[Udpcast] multicasting over satellite

[Sinan Nalkaya]

hello, i have a server and client, there are about 50 routers between
them and connection type is satellite, i am allowed to use addresses
between 224.1.1.1 - 239.1.1.1 and ports between 1000 - 6000 on server,
and have a multicasting policy, my all switches configured properly
about IGMP Snooping

my problem is i cannot get multicast from clients. here is my log
Client Side :
$ udp-receiver -f deneme.mpg --portbase 3000 --interface eth1
--mcast-all-addr 224.2.2.1 --nokbd
Udp-receiver 2004-05-31
UDP receiver for deneme.mpg at 192.169.132.2 on eth1
received message, cap=00000019

The Server Side:
# udp-sender -f poas.mpg --interface eth1 --ttl 200 --portbase 3000
--mcast-all-addr 224.2.2.1 --nopointopoint

without --nopointopoint parameter it works very fine if using just 1
client, but when i try on multiple client, i can never get the
multicast from client. what should i do? any help would be
appreciated.
Thank you
