How to make outbound traffic to flow through an F5

Hi Craig,

 

 

That depends on your security requirements. Many customers use the same BIG-IP with separate VLANs to isolate networks. You could further isolate networks using route domains. Or for newer Viprions on 11.x, you could use vCMP to create virtual BIG-IP instances.

 

 

It might be worth talking with your F5 or partner SE to go over your exact scenario.

Craig - we host both DMZ and internal applications on a single pair. As Aaron stated, you can simply trunk multiple VLAN's to your BIG-IPs (one for your DMZ, one for your internal stuff, etc).

You can... But I wouldn't... Unless it's a Viprion and you're using separate vCMP guests for DMZ and internal.

 

 

You have firewalls between DMZ and internal for a reason. One of those is a single point of control. Having a single system 'bridge' the firewall like this can lead to security leaks.

It helps. But i still wouldnt bridge different levels of security like that. Bridging between zones of the same level i have done in the past. But dmz to internal is one i wouldnt do... Especially if a different team admin the firewall and bigip...
