Hi,
Using OpenBSD 6.4 and I wanted to run some alias ip addresses on one of the
interfaces.
My question is, can I use a different network as an alias?
Example:
fw3# more hostname.bge0
inet 10.2.0.1 255.255.0.0
inet alias 10.2.1.1 255.255.255.255
inet alias 10.2.2.1 255.255.255.255
inet alias 10.2.4.1 255.255.255.255
inet alias 10.2.6.1 255.255.255.255
inet alias 172.17.11.1 255.255.255.255
I am having a problem pinging on the 172.17.11.0 network.
Ping 172.17.11.1
Responds, but nothing else on the network.
I saw one thing on the internet that said 'alias' has to be on the same
network, but this was not specific as far as age and what operating system.
To me a router, routes.
Any clarification or better way to handle this would be appreciated.
Thanks in advance,
Victor
Here is the routing table (with public ip and mac addresses changed or
obscured):
