Hi,
I just want to connect with one of my mail servers through css11501
this is my config
-------begin-----
!************************** CIRCUIT **************************
circuit VLAN1
ip address 195.xxx.xxx.xxx 255.255.255.248
no redirects
ip address 10.1.1.1 255.0.0.0
no redirects
!************************** SERVICE **************************
service mx01
max connections 1024
ip address 10.0.2.3
port 25
protocol tcp
active
!*************************** OWNER ***************************
owner mx
content mx-con
add service mx01
protocol tcp
vip address 195.xxx.xxx.xxx
port 25
!*************************** GROUP ***************************
group mx-group
vip address 195.xxx.xxx.xxx
add service mx01
active
----------end---------
but when I connect with 195.xxx.xxx.xxx on 25 port - it writes me "connection refused"
whats wrong with my configuration

as always, the best solution is to capture sniffer traces to figure out what is going on.
From experience I would say you have a one-armed config, and the server response is going directly to the client without going first to the CSS.
I would recommend to remove your line 'add service ...' and replace it with 'add destination service ...'

ok, thank you.
I have another question. I just want to balance load beetween my five mail servers (they are just relays).
Is it possible ?
I look through "CSS Content Load-Balancing Configuration Guide" - but did not found any solution in it. All examples are about WWW. But now I need to balance my heavy loaded mail. And onle after -- balance WWW.

you can balance almost everything.
For WWW you get more functions that let you check the content, but for email traffic, you can simply balanced based on destination ip and tcp port.
Just make sure the response from the server is coming back to the CSS and does not go directly to the client.
[with client nat on the CSS or pointing your default gateway to the CSS]
