So an app I wanted to check out in alpha requires docker. So I spun up a debian VM and installed docker followed by the app.
The app appears to be working but I see a major amount of blocked traffic at the pfSense firewall for 172.17.0.2 trying to send TCP:R traffic. I believe TCP:R would be the reset. and the state table is rather large as nothing is resetting…
The server has a 192.168.5.2 address
Docker created the docker0 network with 172.17.0.2 as expected
The iptables NAT default was this:
and they should show no traffic from 172.17 only traffic from 192.168.5.2 and that is why the firewall is dropping it.
I tried to change the iptables but no luck.
I don’t know anything about the mechanics of the app and docker use, I started in the app forum and now I am here as I think it is a docker NAT issue or my server issue that someone who knows docker could help me with… I think something is wrong with the mask
Thanks in advance…
