[zeromq-dev] Fwd: Beginner question with respect to zmq_proxy

[Nishant Mittal]

Hi All,
I have a zmq_proxy device with ROUTER and DEALER in the front and back
(attached code broker.c)
router binds to tcp://*:5551 and dealer binds to tcp://*:6551
the client connects to router with a REQ socket as tcp://nishant:5551 and
worker connects to dealer with a REP socket as tcp://nishant:6551 where
nishant is the hostname of the machine..

the above works fine

however, if I move the client to another machine.. the worker sees the
request but the client doesn't get any response.. what am I doing wrong?

thanks in advance for your help.
