RADIUS end user IP attribute Vendor Specific for OKTA - Reporting Correct 2FA location

Hello,
I am trying to have OKTA report the correct IP from Sophos Firewall when we 2FA in.  What is Sophos Vendor Specific ID for Sophos UTM 9
They are asking the following to make this happen: Sophos UTM optional settings | Okta 
"In the Groups Response section, complete the following options:
  1. Select Include groups in RADIUS response.
  2. In the RADIUS attribute subsection, select 26-Vendor specific.
  3. In the Vendor Specific ID field, enter the numeric vendor ID code for your product (examples below):
    • Cisco ASA-Group-Policy: 3076
    • Citrix Group-Names: 3845
    • Fortinet Group-Name: 12356
    • Palo Alto User-Group: 25461
Any Help appreciated to get the correct reporting IP back to OKTA!
