testing.<br><br>However, for now as much as I love Squid I need a fast and easy solution, so I decided to<br>use Tiny-proxy transparent proxy instead, where I can simply run the service 40 times in parallel since it is so light.<br>Then, if there is a reboot of the modem, I can simply restart the specific service I need,<br>without effecting the other services and users.<br><br>Of course, this only works if you have a really simple configuration, for example like my case:<br>traffic from port 8001 -> out from modem1<br>traffic from port 8002 -> out from modem2<br>...<br>...<br><br>I will
