Hi Sadorect,
how do you test the functionality?
To troubleshoot it would help to run a tcpdump on the system to look after incoming (and perhaps outgoing traffic).
tcpdump -e -nnni 0.0:nnnp -s 0 -c 100 host
The trace should show the incoming packets (including MAC addresses and VLAN information) and the related forwarded traffic (including MAC addresses and VLAN information as well).
What is the output of the following commands, please:
tmsh list net self one-line
tmsh list net route one-line
tmsh list ltm virtual one-line
Can you ping the router specified as next hop for your default gateway?
Thanks, Stephan
