Overview and Notes
To enhance security, PORTERS lets you restrict which IP addresses can access the business screens.
For example, by allowing access only from IP addresses used within your company, you can prevent access from outside third parties.
[Notes]
- This feature restricts access to the business screens after login; it does not restrict login itself. Therefore, even if access is restricted by this feature, a record of the login will still appear in the login history.
- PORTERS' IP Address Restriction works by registering the IP addresses that are allowed to access the system.
- You can register single IPv4 addresses as well as addresses in CIDR format.
- IPv6 is not supported.
- If you enable IP Address Restriction without registering any IP addresses, no users will be able to access the system.
Before changing the IP Address Restriction status, be sure to register your IP addresses first. - If your company plans any system maintenance, please check whether it will involve a change of IP address.
If an IP address change is expected, be sure to register the new IP address in advance.
If you do not register it beforehand, all users will lose access as soon as your company's IP address changes.
- Even when IP Address Restriction is enabled, configuring Remote Access lets specific users issue a passcode and access the system remotely.
To prepare for the unexpected situation where all users are locked out due to IP Address Restriction, we recommend enabling Remote Access for system administrator users.
- The IP Address Restriction screen displays the IP addresses that have been registered, as well as the IP addresses of any users currently using Remote Access. The latter are shown as "Remote Access" in the list.
Opening the Settings Screen
You can open the IP Address Restriction settings screen from the settings (gear icon) menu at the top right of the screen, under "IP Address Restriction."
Adding IP Addresses and Enabling/Disabling
If you have already registered IP addresses that are allowed access, a list of the registered IP addresses will be displayed.
By default, the restriction status is set to "Disabled."
Adding an IP Address
To add an IP address that should be allowed access, click the "+Add" button at the top of the screen.
Enter the IP address you want to allow access from, then save.
The "Current IP Address" field shows the IP address that the user performing the operation is currently accessing from. If you want to register this address, copy and paste it, then save.
You can freely enter any text in "Memo," such as "Yamada's home" or "Osaka branch office."
Enabling/Disabling
Registering an IP address alone does not yet apply any restriction.
After registering the IP addresses that are allowed access, click the "Enable/Disable" button at the top of the screen, select "Enabled," and save to apply the restriction.
*Be sure to register the allowed IP addresses before enabling the restriction.
*To prepare for the situation where all users are locked out due to IP Address Restriction, we recommend enabling Remote Access for system administrator users.
The restriction status will change to "Enabled."
While a user is using Remote Access, that user's IP address is automatically added to the list and shown as "Remote Access."
Once Remote Access ends (for example, due to logout), the entry is automatically removed from the list.
Force Logout
Even if you change the Enabled/Disabled setting for IP Address Restriction, it will not apply to users who are already logged in.
If you enable IP Address Restriction and want to apply it to all users immediately by logging them out, click the "Forced Logout" button.
Filtering
You can filter the list by entering search terms in "IP Address," "Memo," or "Remote Access."
To return to the default view, either delete the entered conditions directly or click "Clear all conditions."
- IP Address / Memo: Partial-match search using free text
- Remote Access: Click the magnifying glass button and choose from "OFF" or "ON"
Number of Items Displayed / Pagination
Using the dropdown at the top right of the screen, you can choose to display 20, 50, or 100 items per page (the default is 100).
If the number of items exceeds the display limit for one page, the results will be paginated.
Reference: What Is an IP Address?
When users access PORTERS, they connect to the internet to reach the system.
There is a network in which each PC, server, and other device is interconnected like a web, and when browsing something like a job listing site, your PC
connects to a server somewhere and loads the data stored there.
An IP address is an identification number assigned to each of these network devices—much like an address on the network.
There are two types of IP addresses—global IP addresses and private IP addresses—and PORTERS' settings use global IP addresses.
A global IP address is an IP address used for internet connections; each one is unique and never duplicated anywhere in the world.
Global IP addresses also come in two forms: dynamic IP addresses, which change periodically, and static (fixed) IP addresses, which do not change.
A static IP address is required to use PORTERS' IP Address Restriction feature.
Please check with your in-house system administrator or network administrator to confirm how your company's IP addresses are configured.
Private IP addresses, also known as local IP addresses, are addresses used within private networks—such as an internal company LAN—that cannot be accessed from outside.
They cannot be used in PORTERS' settings.
