Intial Setup Help

L0 Member

Hi everyone ... just bought a PA-200, and this is my first experience with this sort of device.  A little bit of a learning curve!

I am moving from a Barracuda Link Balancer.  This is my setup.

We have 5 public IP addresses, let's say for simplicity sake 173.61.106.10-14.  ISP gateway is 173.61.106.1.  We have FIOS and all 5 IPs come through 1 cable.  The cable goes into a switch.  One cable from the switch goes to the Barracuda.  The Barracuda manages IPs .10 .11 .12 on it's WAN port.  .13 goes to a Wifi device and .14 goes to our VOIP system.

We currently have traffic hitting all 3 public IPs on the Barracuda and being forwarded to our internal LAN.  I'd like to keep this as-is.

Couple of questions, because I've gotten conflicting info from the support people I have talked to thus far.

1.  Can you have multiple IP addresses on one interface, as I do above with the Barracuda?  If so, could I get some basic advise on how to set that up?  I've seen "use /32" and "use subinterface" and "you can't do that" on this discussion forum.  I'm hoping to get the final answer!

I think if I get the basics of how that would work, that will get me to my next questions.

Thanks in advance!

It is confusing, because you could use untagged subinterfaces to achieve the same thing. So there's more than one way to do it, which presents confusion Smiley Happy
