Hi, I'm only interested in applying the IPS to HTTP traffic, which is already entering and exiting the UTM as I am using the WAF.
From my understanding of how the IPS works, I see no reason it couldn't be applied to the WAF traffic as well, even with a single NIC. However, it would apparently require Sophos to change something, as it isn't working presently.
I realize that putting in a second NIC could 'fix' this, but I'm not sure that would be a good fit with our network layout.
The license count seems rather strange in the single-NIC config... instead of counting the servers protected by the WAF, random DMZ IPs are being counted.
These IPs are not communicating through the proxy.
This is troubling as it means that a 10-IP license may not be enough, even though we're only protecting a few IPs.
The UTM proxy's interfaces are on .20 and .29, /24.
The protected servers are in a different subnet, via the ASA.
