OK, I will use eth0 because I'd like to accept connections from outside.
I have tried with its IP address and eth0.

Is nmap the way to check if the port is open te receive connections?

One thing has changed, syslog says:

Apr 20 19:01:12 hostname collectd[6502]: Initialization complete,
entering read-loop.
Apr 20 19:02:48 hostname snmpd[1132]: Connection from UDP:
[83.96.x.y]:45511->[83.96.x.y]

Does this mean it is able to receive?
