If you are using a SNAT disabled catch-all virtual server that has no default pool, the server-side connection might reset.
Connection is reset.
This occurs with the following configurations: 1- Catch all virtual (destination network 0.0.0.0/0:0). 2- SNAT disabled. 3- No default pool. Also this happens only before the classification cache is trained, which requires at least two flows.
There are many workarounds: 1- Train srDB by sending two or more flows, and the third flow will not see a reset. 2- Use a virtual server with SNAT enabled (or automap). 3- Add a default pool to the virtual server.
Server-side connection is now correctly set when using a SNAT disabled catch-all virtual server that has no default pool.
