Hi Sadorect,
as "listener" you have network virtual servers in IP forwarding mode?
The easiest approach would be to create a wildcard virtual server of type network 0.0.0.0/0:any for all protocols in mode "forwarding IP" with SNAT AutoMap enabled and listening on all VLANs.
Please make sure to enable SNAT for
all protocols in case you want to PING as well.
You will find this configuration option via WebUI in System››Configuration:Local Traffic:General (option "SNAT Packet Forwarding" modified to "All Traffic").
Alternatively you can use tmsh as well:
tmsh modify sys db snat.anyipprotocol value enable
tmsh save sys config
Thanks, Stephan
