Bug #14055

Updated by Marcos M about 1 year ago

Tested on pfSense+ 23.01. 

 Test: 
 # Configure a GIF tunnel (IPv6 local/remote tunnel address) and / interface for use in policy routing. 
 # Create download and upload limiters (used weighted queues with the WF2Q+ scheduler). 
 # Create a firewall rule on LAN - specify the GIF as the gateway and the limiter queues for the In / Out pipe. 
 # Send traffic over the GIF tunnel via the policy based rule. 

 Result: 
 For both IPv4 and IPv6 traffic (used ICMP as test), the packet enters the @gif0@ interface and is then dropped. The system logs show the following when the packet is dropped: 
 <pre> 
 Feb 28 19:16:32  	 kernel  		 gif0: loop detected 
 </pre>
