Hi

RTMFP can work with most cone NAT configurations and many firewall configurations.

Symmetric NAT in combination with certain firewall or NAT cases at the other end blocks the ability to establish a peer-to-peer connection.

If one end is a symmetric NAT with a single IP address, Flash Player cannot connect to peers behind other symmetric NATs or behind port-restricted cone NATs (or port-restricted firewalls).

If one end of a connection is a symmetric NAT with multiple IP addresses, connection to peers behind other symmetric NATs or behind address-restricted (and probably port-restricted) cone NATs (or address-restricted or port-restricted firewalls) is impossible.

No matter what Flash Player tries to do to “punch a hole” through the restricted cone NAT or restricted firewall to let the other peer through, the other end moves to a new address and/or port number that doesn't match.

The hole that was created is no longer applicable.

Thanks

Conor

Hi I would guess UDP is not allowed on one or both networks in the first instance but not in the second.

I found that's problem. I use Symmetric NAT.

I heard Skype is using like super node.

Supernode (networking) - Wikipedia, the free encyclopedia

is anyone know super node for flash?
