What subnet is the internal server on vs the external client subnet?
The quickest blind-shot way to fix this is usually to set "Source Address Translation" to "Automap" on the LTM virtual server.

- You can use a comment on my original post to reply. Have you set Source Address Translation to Automap yet? You need address translation enabled because otherwise, you need to have routing between the two subnets. The routing has to be such that the traffic is all flowing through the F5, and never directly between the client and the server.
- ashish_sharma43I was used source add translation to automap, but no luck

There's definitely still a route issue here. Can you compare the setup for Fusion (should be similar to workstation) to your network setup? https://devcentral.f5.com/s/articles/f5-developer-edition-installing-big-ip-on-vmware-fusion-8

Anyone can help to fix this
