Cisco RV345 DMZ configuration

Hi,

 

We have this network configuration in RV345:

 

WAN1: 

ip: 192.168.1.11 /24

 

VLAN1

ip: 192.168.3.11 /24

 

Hardware DMZ 

Enabled (port 16 to DMZ)

ip: 192.168.2.11

mask: 255.255.255.0

 

DMZ Host

Enabled

ip: 192.168.2.11

 

I'm trying to allow traffic from DMZ to Internet but I can't, ping to 8.8.8.8 not responding from a computer in DMZ with 192.168.2.100 ip.

 

The access rules (basics for test) i have configured:

 

DMZ to WAN1 - All traffic - Source: any - destination: any - Allowed

WAN1 to DMZ - All traffic - Source: any - destination: any - Allowed

 

But this configuration is not working.

 

What am I missing?

 

Thanks!

 

Julen.

Yes, from the host 192.168.2.11 (this host is RV345 firewall on the DMZ port) i can ping 8.8.8.8 but from a computer behind firewall DMZ I cannot.

 

Thanks for reply.

Sorry not familiar with RV345s. Just try to help from guides.

Maybe try - 

3. Select Subnet to identify a subnetwork for DMZ services and enter the DMZ IP Address and Subnet Mask.
4. Select Range (DMZ & WAN within the same subnet) and enter the IP range
 
The host in DMZ host is working as expected, right? 
Maybe add the range from the DMZ subnet as well.

I think the issue is in the Firmware because I've disabled the Hardware DMZ and created an VLAN with subnet 192.168.2.11/24 in the 16 port and limited the acces with rules like DMZ and it works. For that reason I think the problem is in the Firmwar and how it manage the DMZ port, I think there is a problem with the NAT o Routing between LAN/WAN ports and the DMZ port.

If you have valid Cisco contract, please raise a case with Cisco TAC and they will be able to confirm.

Sorry, could not be more helpful.
