Greetings:
I run firefox in an LXD container (Ubuntu 20.10) on a host running Debian 11. I would like to institute UFW on the host however everytime I enable my firefox browser (in the lxd container) can no longer connect to websites. Here are my pertinent UFW rules:
To Action From
-- ------ ----
[ 1] 56216 ALLOW IN 192.168.86.0/24 # LAN to SSH
[ 2] 56216 ALLOW IN 192.168.87.0/24 # wg0 to SSH
[11] plexmediaserver ALLOW IN Anywhere
[12] 10.9.21.0/24 on lxdbr0 ALLOW FWD Anywhere on enp42s0
[13] Anywhere on lxdbr0 ALLOW FWD Anywhere (out)
[14] 192.168.86.0/24 on vethea2ddd10 ALLOW FWD Anywhere on enp42s0
[15] 192.168.86.0/24 on veth95e57722 ALLOW FWD Anywhere on enp42s0
[16] Anywhere ALLOW OUT Anywhere on lxdbr0 (out)
[17] plexmediaserver (v6) ALLOW IN Anywhere (v6)
[18] Anywhere (v6) on lxdbr0 ALLOW FWD Anywhere (v6) (out)
[19] Anywhere (v6) ALLOW OUT Anywhere (v6) on lxdbr0 (out)
Rules 3-10 are rules to block access to certain public IPs from ANY.
My /etc/ufw/sysctl.conf in pertinent part:
net/ipv4/ip_forward=1
net/ipv6/conf/default/forwarding=1
net/ipv6/conf/all/forwarding=1
lxdbr0 is the bridge that the Firefox container uses.
Any ideas? Thank you!
