   • F5 Load balancer over web server

     Top Answer

     Answered Mar 29, 2016 · 1 votes

     Following up on Jason's comment, if you're serving up publicly consumable content, you should use Apache. Your developers would normally not have access to the BIG-IP so any content management requirements would be hindered by placing publicly served pages on the BIG-IP.

     If you're only using BIG-IP for rewrites, redirects, traffic manipulation, and any SSL/TLS management, BIG-IP would be an appropriate place for this as long as your dev teams don't require frequent management of these functions.

     This is really an opinion question but standard practices do host web servers behind the BIG-IP for content layer presentation.

   • F5 Load balancer client IP in webserver

     Top Answer

     Answered Jan 04, 2017 · 2 votes

     This typically depends on whether a proxy/firewall is in the path of ingress and egress traffic.

     Majority of the time incoming traffic to a webserver will hit a configured SNAT before reaching the virtual IP address of the interface associated with the webserver. In this case, the webserver would potentially be part of other severs in a pool. In this type of setup, a webserver will see the request as coming from the SNAT pool.

     Another type of setup is known as "Pass Through" which is configured using the FastL4 virtual server type. F5 recommends to use FastL4 only when your virtual servers "will not" be processing anything past Layer 4, this causes the load balancer to process a bit faster.

     But to get back to your question, there is also the x-forwarded-for option in which the F5 inserts the "original client IP address in an http header", and in this case the receiving web server must be configured to log/recognize this client IP address and bypass the SNAT pool option.

   • F5 Load Balancer Persistence Profile How to determine Timeout setting Value

     Top Answer

     Answered Aug 08, 2018 · 1 votes

     Persistence timeouts should be slightly larger than the applications session timeouts. You are correct. The persistence timeout will start once the session goes idle (no traffic). The session persistence timer countdown will reset if traffic received. If it expires, the LB method is reapplied and the session will be most likely be routed to another server (there are ways around this but by default this is how it's supposed to work).

     The standard default timeout is 300 seconds but should be bumped up to over 20 minutes if your application times out at 20 minutes.

     This can get dangerous with source affinity specifically when client/source connections aggregate over a single IP or pool of addresses because multiple client sessions would show up as one session to the persistence profile.

     People can forget that Session != Connection

     Multiple connections coming in as the same IP would technically staple the persistence session up permanently unless the destination server node was restarted. For web applications we recommend cookie persistence so the client can control it's own session. This requires the client to be able to receive cookies.

     This of course is dependent on the application and if you're NAT'ing traffic to BIG-IP. Otherwise, you're off to the races with your correct assumption.

     And Per F5 Support LTM Concepts:

     Source address affinity persistence Source address affinity persistence, also known as simple persistence, tracks sessions based only on the source IP address. When a client requests a connection to a virtual server that supports source address affinity persistence, Local Traffic Manager checks to see if that client previously connected, and if so, returns the client to the same pool member.

     You might want to use source address affinity persistence and SSL persistence together. In situations where an SSL session ID times out, or where a returning client does not provide a session ID, you might want Local Traffic Manager to direct the client to the original pool member based on the client’s IP address. As long as the client’s source address affinity persistence record has not timed out, Local Traffic Manager can successfully return the client to the appropriate pool member.

     Persistence settings apply to all protocols. When the persistence timer is set to a value greater than 0, persistence is on. When the persistence timer is set to 0, persistence is off.

     The persistence mask feature works only for virtual servers that implement source address affinity persistence. By adding a persistence mask, you identify a range of source IP addresses to manage together as a single source address affinity persistent connection when connecting to the pool.

Sabaris, Either one of these should work, though I believe the second one consumes less resources due to the switch statement. The 'string tolower' doesn't have to be in there, though it could also be in both, just depends how you want to do it.
