Question

Publishing a WEbserver through a Firebox X1250e

Asked by: DorisOnline

We currently have three webservers setup, two of which can only be accessed over https.

We have just recently purchased a Watchguard Firebox x1250e, and I am trying to publish one of our https servers through the 1250, but am not having much luck.

I can access the Internet through the firebox.

I have the firebox connected to the router through the external port.
I have teh firebox connected into the dmz via the trusted port.
I have setup the next port as an optional port and assigned the external IP for our webserver to that port. I then have that port connected into the DMZ.
The webserver can see the firewall (ping) so thats fine, and the webserver is using the firebox as its default gateway (it can access the internet through the firebox)
I have setup a policy to allow HTTPS-Proxy (and this is where I am getting stuck I think):
Do I configure it to allow, for example,:
Any External to Any Optional?
External to Optional?
Optional to Host IP address?
External to Host IP address?

I think I have tried all of these but have not had any joy. I have read through most of the documentation but cannot find the answer. Any help would be great appreciated.

Doris.

you have to configure NAT
Any connectuon (port 80,443) on the external interface needs to be proxied to the web server's IP in the DMZ which means that the firewall needs to rewrite the destination IP (from your external public IP to your internal DMZ IP). If it is a statefull inspection firewall, that's all. Otherwise you need to make another NAT rule the other way around.

Thanks AHoffmann, I have setup 1-1 NAT which has resolved the issue.

Appreciate the help.
