RV340W DMZ Problem

[jfdufour]

Hi,

I'm experiencing some problem to configure my dmz with a rv340w. I aleady setup many dmz with other brand of router but first time with de cisco rv340w.

LAN : (not the same ip but same setup)

IP Range : 10.10.10.2 / 150
Subnet : 255.255.255.0

Gateway : 10.10.10.1

So for the LAN basic setting and WIFI all work good, awesome router for the price.

I activated the Hardware DMZ option and configure it with the ip 10.10.11.1 and subnet mask as 255.255.255.0. As soon I activate that we can ping 10.10.11.1 from the lan and dmz. So the interface was created by the router (the port LAN4 was converted to DMZ Port).

After I configured the access rules, so I allow wan1 to dmz and allow dmz to wan1 for anyting (test only not the final setting). Its not the full rules I want to configure but supposed to work with only those 2 rules. But a computer on the dmz can ping 10.10.11.1 but are unable to navigate internet, there is my problem is miss something on the configuration and need help to find my problem.

Thanks

I had the same issue but I resolved it by changing the DNS on the PC/Server NIC to point to the DMZ interface.

I have the same issue too !

Problem solved. The DMZ configuration should be the static IP provided by your ISP. On the Server/PC and the Router.

[ramiro88]

Yes

I did that. public..public..ip but it is not working.

[mkelleyenc]

WAN, Hardware DMZ Range (DMZ &WAN within Same Subnet) IP range Static IP 10.10.10.10 to 10.10.10.10

Substitute for your Static IP



Firewall DMZ Host Enable enter static IP



Make sure the IP address is not port mapped, port forwarded, port triggered, or in the static NAT table.

4. Firewall access rule add

    - allow any DMZ -> WAN1 (OK)

5. Port Connect: LAN4-Windows server 2019 NIC #1

Status

Check ICMP state on RV340 and Windows Firewall config.

Allow inbound and outbound for ping test.
