Troubleshooting Tip: Source/destination country is shown as 'Reserved' on Forward Traffic logs

Below is given a Forward Traffic log in order to understand better the issue:

date=2025-08-08 time=10:45:30 id=7178532351538969304 itime=2025-08-08 10:45:30 euid=3 epid=3 dsteuid=3 dstepid=101 logflag=1 logver=704085164 type=traffic subtype=forward level=notice action=timeout policyid=23

10:45:30 itime_t=4231865792 devname=<Name_of_the_device>

In the log above, 'srccountry' and 'dstcountry' are shown as 'Reserved'. This is the expected behavior. Both source and destination IP addresses are private IP addresses. Since they are private IP addresses, they do not belong in any country. For this reason, the source and destination country is shown as 'Reserved'. 

Also any IP address which is part of below subnets (private IP address), will be shown as reserved.

• 10.0.0.0 - 10.255.255.255: (10.0.0.0/8) 
   
• 172.16.0.0 - 172.31.255.255: (172.16.0.0/12)
   
• 192.168.0.0 - 192.168.255.255: (192.168.0.0/16)
