[Gllug] Unexpected ADSL firewall data

[Chris Bell]

Hello,
   I have just seen a log from my IPCop firewall covering the interface that
connects to my ADSL modem that shows TX packets just under half of the RX
packets, but TX bytes nearly five times the RX bytes.

eth2      Link encap:Ethernet  HWaddr xx:xx:xx:xx:xx:xx
          inet addr:192.168.1.2  Bcast:192.168.1.255  Mask:255.255.255.0
          UP BROADCAST RUNNING  MTU:1500  Metric:1
          RX packets:96315557 errors:0 dropped:0 overruns:0 frame:0
          TX packets:54646909 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:881505797 (840.6 MB)  TX bytes:4218403628 (4022.9 MB)

   The local network interface looks much more reasonable, (it connects to a
busy multi-way hub, not a switch).

eth0      Link encap:Ethernet  HWaddr xx:xx:xx:xx:xx:xx
          inet addr:192.168.2.1  Bcast:172.21.3.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:55461808 errors:2 dropped:142 overruns:0 frame:1
          TX packets:95885334 errors:730610 dropped:0 overruns:0 carrier:730610
          collisions:4363820 txqueuelen:1000
          RX bytes:4289333295 (4090.6 MB)  TX bytes:115225054 (109.8 MB)

   I am puzzled.



lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:41139 errors:0 dropped:0 overruns:0 frame:0
          TX packets:41139 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:4005601 (3.8 MB)  TX bytes:4005601 (3.8 MB)
