[LON-CAPA-admin] Can't access published resources

Thu Dec 12 11:09:35 EST 2013

Ok,  I set up a separate packet filter (port 80) on the firewall for this
server only and configured it to set the source IP to 66.51.156.71.

I am still getting these log messages.  Can you check your logs again to
make sure my firewall is forwarding on the correct IP address now?

Thanks

Ken
