Извиняюсь, если тема уже поднималась.
Честно юзала поиск, причем, не только по этому ресурсу.
Прошу помощи по настройке venet-сетки
Удалось найти кое-что только у альтоводов:

Если нужно что-то еще из информации по ПО, уточню.
Машина используется как HomeServer. Кое-что для дома (VPS-ки p2p-качалка с mldonkey, nfs-шара(через unfsd), и тд) и как очень дешевый вариант выделенного сервера под web и прочее (все-таки дата-центр дорогое удовольствие, а инет в Москве хороший)
Из домашней локалки(два десктопа, КПК, иногда ноутбук, один из интерфейсов ноды):
10.0.5.0/24
Соединение с любой VPS устанавливается успешно. Я юзаю несколько подсеток:
[shaggycat@hn scripts]$ ip r ls
10.0.10.20 dev venet0 scope link src 10.0.5.10
10.0.10.3 dev venet0 scope link src 10.0.5.10
10.0.9.26 dev venet0 scope link src 10.0.5.10
10.0.10.2 dev venet0 scope link src 10.0.5.10
10.0.9.21 dev venet0 scope link src 10.0.5.10
10.0.9.20 dev venet0 scope link src 10.0.5.10
10.0.10.10 dev venet0 scope link src 10.0.5.10
10.0.5.0/24 dev eth1 proto kernel scope link src 10.0.5.10
xx.xx.xx.xx/24 dev eth0 proto kernel scope link src xx.xx.xx.xx
169.254.0.0/16 dev venet0 scope link
default via xx.xx.xx.xx dev eth0
Здесь xx.xx.xx.xx статический внешний IP.
Так же, успешно проходят соединения через проброшенные(iptables PREROUTING) с внешного IP порты на различные VPS (то есть, работает web-server, "морда" mldonkey, и т.д.)
VPS друг друга успешно пингуют(обмениваются файлами по scp, и т д), даже если находятся в разных подсетях:
[root@test_centos_2 ~]# ifconfig venet0:0
venet0:0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00
inet addr:10.0.9.26 P-t-P:10.0.9.26 Bcast:10.0.9.26 Mask:255.255.255.255
UP BROADCAST POINTOPOINT RUNNING NOARP MTU:1500 Metric:1
[root@test_centos_2 ~]# ping -c 1 10.0.10.2
PING 10.0.10.2 (10.0.10.2) 56(84) bytes of data.
64 bytes from 10.0.10.2: icmp_seq=1 ttl=64 time=0.131 ms
--- 10.0.10.2 ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.131/0.131/0.131/0.000 ms
Но вот если они попытаются пинговать что-то в подсетке 10.0.5.0/24, например, компьютер, с которого я написала этот текст, получается какая-то бяка:
[root@test_centos_2 ~]# ping 10.0.5.2
connect: Invalid argument
[root@test_centos_2 ~]#
[root@test_centos_2 ~]# ping 10.0.5.10
connect: Invalid argument
То есть, не пингуется даже нода.
З.Ы. На VPS такой routing:
[root@test_centos_2 ~]# ip r ls
10.0.5.0/24 dev venet0 scope host
169.254.0.0/16 dev venet0 scope link
default via 10.0.5.10 dev venet0
[root@test_centos_2 ~]#
Подскажите, пожалуйста, куда, хотя бы, гуглить?
Буду благодарна любой помощи:)
