I’m having issue making a container running in the network of gluetun to access the host.
In theory there’s a variable for this: FIREWALL_OUTBOUND_SUBNETS
https://github.com/qdm12/gluetun-wiki/blob/main/setup/connect-a-lan-device-to-gluetun.md#access-your-lan-through-gluetun
When I include 172.16.0.0/12 I can ping the ip assigned with host-gateway but I can’t curl anything.
The command just stays like this until it timesout
# curl -vvv 172.17.0.1
* Trying 172.17.0.1:80...
I also tried adding 100.64.0.0/10 to connect to tailscale but is the same response, can ping and timedout curl.
Any other request works properly connected via the VPN configured in gluetun
Do you guys have any idea what I might be missing?
Found the issue '^-^
UFW also blocks traffic between docker and host.
I had to add these rules
ufw allow proto tcp from 172.16.0.0/12 to 172.16.0.0/12 port 80 ufw allow proto tcp from 172.16.0.0/12 to 172.16.0.0/12 port 443
