Unable to connect using tftp other than over openvpn

I am trying to configure a tftp server and am having difficulty connecting
to it from a tftp client

vi /etc/xinetd.d/tftp
service tftp
{
        socket_type             = dgram
        protocol                = udp
        wait                    = yes
        user                    = root
        server                  = /usr/sbin/in.tftpd
        server_args             = -s /tftpboot
        disable                 = no
        per_source              = 11
        cps                     = 100 2
        flags                   = IPv4
        log_type                = FILE /var/log/tftp.log
}

>From client
tftp -v 203.89.001.001 -c get cfg000b82024216 Connected to 203.89.001.001
(203.89.001.001), port 69 getting from 203.89.001.001:cfg000b82024216 to
cfg000b82024216 [netascii] Transfer timed out.

The server is running open vpn and the client is connected to it. I can
successfully connect using tftp over openvpn so it's not a permissions
issue.
tftp -v 10.8.0.1 -c get cfg000b82024216
Connected to 10.8.0.1 (10.8.0.1), port 69 getting from
10.8.0.1:cfg000b82024216 to cfg000b82024216 [netascii] Received 890 bytes in
4.4 seconds [1611 bit/s]

If I add the bind directive then I still can't connect over the public ip
(and I can no longer connect over the vpn either):
        bind                    = 203.89.001.001

If I stop the openvpn service I still cannot connect over the public ip
address.

If I flush the firewall rules I still cannot connect over the public ip
address.

Any help appreciated
