I tried dropping the MTU several times without success. I then swtiched the DTU to go over our FioS conenction instead of the T1 connection to the internet and the stalled lines went away. Both my T1 and FioS conenctions are connected to the same physical switch on the outside of the network so it was just a matter of changing the live IP on the DTU. I'm assuming the stalled lines had to do more with bandwidth/latency than anything else.
