In a scenario where I have a lets say /29 routable network and I use one of the addresses for my Internet interface. Behind this address I hide most of my Internal networks, which works just fine. Then I want to hide my guest network behind one of the remaining addresses. Or maybe a SIP server because my ISP want's my SIP traffic on it's own IP address. I want to use hide method so that I can hide more objects behind that address in the future
So, I either make a manual entry like:
|Src addr||Dst addr||Service||Xlate Src||Xlate Dst|
Or I can select hide behind one of my external addresses on the network/host object.
I make sure these NAT rules come before any automatic or other rules that would affect the result and my gateway is not hiding these addresses. I have also made sure the ARP boxes are ticked under global properties NAT section. My Internet interface IP address is defined with the /29 mask. If i type 'route' in the cli the network is in the table.
If I hide these hosts behind the gateway address it all works.
Where do I look?
I am asking because I recently found this problem at two of my clients and I haven't figured it out yet. The affected environments are R80.20M1 Mgmt + R80.10 GW and full R80.20.
