Tftp traffic not passing

Not sure what the deal is, and I can't seam to figure it out. Im starting to pull my hair out.
The Setup…

internet---pfsense ---192.168.255.253/30---cisco router---172.16.0.0/20---internal
|
| tftp 172.16.10.1
|
openvpn 10.20.30.0/24

This is what i am trying to do.
I need to be able to pull files off the TFTP server from the OpenVPN session, but I can't. I can see the openvpn session request the file on the tftp server and it (tftp Server) start to resound. On pfsense I only see the request for the file, but never a response from the tftp server. Then the session timeouts with a timeout error.

included are a tcp dump showing a trace route to the tftp server then the file request.

Any help would be greatly appreciated.

To add more juice to the issue.

I am current RDPed into a machine from an OpenVPN session. That same machine is running solarwinds TFTP server. I have disabled the firewall on that machine, and I am unable to pull TFTP files from that machine through the OpenVPN Session. This seems odd since I’m able to pull all other services but TFTP..

Please help?
