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.
Of course you have to be sure open ports 80(443 if you use SSL) and 22.
