Hi!

Im having a little problem with the routing in my cluster.

Setup:
Public IP: let us call it.. x.x.x.x

Public IP -> SlaveCluster eth0 x.x.x.x
eth1 172.16.2.4
eth2 172.16.2.2

MasterCluster eth0 172.16.2.5
Virtuall machines vmbr0 10.72.2.1
vm guest 10.72.2.3

The thingy here is.. that eth1 inside Slave cluster cant talk to the internet.

Inside the vm guests {10.72.2.0/24} i can ping eth0 172.16.2.5 but not Slavecluster eth1 172.16.2.4

From eth1 Slavecluster to internet

# ping -I eth1 8.8.8.8
PING 8.8.8.8 (8.8.8.8) from 172.16.2.4 eth1: 56(84) bytes of data.
From 172.16.2.4 icmp_seq=2 Destination Host Unreachable

From vm guest to Slavecluster eth0

# ping 172.16.2.5
PING 172.16.2.5 (172.16.2.5) 56(84) bytes of data.
64 bytes from 172.16.2.5: icmp_seq=1 ttl=64 time=0.127 ms

I can ping from Slavecluster eth1 172.16.2.4 into vm guest in 10.72.2.0/24

# ping 10.72.2.3
PING 10.72.2.3 (10.72.2.3) 56(84) bytes of data.
64 bytes from 10.72.2.3: icmp_req=1 ttl=63 time=0.294 ms

But not from Slavecluster eth0 x.x.x.x

# ping -I eth0 10.72.2.3
PING 10.72.2.3 (10.72.2.3) from x.x.x.x eth0: 56(84) bytes of data.

What Im a doing wrong? Can someone help. I've been searching for hours now.

Ive tryed from Slavecluster:

# ip route add default via x.x.x.0 dev eth1
RTNETLINK answers: No such process

I'm not sure you understand how support forums work, but the entire point is to present a problem and then post the solution for all to see and benefit from. Even if you solve your own problem. Here's to hoping you are still around and feel like sharing!
