What does this specification mean? I asked the one who gave me this but I did not understand.

Vlan 22/23

a) Does 22/23 mean that 23 subnets have been allocated

b) The forward slash in 10.3/11.4 has something to do with CIDR or does it mean that has been mapped to

c) When using VPN to connect to I can access internet but on I do not.

    Your question needs more context. Please add details like a network diagram or detail explanation of how the network devices are connected, the network device models, and the network device configurations. Without more information, we can only speculate or guess, which is off-topic here.

1 Answer 1


I undestand it as:

  • VLAN 22 -
  • VLAN 23 -

I.E. the IP address is in VLAN 22 and the IP address is in VLAN 23.

Regarding the VPN we cannot tell you what happens without knowing much more details about the network, the configuration of the VPN gateway, etc...
