Yep.

Maybe.

Your FTP server is probably attempting a revers DNS lookup of the IP
address of your client.
Since your client is on a reserved Class A network (10.x.y.z) there should
*not* be a DNS "out there" that can offer an "authoritative" in-addr-arpa
range response in reverse lookup for hostname (FQDN). (More info on what I
say here is available in "DNS and BIND"
Try this:
Go to your FTP server on your private network and login as root.
As root, edit your file "/etc/hosts"
add an entry in "/etc/hosts" for your client stations that will be using
FTP to the server.
format:
# This is a comment as t starts with a "#"
#I.P.address.here hostname here althostname2 alt./alt.hostname3
#example.here.o.k. another.hostname and.yet.another and.one.more
10.0.0.1 mygateway.mydomain.com mygateway
10.0.0.2 brogus.mydomain.com mygateway
10.0.0.3 uhhh-huh-huh-huh.mydomain.com
10.0.0.4 myhostnameislongerthanyourhostname.mydomain.com
This should solve your problem for long wait tim for connects with
ftp. Please let us know if this works, or does not work for you
