I can't provide much detail because I don't get any reports or data from
varnishlog. No errors are reported. When I run "varnishadm backend.list", the
backend is reported as healthy. Plus, there's no issues with varnish
communicating with the backend when I visit the backend host from within the
varnish virtual machine. Everything works as intended when I run a web client
(curl or lynx) from the varnish vm terminal. The problem is varnish doesn't
communicate with the backend when I visit the backend host from outside the vm
on my host computer's web browser.
The setup is is this - two virtual machines running in vagrant and virtualbox
192.168.33.26 (apache box with hostname clas-test.myhost.pvt listening on port
84)
192.168.33.27 (clas-varnish.myhost.pvt)
>From default.vcl:
vcl 4.0;
import std;
import directors;
include "backends.vcl";
sub vcl_init {
new local_test = directors.round_robin();
local_test.add_backend(express_test);
}
sub vcl_recv {
if (server.hostname == "clas-test.hostname.pvt") {
set req.backend_hint = local_test.backend();
}
}
sub vcl_deliver {
if (obj.hits > 0) {
set resp.http.X-Cache = "HIT";
std.log("hitmiss:HIT");
} else {
set resp.http.X-Cache = "MISS";
std.log("hitmiss:MISS");
}
}
>From backends.vcl:
backend express_test {
.host = "192.168.33.26"; #ip of my host in its own virtual machine
.port = "84"; #port I have set in the virtual host on my host's virtual
machine
}
In /etc/varnish/varnish.params I have the VARNISH_LISTEN_PORT set to port 80
and VARNISH_LISTEN_ADDRESS commented out. Note, that when I set the address to
my backend ip, varnish won't start and I get this error:
bind(): Cannot assign requested address
[19743]: Error: Failed to open (any) accept sockets.
And yet when I run "varnishadm backend.list" with the listen address commented
out, the backend is reported as healthy.
Thanks again, all

You're not giving us any info that actually enables us to help you. What
doesn't work? What error messages do you get? What did you already try? What
were the results of these attempts? What is in the log?
Most important is:
What doesn't work? You've only stated that it doesn't work, not what is
actually happening when you've determined that it doesn't work.
