What can I put in place to allow my computers to answer a request without gateway

[florian.laloge]

Hello guys, In my company, we want to put a cisco router to create a new network. In fact, we have a kind of server, and he will go through the router and ask to every computer ( they collect data from weather...) to collect his data. Our collecters are all around our state, they have an IP, but for the moment, they dont have gateway. 

That's why i'm asking what can i put in place on the cisco router to tell them " when you are asking something, answer to x.x.x.x, no matter if you dont have gateway ". In fact, if there isnt a solution to put on the router, we'll have to go to every computer and put manually a gateway...its time loss.. (We cant take theses computers from distance ).

More clearly, i want to put a thing on the routeur saying to our computers  ' hey answer to me '. As i ve said, the server ( which will ask to our clients), is in our office, and he'll pass trough the router to ask to them.

For the moment, when i do a simulation and i put a gateway, it works, but when i try to delete it ( as i want to be in real ) it doesnt work

Hope i was clear,

Sorry for my english, it's not my mother language.

Have a nice day,

Regards

The computer either needs a default gateway or a route in its route table for the specific network. One option would be to add a route using a batch file. You could put the following in a .bat file and send to the end user to run on each computer.

route -p add 10.1.1.0 mask 255.255.255.0 192.168.1.1

This would add a persistent route to the 10.1.1.x network using a gateway of 192.168.1.1. This is assuming a Windows computer.

Thank you for answering so fast! In fact, im in training in this company, and my boss gave me this project, and for that solution he told me there was something to add on the router to do what we need. ( but my job was to search so he didnt gave me the answer)

But the problem is that the collecters are more like small markers, tags, i dont know a windows is running on em... So thats why i wanted to know what to put on the router. 

Im gonna search again and again, and wait for other answers, but if i cant put anything on the router, and if a windows is running on em, then i'll use yr solution.

Oh, moreover, if it can help, the router is quite old, its a cisco 2851. 

Thank for answering brandon

Regards.

The only thing I can think of to add on the router would be a DHCP scope that includes a default gateway option. It sounds like the devices currently have static IP addresses configured? Moving to DHCP would certainly solve the problem, but would also include changing the config on each machine.

Yes but they need to be static. In fact, our server dont know their IP, he uses an IP for each for example 192.168.1.2 for one collecter 192.168.1.2 for one other etc... And i've put NAT on the router, and the routeur make the translation beetween the server destination adress and the collecter address. 

So yes they need to be in static

thank you for yr answers
