--lTNgmc+xy1dBmNvC Content-Type: text/plain; charset=us-ascii I'm using freebsd as a multicast router here, and I need to be able to allow igmp requests from a network so viewers can join a group, but block transmission of multicast packets in general. ipfw only knows about tcp and udp, and from looking at the code and include files, it looks like the protocol specification interface is very limited. You need to be able to actually specify the protocol by number if the name isn't known (e.g. rsvp is 42, I believe, and I'm sure there are others). -- Alan Batie ------ What goes up, must come down. batie@aahz.jf.intel.com \ / Ask any system administrator. +1 503-264-8844 (voice) \ / --unknown D0 D2 39 0E 02 34 D6 B4 \/ 5A 41 21 8F 23 5F 08 9D --lTNgmc+xy1dBmNvC Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: 2.6.2 iQCVAwUBNAdOOBCfrckvDwdpAQHovwP+P0Rmx3KafQlktO7NxWHYZOSfagv0nVAk oZXBp7YKZjnJ2dKkK+DJlqrpF1JwRJMbrigVHjjGCSq2+Ny6R6dLtQpoIkEUoA32 CKEhRPOeRVjgmGCImaosqBV1tJEeZkpYzu5MsgDu3pq5FzZAJsW007B2P7USu6M+ wcpfv0e8AnE= =1xNE -----END PGP SIGNATURE----- --lTNgmc+xy1dBmNvC--
