Socks.conf with two socks servers?

Hi,

We have a setup with Linux hosts on two locations and use dante socks
1.19 to connect to the internet for protocols other than HTTP and FTP.
The following socks.conf route is working:

route {
from: 0.0.0.0/0
to: 0.0.0.0/0
via: 10.0.0.16 port = 1080
protocol: tcp udp
proxyprotocol: socks_v4
method: none
}

What I would like to have is a socks.conf that configures the socks
client to use the nearest socks server, depending on the network. I
tried this without luck:

route {
from: 192.168.1.0/24
to: 0.0.0.0/0
via: 10.0.0.16 port = 1080
protocol: tcp udp
proxyprotocol: socks_v4
method: none
}

route {
from: 192.168.94.0/24
to: 0.0.0.0/0
via: 192.168.94.18 port = 1080
protocol: tcp udp
proxyprotocol: socks_v4
method: none
}

The error debug output says:

Dec 4 14:32:28 adnws001 ftp: Rconnect(): unsupported address family
'10', fallback to system connect()

I did not find such an example in the dante socks distribution or with
Google.

Thanks in advance for help

Regards,
Bernd
