Hello,
New to the forum and to firewalls in general..
We are currently in the testing phase of an astaro 220 security gateway v7 to use as a firewall/smtp server.
I'm having a few issues at the present moment with the firewall side of things, i'd appreciate some help..
Setup...
We have approx 20 public IPs assigned to various internal servers (1 NIC with public IP, the other NIC with private)..
The WAN router is directly connected to the internal network.
Im looking to place the firewall in between and packet filter these public IPs.
So far i've configured 2 interfaces on the astaro, one external, the other internal. I've then assigned the external interface with the additional public IPs.
I have created host definitions, one for each public facing server and configured DNAT to send the traffic from the additional Public IP to the corresponding server.
Packet filtering has also been setup, with the allow all rule for testing purposes.
I've tried pinging the additional external IPs without any joy, i can only get a reply from the one external IP assigned to the astaro.
Do i need to configure the SNAT aswell, or will it automatically route out, as the same IP is defined on the external interface.
Also do i add these additional addresses with subnet mask of 255.255.255.255 ?
Any help would be greatly appreciated.
Thanks
Atrixo
