Hello. I have just installed pfsense on hyper v. I have it setup like this.

ISP->ISP router->pfsense

I can access the lan on the isp router but i cant access the internet. The isp router is working fine, i know that. I have tried to change dns and so on. Does anyone know whart to do?

I'm going to assume that your ISP router is a router/modem combo?

 

If so, did you put it in bridge mode?

Nope, it dosent have that function, i'm using a private ip from the isp router as the wan on pfsense. But the wierd thing is that i cat access the internet, just pfsense lan and the isp routers lan. And yes, i have unchecked the setting that blocks private networks.

What type of connection do you have?

 

Just trying to visualize your setup.

 

So it's ISP modem -> ISP router -> Hyper-V server with Pfsense in VM -> lan ?

Yes

ISP modem-->ISP router-->Server with pfsense in hyper v (on the isp's router's lan)-->pfSense lan.

Why are you using the isp's router then?  You'd be double NATting.

 

Try: ISP modem to firewalled port on the pfsense nic, then the lan port to your switch/devices/ap (or however you are connecting your lan devices)

Can you get to the internet with a machine on the ISP router lan?

 

How are you connecting devices to pfsense if it’s virtualized?
