fw monitor output

[Norbert_Papirny]

Hi All,

I need some help with fw monitor output.  (R80.20 gaia T47)

Our GRE/SIP  communication doesn't work, and as you can see below, the last captured packet was stopped in pre-outbound (o4) chain position. It is the tunnel-inside traffic.

We have bidirectional rules between peers without NAT.

Could you please somebody explain what caused this behavior? 

Here is also the relevant wireshark capture:

There are many articles/ cheat sheets ,etc. about how fw monitor is working, but i cant find any information about the output interpretation...
