Hi.
I would like to be able to access our internal servers by the external ip from within the network. Is this possible with an Astaro firewall?
As an example. GlobalOptions resolves to a public IP 208.66.47.50. That is protected by the astaro box. A user, also protected by the astaro, cannot connect to that public IP.
Cisco calls this "Nat on a stick"
Network Address Translation on a Stick [IP Addressing Services] - Cisco Systems
Normally I would make this netfilter rule, but I'm not sure how to do it via the web interface.
-A POSTROUTING -s 192.168.0.0/255.255.255.0 -d 192.168.0.0/255.255.255.0 -j SNAT --to-source 192.168.0.1
Thanks in advance,
