I have a container setup with LXD running several wordpress webpages (apache2)
All is working fine.
I added portforwarding by:
lxc config device add CONTAINER lxd_proxy_port80 proxy listen=tcp:0.0.0.0:80 connect=tcp:INTERNALIP:80
…and same for port 443. Thats all working correctly.
Unfortunately I cannot see originating IP’s in my apache2 logs (var/log/apache2/access.log) but only see the local IP.
By using iptables I wanted to change this. I did:
iptables -A FORWARD -p tcp -d LOCALIP --dport 443 -j ACCEPT
iptables -A FORWARD -p tcp -d LOCALIP --dport 80 -j ACCEPT
and deleting my proxy device with
lxc config device remove CONTAINER lxd_proxy_port80
lxc config device remove CONTAINER lxd_proxy_port443
I can actually access files on my server correctly and I also see now my external IP in the apache2 access logs.
However, wordpress does not reach update-servers anymore (external) and seems to have problems reaching the outside world and one of my wordpress pages cannot access the index.php file anymore (it hangs loading). I suppose the latter effect is due to some external content not being loaded correctly.
Could you help me understand what is going on?
