Всем привет!
есть ALM 4 стоит Openvz в котором есть
VE
[root@mailserver /]# ip a
1: lo: <LOOPBACK,UP,10000> mtu 16436 qdisc noqueue
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

    link/void
    inet 127.0.0.1/24 scope host venet0
    inet 192.168.99.1/32 scope global venet0:0

в iptables усть
$EXTERNAL_DDRESS равен IP этого ppp999   
$IPTABLES -t nat -A PREROUTING -p TCP -d $EXTERNAL_DDRESS --dport 25 -j 
DNAT --to-destination 192.168.99.1:25

Если я захожу в ve и делаю  tcpdump. Захожу естественно на 25 со 
стороннего внешне IP
[root@mailserver /]# tcpdump -i venet0 port 25
tcpdump: WARNING: arptype 65535 not supported by libpcap - falling back

Почему пакеты идут через 192.168.100.10 ? Что не так сделал и что можно 
покрутить?
