OSR5 FAQ

I am using the OSR5 ipnat, but ftp only works in passive mode.

Ian Peattie provided this:

Supposing your ipnat configuration looks like this:

 #!/bin/ksh
 MYIP=`ifconfig net0 | grep inet | awk '{ print $2 }'`
 ipnat -F
 ipnat -C
 ipnat -f - <<EOF
 map net0 192.168.200.0/24 -> $MYIP/32
 EOF
 

To add the ftp proxy, change your script to this:

  ----(start)---
  #!/bin/ksh
  MYIP=`ifconfig net0 | grep inet | awk '{ print $2 }'`
  ipnat -F
  ipnat -C
  ipnat -f - <<EOF
  map net0 192.168.200.0/24 -> $MYIP/32 proxy port ftp ftp/tcp
  map net0 192.168.200.0/24 -> $MYIP/32
  EOF
  ----(end)----
 

and then re-run it.
