Re: GRE(not over IPSec) tunnel troubleshooting

Hello,

 

Is it a pass through GRE or a GRE tunneling on the firewall itself? 

 

For pass through GRE use d"debug flow basic " with proper flow filters.

 

For Gre generic tunneling, please use " debug gt gre " option

 

Hope it helps your requirement.

 

Regards

Looking through the ScreenOS 6.3 Concepts and Examples guide, the only mention of using GRE is when bound to tunnel interfaces on the device.  So I believe you only can use this with GRE over IPSEC as a result.
