[44net] Packet loss through UCSD?

Folks: I just brought my ampr host back online after moving to a new facility. My initial configuration is to enable internet <-> amprnet connectivity. So I have all traffic in both incoming and outgoing directions routed IPIP'd via UCSD. The host is Linux Fedora based (will be transitioning to CentOS sometime...) and I used the guidelines set on the wiki. One unexpected thing is packet loss. I am seeing very slow performance using this approach and rather poor packet loss. Are there any issues or QoS policies implemented on the amprnet router at UCSD? Thank you, Assi kk7kx/4x1kx

AMPRNet host: kk7kx.ampr.org (icmp & http only for now) Internet host: phantom.kiloxray.com (hosts kk7kx)
