Hmm, I thought you were trying to get *out* to a dodgy ftp port.... I
didn't read your post properly. You don't need to use passive mode
for this.
Shouldn't your config say something like
redirect_port tcp 192.168.1.20:6002 216.32.46.218:6002
assuming the incoming packets are addressed to 216.32.46.218 ? Is
the 8002 below a typo ?
