cache-ex oscam to oscam

Hi,

I can't connect with cache-ex two oscam sides.

With group = 1 have x active lines coming from cccam servers.

First i have this case

**********
server_a
**********
oscam.server

[reader]
label = usera
enabled = 1
protocol = camd35
device = ip_server_b ,12345
user = oscam_b
password = oscam_b
group = 1

**********
server_b
**********
oscam.conf

[cs357x]

port = 12345

oscam.user

[account]
user = oscam_b
pwd = oscam_b
group = 1
au = 1
keepalive=1

with this configuration everything is ok, i get ECM's ok.

but when i try to use cache-ex i can't get any ECM's.
i can't connect with both oscam sides.

**********
server_a
**********
oscam.server

[reader]
label = oscam_server
enabled = 1
protocol = camd35
device = ip_server_b,12345
user = oscam_b
password = oscam_b
cacheex = 3
group = 1
dropbadcws = 1


**********
server b
**********
oscam.conf

[cs357x]

port = 12345

oscam.user

[account]
user = oscam_b
pwd = oscam_b
group = 1
uniq = 3
cacheex = 3
cacheex_maxhop = 3
allowedprotocols = camd35

with this configuration i can't get nothing,

on server_a i get status UNKNOWN on server_b i get oscam_b offline.

I would be appreciate with some your help,

Pinky
