SP3

I started running a public sp3 server today. It’s a small side-project I’ve hacked together over the last couple weeks to make it easier for people to play with packet spoofing. The server works similarly to a public proxy, but with the trade-off that while it won’t send high-volumes of traffic, it will allow you to send arbitrary IPv4 packets from any source you want.

There are a few fun applications that need this capability that I’ve been thinking of: helping with NAT holepunching of TCP connections; characterizing firewall routing policies; and for cover traffic in circumvention protocols. I think there are others as well, so I wanted to start running a server to see what people come up with.

The code is on github.
