No external connectivity

Hello,

I just got a cable modem installed, it works, I have tested with a TP-link basic router and through it I can access the internet without a problem.

Then I tried setting an untangle server as a router, the internal interface works fine, but the external interface doesn't get a connection to the internet, I can't even ping the gateway.

I have tried changing the cable, remapping the interfaces in case a network card was faulty, I have checked the IP addresses lots of times, and I don't see where the problem may be.

The external interface is set as:

Config type: addressed

IPv4:

• Config type: static
• IP: 85.152.xx.xxx
• Mask: /25 - 255.255.255.128
• Gateway: 85.152.xx.xxx
• DNS server: 212.89.0.31

I guess I could set Untangle as a bridge behind the TP-link router but, since I want to activate OpenVPN, I would rather not.

Any idea what could be wrong?

Thanks
