Packet Redirection on Windows

Question

We currently run windows on all of our machines due to software limitation.

Within this however, we are needing to redirect certain packets that come into an IP and Port to a different Port (same IP). We have software listening on the "Proxy Port".

This is achievable with IPTables on linux by doing something similar to:

iptables -t nat -I PREROUTING -p udp -d <DSTIP> --dport <DSTPORT> -m u32 --u32 '0>>22&0x3C@8=0xFFFFFFFF && 0>>22&0x3C@12=0x54536F75 && 0>>22&0x3C@16=0x72636520 && 0>>22&0x3C@20=0x456E6769 && 0>>22&0x3C@24=0x6E652051 && 0>>22&0x3C@28=0x75657279' -j REDIRECT --to-port <REDIRECT PORT>

This works great on linux and will redirect certain packets to our proxy software, however is it at all possible to do something such on windows without having to get a dedicated machine in-front of our windows machines?

I was thinking of writing something up with pcap.net but I'm guessing this will have to direct read from the NIC rather than windows?
