Windows SMB communication uses IP port 445, and every properly configured corporate firewall should already be blocking that port to prevent any SMB communication from LAN to WAN (this has been an industry-standard firewall policy recommendation for many years).

Specifies the type of protocols and the order of connection for passthru authentication sessions. The default is to use NetBIOS, if that fails then try to connect using native SMB/port 445. Specify either a single protocol type or a comma delimited list with a primary and secondary protocol type.

SMB Relay Attack is a type of attack which relies on NTLM Version 2 authentication that is normally used in most companies.

First we will need to manually set up a port forwarding rule, using netsh, on "Client 1". We now have a rule set up which will forward traffic arriving on 10.0.0.129:5678 to 10.1.1.3:445. For this to work Impacket's PsExec will need to connect to a custom port, this is not supported out-of-the box but we can easily edit the python source.
