Yes i want to block all traffic not going through proxy ,

Lets say they are going to that, so those rules don't trigger.  Then looks like everything would hit that first limiter rule.  When would it ever see the 2nd limiter rule?

Currently not using
Previously it was like source IP in range  192.168.1-10-150  = First limiter  .
Source IP in range  192.168.1.151-192.168.1.200 =Second Limiter for Mobile devices

thank you so i am guessing everything is okay as i expected

Might be easier if actual screenshot vs some ascii art, what exactly is  icpv4tcp/udp

As to your block ! (not) that would pretty much block anything not going to what is that alias, guessing that is your proxy..  So if traffic not going there then rules stop evaluating..  And would never see any of the other rules.

Remember top down, first rule to fire wins - rest of the rules after that are meaningless.  The only time you get to the bottom is if none of the rules fire.  If no rules fire, then you hit the default block.

But the default any any would let everything not blocked above that through.
