rcm3700 ip problem

Hello everybody
I'm facing a problem in a rcm3700 module.
This module works as a server in port 23 .
We can connect to this in module when it has the ip 192.168.0.xxx but never when it has
the ip 10.179.237.xxx.
We have try with subnet 255.0.0.0 and 255.255.255.0. but nothing happens.
We can ping it but we cannot connect to port 23.
Because the net 10.xxx.xxx.xxx is a b type we must configure it in another way ?
Best regards to all
Theodore Politis.

Have you tried 255.255.0.0 for the mask? It is quite common to see this on 10.x.x.x networks. e same on all devices on a given subnet so check what your PC is set for on the 10.x.x.x network.

I agree. Also, you are using port 23 which is typically used by telnet. Any chance you have a telnet server active in your product? If not, anything else that could also be using port 23?

Provide the ip address,netmask,gateway for both the rabbit and the
machine you're trying to connect from.

Is this a direct connection in some way, or is a router involved?
