Q: Which ports I must open on Firewall to grant telnet access from remote connection ?

A: EVE is using ports starting from 32768

Formula is = 32768+128*POD+1 -> 32768+128*POD+128    POD: user id ( admin = 0 )


Exemple: you got admin (POD 0) + 2 users ( POD 1, POD 2 ) 

32768+128*0+1(First port for POD0)   -> 32768+128*2+128(Last port of POD 2 ) = 32769 -> 33152

Port for Dummies:

POD First Port Last Port
1 32769 32896
2 32897 33024
3 33025 33152
4 33153 33280
5 33281 33408
6 33409 33536
7 33537 33664
8 33665 33792
9 33793 33920
10 33921 34048
11 34049 34176
12 34177 34304
13 34305 34432
14 34433 34560
15 34561 34688
16 34689 34816
17 34817 34944



so,...simple mathematics.
