I’ve just committed an update to Snort_inline’s SVN. It brings it to the Snort 184.108.40.206 level. It supports both IPv4 and IPv6 on IPQ and NFQ. I have not been able to test IPFW on IPv6, so I don’t think that will work currently.
This update removes the libdnet dependency and replaces it with libnet 1.1. To be able to send ICMPv6 unreachable packets you will need the libnet 1.1 patch I wrote a while ago. You can find that here. Get the latest Snort_inline by checking out SVN:
Consider the code to be of beta quality for now, so be careful with it. Please report any problems with it!
Again, a big thank you to NitroSecurity for funding this work!
