There are different firewalls used at different customers. Sometimes, even
the admin of the customer has no knowledge or access to the firewalls. E.g.
a lot of public schools are routed thru the federal states network of their
state and the admin of the school doesn't have access to that network.
I didn't tested yet the pure tsnet commands. Perhaps I should create a test
program with that. Unfortunately often the admins are very impatient and
have no joy in testing different situations.
Thanks for your ideas

Do tsnet commands hit the same network blocks as put?

the customer which Antivirus/Firewall software is used?
