Equallogic Group Manager - SAN HQ

In the EQL Group Manager GUI(214.121.x.y) , under "Group Configuration - General - SAN Headquarters", it lists san-hq, their status, ip address, etc. Where is it getting this info from? It is showing internal ips', not external NAT'd ones. Can it be changed? I would have expected to see the internal IP (193.168.x.y) of the NAT IP (214.213.x.y) being shown. The SANHQ vm has another NIC (176.x.y.z) on the backup network (no NAT), and it is this IP that is shown.

Also, can SAN-HQ work in a NAT's network estate, especially as it uses SNMP to poll, and the individual members (195.171.x.y/214.121.x.y) are not directly accessible from SAN-HQ (UDP 161).

Thanks
