I still cannot ping to the public network(184.20.199.21)?This is a valid IP
when I ping from within the public network:
I have suffered from the same problem with my NAT cluster.
I run version 0.9.15 on my director with a NAT cluster with three
real-servers. The cluster balances telnet and ssh connections and is used
for running compute jobs. People also use the cluster as a central server
for running remote netscape sessions on windows machines, and telnetting to
other boxes. Standard TCP connections out to the outside work seem to work
fine, you can run netscape remotely or lynx and get a connection fine.
However I cannot ping machines from within the cluster. I decided just to
live with it but seeing as someone else is asking I thought I would add my
experiences.... My cluster works fine except for this problem.
ipchains is configured as below:
Chain input (policy ACCEPT):
Chain forward (policy DENY):
target prot opt source destination ports
MASQ all ------ ugnode1 anywhere n/a
MASQ all ------ ugnode2 anywhere n/a
MASQ all ------ ugnode3 anywhere n/a
MASQ icmp ------ ugnode1 anywhere any -> any
MASQ icmp ------ ugnode2 anywhere any -> any
MASQ icmp ------ ugnode3 anywhere any -> any
Chain output (policy ACCEPT):
and ipvs is configured as:
