192.168.0.238 no IP 192.168.0.96
I transmitted one file with 56940 Bytes from PC1 to PC2 via ftp
in 13.24 sec. (4.30 KByte/s):
Here is the output from "ipfw show":
00010 69 75877 pipe 1 ip from 192.168.0.238 to 192.168.0.96
00150 0 0 allow ip from any to any via lo0
00200 0 0 deny ip from any to 127.0.0.0/8
65535 12 0 allow ip from any to any
Here is the output from "ipfw pipe show":
00001: 1.000 Mbit/s 0 ms 100 sl. -- 10 pkts (352720 B) 0 drops
Thanx,
