[libvirt-users] Problem in bridged networking

Hello, I am facing some problems in bridged networking. I have successfully created a bridge br0 and added a virtual machine to it. Now the address of virtual machine is 10.1.3.31. I am able to connect to this virtual machine by another computer on same network. The virtual machine is hosting a simple python http server on port 8000, while some other service is running on port 80 When I try his on my main server : # curl 10.1.3.31:80 Response I get is this : * Rebuilt URL to: 10.1.3.31:80/ * Hostname was NOT found in DNS cache * Trying 10.1.3.31... * Connected to 10.1.3.31 (10.1.3.31) port 80 (#0) * Recv failure: Connection reset by peer * Closing connection 0 curl: (56) Recv failure: Connection reset by peer But when I try this on any other port # curl 10.1.3.31:8000 Response I get is this: * Rebuilt URL to: 10.1.3.31:8000/ * Hostname was NOT found in DNS cache * Trying 10.1.3.31... * connect to 10.1.3.31 port 8000 failed: Connection timed out * Failed to connect to 10.1.3.31 port 8000: Connection timed out * Closing connection 0 curl: (7) Failed to connect to 10.1.3.31 port 8000: Connection timed out Output of iptables -L: Chain INPUT (policy ACCEPT) target prot opt source destination ACCEPT tcp -- anywhere anywhere tcp dpt:ftp ACCEPT tcp -- anywhere anywhere tcp dpt:8000 ACCEPT tcp -- anywhere anywhere tcp dpt:1022 Chain FORWARD (policy DROP) target prot opt source destination ACCEPT all -- anywhere 10.0.0.0/16 state RELATED,ESTABLISHED ACCEPT tcp -- anywhere 10.0.2.4 tcp dpt:http-alt ACCEPT tcp -- anywhere 10.0.2.4 tcp dpt:1883 ACCEPT tcp -- anywhere 10.0.2.4 tcp dpt:1883 TCPMSS tcp -- anywhere anywhere tcp flags:SYN,RST/SYN TCPMSS clamp to PMTU Chain OUTPUT (policy ACCEPT) target prot opt source destination Output of ifconfig: br0 Link encap:Ethernet HWaddr 00:1a:64:c1:31:2e inet addr:10.1.3.33 Bcast:10.1.3.255 Mask:255.255.255.0 inet6 addr: fe80::21a:64ff:fec1:312e/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1578351 errors:0 dropped:15619 overruns:0 frame:0 TX packets:1327458 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:198829729 (198.8 MB) TX bytes:346380435 (346.3 MB) eth1 Link encap:Ethernet HWaddr 00:1a:64:c1:31:2e UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:7429105 errors:0 dropped:31238 overruns:0 frame:0 TX packets:7684361 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:782334104 (782.3 MB) TX bytes:2221485458 (2.2 GB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:87278 errors:0 dropped:0 overruns:0 frame:0 TX packets:87278 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:12350508 (12.3 MB) TX bytes:12350508 (12.3 MB) vnet0 Link encap:Ethernet HWaddr fe:54:00:14:0e:98 inet6 addr: fe80::fc54:ff:fe14:e98/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:6411332 errors:0 dropped:0 overruns:0 frame:0 TX packets:6277721 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:1909595770 (1.9 GB) TX bytes:656284846 (656.2 MB) Output of cat /etc/network/interfaces : auto lo iface lo inet loopback auto eth1 iface eth1 inet static address 10.1.3.33 netmask 255.255.255.0 gateway 10.1.3.1 dns-nameservers 192.168.2.11 192.168.2.12 auto br0 iface br0 inet static address 10.1.3.33 netmask 255.255.255.0 gateway 10.1.3.1 dns-nameservers 192.168.2.11 192.168.2.12 bridge_ports eth1 bridge_stp off bridge_maxwait 5 dns-nameservers 192.168.2.11 192.168.2.12
