Hi to all,
I'm trying to configure my Database Firewall in DPE mode (In-Line).
Bellow are my configurations:
Target Oracle Database:
IP:192.168.43.100
Mask: 255.255.255.0
Gateway: 192.168.43.1
My Client:
IP:192.168.43.110
Mask: 255.255.255.0
Gateway: 192.168.43.1
Database Firewall:
Management IP:192.168.43.212 --> Formed with one VirtualBox NIC (eth0)
Mask: 255.255.255.0
Gateway: 192.168.43.1
Bridge IP (br0): 192.168.43.220 --> Formed with two VirtualBox NIC (eth1 & eth2)
Audit Vault:
IP:192.168.43.210
Mask: 255.255.255.0
Gateway: 192.168.43.1
Before setting the DPE mode my Clients can connect remotely to the secure Oracle database but once I enabled the Bridge from the Database Firewall and setting the DPE mode, my Client cannot connect to the secure Database saying (ORA-12547: TNS:lost contact) and I'm getting the following error from the (/var/log/messages) of the Database Firewall server:
