Hello. I''m new to this list. I''m trying to set up multicast routing between two networks: Internet ^ | Windows box | | UserModeLinux A <-----> Colinux Router <-----> UserModeLinux B running mrouter I''m using a 2.6.8 kernel on Colinux with Multicast/Multicast routing support activated. The UMLs are supporting Multicast. I''m trying to make A and B communicate over a Multicast address with the emcast utility. Mrouter on Colinux is receiving the membership report from A end B. Mrouter is also filling the tables: colinux:~# cat /proc/net/ip_mr_cache Group Origin Iif Pkts Bytes Wrong Oifs 080706E1 0114A8C0 2 3 117 0 1:1 080706E1 010AA8C0 1 4 123 0 2:1 ^ | Output Interfaces But nothing is forwarded: colinux:~# cat /proc/net/ip_mr_vif Interface BytesIn PktsIn BytesOut PktsOut Flags Local Remote 1 tap0 123 4 0 0 00000 FE0AA8C0 00000000 2 tap1 117 3 0 0 00000 FE14A8C0 00000000 ^ | Nothing Out I surely missed something but don''t know what. I would be pleased if anybody could help...

Emcast has the "good" idea to set the default ttl to 1. So be careful !!! Emcast -t 2 and it passes the router... I hope nobody else will lose so much time !
