We are facing a problem when using UDPCast in multicast mode. When I start a transfer from
one pc to another, no problem.
But when I start a transfer from one pc to two or more pc's, new booted clients
can't get a ip-address from the DHCP-server anymore.
We have a rather complicated network, with lots of subnets.
I contacted network-support and they presume it could be a conflict with the VVPR (Virtual
Router Redundancy Protocol) which also uses multicast.
I already played with several settings, like:
udp-sender --ttl 1 and udp-receiver --ttl 1
udp-sender --ttl 2 and udp-receiver --ttl 2
udp-sender --mcast-rdv-address 18.104.22.168 and udp-receiver --mcast-rdv-address 22.214.171.124
But the problem persists.
The problem only starts when the actual transfer is initiated. While udp-receiver is
waiting for the clients to connect
there is no problem yet, but as soon as data is being transferred (multicast), new booted
clients in the network can't find
the DHCP-Server, don't get an IP-addresses, can't PXE boot anymore.
I hope somebody understands what is going on here, and if there is a solution.
We really need udpcast in our environment.
Thanks in advance for all help.
