Hello all, It seems there is a problem with 'net' expression with IPv6. Tested on both 3.6.2 and 3.7.0 beta.
The packet to match: 12:39:52.476697 3ffe:2620:1:ff88::2.33124 > 2002:c1a6:317::1.33441: udp 12 [hlim 1] However, 'tcpdump net 2002::/16' does not show this. Works: tcpdump net 2002:c1a6:317::/48 tcpdump net 2002:c1a6:0::/36 Doesn't work: tcpdump net 2002:c1a6::/32 tcpdump net 2002::/16 So, it'd seem that all prefixlengths >32 work but shorter don't. Test capture file attached. -- Pekka Savola "Tell me of difficulties surmounted, Netcore Oy not those you stumble over and fall" Systems. Networks. Security. -- Robert Jordan: A Crown of Swords
