Default ftp-proxy

I need some help, I am a bit lost. I have a gateway on OpenBSD for a network of about 400 computers. I have about the same type of network as in the example of the official website.
[ COMP1 ] [ COMP3 ]
| |
---+------+-----+------- me_if [ OpenBSD ] net_if -------- ( Internet )
[ COMP2 ]

However, since the new installation of open bsd (4.6->4.8) I can’t connect to an ftp server from a computer :
That is a tcpdump of when I am trying to open a folder of an ftp server (webeleves.toto.fr) :
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 :

nat-anchor "ftp-proxy/*"
rdr-anchor "ftp-proxy/*"
rdr pass on $me_if proto tcp from $me_if:network to any port ftp -> port 8021

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

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
