Inquiry

Which address should I set for "Access List" of vCore, a global IP address or private IP address?

When using the Internet as underlayNetwork, use a global IP address.
- This function assumes that it is used together with static IP address service offered by your provider.
- When using this function, registering the "Permit" setting will reject all the accesses from non-registered IP address. Note that accesses from all vClient devices may be rejected if you accidentally register a private IP address.

Inquiry

Is it possible to set the same IP address for different destination User Networks?

Even if a part of IP address of plural desination UserNetworks are the same, that has no effect on the service.
However, please note that the service does not work normally if the completely same addresses are binded to vCore.

[Available]
-Destination UserNetwork A 172.16.0.0/17
-Destination UserNetwork B 172.16.0.1/32
> Although Destination UserNetwork B is the host address in the Destination UserNetwork A, the service works normally.

[Available]
-Destination UserNetwork A 172.16.0.0/17
-Destination UserNetwork B 172.16.0.0/18
> Although Destination UserNetwork B is the network address within the Destination UserNetwork A, the service works normally.

[Not available]
-Destination UserNetwork A 172.16.0.0/17
-Destination UserNetwork B 172.16.0.0/17
> If both the destination UserNetwork and subnet mask are the same, service will NOT work normally.

Inquiry

When trying to add a destination UserNetwork, the message "The address is incorrect" is displayed.

The four addresses below cannot be registered as a destination UserNetwork and therefore the message "The address is incorrect" is displayed.
-0.0.0.0/0
-10.0.0.0/8
-172.16.0.0/12
-192.168.0.0/16

Note that this error also occurs and the address cannot be registered when (1) the host address is set to other than "/32," (2) there is an incorrect relation between the network address and subnet, (3) a global IP address is entered, and (4) wrong IP address is entered (like, extra "0" is included).

[Examples]
 (1)192.168.0.1/24 (correct address: 192.168.0.1/32)
 (2)192.168.1.64/24 (correct address: 192.168.1.64/26)
 (3)200.200.200.1/32 (global IP addresses cannot be registered)
 (4)192.168.00.1/32 (correct address: 192.168.0.1/32)

If you would like to use the address range mentioned above, please divide the segment in two, and make two destination addresses.

[Examples]
* When you would like to use 10.0.0.0/8(10.0.0.1 ~ 10.255.255.254)
 > 10.0.0.0/9 and 10.128.0.0/9

* When you would like to use 172.16.0.0/12(172.16.0.1 ~ 172.31.255.254)
 > 172.16.0.0/13 and 172.24.0.0/13

* When you would like to use 192.168.0.0/16(192.168.0.1 ~ 192.168.255.254)
 > 192.168.0.0/17 and 192.168.128.0/17
