Right now I have:
- eth0: LAN -> Masq to the UTM's public IP
- eth1: WAN -> public IP range
- eth2: DMZ -> NAT range 10.24.1.1/24
I've set up my first DMZ host on the eth2 switch with a 10.24.1.* address and a DNAT rule from its WAN IP -> NAT IP. I can access the NAT host by its public IP from my LAN and the NAT rule appears in the firewall log since I have "log initial packets" set for the DNAT rule.
The problem, however, is that when I try to access the DMZ host by its public IP from an external source I can't connect and no firewall logs appear, neither NAT confirmations nor firewall blocking logs. Since there's no feedback from the firewall, I kinda think that it may be a routing issue, but I don't know how to check or troubleshoot that.
Any ideas or further troubleshooting steps?
