Regarding traffic from node to Internet

Hi Team,

We have an issue where we are trying to access internet from one of node which is behind LTM. Unfortunately this is not working. Below is the diagram of our network

Internet <<-- Firewall <<-- LTM <<--switch <<-- node

We are using LTM as router to direct all default traffic to Firewall so it can be forwarded to internet. But while trying to accomplish this we are seeing LTM dropping traffic. While in wireshark logs I am seeing traffic is natted to its own subnet self ip created on LTM (i.e. backend IP of LTM) and not to front end IP of LTM (which is pointing to firewall).

Please suggest if any changes is reqd?

We have created Forwarding VS and there is static route pointing to firewall.

Thanks.
