curl failed because connection refused on vm

hi all

i have two ubuntu virtual machines on a window host.

win host: 10.1.1.176 vm1: 10.1.1.177 running the fstack helloworld, the firewall is disabled vm2: 10.1.1.172 not taken over by fstack, can connect to www.bing.com normally

now i'm trying to curl vm1 from vm2, and got connection refused

the window host and two vms are in the same segment 10.1.1.* and connects to the same router.

vm1 ping vm1 -> failed vm2/host ping vm1 -> succeed

and vm2 traceroute vm1 prints a lot of *

traceroute to 10.1.1.177 (10.1.1.177), 30 hops max, 60 byte packets
 1  * * *
 2  * * *
 3  * * *

currently, i set the ipaddr of both veth0 (by using command ifconfig) and f-stack-0 (in f-stack.conf) as 10.1.1.213. and then, i set the gateway of f-stack-0 as 10.1.1.1, which is the same as the one of my host machine and another virtual machine. i'm not sure this way is correct.
