VCSA, vCenter Server Appliance 7 issue with gateway outside subnet - RESOLVED
Posting just in case someone else has the same problem as me.
Problem description: trying to add a gateway outside IP subnet fails*:
*my IP configuration (OVH failover IP - according to OVH failover IP configuration guide): IP address (failover IP): 53.X.Y.Z netmask: 255.255.255.255 gateway: 147.A.B.254 [where 147.A.B.C is an address of your dedicated server]
3. save file [:wq <enter> for vim] 4. ifdown eth0 ; ifup eth0 <enter> 5. Configuration is successfully saved. You can check it using: /opt/vmware/share/vami/vami_config_net or via DCUI or via vcenter server management (https://vcenter.my.domain:5480/#/ui/networking)
Do not attempt to change configuration through DCUI now - or it'll be overwritten (by no gateway at all).
