    No TV with Internet. gigantic syslog

    running 64 bit Ubuntu natty on an AMD 6 core processor.

    I am currently getting, at the rate of 5 per second, lines identical to this (except for time), in my /var/log/syslog

    Sep 20 09:54:16 ma78-u17 kernel: [80684.300613] Inbound IN=eth0 OUT= MAC=00:1f:d0:9c:f9:09:00:18:dd:01:b9:fe:08:00 SRC= DST= LEN=1356 TOS=0x00 PREC=0x00 TTL=2 ID=19989 DF PROTO=UDP SPT=5004 DPT=52384 LEN=1336

    SRC= means this is from my network TV tuner, an hdhomerun. I presume the hdhomerun is sending something.

    While I'm connected to the Internet, as I am now, I can't access the hdhomerun. Nothing. It is not detected. But pinging gets a response time. As soon as I disconnect (I have dialup Internet), the hdhomerun is back. I would like to fix this. I figure the errors and the missing hdhomerun are connected.

    What is putting these error(?) messages in the syslog? How can I figure that out?

    What is blocking the hdhomerun when I dial-up? avahi? NetworkManager? dnsmasq? How can I track it down? What can I change?

    There is no firewall running according to System Monitor, at least not ufw or firestarter. Will iptables do something which blocks ip's even with no firewall running?

    There are dhcp leases being written, according to the syslog, to the hdhomerun, but some or all may be be old.

    There is no router Just my other computers (which have been off for several days) and the hdhomerun are connected to the network interface through a switch.

    server-duid "\000\001\000\001\025\362i\334\000\037\320\234\371 \011";

    ---end of lease file

    For some unknown reason, the last lease starts in the future. The current time is 13:09 by the tray clock, which is before 16:31.

    Believe me, I have tried many FAQs and HOWTO's over the last few weeks, but this guessing approach has gotten nowhere.
