SRX5308: How config multiple static IPno's?

[adit]

I remember back when we just had the FVX538 and FVS336G as the only multi-WAN routers. We were specifically told not to connect multiple WAN ports to the same ISP router. It has to do with each WAN port having the same default gateway.

I haven't heard the question come up since then, since the answer was always "don't do it".

If you want to add additional WAN IP addresses for Services in the router, you just create the Inbound Rule and specify the WAN IP address.

Thanks adit! I've got a followup question for you
Btw, I have connected all 4 WAN ports of the SRX5308 to an ISP's gateway (an SMCD3G from Comcast) and attempted production enviroment for six months. The network experience was not great, but your feedback made me think of a possible workaround.
If the SRX5308 WAN ports cannot connect to the same gateway address, what if:
*On the gateway I enable dhcp with a range of only 1 assignable ip address
*On the srx5308 WAN2 settings I set it up with a "static" ip address of the sole assignable ip address on the gateway?
Obviously this would need to be worked out further, and I still haven't solved the problem of acquiring outbound static wan ip addresses for WAN3 and WAN4 on the srx5308, but it's something, right? Or no...?
The problem with only being able to assign INBOUND traffic based on static wan IPs, but then not being able to assign static wan IPs to OUTBOUND traffic, is that this creates an asynchronous environment which results in dropped packets!
For example, if establishing a secure connection to a vendor's website, many problems come from receiving packets on one ip but then replying from another ip. And what about ip whitelisting?
Thanks in advance for any help.

And what about ip whitelisting?

Prosecure UTM is what you want.

1 ISP router = 1 WAN. Else you will have problems.
