SureBackup - vLAB - subnetting

Post by abachiman » Apr 05, 2017 6:53 am

Hello,

we are trying to set up a SureBackup-Job for some of our productive VMs - now we are facing a challange:
our network is subnetted like this: 192.168.100.0 / 255.255.254.0 (/23) and the network settings within the vLABs vNIC regarding the masqueraded network will only accept subnets like /8 /16 /24 :(

in this case I can reach 192.168.100.10 but I can't reach 192.168.101.20 ... because the masquerading IP/network is just /24 (e.g. 192.168.200.x)

any ideas ?

many thanks
Andreas

Hi,

That's strange. The network settings should accept /23. Do you see any error message? Please elaborate.

Thank you

Hi,

sure: "Secified network mask does not match masquerade network address"

Settings:
  • Proxy appliance IP address in the isolated network [...]
    IP: 192.168.100.1
    Mask: 255.255.254.0
  • Masquerade network address for accessing virtual machines [...]
    IP: 10.10.3.D
=> the "3" indicates the vLAN ID of the Subnet (192.168.100.0/23)

Please specify 10.10.100.D instead. In this case VMs in the isolated network should get masquerade addresses from 10.10.100.1 - 10.10.101.254 pool.

Thanks
