Message-ID: <46EA5574.4000401@aaanet.ru> (raw)
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
inet 127.0.0.1/8 brd 127.255.255.255 scope host lo
3: venet0: <BROADCAST,POINTOPOINT,NOARP,UP,10000> mtu 1500 qdisc noqueue
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
to cooked socket
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on venet0, link-type LINUX_SLL (Linux cooked), capture size 96
bytes

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