Xen users - May 2008 - Networking Problems ( Xen 3.2 )

Hi,

I have just upgraded from Xen 3.0 to Xen 3.2, and the same problem 
occurrs on both versions. My networking seems to be intermittant. I can 
ping a host, but not telnet to it. When I try a traceroute I get this:


root@sql2:/var/lib# traceroute 192.168.100.1
traceroute to 192.168.100.1 (192.168.100.1), 30 hops max, 52 byte packets
 1  192.168.100.112 (192.168.100.112)  0.063 ms !C  0.084 ms !C  0.043 ms !C


According to `man traceroute`, !C means:

/    !A, !C (access to the network or host, respectively,  is  prohibited)


/I''m using Centos 5.0 Dom0 and Debian Etch in the DomU, but I have the 
same setup on a different (identically setup, but still on Xen 3.0) 
server with no problems.

Any ideas?

It turned out that my problem was iptables running on the dom0, when I 
switched it off, it works, switch it on it breaks again.

I made the firewall more permissive on our internal network and it works 
fine now.
