Hello!

I have iptables config like this:

iptables -F INPUT
iptables -F OUTPUT
iptables -F FORWARD

iptables -P INPUT DROP
iptables -P OUTPUT DROP
iptables -P FORWARD DROP

iptables -A INPUT -p tcp --dport 22 -j ACCEPT
iptables -A OUTPUT -p tcp --sport 22 -j ACCEPT

iptables -A INPUT -p tcp --dport 80 -j ACCEPT
iptables -A OUTPUT -p tcp --sport 80 -j ACCEPT

iptables -A INPUT -p tcp --dport 443 -j ACCEPT
iptables -A OUTPUT -p tcp --sport 443 -j ACCEPT

Also, I have apache virtual host:

<VirtualHost *:80>
    ServerName wiki.myite.com
    <Proxy *>
        Order deny,allow
        Allow from all
    </Proxy>

    ProxyPass / http://localhost:8901/
    ProxyPassReverse /  http://localhost:8901/
    <Location />
        Order allow,deny
        Allow from all
    </Location>
</VirtualHost>

My primary domain www.mysite.com is working well with this configuration (I don't use proxy redirect on it). But my virtual host wiki.mysite.com is not responding.

Please, help me to setup iptables config to allow wiki.mysite.com working too. I think, I need to setup iptables FORWARDING options, but I don't know how.

update:

I have 1 server with 1 IP. On server I have apache2.2 on 80 port. Also I have tomcat6 on 8901 port. In apache I setup to forwarding domain wiki.mysite.com to tomcat (mysite.com:8901).

I want to secure my server by disabling all ports, except 80, 22 and 443.
