Packets loss but no drops - VM Series, AWS, GWLB

L0 Member

i have a server sending traffic on 443 through GWLB to my Palos and out to the internet


The logs all say 'aged out'


Packet capture reveals the SYN arriving wearing GENEVE, being de-encapsulated, source NATed and forwarded out Untrust


The SYN/ACK arrives on Untrust, but there is no record of the firewall forwarding these packets to GWLB and client - they just vanish


The drops packet capture is empty


This worked previously, but we had to rebuild Panorama after a disaster and a colleague has been 'hardening' the appliances


I suspect an error has been introduced but for the life of me I can't work out what it might be

Feel free to provide the output for the global counters once you have them.
