    Hi,

    My network setup is as follows:

    ISP supplied modem/router model: Vodafone H-500-t - 192.168.0.1, DHCP on

    TPLink TL-WR1043ND - 192.168.1.1 - DHCP on - plugged in to 192.168.0.1

    File sharing server - 192.168.1.8

    Various WiFi devices connecting to networks on both devices. Desktop plugged in to 192.168.1.1.

    I want to point a domain I own to my file sharing server. My modem/router can only port forward to addresses on the same subnet, and my router tells me it can't be on the same subnet as the WAN IP address.


    I'd appreciate any tips, happy to try new network configurations etc. Please let me know if I can provide more info.

    Cheers.

    The proper solution: only have one router betwix you and your ISP. Is there a reason you're running both, rather than routing through the Vodafone and using the TP-Link as a simple wireless access point?

    If you don't want to change that, then you'd need to forward the required ports from the Vodafone to the TP-Link, then from the TP-Link to your fileserver. And cross your fingers.

    You'll need to figure out what ip address your TP-Link is using as it's WAN address and then port forward to that on the Vodafone. You'll also need to port forward on the TP-Link to your file server.

    As Gareth said though, double NAT is generally not a good idea.
