Question about multicast forwarding
Hi, I have the following networks: --- | | | | iptv device (172.16.113.2) FreeBSD (re0:172.16.113.8) | (re1:172.16.112.2) | PCs The iptv device which sends to multicast 224.0.3.2, I want my PCs to receive multicast packets and let clients watch TV. Should I use net/mrouted or use pf can do that? Would anyone tell me how to do? Thanks. Cheers, Dave. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
RE: Multicast Forwarding
Loren We managed to get it working on the 23rd of July. Mrouted does forward multicast packets as long as at least two machines join a multicast session. The one channel on one of our routers were stuffed so we replaced the router and it worked fine from there. Albert -Original Message- From: Loren M.

Multicast Forwarding
Hi All I am a newbie to FreeBSD. We have the following setup in a lab environment: * PC1 (IP: 192.168.10.2/24) connected with cross over to wireless router A (IP: 192.168.10.1/24 - sis0) * PC2 (IP: 192.168.20.2/24) connected with cross over to wireless router B (IP: 192.168.20.1/24 - sis0) * Wireless router A (IP: 192.168.30.1/24 - wi0) connected with 802.11b to Wireless router B (IP: 192.168.30.2/24 - wi1) PC1 can ping PC2 and PC2 can ping PC1. Both Wireless router A and Wireless router B runs FreeBSD. The routing on this works but I cannot get UDP Multicast packets through. I have read in the FreeBSD docs that mrouted should be running and subsequently I have it running on both routers. Tcpdump shows the UDP multicast packets on Wireless router A from PC1 on sis0 and UDP multicast packets on Wireless router B from PC2 on sis0. Any help would be greatly appreciated.
