Re: [ts-7000] RE: ts-7800 how do I make 4 (at least 2) identical network stacks?

"He has two legacy boxes with the same fixed IPs that can't be changed."  

Exactly.   I actually have four legacy boxes with the address 1.1.1.101. I want a C program or programs for the ts-7800 that can individually talk to each of the legacy devices through the 4 ports of the ts-7800.  

So I want to know if on the ts-7800 can I set up 4 IP stacks/SOCK/iptables/whatever  so that I can have a 4 different networks, lets call them A, B, C, and D, all on the same ts-7800. 

so I should be able to have a c program of the sort:

talk_to_legacy_device -n[A|B|C|D] -i[1.1.1.101] -m"message" 

where 

on all 4 networks, I have established that my node is 1.1.1.200.   

when I use talk_to_legacy_device, the -n parameter lets the c program know which of the 4 networks I want to send the message out on, and then also has a listener on that same network for the response from 1.1.1.101.   

eventually I will have 4 background processes all listening on the four different networks, for a communication from their respective 1.1.1.101 legacy system, and signal a command program to format a response and have only that one background process send the reply.   

So can this arrangement be set up on the ts-7800 or not???

He has two legacy boxes with the same fixed IPs that can't be changed. I had the same problem on a recent contract.

No you don't want that. You want to go to Amazon and
order some TCP/IP book :-)
