Hi,

We have some problems with vservers.

Our machine manage 2 network interfaces, 1 private interface ( 10.3.0.0
) and 1 public interface ( 217.X.X.X ).

The routing table we have is:

vserver01:~# ip route
217.X.X.X/27 dev eth0 scope link
10.3.0.0/24 dev eth1 scope link
10.0.0.0/12 via 10.3.0.1 dev eth1
127.0.0.0/8 dev lo scope link
default via 217.116.2.129 dev eth0

vserver01:~# route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
217.XXX.XXX.X * 255.255.255.224 U 0 0 0 eth0
10.3.0.0 * 255.255.255.0 U 0 0 0 eth1
10.0.0.0 10.0.0.1 255.240.0.0 UG 0 0 0 eth1
127.0.0.0 * 255.0.0.0 U 0 0 0 lo
default 217.XXX.XXX.X 0.0.0.0 UG 0 0 0 eth0

Working in local mode (monitor and keyboard directly conected to the
machine), we dont have any problem to ping a vserver from root system:

vserver01:~# ping 217.XXX.XXX.135
PING 217.XXX.XXX.135 (217.XXX.XXX.135) from 217.XXX.XXX.135 : 56(84) bytes of data.
64 bytes from 217.XXX.XXX.135: icmp_seq=0 ttl=255 time=45 usec
64 bytes from 217.XXX.XXX.135: icmp_seq=1 ttl=255 time=30 usec
64 bytes from 217.XXX.XXX.135: icmp_seq=2 ttl=255 time=31 usec

--- 217.XXX.XXX.135 ping statistics ---
3 packets transmitted, 3 packets received, 0% packet loss
round-trip min/avg/max/mdev = 0.030/0.035/0.045/0.008 ms

But, when we work conected through ssh or telnet (conected to 10.3.0.2),
we have some problems:

vserver01:~# ping 217.XXX.XXX.135
PING 217.XXX.XXX.135 (217.XXX.XXX.135) from 10.3.0.2 : 56(84) bytes of data.

64 bytes from 217.XXX.XXX.135: icmp_seq=2 ttl=255 time=31 usec
