We plan on implementing greater security measures at the EECS network border in the near future. Specifically, ingress and egress filtering similar to what is described in RFC2827 / BCP38.

This filtering is designed to block two types of traffic:
* traffic leaving EECS, which has a source IP outside of valid EECS IP space
* traffic entering EECS, which has a source IP within EECS IP space

This will prevent spoofed IP traffic from entering or leaving the department network.

If your work or research relies on spoofed IP packets, in the ingress or egress directions, please contact us at help@eecs.berkeley.edu so that we can work with you to find a solution.
