[Openswan Users] Openswan<->Freeswan FTP Packet lost

i have set up an roadwarrior from openswan (fedora core 3, Kernel 
2.6.9-1.667) to an older static freeswan (the freeswan side has
25 very well working roadwarrior-clients with net-to-net connections)

I can ping from net to net, i can telnet, smtp works, but
ftp lost packets.

The mystery is, from all Linux-Clients at the Freeswan-Side i can FTP
to an SCO-Openserver on the Openswan side, but not from an SCO-Openserver
on the  Freeswan-Side to the SCO-Openserver on the Openswan-Side.

>From the SCO-Openserver on the Openswan-Side, I can FTP-Login to the
SCO on the Freeswan side, and then the transfer stop.

Here is my ip-up Script on the Openswan-roadwarrior:

192.168.30 is the Openswan-Net
192.168.18 is the Freeswan-Net is the Openswan-Roadwarrior internal network address
/sbin/iptables -P FORWARD ACCEPT
/sbin/iptables -A FORWARD -i ppp0 -m state --state NEW,INVALID -j REJECT

 		--state NEW,ESTABLISHED -m mark  --mark 50 -j ACCEPT

/sbin/iptables -I INPUT -i ppp0 -d -m state \

TX for any help!
