It looks like your robots cannot connect to the proxy or cannot get any
packets back from the proxy. Did you follow the HOWTO below? Did you
test client<->proxy and proxy<->server IP connectivity with ping
(specifying the right alias address as the source and destination IPs;
see Section 4.2)?

You will need to adjust the HOWTO a little to make work on Linux, but
all the major steps of setting up the network and DNS must be done for
the test to work.

While it is possible to simplify the workload (e.g., remove domain
names) but it is usually easier to start with defaults. PolyMix is a
realistic and, hence, complex test; running it by hand, especially for
the first time, is not trivial.

HTH,
