How to forward to multiple ips in dante server?

Question

linux

I installed dante server on virtulbox and made the following settings in dante.conf:

logoutput: /var/log/danted.log
internal: 0.0.0.0 port = 4246
external: enp0s8
socksmethod: none
clientmethod: none

user.privileged: proxy
user.unprivileged: nobody

user.libwrap: nobody

client pass {
        from: 0.0.0.0/0 to: 0.0.0.0/0
        log: error connect disconnect
}

socks pass {
       from: 0.0.0.0/0 to: 0.0.0.0/0
       log: error connect disconnect
}

route {
 from: 0.0.0.0/0 to: 0.0.0.0/0 via: 94.181.48.110 port = 1256
 proxyprotocol: http_v1.0
 command: connect
}

Now I can connect from my laptop via socks5 proxy to the virtual machine in firefox on port 4246 and the ip in the browser will change to 94.181.48.110. But I want to be able to use multiple different ip's. For example: When I connect in the browser on port 4247, then the ip changes to 94.181.48.110, and when I connect to 1080, the ip will be 191.101.39.20. All settings must be written in one file.
