Routing between two networks in Sophos home UTM 9.3

Hi,

So far with the Sophos community help I was able to fix the issues with my Home UTM configuration.

Now, I got another issue.

My Cable Internet router is in 192.168.0.1 range. So all my WiFi devices get that range.

My Sophos UTM LAN IP is in 172.17.0.1 range.

How/where do I create a route between these two IP ranges so that my LAN can talk to my WiFi.

I tried disabling the WiFi on the Cable router and connect another ADSL (Old router). assign the IP in 172 range.

But the problem is the Cable router is giving 34 MBPS on WiFi. If I connect the Old ADSL I am only getting 2.5 MBPS.

I don't want to buy another AP because of this.

If I can create a Route between 192 and 172 IP ranges the problem will be fixed.

Thank you,

Krishna

  • Do you have a cable modem that feeds the Sophos, or is it a WI-Fi router with the modem built in that feeds the Sophos?

    I have cat5 coming in from my ISP which feeds my Sophos. I take the ISP router and use it, behind the Sophos, as an AP/Switch only. I have no issues with speed, and I have no special firewall or NAT rules.

  • It is a Cable modem Built in Wi-Fi router.

  • If I understand correctly, you are using the WiFi from this router correct? If you do, that, the router will send the signal out to the Internet without going through the Sophos (bypassing all protection). I would turn that WiFi off and take another router or AP, on the same subnet as your internal network, and plug it in to the switch behind the Sophos. You will not need any special rules. Speed should not be an issue as the Sophos has nothing to do with connection speed to the WiFi. If you are getting poor download speeds over WiFi, that could be caused by several things two of which are easy to check out. Poor WiFi quality, or a noisy channel. I would check to see what channel your neighbors are on, and change yours to a less noisy one. As for checking the quality, you will need to compare it to different devices that you own, and see if you have a friend with a different AP that you can use. See what makes it better.

    Hope this helps.
