I have just enabled the eth2 (DMZ) on my ASL to host a web server. After doing this I have noticed that there is a route between internal interface (eth0) and the DMZ.
I can ping the 10.0.0.x address of my webserver from my internal network of 172.16.0.x and visa versa.
The only packet filter rule I added was Any - HTTP - Webserver - Allow to open port 80 to the world.
There is a NAT rule DNAT_WebServer Any -> eth1_Interface__/HTTP None Webserver
Webserver is defined in Networks as 10.0.0.x – 255.255.255.255
Nothing else points to eth2!
I have checked the USR_FORWARD chain and all seems okay there.
I cannot see where the route is coming from or how it is happening.
Any ideas?
BTW: ASL 4.021
