Great ! it works

 

actually, I though my VS was OK because I had coded the VS Service Port option to 0 (meaning All ports), but I had forgotten to set the Protocol option to All Protocols too ! it was set to TCP

 

thanks a lot for your suggestion

    (hm, I see my previous update was recorded 3 times ... no idea why) last point still retated to ICMP ; when I issue a Ping from Internet towards an internal machine (associated to 2 VS, 1 per ISP link on the LC), the pings works but it is answered by the F5, not by the internal machine (I checked via TCPDUMP) If I do an SSH from the same Internet PC to the same internal machine thru the same VS, it works properly; The different with the previous case (ping from internal LAN towards Internet) is that, in this case, there is not SNAT defined, since the NAT is initialled performed on the destination This "problem" is not very annoying but, well, I was wondering if this was not related to Link Controller which is a GTM/LTM hybrid box ; Is there any debug function that allows to analyze which VS, pool, node, are selected by the F5 box when receiving a new request ? thanks in advance
