Double NAT - can i get around it in this scenario?

[nad_isa]

Calling all network engineers, gurus, self taught maestros...need some help.

So after some considerable time i have setup my RB4011 to work with my fibre connection. I am new to mikrotik and not experienced in networking concepts (i know how to fiddle, follow instructions etc).

So i have a vumareach (VR) fibre connection which comes with an all in one cheapo ONT/Router. Problem is, this ONT/router is completely locked down - no access to any settings whatsoever and vuma have no intent on assisting.

So no bridge mode, no ip passthrough, no DMZ functions. you cant even switch off the wifi, DHCP, etc. All they have is a bespoke portal to change your wifi password. (why they do this and how crappy it is, is for another discussion )

The router sits on the 192.168.18.x range with the router IP on 192.168.18.1.

I have setup my router from port 1 of the VR router to the mikrotik and setup a basic connection using quickset. the problem i have is this causes double NAT.

is there any way to get around this? (besides getting another ISP/internet service - no option)

Have you considered using a VPN to tunnel through the NAT?

I can assist you with the NAT on the mikrotik but thats not gonna get you very far if the other router is also doing the same thing.

Lol yeh, wanted to see who is the cleverer bunch. But you right. No miracles for me..

I have a similar issue with a Rain CPE and an old Apple Airport Express. Funny enough the Airport is clever enough to realise the double NAT and automatically switches to bridge mode...

There is no way of bypassing ISP NAT'ing. And no High end ISP will provide any custom port forwarding configuration unless you buy a static IP for an additional charge.

The only way to get through it is client side VPN client and a cheapo, data centre server in VPS format.

That will guarantee your connection with port forwarding on a Centos Server.
