Suspention plugin - confused on some things

[syadnom]

For example, what's the ucrm_forward_first jump rule for? Script doesn't create a ucrm_forward_first chain.

similarly, what's the point of the jump rules that go to a single entry? That actually ads slightly more overhead because it's 2 rules to process.

Then in NAT there's a number of ucrm_dst nat rules that don't do anything except jump to a non-existent chain.

I'm looking through Suspender.php and I don't see those chains even defined in there.

On a loaded router (rb4011 in this case) by disabling the 3 jump rules and switching the jump targets back to the forward chain and disabling the dst and src nat rules that go to nowhere I save a couple of % CPU.
