FRITZ!Box 6360 Cable (um) inbound TCP Test failed: NAT test failed:
#1
Hi,
i have some trouble with the TCP NAT test (not with the UDP NAT test) and i have a yelow smiley. I configured both TCP and UDP in my FRITZ!Box 6360 Cable (um)

Testing port TCP 50020 ...
NAT Error - Connection timed out (37.201.228.198:50020).

Testing port UDP 50020 ...
    Sending outbound packet and waiting for reply probe (timeout=5000)
    Sending completion event
OK !


FRITZ!Box 6360 Cable (um) / FRITZ!OS 06.04Internet, IPv6/  Internet, IPv4: DS-Lite-Tunnel

The ports opened by vuze:
$ netstat -an | grep 50020
tcp6       0      0 :::50020                :::*                    LISTEN     
udp6       0      0 :::50020                :::*                              

For comparision the ports opened by qbittorrent:
$ netstat -an | grep 50020
tcp        0      0 0.0.0.0:50020           0.0.0.0:*               LISTEN     
tcp6       0      0 :::50020                :::*                    LISTEN     
udp        0      0 0.0.0.0:50020           0.0.0.0:*                          
udp6       0      0 :::50020                :::*           


A telnet from my another computer in my home network to this port works (for vuze and for qbittorrent).
Why does vuze only open ip6 ports?

OS: ubuntu 14.04
Java 1.8.0_20
 Oracle Corporation
SWT v4403, gtk
Linux v3.13.0-36-generic, amd64
V5.4.0.0/4 az3

No Software firewll
No Antivirus Software
No Wireless Connection

Provider: Unity Media


Hopefully someone can give me a hint.

Best Regards,
Anselm

AFAIK tcp6 does NOT mean IPv6 - tcp6 can accept both IPv4 and IPv6 connections (just running netstat on my machine shows lots of IPv4 connections established over 'tcp6')

Not that this helps with your problem though :(

ok. Thank you. (Networking IPv6 User Guide
http://docs.oracle.com/javase/7/docs/tec...pv6_guide/)

I checked option>interface->Display->Nat Status

Now i see at the buttom a sign with a greed circle:  "NAT ok" (Reachability ok (TCP)) . Smeleys still green and TCP test fails.

The green smiley indicates that you have received incoming connections relatively recently - TCP OR UDP
