Unfortunately no one can be told what fun_plug is - you have to see it for yourself.

Today a disabled the internet connection on my router. Later on I noticed today lsof on the DNS-323 took a long time to execute. After reestablishing the internet connection lsof is completed within seconds.
I looked into it and found that op_server has opened a connection to ALL-SYSTEMS.MCAST.NET Port 13579. Why is that? I'm not downloading anything (never used that feature)
Output lsof | grep op_server
op_server 1602 root cwd DIR 1,0 1024 2 / op_server 1602 root rtd DIR 1,0 1024 2 / op_server 1602 root txt REG 7,0 53392 4551396 /sys/crfs/sbin/op_server op_server 1602 root mem REG 1,0 19492 1422 /lib/ld-uClibc-0.9.28.so op_server 1602 root mem REG 1,0 28724 1419 /lib/libconfuse.0.0.0 op_server 1602 root mem REG 1,0 10196 1423 /lib/libcrypt-0.9.28.so op_server 1602 root mem REG 1,0 312136 1424 /lib/libuClibc-0.9.28.so op_server 1602 root mem REG 1,0 37580 1432 /lib/libgcc_s.so.1 op_server 1602 root 0r CHR 1,3 79 /dev/null op_server 1602 root 1u CHR 4,64 164 /dev/ttyS0 op_server 1602 root 2u CHR 4,64 164 /dev/ttyS0 op_server 1602 root 3u sock 0,4 1454 can't identify protocol op_server 1602 root 4u IPv4 1455 UDP ALL-SYSTEMS.MCAST.NET:13579
What's going on here?

Ok, google is my friend.
So I do not have to worry, because it is local multicast? But where does it come from? And why is lsof blocked when there is no internet connection - which is definitly not my local net?
Maybe I didn't get it - sorry for that.

It's used for upnp and bonjour.

Because the name resolution does not work then.
