First of all, I'm not sure what all that netbios traffic below is about. If you are using user ppp, then you should do "tcpdump -n -i tun0". That will show the traffic actually going outside your local area network. It looks like you are dumping out your ethernet interface. Also, are you using "ppp -alias" or do you have a registered subnet? > > 15:09:21.309164 stentor.ferraro.net.netbios-ns > > 192.168.1.255.netbios-ns: udp 68 > 15:09:21.312862 0:40:5:4c:41:21 > 3:0:0:0:0:1 sap f0 ui/C len=44 > 2c00 ffef 0100 0000 0000 0a00 0000 0000 > 0000 0000 0000 0000 0000 0000 4a4f 4520 > 2020 2020 2020 2020 2020 2003 > 15:09:22.088303 stentor.ferraro.net.netbios-ns > > 192.168.1.255.netbios-ns: udp 68 > 15:09:22.209690 0:40:5:4c:41:21 > 3:0:0:0:0:1 sap f0 ui/C len=44 > 2c00 ffef 0100 0000 0000 0a00 0000 0000 > 0000 0000 0000 0000 0000 0000 4a4f 4520 > 2020 2020 2020 2020 2020 2003 > 15:09:22.883083 stentor.ferraro.net.netbios-ns > > 192.168.1.255.netbios-ns: udp 68 > 15:09:23.257784 0:40:5:4c:41:21 > 3:0:0:0:0:1 sap f0 ui/C len=44 > 2c00 ffef 0100 0000 0000 0a00 0000 0000 > 0000 0000 0000 0000 0000 0000 4a4f 4520 > 2020 2020 2020 2020 2020 2003 > 15:09:23.669735 stentor.ferraro.net.netbios-ns > > 192.168.1.255.netbios-ns: udp 68 > 15:10:21.354658 stentor.ferraro.net.netbios-ns > > 192.168.1.255.netbios-ns: udp 50 > 15:10:22.108746 stentor.ferraro.net.netbios-ns > > 192.168.1.255.netbios-ns: udp 50 > 15:10:22.864608 stentor.ferraro.net.netbios-ns > > 192.168.1.255.netbios-ns: udp 50 > 15:10:35.248136 stentor.ferraro.net > he.net: icmp: echo request > 15:10:36.441001 stentor.ferraro.net > he.net: icmp: echo request > 15:10:37.954249 stentor.ferraro.net > he.net: icmp: echo request > 15:10:38.972695 stentor.ferraro.net > he.net: icmp: echo request > 15:11:20.590660 0:40:5:4c:41:21 > 3:0:0:0:0:1 sap f0 ui/C len=170 > 2c00 ffef 0800 0000 0000 0000 4e45 5420 > 2020 2020 2020 2020 2020 201e 5354 454e > 544f 5220 2020 2020 2020 2000 ff53 4d42 > 2500 00 > 15:11:20.648005 stentor.ferraro.net.netbios-dgm > > 192.168.1.255.netbios-dgm: udp 208 >
