Hi all,

I have read and implemented the configuration for Xen dom0 as described
in "Xen - Shorewall in Bridged Xen Dom0". I have one question though.

It seems to me that there is no protection for Dom0 in the configuration
as described.Shouldn't the lines in /etc/shorewall/policy :

ursa            all             ACCEPT
net             ursa            ACCEPT

rather be

ursa            all             ACCEPT
net             ursa            REJECT INFO

And then allow ports in in /etc/shorewall/rules -- The only port I can
see useful for Dom0 is port 22 for remote maintenance?
E.G.

ACCEPT          net                xen    ssh #where xen is enbr0:vif0.0


At least in my setup for servers I have a minimal Dom0 and just use it
to run and control the virtual machines. It needs the most protection as
breaching Dom0 will result in all virtual machines being vulnerable.

Am I missing something?

Regards

Mark
