Not sure how to generate the IGMP packet, it's been a while since I worked with multicast. > 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.=20 >=20 > Any help would be greatly appreciated. >=20 > Albert >=20 > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.o= rg" --=20 I sense much NT in you.
