Internet not working

L1 Bithead

Hi Guys,
So we were using a router with two VLAN 10 and 20, connected to two different APs and everything was working fine.

Today we purchased a firewall and we placed it before the router (refer to the image). I created two static routes with Gateway and with the same Gateway. Still, we are not able to access the internet.

Any idea what I am doing wrong? Any other way to configure this whole setup?

- Check if the related interfaces are up and green on both side. Right Cable should connect to right interface 🙂

- Do you see related interface arp entry in both side Firewall and Router.

- Check İF config on Firewall are they belong to same virtual router.

-Check for defeault route in virtual router there should be to isp router faced interface and ip. 

-Try to ping internet from firewall, isp interface.

-Try to ping internet from firewall  mng. interface.

-Try to ping router from firewall if to router if.

-Check İnterface Config on Firewall ip adress is not a shadow object, create an address object than assing it.

-Check interface profile and allow ping. (You must write a rule)

-Check interface and Zone seetings related interface is assign to related Zone

-Check security policy create one any to any rule enable log start and log end to see whats hitting to firewall

-Check NAT Rules.



You can place firewall as Wirtual Wire mode 🙂


Have a nice day.
