Open spiderbit opened 5 years ago
Well I played around a bit with the setup and yes it says filtered, but I mistaken that with "not open" basically, but it works, I can connect with the ssh client.
So my real problem is a deeper one, I have a openvpn client setup inside the container, but I need to connect to a port inside from the local lan.
the port says still filtered, but I think the container finds no route to the lan, not sure if I have to setup some SNAT rule.
Probably it's not nixos specific then.
networking.nat.extraCommands = ''iptables -t nat -A nixos-nat-post -d [CONTAINER-LOCAL-ADDRESS] -p tcp --dport [PORT] -j SNAT --to-source [CONTAINER-HOSTADDRESS]'';
networking.nat.forwardPorts = [
{destination = "[CONTAINER-LOCAL-ADRESS]:[PORT]"; sourcePort = [PORT];}
];
That works with openvpn in the container, you can then remove also the forwardPorts option from the container, because networking.nat.enable does the same.
I would suggest to include that somehow into the networking / container documentation of nixos or automatically add such a iptables chain for every container that contains a services.openvpn.servers.client option.
Or you could have something like containers.
Other than that, this bugreport could be closed.
Is this a duplicate of #28721?

Having the same issue. Any fixes?
Steps to reproduce
$ nmap sshtest -p 22 22/tcp open ssh
$ nmap 192.168.1.110 -p 25 25/tcp filtered smtp
Why does the firewall prevent access onto the service? Why does forwardPort configuration not setup the system that it actually does forward the port?
I think that is a bug if that is a feature I would say it's a bug in the documentation.
with nat.enable = false; it's the same result.
