Re: [Xen-users] Strange Networking Issue
To answer your question about eth0 vs. eth1, on the dom0 eth1 has the
public IP but the below dump from ip addr list was on the domU showing
that the .242 IP was added to the domU in the same way as the .240 IP
however .240 reaches the domU and .242 does not.
Yes, pingable means from the outside world. Otherwise I will specify
for clarity.
No firewalls.
Other services are also unreachable.
tcpdump was a great tip, thanks. I'll add that to my tool belt. The
dom0 is receiving the ping request for .242 but that IP is added to the
domU. The domU is receiving the ping request for .240 however.
You made the following statement which I don't understand: "Another
thing is that your gateway/Dom0 ip is looking exactly like a transfer
network,
75.126.153.176/29 for routing purpose. You should get some
information from your provider how exactly the routing setup is."
What exactly are the implications of them setting up the dom0 IP in
that way and why does it matter?
I do appreciate all of your help. Thanks much!

You can see that all IP's are added in the same way yet only .240 is
pingable. I can add the IP manually to dom0 and get it to ping so I'm
thinking there is some bug in this latest version of xen. Does anybody
else have any other conclusion?
pingable means from outside, right. So are there any firewalls between
outside and xen?
have you tested any other service, like http? try that.
does your xen box get/answer the ping? tcpdump -i eth0 icmp. Do you see
any echo/echo-replys generated from your box?
According to your first mail, eth1 is the if with the public
interface! Why are the addresses configured on eth0?
Another thing is that your gateway/Dom0 ip is looking exactly like a
transfer network,
75.126.153.176/29 for routing purpose. You should get some
information from your provider how exactly the routing setup is.
I dont believe it is xen, i have a similar setup.
