I have installed the system, I have edited the sysctl.conf file. I have ipv4 forwarding enabled. I will try to be brief here.
My host network is 192.168.0.0
I have 192.168.0.54 assigned to eth0
virbr0 has an ip address of 192.168.122.1
I never installed or even know what virbr0 is.
I can ping 192.168.0.54 just fine.
I can ping 192.168.122.1 just fine.
I cannot ping my gateway at 192.168.0.1
I have no external network connectivity.
Before I installed openvz on this system, I could get out just fine.
here is my sysctl.conf file:
net.ipv4.ip_forward = 1
net.ipv4.conf.default.proxy_arp = 0
net.ipv4.conf.all.rp_filter = 1
net.ipv4.conf.default.accept_source_route = 0
net.ipv4.tcp.syncookies = 1
net.ipv4.conf.default.send_redirects = 1
net.ipv4.conf.all.send_redirects = 0
after reboot cat /proc/sys/net/ipv4/ip_forward returns a 1.
I'm not a brain surgeon. What am I missing? A default route somewhere? Everything on the host side looks fine. Why would I all of a sudden lose my ability to see my local network after installing openvz? Does the virbr0 interface take over all routing?
Any help is much appreciated.
