now we talk about ftp service in core:
request: ftpd service installed. Core uses vsftp in default module, but we can change it as best we.
on routers nodes we choose ip_forward how in first lab1 and we add an access-list by shell vtysh:
conf term
'q'
access-list filter permit any # don't use it in production
end
write memory #
quit
execute those cmd on each router.
test service as picture shows.
