    10. 

  10. <br>I have made a lot of changes in the core-agent-linux code in order to 
    11. 

  11. fix minor bugs which emerged during manual testing as well as improve 
    12. 

  12. the overall logic robustness.
    13. 

  13. <br>Unfortunately, I am still having some troubles in debugging why the 
    14. 

  14. incoming packes in sys-net are not reaching the next hop (sys-firewall, 
    15. 

  15. 10.137.0.6). Tcpdump and nft trace monitor are totally silent in 
    16. 

  16. sys-firewall, which I guess confirms the 0 counter as shown in the 
    17. 

  17. "rules" screenshot (which is of sys-net). Tracing the packets seems to 
    18. 

  18. show a succesful opeartion:
    19. 

  19. <br>1) The incoming packet is accepted
    20. 

  20. <br>2) The packet is forwarded to the vif72.0 interface succesfully
    21. 

  21. <br>
    22. 

  22. <br>The trace is the result of the "ssh <a class="moz-txt-link-abbreviated" href="mailto:test@192.168.137.128">test@192.168.137.128</a>" command, which 
    23. 

  23. is the ip of ens6 in sys-net
    24. 

  24. <br>
    25. 

  25. <br>I will continue to try to debug the problem tomorrow, but still I am not 
    26. 

  26. really sure what to check more...
