I think you need to explain exactly what you are trying to set on the SuperHub that leads to this error, because on the face of it what you are doing is really straight forward.

On the SH2, set the SH2's LAN IP to 192.168.x.1 (I would always use .1 rather than .2 for the SuperHub) in DHCP Settings and the Draytek to 192.168.x.2 in DHCP Reservation, for example.

On the Draytek, you then setup your Draytek as a router on a different subnet (if x=2, then the Draytek subnet could be 192.168.0.* or 192.168.1.*. With the normal issues around double nating this should work fine.

This should all "just work", so it sounds like you are getting confused somewhere and it would help if you spelt out exactly what you are setting and where.

But the reason people are replying some what quizzically to this question is because what you are doing is not at all, in your words, "common". There are two things people commonly do:

- Use another router altogether. Here they put the SuperHub into "modem mode" and don't use the superhub' firewall or WiFi at all

- Use the SuperHub as the router and firewall but extend their network by using a second router as an "Access Point" (AP). Here the second device (eg. Your Draytek) has its firewall and its DHCP server disabled (either by explicitly settings "AP Mode", or by manually disabling them, and is assigned a static IP on the same subnet as the rest of the LAN. The AP provides 3/4 more LAN ports and another WIFi network to reach the parts the SuperHub cannot reach

You seem to be trying to use the Draytek to provide a 2nd firewall/NAT, but only for some devices (not those that connect directly to the SuperHub by Ethernet or WiFi) and maybe a 2nd wifi network. This is very unusual and could cause problems ("double NATing" is not generally a good idea). But, double NAT issues aside there is no reason why what you are doing should simply "not work". I'd recommend you decide either to use your Draytek as a router/firewall, if not happy with the SH2's, leave it on all the time and put the SH2 into modem mode, or use the Draytek as an AP to provide extended wifi and more ports. Ethernet switches are dirt cheap these days if you just need more LAN ports. But if you really want to do things your way it should be really easy, so tell us exactly what you are doing on the SH2 and I'm sure it can work.
