I have installed 5 LXC containers in Proxmox. Each container has a Apache2 webserver up and running inside, pointing to a registered domain.
So:
container1 points to example1.com and has a local ip address of 192.168.2.225
container2 points to example2.com and has a local ip address of 192.168.2.230
container3 points to example3.com and has a local ip address of 192.168.2.235
and so on.
I would like to forward requests for the 5 different domains to the according container. All containers have static ip's and are bridged on vmbr0 to the physical NIC (enp3s0)
So I tried to achieve it with a separate container, running Squid proxy,with a local ip address of 192.168.2.253 and port 3128, which is Squid's default listening port.
First I had setup iptables on the Proxmox host with the following rules:
iptables -t nat -A PREROUTING -i vmbr0 -p tcp --dport 22 -j DNAT --to 192.168.2.253:3128
iptables -t nat -A PREROUTING -i vmbr0 -p tcp --dport 80 -j DNAT --to 192.168.2.253:3128
iptables -t nat -A PREROUTING -i vmbr0 -p tcp --dport 443 -j DNAT --to 192.168.2.253:3128
iptables --t nat -A POSTROUTING --out-interface vmbr0 -j MASQUERADE
After that I tried to configure Squid:
http_port 3128
http_access allow all
http_port 3128 intercept
visible_hostname squid.proxy
acl 100 dstdomain .example1.com
acl 101 dstdomain .example2.com
acl 102 dstdomain .example3.com
cache_peer 192.168.2.225 parent 80 0 no-query
cache_peer 192.168.2.230 parent 80 0 no-query
cache_peer 192.168.2.235 parent 80 0 no-query
When browsing to example1.com, I am notified by Squid with the message:
The requested URL could not be retrieved
My question is: what can I do to forward each domain successfully to it's according container?
