comment Server A can see B, but B can't see A
Your IP configuration is either very incomplete or doesn't make sense at all with the 10.145.255.254 address (which isn't in the same block as 10.10.10.x and 10.10.20.x) and the 255.255.192.0 netmask (which would cover both these two blocks). If the BigIP can't ping the server, check for IP misconfiguration, firewalling on the host, routing on both host and BigIP. But if you really want some help on this, please update the original question with some real information, like the IP addresses, BigIP config (type/version, self IPs, ARP, routes, SNAT/DNAT config), because it's all just guesses now.

comment Upgrade HTTP connection to SSL/TLS
Changing from HTTPS to HTTP when a certificate isn't correct it something you should never want to happen as a visitor. The fact that a certificate is incorrect should be a sign that's something wrong, reverting to an unencrypted connection is the worst thing you could do then. The best solution you have is to fix your certificate so it matches your hostname(s), either by using another CA or by not using SNI.

comment Is it possible to schedule a python script to run at the end of logrotate?
That totally depends on how the script works (which I'm not familiar with). The script is executed after all logs are rotated, what exactly it does and with what logs is entirely up to the script.

comment postfix setup: relay access denied. Help me understand
If you're only using postfix to send out mail, relay_domains should be empty. You need to fix the netmask in my_networks to your actual local network to have postfix accept mail from those IP addresses.

comment DDOS using ntp server
Fair enough, mentioning noquery would have been a good addition. My other problem with your Cloudflare remark was that you used those posts as if that's the only way NTP is abused. That part has nothing to do with Cloudflare itself. But perhaps I shouldn't have spoken about Cloudflare's motives.
