Proxy exceptions and move to external hosting

[smarties11]

Hi,

 

We use our external domain as our internal one too, and up to now have hosted our website internally. I'm now moving this to external hosting in order to air gap it from our network.

 

So, up to now we have http://www.ourschool.co.uk pointing to our webserver internal IP on our internal DNS, and have *.ourschool.co.uk set as proxy exceptions so that this isn't proxied through our SmoothWall. On our external DNS, we have http://www.ourschool.co.uk pointing at an external IP which is NAT'd to our webserver.

 

I've set up our external hosting and transferred our site to a test subdomain and it works great externally. Internally, I've set up a DNS record for the subdomain on our internal DNS pointing at the IP of our external hosting server. But of course this only works if I remove *.ourschool.co.uk from the proxy exceptions.

 

What's the best thing to do in this scenario? We have a number of internal services so I don't want to list them individually as exceptions if I can help it.

 

If I leave the wildcard exception in place, is there a way to tell SmoothWall that this is not internal and therefore to proxy the request externally?

Can you not just add the external IP of your new webhost to proxy bypass and as a destination IP exception in the firewall, should go direct out then.

Yep, good thinking - done, tested & working :-)

 

Thank you!
