Yes it is normal and yes it "could" cause problems because you are double nating. The reason why modem mode was created was to disable the router function of the shub. You expect routers to have certain features and perform a certain way and shub1 was made on the cheap and poorly tested and just didn't work. Apart from the wifi being diabolical, it kept crashing when put under moderate load, random reboots, I can remember people have problem with playstations not connecting all that kind of stuff. They were stupid faults that just shouldn't happen. Modem mode was created so your 3rd party router could serve as your primary router and handle everything in it's entirety such as dhcp leasing, wifi and all the routing (obviously) and the shub served as a gateway and passed off all the data to the internet/VM.

Shub aside, you can daisy chain as many routers as you want but you are just asking for trouble. At the moment your 3rd party router has not got a wan ip address and instead a local address provided by the shub. As an example, the ip addressing scheme I use on my router is 18.19.1.100/24 so all the devices on my network start with that address but the wan ip address for my router is the proper internet address I get from VM which is 82.215.xxx.xxx. At the moment your proper router isn't directly connect to the internet and it's wan ip address is the local address the shub has given it (along with all other devices) and will probably be 192.168.0.2 (the shub being 0.1). What happens is that your proper router tries to sort the traffic out itself and instead of sending it straight off to the internet if it needs to, it now has to send it to the shub. It will say "we need to route this traffic to 192.168.0.1 (the shub) and then you hope the shub will look at it and say "we need to send this off to an ip address on the lan (for devices directly connected to the shub) or off to 82.xxx.xxx.xx for the internet". It is also a right pain in the bum if you ever need to do port forwarding as well. I have got two additional routers which I use as wireless access points but that is it. All the routing and dhcp etc is still run by my primary router.

Tbh there really isn't a need to daisy chain routers on your small home networks, especially when the shub is involved. If you need to add more wired devices you are better using switches.
