Your post of was very helpful.
Do you know a way to input the multicast route using system-config-firewall ? I can do it manually, its just that would be the only manual firewall setting I'd have and then I'd forget I had it.
Isn't there a way to tell a firewall to allow dynamic port allocation ? I believe my Cisco E4200 wireless router has this option. Is there a section of ports that is allowed for just this sort of thing ?
I'll take another stab at getting it going later tonight.
Thanks for the reply.
