Crap, the subject line disappeared.

Performing cross-bridge DNAT requires IP forwarding to be enabled is
the error msg I get.

(BTW, the spam filter sucks).

Okay, that is the error I get. I googled around, but no one seems to
have my exact problem (and their solutions do not work for me.)

I have a stock Debian 4.0 setup, apt-get Xen 3.0, etc ... Now, I setup
a Dom1, and I run a webserver on Dom1 on port 80.

In Xen, my networking is (network-script network-nat) (vlf-script vlf-nat)

I setup iptables to -p tcp --dport 80 -d Dom0's_ip_address -j REDIRECT
--to  10.0.0.1

where  10.0.0.1 iss the ip address of Dom1 (from the view of Dom0;
i.e. on Dom0, if I do "wget  10.0.0.1", I get the webpage from Dom1)

Then, dmesg gives me the error mentioned above.

So I look around, and I see that according to /sbin;ifconfig the vif
correpsonding to my Dom1 is actually 10.0.0.128  ... so I try that,
but no tluck either.

Suggestions?
Thanks!
