Allowing Internet Traffic for backend servers in fortiweb

[Daniyal007]

Hi there,

My query is regarding Forti web,

i have servers connected to the back of Forti web in reverse proxy mode but my backend server needs to connect to its update portal outside but can not connect.

is there any outgoing policy or any way to allow my specific server for allowing internet for updates.

Thanks

Hi @Daniyal007 

As you know ForiWeb is WAF/reverse proxy. Your server doesn't need to reach internet through FortiWeb. If the default GW for your server is the firewall then just add a firewall rule in you firewall to allow your server access the public update repositories.

i have set my server in one ARM mode means that server gateway is set on fortiweb

Does enabling Ip Forwarding feature requires down time because backend servers are in production.

[AEK]

Enabling the feature doesn't require downtime. But changing the config may do.

ok so i have to enable ip forwarding enable and then i have to configure SNAT. 

Does configuring SNAT my cause downtime ? because im not changing the server policy nor configuring anything except SNAT in firewall .

In theory it shouldn't impact since this is SNAT (for outbound traffic), which is different than the reverse proxy function. But let me double-check this before you do.

ok i am waiting for your confirmation

Tested successfully and there was no downtime.
