    I've got IP-camera attached to router. I found there are some odd ports open and because of that I wan't to monitor where traffic goes from camera. How to do this?

    Is it possibly to monitor routers traffic from another computer with Wireshark or do I need to do monitor it from router?

    Router is Asus RT-N10U and Tomato Firmware 1.28.0000 MIPSR2-140 firmware.

    And how to block unwanted traffic from single IP-address?

    What exactly are you looking to gain via "monitoring"? Are you just looking to log IP addresses for any outside connection made to your IP camera? Or is there a need to log every single packet seen on the wire to/from your IP camera?

    Assuming the single IP address you're wanting to block is not a local one, placing this line ( replacing the X's with the IP ) in the Firewall section under Administration->Scripts of the routers GUI will drop any traffic that has said IP address as the source:

    iptables -t filter -I FORWARD 1 -s X.X.X.X/32 -j DROP

    Any IP-address is enough. There's Danale cloud service available, so camera sends pics there when it's enabled.

    But any unwanted connection should be found and blocked. Thank for the iptables tip, hopefully I wont need it..

    Could I install tcpdump or something with SSH? Does tomato support opkg -packages? Is there repository available?

    Yes, optware/entware-ng. You can use tcpdump via ssh etc.. or run rpcapd and use wireshark on a remote machine that will capture through rpcapd.
