Connection Tracking 'Max-Entries' property

RouterOS General
1

Today I’ve increased amount of RAM on x86-based router, from 256 to 512 MB.
With 256MB of RAM ‘Max-Entries’ value was 443100.
With 512MB of RAM I’ve expected that this value will be doubled, because Wiki says:
http://wiki.mikrotik.com/wiki/Manual:IP/Firewall/Connection_tracking#Properties_2

max-entries (integer) Max amount of entries that connection tracking table can hold. > This value depends on installed amount of RAM.

But now ‘Max-Entries’ value is 524288 (512k).
So my questions are: Does it depends on installed amount of RAM, but there is also hard-coded limit (512k)?
Did you ever seen this value greater than 524288 (512k)?

Thanks in advance,

Hi, RB1100 with 1Gb shows same : P!

Hi Martin,

Thanks for your answer.
It clearly shows that ‘max-entries’ limit is hard-coded to 512k.
