<DIV> </DIV>
<DIV>Here with the same below setup iam trying to do the reverse operation i.e Lan PC will be working as a source and the reciver will be in the WAN.</DIV>
<DIV> </DIV>
<DIV>I could not able to receive the streaming in Wan VLC player .</DIV>
<DIV> </DIV>
<DIV>The logs are attached as .txt file along with this mail.</DIV>
<DIV> </DIV>
<DIV>I gave try by changeing the config.boot as below</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV> static-rps {<BR> rp *.*.2.38 {<BR> group-prefix 224.0.0.0/4 {<BR> }<BR> }<BR> }<BR></DIV>
<DIV> </DIV>
<DIV>Here *.200.2.38 is my eth0 public ip. eth1 is 192.168.1.1 and my lan pc is 192.168.1.10</DIV>
<DIV> </DIV>
<DIV>Should i configure or make some changes in my Wan router like for this specific group 239.1.2.3 rp is 1*.200.2.38 . But my doubt is the xorp router is receving the igmp packets from private nic card i.e in eth1 .</DIV>
<DIV>So from eth1 how will it pass the info to eth0. ( is the interface definitions in config.boot will take care ? ).</DIV>
<DIV> </DIV>
<DIV>I have followed the below config.boot only ( which is already in this thread ) except adding the static-rps and register_vif in the pimsm4 and mfea4</DIV>
<DIV> </DIV>
<DIV>Thanks for all your support till now.</DIV>
<DIV> </DIV>
<DIV>regards</DIV>
<DIV>kanth </DIV>
