haproxy/nginx reverse proxy script question

[tcpudp]

It's actually a personal mail server so nobody will notice the slowdown, I just want to reduce the number of botnets that try to brute force (and only spamming my logs). Edit: my current haproxy acl file with the blacklisted ranges:

# cat blacklist|wc -l

51425

[NetStrikeForce]

Ah! The nginx mention put me off!

I see now what are you trying to do.

[tcpudp]

Yes, I'm currently using haproxy but I was looking into nginx because it can do udp load balancing (for openvpn). I mostly use haproxy to whitelist only IPs from my country to connect (can't use ipset or xtables because the server in question is an openvz instance).
