Gateway Openbsd,

Hello,

I need some help, I am a bit lost. I have a gateway on OpenBSD for a network
of about 400 computers. I have the same type of network as in the example.

  [ COMP1 ]    [ COMP3 ]

      |            |                               

   ---+------+-----+------- me_if [ OpenBSD ] net_if -------- ( Internet )

             |

         [ COMP2 ]

 

However, since the new installation of open bsd I can't connect to an ftp
server from a computer :

That is a tcpdump when I try to open a folder of an ftp server
(webeleves.toto.fr.ftp) :

03:21:22.339949 comp1.me.toto.fr.57526 > webeleves.toto.fr.ftp: S
2170901005:2170901005(0) win 8192 <mss 1460,nop,wscale 2,nop,nop,sackOK>
(DF)

03:21:22.801066 comp1.me.toto.fr.57526 > webeleves.toto.fr.ftp: . ack
2164733286 win 16378 (DF)

 

Those lines were on my pf.conf on the 4.6 version which worked :

 

#ftp-proxy 

nat-anchor "ftp-proxy/*"

rdr-anchor "ftp-proxy/*"

rdr pass on $me_if proto tcp from $me_if:network to any  port ftp ->
127.0.0.1 port 8021

 

 

When I install the 4.8 version, I changed those lines and  I put instead :

 

#ftp-proxy

anchor "ftp-proxy/*"

pass in log quick on $me_if proto tcp to !$me_if port ftp rdr-to lo0 port
8021

..then all the rules match.

 

And since this new installation, I can't open a folder in a ftp server.

Can you help me ?

Thank you
