Re: F5 configuration help is needed

Hello Sezen,

Basically, we need to accomplish two things with this.  We need to 
ensure traffic hits the F5 on the way in, and traffic hits the F5 on the 
way out. 

As mentioned, there's the option of doing a SNAT, basically making all 
inbound web requests appear to the web servers to be coming from the F5 
itself.   Since the servers respond to the F5 directly, we ensure 
traffic hits the F5 on the way in and on the way out.

Also, you can make the F5 the default gateway for your servers.  That 
way, traffic hits the F5's VIP, gets forwarded to the server, the 
servers respond to the client, but use the F5 as the default gateway.  
This ensures traffic goes through the F5 on the way out.  The F5 uses 
its default gateway (your upstream router or firewall) and forwards the 
traffic onto the client.  The true source IP address of the client is 
preserved in this scenario (it is not in the SNAT scenario).
