Network bridging not properly enabled
Elfinhope opened this issue · 3 comments
On running of the playbook, I got two errors related to network forwarding. First, /proc/sys/net/ipv4/ip_forward was not set to 1 and second /proc/sys/net/bridge/bridge-nf-call-iptables did not exist. Both were easily solved the first by uncommenting the appropriate line in sysctl.conf and the second by running modprobe to load br_ipforward (I also added net.bridge.bridge-nf-call-iptables=1 to my sysctl.conf file as well).
I have Raspbian 64-bit lite (I believe Bullseye) on Pi 4s. I've used this playbook previously and did not have this problem, so there must have been some change when Bullseye came out.
Note, the modprobe above should have been br_netfilter not br_ipforward. In addition, I had to add br_netfilter to my /etc/modules file.
