Proxy SSL Client Certificate through NGINX Load-Balancer

The frontend stream proxy_pass can be used for load-balancing without SSL off-loading. All SSL connections will be terminated on the backend and client certificate information can be properly authenticated.

This should be used in cases:

• you have enough CPU to decrypt SSL on the backend servers
• you require direct client AUTHENTICATION on the backend servers

def ip2hex(cidr, router):
    addr, mask = cidr.split("/")
    mask = int(mask)
    addr = [("%2s" % hex(int(i))[2:]).replace(" ", "0") for i in addr.split(".") if i != "0"]
    parts = mask/8 - len(addr)
    if mask%8 > 0:
        parts += 1
    if parts > 0:
        for i in range(int(parts)):
            addr.append("00")
