I'm needing some help related to one videoconference that i was setting up.
When i make the call for the videoconf the remote user says that he answer the call but for me keeps only ring , and when he make the call we can see everything but the remote user don't see me no sound nor video.
The only different thing that i got in the logs
Was one Deny TCP (no connection) from xxx to xxx flags SYN ACK on interface xxx (i don't have the log for this one i know this is the error)
4 Sep 15 2010 11:18:57 313005 No matching connection for ICMP error message: icmp src INTERNET:201.31.X.X dst -DMZ01:189.43.X.X (type 3, code 3) on INTERNET interface. Original IP payload: udp src 189.43.X.X/49152 dst 192.168.X.X/55844.
I have a static nat 10.21.1.250 to 189.43.X.X
Do you guys have any ideia what might be causing it?
Thought about it but they are able to conect here and i can hear and
seeing video... ...
I found ond einformation on the net someone meybe can confirm if is really it
"(no connection) errors are generally caused when an IP device attempts to respond to a previously opened TCP/IP connection after the connection has 'timed out' in the firewall's stateful connection table.
This can happen for numerous reasons. The most common is that the connection timeout on the firewall is set to low. This can happen more specifically across slower LAN or WAN links or if a server is slow to respond to requests.
For example a client sends a SYN request to a server. The server takes to long to respond and the timeout set on the firewall closes the stateful connection because it has not detected at SYN-ACK response from the server within the timeout period set on the firewall. Therefore when the server finally sends the SYN-ACK packet, the firewall has already 'timed-out' the connection and so cannot match the packet sequence in its stateful connection table. As there is no match in the stateful table, the firewall reports the return packet as (no connection) and drops the traffic."
