives the following bootpconfig error on interface2 magplip1:
SIOCAFADDR "object exists"

[motorollin]

Hmmm not sure about that as I've never used AmiTCP. Maybe a duplicate IP address on the network?

Don't know if this helps at all:

Thanks for the drawing.
The duplicate is probably the DEST of the magplip1 and the IP of the Orinoco. That's the only possiblity.
