update: looks like it was a the dallas3 level3 routers, not playing nice with icmp.
We should be good to go now *crosses fingers*

If not, this type of issue can sometimes be worked around by lowering the mtu on your system. It'll be less efficient, but it will also force the packets to be smaller.
On windows, this is done with something like:

netsh interface ipv4 set subinterface "Local Area Connection 1" mtu=1300 store=persistent

This would make the packets split at 1260 instead of 1460 bytes, but it really shouldn't be necessary. 1460 byte packets should work fine.
