/sbin/ifconfig eth0:10 xx.xx.xxx.221 netmask 255.255.255.224 down
on box1, and on box2:
/sbin/ifconfig eth0:10 xx.xx.xxx.221 netmask 255.255.255.224 up
Both boxes are located on the same network.
After migrating, I'm able to ping the ip from both servers, I notice it responds 10x faster on box2 than on box1 so it seems like that went ok. However I'm not able to ping the ip from outside of the network.
eth0 on both boxes are the public ips, the alias is also a public ip.
When I move the ip back to box1, I'm able to ping it outside of the network without any issue.
I am also able to ping the public ip (eth0) on box2 just fine, so it doesn't appear to be a firewall issue.
Do the routers need time to update the new one to point to the new MAC address?
What am I missing?
