Network services filter limit?

[Marko Polo]

Hi there,
Am I right here, assuming that this filter in Merlin is unlimited, and we can add any number of rules via iptables?
I am speaking particularly about AC68U.

I don't know whether it's different in Merlin's, but in John's fork at Firewall > Network Services Filter it says "Network Services Filter Table (Max Limit : 128)"

In my applet it says Max Limit : 32 That's why I ask this. And what it John's fork ?

It's a fork of Merlin's firmware based on older code. But it's not available for the AC86U.

But it's not available for the AC86U.

Why?

The following routers are supported:
AC68U (Rev A1,A2,B1)

Maybe I have the proper revision. How to check it?

Because you said you had the AC86U, not the AC68U (which is supported).

Mea Culpa! It was a typo.

And can smb say smth about this limitation in Merlin? Does this limit exist or rules are unlimited?
Network services filters are based on iptables, no?

 

[RMerlin]

The limit is also 128 entries. The problem isn't iptables, but the firmware itself, which has to store this list in nvram, and also process it when building the firewall rules.

Thanks for clarification.
