There are always questions how to place your F5 GTM and LTM. Different situation has different solution design. Here are some simple examples when I used to explain the location of LTM/GTM.

1. LTM only (Without GTM)

The devices order should look like this: 

Internet —> Router —> Firewall —> F5 LTM  —> DMZ Servers

or

Firewall Sandwiches:
Internet —> Router —>F5 LTM  –> Firewall —> F5 LTM —> DMZ Servers

2. LTM With GTM

2.1 GTM in your data center

2.2 GTM outside of your data center
