NAT IPv4 Help Page


The services offered on Gullo NAT are unmanaged i.e. self managed (By You). This allows the price to remain low.

This page will offer some general advice and help to get you started.

Connecting to your new server

If you are lucky enough to have native IPv6 or are already running a tunnel then you can simply connect via your IPv6 address just as you would do usually via IPv4.

If you do not have native IPv6 or a tunnel then it is suggested you consider getting an IPv6 tunnel. This page will not cover this as many online guides and places to get a tunnel set up already exist such as:

Options do exist for connecting over IPv4 such as DNAT port forwarding and console connectivity. In one of the first emails you get from us after signing up, you will find details on which ports have been configured to forward IPv4 connections to your VPS; one of which will be for SSH connectivity.

The final option for connecting will be via the virtual console connection. You can use this via the SolusVM control panel or direct connect via SSH using your console username and password - provided again via SolusVM.

So how can I host a website if I do not have a dedicated IPv4 address?

Cloudflare runs a free IPv6 to IPv4 proxy with their service. Cloudflare's CDN normally works on a reverse proxy (you publicly see a Cloudflare IP for your site, while it proxies your actual IP to load your site).

1) Signup for a free account at and add your domain (you can add as many as you want)
2) Update your domain's name servers at your registrar to the ones Cloudflare supplies (<name>
3) Edit your Cloudflare DNS records, create & point your domain/subdomain's quad-A (AAAA) record to one of your LES IPv6 Addresses (see your welcome email with your VPS info)
4) Make sure you have "Cloudflare On" for the domain/subdomain record you just setup (make sure the little cloud icon is orange next to the record)
5) Head into your "Cloudflare Settings" for your domain - select the gear icon next to your domain in the main domain list
6) Scroll down and under 'Automatic IPv6' change the default mode 'Safe' to 'Full'
7) Modify your web server to listen on the IPv6 address you used above, on port 80 of course


What limitations can I expect?

With private addresses we cannot set rDNS records for IPv4 and only in some cases will we be able to do this for IPv6 - so email services may not be a reliable option, and in some locations email may be blocked completely to avoid abuse.

If you install software that requires specific ports in order to run, this may not be viable over IPv4.

What support is offered with this service?

In a nutshell, very little. It is not intended for novice users or those who are unwilling to learn new things.
