I have apf installed on a OpenVZ container (proxmox 2.1). The config is pretty much vanilla and things are working. My external services like ssh and http are working. My problem is that all outbound traffic on http/https is blocked. How do I allow all outbound traffic for http/https.

If I change EGF to 1 like this, all inbound and outbound traffic gets blocked

EGF="1"
EG_TCP_CPORTS="21,25,80,443,43,53"
EG_UDP_CPORTS="20,21,53"
EG_ICMP_TYPES="all"

I opened a single outbound rule with the following

# /usr/local/sbin/apf -a downloads.wordpress.org

How do I allow all outbound traffic on http/https without blocking all traffic? Why would I allow all inbound ssh/http traffic and block all outbound traffic?

I was thinking initially needing to do a reverse proxy or something so I could get some SSL/TLS traffic look like it is being terminated at a server and IP address in the AWS cloud, and then that traffic is forwarded onto our actual web servers that aren't in the cloud... I've not done much iptables… >>> More

Managed hosting firewall vs managing own firewall

I posted on stackoverflow as to the overall benefits of managed hosting vs non-managed hosting. The more I think about it, it seems to boil down to one question: should I use a managed host because they take care of the firewall, or would I be okay managing my own, software firewall?
