Hello folks,

Our BBSing experiences in Brazil are being affected by a decision taken by some ISPs a few months ago: Many of them are not offering public IPv4 addresses anymore, which is affecting the capabilities of some systems to be accessed.

That happened with Ninho do Abutre, from our fellow sysop Mauro Veiga.

We are trying to come up with solutions to his issue... The only things I can think of would be migrating his system to IPV6 (if available by his ISP) or establishing a VPN towards another system in the cloud with public IPv4s available.

Has any of you faced a similar issue? Any other things that we can try it out?

Regards,
Flavio.

Howdy,

We are trying to come up with solutions to his issue... The only things I can think of would be migrating his system to IPV6 (if

Both methods would work well...

Have you tried contacting the ISP to explain your situation and require
an exemption? Especially if you quickly throw up an IPv6 tunnel to show
that you're using it that way, as well as for the BBS.

Failing that, VPN seems the best way to go. You might even consider
getting your own VPS and either hosting the BBS there instead of
locally, or use that for your tunnel endpoint. It's an extra cost, but sometimes that's the price of a hobby.

Good luck in finding a suitable arrangement, but check with the ISP
first.

but perhaps IPv6 might be available. I will check...

And? Do they offer IPv6?

I think we'll be seeing more of this. :(

I've only faced it in a self inflicted sense, because of the sheer number of systems I want to be Internet accessible. And both solutions work. I'm fully native on IPv6, and my BBSs are IPv6 reachable. I also run a VPN to route a /16 of IPv4, which I use for select systems. So you can say I'm proof of both solutions being viable.

IPv6 requires either your ISP to provide native IPv6 connectivity (the ideal), or use a tunnel service like he.net. For IPv4, you will need to establish a server somewhere, to act as your VPN router, and use a VPN system like OpenVPN or Wireguard. The VPS provider may only give you a single public IP, but you can then use iptables (assuming a Linux server) to add NAT and port forward to your BBS.

And that illustrates yet another solution - host the BBS on a VPS in the cloud, which will solve your IPv4 issue as well.

No doubt we eill see more of it. I see no reason for the ":(" though.

IPv6 is the future and we have seen that it is very well doable to run a Fidonet node on IPv6 without a public IPv4 address. The list of IPv6 capable nodes has grown to over a hundred and that is enough for critical mass. What should have happened ten years ago will now become unavoidable. With a going rate of EUR 50 for a public IPv4 address providers that have run out of IPv4 will have no choice but to offer IPv6 to their customers.

If you have any IPv4 to spare, better sell it now before the bubble bursts. :-)

Really? The Belgians say is was invented by the Dutch...

It does entrench attitudes and behaviours though.

It's coming sooner or later (here for some of us).

Got plenty, none of it's mine though. My /28 belongs to a networking group, and my /24 belongs to ARDC.

Hmm, not sure what that's about. :P


... How would someone else do it?
