We can't really provide instructions or support for setting something like this up, but the default port used by LsPush is 9524. LsPush will only work with direct server connection if inbound traffic over this port is allowed on your Lansweeper server. You can configure your own, custom LsPush port as well, in the Service Options section of Configuration\Server Options. If you do, don't forget that a restart of the Lansweeper Server service is required for this change to take effect.
