RV042 WAN2/DMZ for Instant Hotspot

    I would like to use RV042 WAN2/DMZ and an AP (DLink DI-524 for now) for an instant hopspot. Here's my settings:

    RV042: DHCP: ON, LAN IP: 172.27.12.1/255.255.255.0.

    RV042: WAN1: PPPoE,
    WAN2: DMZ, IP 172.27.16.1/255.255.255.0.


    DLink DI-424: WAN: 172.27.16.1, Default Gateway and DNS set to 172.27.16.1. LAN: 192.168.0.1/255.255.255.255. CAT5 cable from DLink WAN port to RV042 WAN2.

    However, I am unable to get to the internet from a laptop connected to the DLink. What do I do wrong?

    Please advise. Thanks.

    On the DLink...if you want to double NAT like this..(I'd take the AP approach myself)....enter your ISPs 2x DNS servers on its WAN ports instead of the RV0s.

    Also you have an IP conflict...the RV0 is ending in .1....you need to start your devices at something like .2 and on up......you don't want 2x devices using .1

    I have no problem with the AP approach, for example:

    RV042: WAN1: PPPoE, WAN2 not used.
    RV042: LAN 172.27.12.1/255.255.255.0, DHCP ON, from 172.27.12.100-149.

    DLink: LAN 172.27.12.20/255.255.255.0, DHCP OFF. DLink LAN port to RV042 LAN port. WAN port is not used.

    But I want these two LANs totally seperated, for example, the DLink LAN for kids and their friends. RV042 has no VLAN and I read a post not too long ago that this could be done with the RV042 WAN2 set to DMZ. If so, what IP should I use for the WAN2 in my case?

    Thanks.

    for the Double NAT approach you need to add DLINK Subnet to the Multiple Subnet Setting on the main setup page of the RV042 WebGUI

    To do that..you'll have to flip the WAN IP of the DLink so it's not conflicting...can't have 2x of the same IPs on the same network.

    Hi, Toxic,

    I will try the Multiple Subnet approach. I don't need Double NAT or WAN2/DMZ. Just want two seperate LANs.

    Hi, YeOldeStonecat,

    Not sure I understand "...you'll have to flip the WAN IP of the DLink so it's not conflicting...can't have 2x of the same IPs on the same network".

    Don't think I have conflict IPs, LAN#1 is 172.27.12.1, LAN#2 is 172.27.16.1. Both with subnet mask 255.255.255.0. Do I miss something?

    Thanks.

    Ok, I haven't try this yet, bu it makes sense and should work. A qucik and easy way to use the RV042 WAN2/DMZ for an instant hotspot.

    RV042 Device IP 172.27.12.1/255.255.255.0. DHCP ON, 172.27.12.100-199.

    RV042 WAN1 as is. WAN2 set to DMZ, with IP 172.27.12.24 (or any IP not in DHCP range and not 172.27.12.1).

    Any wireless router: CAT5 WAN port to RV042 WAN2. WAN IP: 172.27.12.24/255.255.255.0. Default Gateway and DNS: 172.27.12.1.
    LAN: 192.168.1.1, DHCP ON. Any computer connected to this router is protected by the NAT. This is good or bad is entirely another story. But the point here is these two LANs (172.27 and 192.168) are isolated by default.
