Routing question

[athan1234]

Hello to everybody.

Muy customer currently has a default getway connection to an FW, which has a static routes to traffic to his Macrolan and internet routers.

My client wants to disable the FW and direct all traffic to the router's internet connection.

The plan is to set up a default gateway for the virtual IP of the router's internet connection and a vlan level 3 (for internet router) on the system. Those internet routers are directly connectin on the SW

Do you believe it is effective? I'm having trouble managing my connectivity.

I attach the currently FW set up

Hi @athan1234 

 The only thing you need to mind is if the internet router have router to return traffic to the internal vlans. Today probably it is  sending all return traffic to firewall, right?

 Another thing is NAT. If the firewall is doing NAT today, you need to transfer it to firewall.

And one last thing is the routing between internal vlans. If the firewall is the gateway today, it does the routing. You need to change the gateway to router.

Three points 

1- config defualt route toward the Internet router 

2- config NATing in Internet router for your vlan

3- config route for vlan in internet router this for return back traffic
